Cystic fibrosis-associated mutations at arginine 347 alter the pore architecture of CFTR. Evidence for disruption of a salt bridge. (1/4588)

Arginine 347 in the sixth transmembrane domain of cystic fibrosis transmembrane conductance regulator (CFTR) is a site of four cystic fibrosis-associated mutations. To better understand the function of Arg-347 and to learn how mutations at this site disrupt channel activity, we mutated Arg-347 to Asp, Cys, Glu, His, Leu, or Lys and examined single-channel function. Every Arg-347 mutation examined, except R347K, had a destabilizing effect on the pore, causing the channel to flutter between two conductance states. Chloride flow through the larger conductance state was similar to that of wild-type CFTR, suggesting that the residue at position 347 does not interact directly with permeating anions. We hypothesized that Arg-347 stabilizes the channel through an electrostatic interaction with an anionic residue in another transmembrane domain. To test this, we mutated anionic residues (Asp-924, Asp-993, and Glu-1104) to Arg in the context of either R347E or R347D mutations. Interestingly, the D924R mutation complemented R347D, yielding a channel that behaved like wild-type CFTR. These data suggest that Arg-347 plays an important structural role in CFTR, at least in part by forming a salt bridge with Asp-924; cystic fibrosis-associated mutations disrupt this interaction.  (+info)

Electrostatic interactions during activation of coagulation factor IX via the tissue factor pathway: effect of univalent salts. (2/4588)

Interaction between the Gla-domain of coagulation proteins and negatively charged phospholipid membranes is essential for blood coagulation reactions. The interaction is calcium-dependent and mediated both by electrostatic and hydrophobic forces. This report focuses on the electrostatic component of factor IX activation via the extrinsic pathway. Effective charges during the reaction are measured by ionic titration of activity, according to the Debye-Huckel and Gouy-Chapman models. Rates of activation decrease with ionic strength independently of the type of monovalent salt used to control ionic strength. Moreover, the effect of ionic strength decreases at concentrations of charged phospholipid approaching saturation levels, indicating that membrane charges participate directly in the ionic interaction measured. The effective charge on calcium-bound factor IX during activation on phospholipid membranes is 0.95+/-0.1. Possible sites mediating contacts between the Gla-domain and membranes are selected by geometrical criteria in several metal-bound Gla-domain structures. A pocket with a solvent opening-pore of area 24-38 A2 is found in the Gla-domain of factors IX, VII, and prothrombin. The pocket contains atoms with negative partial charges, including carboxylate oxygens from Gla residues, and has a volume of 57-114 A3, sufficient to accommodate additional calcium atoms. These studies demonstrate that electrostatic forces modify the activity coefficient of factor IX during functional interactions and suggest a conserved pocket motif as the contact site between the calcium-bound Gla-domain and charged membranes.  (+info)

An artificial transmembrane segment directs SecA, SecB, and electrochemical potential-dependent translocation of a long amino-terminal tail. (3/4588)

Many integral membrane proteins contain an amino-terminal segment, often referred to as an N-tail, that is translocated across a membrane. In many cases, translocation of the N-tail is initiated by a cleavable, amino-terminal signal peptide. For N-tail proteins lacking a signal peptide, translocation is initiated by a transmembrane segment that is carboxyl to the translocated segment. The mechanism of membrane translocation of these segments, although poorly understood, has been reported to be independent of the protein secretion machinery. In contrast, here we describe alkaline phosphatase mutants containing artificial transmembrane segments that demonstrate that translocation of a long N-tail across the membrane is dependent upon SecA, SecB, and the electrochemical potential in the absence of a signal peptide. The corresponding mutants containing signal peptides also use the secretion machinery but are less sensitive to inhibition of its components. We present evidence that inhibition of SecA by sodium azide is incomplete even at high concentrations of inhibitor, which suggests why SecA-dependent translocation may not have been detected in other systems. Furthermore, by varying the charge around the transmembrane segment, we find that in the absence of a signal peptide, the orientation of the membrane-bound alkaline phosphatase is dictated by the positive inside rule. However, the presence of a signal peptide is an overriding factor in membrane orientation and renders all mutants in an Nout-Cin orientation.  (+info)

Free energy landscapes of encounter complexes in protein-protein association. (4/4588)

We report the computer generation of a high-density map of the thermodynamic properties of the diffusion-accessible encounter conformations of four receptor-ligand protein pairs, and use it to study the electrostatic and desolvation components of the free energy of association. Encounter complex conformations are generated by sampling the translational/rotational space of the ligand around the receptor, both at 5-A and zero surface-to-surface separations. We find that partial desolvation is always an important effect, and it becomes dominant for complexes in which one of the reactants is neutral or weakly charged. The interaction provides a slowly varying attractive force over a small but significant region of the molecular surface. In complexes with no strong charge complementarity this region surrounds the binding site, and the orientation of the ligand in the encounter conformation with the lowest desolvation free energy is similar to the one observed in the fully formed complex. Complexes with strong opposite charges exhibit two types of behavior. In the first group, represented by barnase/barstar, electrostatics exerts strong orientational steering toward the binding site, and desolvation provides some added adhesion within the local region of low electrostatic energy. In the second group, represented by the complex of kallikrein and pancreatic trypsin inhibitor, the overall stability results from the rather nonspecific electrostatic attraction, whereas the affinity toward the binding region is determined by desolvation interactions.  (+info)

Charge pairing of headgroups in phosphatidylcholine membranes: A molecular dynamics simulation study. (5/4588)

Molecular dynamics simulation of the hydrated dimyristoylphosphatidylcholine (DMPC) bilayer membrane in the liquid-crystalline phase was carried out for 5 ns to study the interaction among DMPC headgroups in the membrane/water interface region. The phosphatidylcholine headgroup contains a positively charged choline group and negatively charged phosphate and carbonyl groups, although it is a neutral molecule as a whole. Our previous study (Pasenkiewicz-Gierula, M., Y. Takaoka, H. Miyagawa, K. Kitamura, and A. Kusumi. 1997. J. Phys. Chem. 101:3677-3691) showed the formation of water cross-bridges between negatively charged groups in which a water molecule is simultaneously hydrogen bonded to two DMPC molecules. Water bridges link 76% of DMPC molecules in the membrane. In the present study we show that relatively stable charge associations (charge pairs) are formed between the positively and negatively charged groups of two DMPC molecules. Charge pairs link 93% of DMPC molecules in the membrane. Water bridges and charge pairs together form an extended network of interactions among DMPC headgroups linking 98% of all membrane phospholipids. The average lifetimes of DMPC-DMPC associations via charge pairs, water bridges and both, are at least 730, 1400, and over 1500 ps, respectively. However, these associations are dynamic states and they break and re-form several times during their lifetime.  (+info)

pH-dependent conformational change of gastric mucin leads to sol-gel transition. (6/4588)

We present dynamic light scattering (DLS) and hydrophobic dye-binding data in an effort to elucidate a molecular mechanism for the ability of gastric mucin to form a gel at low pH, which is crucial to the barrier function of gastric mucus. DLS measurements of dilute mucin solutions were not indicative of intermolecular association, yet there was a steady fall in the measured diffusion coefficient with decreasing pH, suggesting an apparent increase in size. Taken together with the observed rise in depolarized scattering ratio with decreasing pH, these results suggest that gastric mucin undergoes a conformational change from a random coil at pH >/= 4 to an anisotropic, extended conformation at pH < 4. The increased binding of mucin to hydrophobic fluorescent with decreasing pH indicates that the change to an extended conformation is accompanied by exposure of hydrophobic binding sites. In concentrated mucin solutions, the structure factor S(q, t) derived from DLS measurements changed from a stretched exponential decay at pH 7 to a power-law decay at pH 2, which is characteristic of a sol-gel transition. We propose that the conformational change facilitates cross-links among mucin macromolecules through hydrophobic interactions at low pH, which in turn leads to a sol-gel transition when the mucin solution is sufficiently concentrated.  (+info)

Selectivity and permeation in calcium release channel of cardiac muscle: alkali metal ions. (7/4588)

Current was measured from single open channels of the calcium release channel (CRC) of cardiac sarcoplasmic reticulum (over the range +/-180 mV) in pure and mixed solutions (e.g., biionic conditions) of the alkali metal ions Li+, K+, Na+, Rb+, Cs+, ranging in concentration from 25 mM to 2 M. The current-voltage (I-V) relations were analyzed by an extension of the Poisson-Nernst-Planck (PNP) formulation of electrodiffusion, which includes local chemical interaction described by an offset in chemical potential, which likely reflects the difference in dehydration/solvation/rehydration energies in the entry/exit steps of permeation. The theory fits all of the data with few adjustable parameters: the diffusion coefficient of each ion species, the average effective charge distribution on the wall of the pore, and an offset in chemical potential for lithium and sodium ions. In particular, the theory explains the discrepancy between "selectivities" defined by conductance sequence and "selectivities" determined by the permeability ratios (i.e., reversal potentials) in biionic conditions. The extended PNP formulation seems to offer a successful combined treatment of selectivity and permeation. Conductance selectivity in this channel arises mostly from friction: different species of ions have different diffusion coefficients in the channel. Permeability selectivity of an ion is determined by its electrochemical potential gradient and local chemical interaction with the channel. Neither selectivity (in CRC) seems to involve different electrostatic interaction of different ions with the channel protein, even though the ions have widely varying diameters.  (+info)

Adhesion energy of receptor-mediated interaction measured by elastic deformation. (8/4588)

We investigated the role of receptor binding affinity in surface adhesion. A sensitive technique was developed to measure the surface energy of receptor-mediated adhesion. The experimental system involved a functionalized elastic agarose bead resting on a functionalized glass coverslip. Attractive intersurface forces pulled the two surfaces together, deforming the bead to produce an enlarged contact area. The Johnson-Kendall-Roberts (JKR) model was used to relate the surface energy of the interaction to the elasticity of the bead and the area of contact. The surface energies for different combinations of modified surfaces in solution were obtained from reflection interference contrast microscopy (RICM) measurements of the contact area formed by the bead and the coverslip. Studies with surfaces functionalized with ligand-receptor pairs showed that the relationship between surface energy and the association constant of the ligand binding has two regimes. At low binding affinity, surface energy increased linearly with the association constant, while surface energy increased logarithmically with the association constant in the high affinity regime.  (+info)

The chemical, or chemisorption, part of colloidal interaction free energy is revisited. Consistent incorporation of nonelectrostatic interactions in the chemical potential for the constant potential and charge regulation boundary conditions is developed. This gives rise to shifted adsorption equilibria, and thereby a shift in the predicted surface electrostatic potential. It also results in an additional component previously unaccounted for in the total double layer interaction force. The altered force leads to the need of recalibrating electrostatic surface potentials and equilibrium constants when fitting to experimental force data. A numerical illustration is presented using ionic dispersion potentials for mica surfaces interacting across NaCl at various concentrations. The new force component due to ionic dispersion is typically repulsive and exceeds entropic repulsion in magnitude. These results suggest that the effect of ionic dispersion is more profound than previously believed, even at ...

We explored the influence of external electric fields (EEFs) on the stability of a glycine dipeptide model radical using high-level quantum chemical methods. Remotely located ions (Cl-/Na+) are used to implement EEF effects. The effects of these ions are reproduced using background point charges and oriented EEFs. Remote charges as far as 900 pm from the C-alpha radical center can be significantly stabilizing or destabilizing as a function of their relative orientation. The magnitude of these effects is also strongly dependent on the distance between the radical center and the charge location. After examining the strengths and weaknesses of some frequently used quantum mechanics methods in describing these effects properly, a comparison is made on the stability of dipeptide radicals bearing protonable or deprotonable side chains. In this group, the stability of the respective C-alpha radicals mainly depends on the preferred orientation of the charge-carrying side chain. ...

High dielectric contrast between water and hydrocarbons provides a useful method for distinguishing between producible layers of reservoir rocks and surrounding media. Dielectric response at high frequencies is related to the moisture content of rocks. Correlations between the dielectric permittivity and specific surface area can be used for the estimation of elastic and geomechanical properties of rocks. Knowledge of dielectric loss-factor and relaxation frequency in shales is critical for the design of techniques for effective hydrocarbon extraction and production from unconventional reservoirs. Although applicability of dielectric measurements is intriguing, the data interpretation is very challenging due to many factors influencing the dielectric response. For instance, dielectric permittivity is determined by mineralogical composition of solid fraction, volumetric content and composition of saturating fluid, rock microstructure and geometrical features of its solid components and pore space,

Abstract: We investigate the spectral and transport properties of parallel double-quantum-dot (DQD) system with interdot tunneling coupling in both the equilibrium and nonequilibrium cases. The special geometry of DQD system is considered, in which each dot is connected to two leads by the tunneling barriers. With the help of Keldysh nonequilibrium Green function technique and the equation-of-motion approach, the spectral function and the conductance spectra of DQD system are calculated in two cases with and without the intradot Coulomb interaction, respectively. The exact calculation is performed in the absence of intradot Coulomb interaction. For the case with intradot Coulomb interaction, the Hartree-Fock approximation is applied to truncate the equation of motion for the high-order Green functions at high temperatures. The phenomenon of correlated electron transport is clearly shown in the linear conductance of each dot in the presence of interdot tunneling when setting one dot level and ...
In his editorial, Andersen 1999 questions the applicability of the mean field approximation for the situation of ions in the narrow pore of the channel: Finally, notwithstanding the utility of the mean field approximation, is it appropriate for narrow channels that are occupied by only a few ions? Similar doubts are mentioned in other Perspectives. Therefore, a critical inspection of the concepts of mean fields and mean field approximation in statistical physics applied to biological ion channels is timely. Whereas the introduction of mean fields generally does not involve any approximation, the mean field approximation is necessary to account for the nonlinear long-range electrostatic interaction between permeant ions..

Strong electrostatic interactions such as zwitterionic pairing between oppositely charged amino acids are common in the condensed phase at neutral pH and can play a large role in determining the conformational landscape of peptides and proteins. Whether such interactions are possible in the absence of solvent however, has been previously debated. Growing experimental evidence suggests that these interactions are indeed possible in isolated gas phase ions and may give rise to unique fragmentation upon UV irradiation. In this study we use a series IR-UV-IR triple resonance techniques performed at 10 K to investigate the influences of these electrostatic interactions on the electronic and structural properties of model YGRXR ( X = gly, asp) pentapeptide systems and their methyl ester counterparts.

Cámara CL & N Wilke, Chem. Phys. Lipids, 2017 Polysaccharides have been associated with various biological functions through their binding to membranes, but their specific role is still under debate. The aim of this work was to study the interaction of cationic and anionic polysaccharides with anionic and zwitterionic monolayers, at different subphase compositions, thus analyzing the influence of electrostatics on the interaction. The consequent effect of the polymer-lipid binding on the film properties was studied, with special interest in monolayer dynamics. The results indicate that electrostatic interactions play an important role in polymer-membrane affinity, and that the polymers formed a sub-layer, which increased the shear viscosity of the interface. The interacting polymer, even when it did not penetrate the lipid film, induced a polymer-like behavior of the monolayer regarding its dynamics: the whole film (polymer+lipid) became very viscous. As a consequence, the dynamic of the ...

Understanding how the mechanism of charge transport through molecular tunnel junctions depends on temperature is crucial to control electronic function in molecular electronic devices. With just a few systems investigated as a function of bias and temperature so far, thermal effects in molecular tunnel junctions remain poorly understood. Here we report a detailed charge transport study of an individual redox-active ferrocene-based molecule over a wide range of temperatures and applied potentials. The results show the temperature dependence of the current to vary strongly as a function of the gate voltage. Specifically, the current across the molecule exponentially increases in the Coulomb blockade regime and decreases at the charge degeneracy points, while remaining temperature-independent at resonance. Our observations can be well accounted for by a formal single-level tunnelling model where the temperature dependence relies on the thermal broadening of the Fermi distributions of the electrons in the

AU - Uchimaru, Tadafumi. AU - Korchowiec, Jacek. AU - Tsuzuki, Seiji. AU - Matsumura, Kazunari. AU - Kawahara, Shun Ichi. PY - 2000/2/18. Y1 - 2000/2/18. N2 - We have examined the energy components of hydrogen-bonding interactions by using self-consistent charge and configuration method for subsystems (SCCCMS) and charge sensitivity parameters. Our procedure indicated that the main source of the stabilization for hydrogen-bonding association was the electrostatic contribution. The secondary electrostatic and polarization interactions due to polar functional groups located closely to the hydrogen-bonding sites were shown to significantly alter the magnitude of hydrogen-bonding stabilization. This finding supports Jorgensen and co-workers interpretation toward the hydrogen-bonding energies [e.g., W.L. ...

Many existing carriers encapsulate drugs through the long-range electrostatic interactions - the carrier attracts oppositely charged medicine. Our method does not deal with the electrostatics at all. Filling in the nanogel by the guest molecules, locking them in the cavity and further release arecontrolled by the temperature. Therefore, the medicines themselves can be both charged and neutral, says one of the Russian co-authors of the article, Professor Igor Potemkin. According to the authors, there are other tools to trigger the release of drugs, for example, an external magnetic field and pH. But in each case researchers face the problem of efficiency of the drug release.. The scientists decided to use the gel nano-capsules that were previously undervalued as the carrier systems. Their main problem, which held back the interest towards them, was that the capsules stuck together with their neighbors (lost colloidal stability) when trying to upload drugs. Such behavior made the delivery ...
TY - CONF. T1 - Solvent Models - A way to connect He-DFT with standard ab initio techniques?. AU - Hauser, Andreas. AU - Ernst, Wolfgang E.. PY - 2015/3/21. Y1 - 2015/3/21. N2 - Typical quantum chemistry packages know several implicit solvent models, differing greatly in their level of sophistication. First or second solvation shells might be still accessible via super-molecular calculations and averaging over different He geometries, but such an approach does not take into consideration any long-range interactions. For example, an alkali atom, embedded in a He-nanodroplet, should have a solvation energy ofseveral hundred wavenumbers. In standard solvation models, this flaw is repaired by the self-consistent reaction field technique (SCRF), where the continuum solvent establishes a reaction field, which itself depends on the electron density of the solute or dopant molecule.This talk aims at the question whether modified versions of known techniques such as the Kirkwood-Onsager model, the ...
The COSMO-RS method was used for calculation of blood-brain partition coefficients based on sigma-moments. These five sigma moments are: surface area of the solute, the negative of the total charge, another noment corresponds to the negative of the electrostatic interaction energy of the solute with a dielectric continuum, and the third-order moment does not have a simple interpretation plus acceptor and donor moments.. The calculation and interpretation of large descriptor datasets can be avoided and the quantum chemical definition of the sigma-moments is applicable to almost all kinds of organic compounds. A minor disadvantage is the computational time for new compounds which includes quantum mechanical calculations (10 min per compound), however this can be diminished by using compute clusters or COSMOfrag a precalculated dataset of sigma-profiles).. ...
The extrapolation of small-cluster exact-diagonalization calculations and the Monte Carlo method is used to study the spin-one-half Falicov-Kimball model extended by the spin-dependent Coulomb interaction (J) between the localized f and itinerant d electrons as well as the on-site Coulomb interaction (U_{ff}) between the localized f electrons. It is shown that in the symmetric case the ground-state phase diagram of the model has an extremely simple structure that consists of only two phases, and namely, the charge-density-wave phase and the spin-density-wave phase. The nonzero temperature studies showed that these phases persist also at finite temperatures. The same calculations that we performed for unsymmetric case showed that charge and spin ordering can be destroyed simultaneously or consecutively ...
The Adsorption Characteristics of NI (II) Onto Bubble Surface. The removal of Ni(II) by foam fractionation is brought about by the electrostatic mechanism. From removal and zeta potential measurements, it clearly demonstrates that Ni**2** plus and NiOH** plus ions become associated with the dodecylsulfonate coated (negative charge) N//2 gas bubbles. The optimal Ni(II) to NaDS (molar ratio) is 0. 2. The Ni**2** plus species forms moderately strong complexes with dodecylsulfonate ions.
Whole-proteome distributions of protein isoelectric point (pI) values in different organisms are bi- or trimodal with some variations. It was suggested that the observed multimodality of the proteome-wide pI distributions is associated with subcellular localization-specific differences in the local pI distributions. However, the factors responsible for variation of the intracellular localization-specific pI profiles have not been investigated in detail. In this work, we explored proteome-wide pI distributions of 32,138 human proteins predicted to reside in 10 subcellular compartments, as well as the pI distributions of experimentally observed lysosomal and Golgi proteins. The distributions were found to differ significantly, although all of them adhered to the major recurrent bimodal pattern. Grossly, acid-biased and alkaline-biased patterns with various minor statistical features were observed at different subcellular locations. Bioinformatics analysis revealed the existence of strong statistically
TY - JOUR. T1 - Electrostatic effects in DNA bending by GCN4 mutants. AU - Strauss-Soukup, Juliane K.. AU - Maher, L. James. PY - 1998/1/27. Y1 - 1998/1/27. N2 - DNA architecture has been shown to be important for cellular processes such as activation of transcription, recombination, and replication. Many proteins reconfigure the shape of duplex DNA upon binding. Previous experiments have shown that some members of the eukaryotic bZIP family of DNA binding proteins appear to bend DNA, while others do not. We are exploring the role of electrostatic effects in DNA bending by bZIP proteins. The yeast bZIP transcription factor GCN4 does not induce DNA bending in vitro. Previously we substituted basic residues for three neutral amino acids in GCN4 to produce a CJCN4 derivative that bends DNA by ~ 15°. This result is consistent with a model of induced DNA bending wherein excess positive charge in proximity to one face of the double helix neutralizes local phosphate diester anions resulting in a ...
Measured values of the swelling pressure of charged proteoglycans (PG) in solution (Williams RPW, and Comper WD; Biophysical Chemistry 36:223, 1990) and the ionic strength dependence of the equilibrium modulus of PG-rich articular cartilage (Eisenberg SR, and Grodzinsky AJ; J Orthop Res 3: 148, 1985) are compared to the predictions of two models. Each model is a representation of electrostatic forces arising from charge present on spatially fixed macromolecules and spatially mobile micro-ions. The first is a macroscopic continuum model based on Donnan equilibrium that includes no molecular-level structure and assumes that the electrical potential is spatially invariant within the polyelectrolyte medium (i.e. zero electric field). The second model is based on a microstructural, molecular-level solution of the Poisson-Boltzmann (PB) equation within a unit cell containing a charged glycosaminoglycan (GAG) molecule and its surrounding atmosphere of mobile ions. This latter approach accounts for the ...
The protonation state of embedded charged residues in transmembrane proteins (TMPs) can control the onset of protein function. It is understood that interactions between an embedded charged residue and other charged or polar residues in the moiety would influence its pKa, but how the surrounding environment in which the TMP resides affects the pKa of these residues is unclear.

Control over the motional degrees of freedom of atoms, ions, and molecules in a field-free environment enables unrivalled measurement accuracies but has yet to be applied to highly charged ions (HCIs), which are of particular interest to future atomic clock designs and searches for physics beyond the Standard Model. Here, we report on the Coulomb crystallization of HCIs (specifically 40Ar13+) produced in an electron beam ion trap and retrapped in a cryogenic linear radiofrequency trap by means of sympathetic motional cooling through Coulomb interaction with a directly laser-cooled ensemble of Be+ ions. We also demonstrate cooling of a single Ar13+ ion by a single Be+ ion-the prerequisite for quantum logic spectroscopy with a potential 10−19 accuracy level. Achieving a seven-orders-of-magnitude decrease in HCI temperature starting at megakelvin down to the millikelvin range removes the major obstacle for HCI investigation with high-precision laser spectroscopy.. ...
This is the approach we use in this work. By integrating CPW TLines on top of porous Si and measuring their S-parameters, we extract porous Si. dielectric parameters by combining the experimental results with electromagnetic simulations and conformal mapping calculations. This method has been described in detail in [13, 14], and the results have been proven to be in very good agreement with full-wave EM simulations [14]. In Figure 4 the extracted dielectric permittivity of three PSi layers with 70%, 76%, and 84% porosity using the above method are depicted in full black circles. The PSi layers were fabricated on a p+-type Si wafer with resistivity 1 to 5 mΩ.cm and had a surface area of 4 cm2. NU7026 Identical transmission lines were integrated on all three samples (see Figure 2b). The obtained results were compared with those obtained using Vegards, Maxwell-Garnetts and Bruggemans models for PSi by applying formulas (1) to (3) given above. From Figure 4, it can be seen that the values of the ...

Industrys need to predict the lifetime of adhesively bonded joints has been met by the development of a wide variety of techniques. One particular approach utilises the fact that adhesives and the joints they form can be susceptible to moisture attack. The ingress of moisture into, and through, an adhesive or polymer is termed water permeation. Such a phenomenon can be measured extremely accurately (e.g. through mass change, dielectric permittivity, etc) and it has been shown that for particular systems and environments, a good correlation can be made between the accelerated ageing protocol and in-service failure. This approach has been studied extensively for application within the electronics sector where adhesive/polymeric systems are used both to retain components and coat them. ...

We will probe the interaction induced by lipid membranes between included molecules (and other nano-objects). This study presents both a fundamental interest, from the point of view of soft matter physics, and a relevance to understanding the activity of important biological molecules, such as native membrane proteins and antimicrobial peptides. In particular, the cytotoxic activity of the latter is directly related to the composition of the membrane (charge, thickness, presence of cholesterol) rather than to specific chemical recognition. It has long been posited that highly simplified descriptions (e.g. in terms of hydrophobic matching) capture the essence of the process, but the extensive body of theoretical and numerical work cannot be validated and refined due to the lack of experimental results. We intend to measure accurately the interaction between membrane inclusions. Highly aligned lipid multilayers, doped with antimicrobial peptides and fully hydrated (in excess water) will be studied using

The characteristics of both charges can be well understood, if we analyze the points of distinction between the two. They are as follows:. 1. A fixed charge is created on some property capable of being defined. A floating charge, on the other hand, shall be generally created upon the whole of the companys property, including movable and immovable and also property, which is subject to a fixed charge.. 2. The company cannot deal with a property, which is subject to a fixed charge. But, it can deal with all the properties, which are subject to a floating charge.. 3. A fixed charge shall not become a floating charge. A floating charge, upon the occurrence of certain events may become a fixed charge.. 4. If a fixed charge is created over a property, which is subject to a floating charge, the fixed charge shall get priority, whereas if a floating charge is created over the assets, which are subject to a fixed charge, the charges shall not get any priority.. ...

The importance of electrostatic interactions in soft matter and biological systems can often be traced to non-uniform charge effects, which are commonly described using a multipole expansion of the corresponding charge distribution. The standard approach when extracting the charge distribution of a given system is to treat the constituent charges as points. This can, however, lead to an overestimation of multipole moments of high order, such as dipole, quadrupole, and higher moments. Focusing on distributions of charges located on a spherical surface - characteristic of numerous biological macromolecules, such as globular proteins and viral capsids, as well as of inverse patchy colloids - we develop a novel way of representing spherical surface charge distributions based on the von Mises-Fisher distribution ...

Im sorry, but why did you need to consider A and B rather than A and C? I figured Id have to find the electric field due to A at a distance of 2r+dr, due to C at a distance of r-dr and sum them? Also why were you able to drop the subsequent [itex]dr^{2}[/itex] terms? i figured that despite differential notation being used, nowhere in the problem statement did they actually say the displacement was infinitesimal so I wasnt confident discarding dr terms ...
The electron transport properties of single crystalline metallic nanostructures in the Coulomb blockade regime have been investigated by low-temperature scanning tunneling spectroscopy. To this end, nanoscale flat-top Pb islands with well-defined geometries are grown on NaCl-covered Ag(111) substrate. The tunneling spectra acquired at 4.6 K on the Pb nanoislands reflect the presence of single electron tunneling processes across the double-barrier tunnel junction (DBTJ). By a controlled change of the tip-island tunnel distance, the spectra display the characteristic evolution from Coulomb blockade (CB) to Coulomb staircase (CS) regime. Simulations within the semi-classical orthodox theory allow us to extract quantitatively the parameters characterizing the DBTJ, i. e., the resistances, capacitances, and the residual charge Q0. Manipulation of Q0 is achieved by controlled application of voltage pulses on the Pb islands. Moreover, under specific tunneling conditions, the influence of the tip-island
A shell with one or two electrons is keen to lose electrons, so they are stable - become a positive ion. - A nearly full shell keen to gain electrons to become stable - become negative ions. - Ions are very reactive, be easily attracted to passing ions with opposite charge. Ionic bonds between metals and non-metals produce giant ionic structures. - closely packed in lattice. Ions are not free to move so do not conduct electricity when solid.. - Very strong chemical bonds between all ions. e.g MgO and NaCl. - High melting points bc of strong attraction. - MgO has higher MP than NaCl because its made of Mg^2+ and O^2- ions, so double charge. ...
One must not confuse the dielectric constant of a solvent with its dipole moment. The dipole moment of a solvent, or of any covalent compound, is a microscopic property, meaning it is a property of the molecule of the compound. In contrast, the dielectric constant of a solvent is a a macroscopic property, meaning it is a property of a pure sample of the solvent. Given below is the scattergram of the dielectric constants of sixteen solvents against their dipole moments, showing that there is no clear correlation between the dielectric constant of a solvent and its dipolar moment.. ...

The main current proponent of scalar wave pseudophysics is zero-point energy advocate Thomas E. Bearden, who has concocted an entire pseudoscientific scalar field theory unrelated to anything in actual physics of that name. It starts with Maxwells equations originally having been written as quaternions; Bearden holds that the (mathematical) transformation to vectors lost important information.[1] Bearden says that scalar waves differ from conventional electromagnetic transverse waves by having two oscillations anti-parallel with each other, each originating from opposite charge sources, thereby lacking any net directionality. The waves are conjugates of each other, and so, if left unperturbed, can pass through ordinary matter with relative ease. So they are not included in mainstream physics. They dont work like ordinary longitudinal waves either. (Got that?)[6] You can apparently make scalar waves with a bifilar coil (one wound with a pair of wires instead of a single wire) and pushing ...
By averaging over pairs of hyperspheres, we have obtained the dielectric function for a binary mixture containing hyperspherical inclusions up to order c2, where c is the volume fraction of inclusions. The method used is based on multipole expansions for the potential of two spheres in a uniform field and is a generalization of the method of Jeffrey to d-dimensional space. Numerical results are presented for the second-order coefficient κ in the low-c expansion of the dielectric constant for arbitrary d; these verify earlier known results, as well as showing the dependence of κ on dimensionality, which is particularly simple as d → 1 and as d → ∞. ...

  • But when two materials rub together (like your hair and your cap) some of the electrons jump from one thing to the other, creating an electric charge called static electricity. (
  • Ans: Electricity is the movement of electrons. (
  • When contact between two materials generates friction, a static charge can result because electrons might get stripped off of one surface and transported onto another. (
  • When you touch an object with a static charge, you can get shocked because you give those electrons a chance to leap across to your finger. (
  • Static electricity is caused by an imbalance of electrons on a surface. (
  • Electricity is created by teeny tiny particles called protons and electrons. (
  • In high school physics classes, students are often taught that static electricity develops when electrons detach from the surface of one object and jump to another, causing a difference in charge. (
  • But new research published in the journal Science shows that static electricity is caused by more than just the exchange of individual electrons, and instead involves the transfer of bigger (yet still tiny) clumps of material. (
  • Scientists conventionally believed that static electricity required friction between two different non-metals, which would tug at their electrons with different amounts of force. (
  • As far as the exchange of material other than electrons, how many tens or hundreds of thousands of high school physics students have experimented with "static" electricity by putting two pieces of scotch tape together, then rapidly separating them? (
  • So more electrons hop from plane to sphere than vice versa, leaving the sphere negatively charged and the plane positively charged and creating the static. (

  • These atoms that are charged with electricity are made out of a nucleus and electrons that surround it. (
  • DICTIONARY DEFINITION Static Electricity: A charge of an object caused by the addition or removal of electrons Hannah: Hey robot, could you please give me n example of static electricity? (
  • Electricity is simply the flow of electrons from one point to another. (
  • The result of an imbalance of this 'fluid' (electrons) between objects is called static electricity. (
  • It is called 'static' because the displaced electrons tend to remain stationary after being moved from one insulating material to another. (
  • What we observe as electricity or static electric charge is the macro or bulk effect of all the electrons in the body. (
  • Conversely, for significant static electricity to be generated, at least one of the materials must have a high resistance to the flow of electrons (be an insulator). (
  • Technically, electricity is actually a phenomenon in itself, which involves the displacement or movement of electrons. (
  • Current electricity, on the other hand, is a phenomenon of moving electrons in a particular path, or direction, such as a stream of them flowing through conducting materials. (
  • 1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. (
  • 2. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity. (
  • becuase electrons are getting scraped off and this leaves static charges on both you and the jumper. (
  • Static charge builds up when an object's surface has lost a lot of electrons and builds up a positive charge. (
  • See the page for neutral because Static electricity When two objects are rubbed together, electrons are transferred from one object to the other. (
  • Static electric charge arose from the friction of the OHP foil with the components in the copier. (
  • I've taught physics at the high school level for 11 years, and have never taught that friction causes "static" electricity. (
  • The most common cause of static electricity is the contact and immediate separation of the two materials that is friction, winding, and unwinding. (
  • Static electricity is generated by friction, or sudden contact - for instance, rubbing two materials against each other. (
  • Three main conditions are responsible for causing static electricity: friction, separation, and induction. (
  • I use this lesson near the beginning of the electricity unit in SNC1D1, after introducing static electricity and charging by friction, contact and induction. (
  • Static electricity can be created through the friction between two materials - for instance a wool cap and a plastic ruler. (
  • Static and dynamic friction.Kinetic and potential energy. (

  • The familiar phenomenon of a static shock - more specifically, an electrostatic discharge - is caused by the neutralization of charge. (
  • Wikipedia) Items that are very sensitive to static discharge can be treated with an antistatic agent. (
  • Why Does a Static Electric Discharge Make a Sound and Light? (
  • Items that are particularly sensitive to static discharge may be treated with the application of an antistatic agent, which adds a conducting surface layer that ensures any excess charge is evenly distributed. (
  • Many semiconductor devices used in electronics are particularly sensitive to static discharge. (
  • Lightning is a form of static discharge. (
  • Those objects keep a static charge until they find a way to be released or until neutralized by a discharge. (
  • Static electricity is not good for computer components because the discharge current generates heat. (
  • Static electricity is a reference to the electric charge of an object and the related electrostatic discharge when two objects are brought together that are not at equilibrium. (
  • The static charges remains on an object until they either bleed off to ground or are quickly neutralized by a discharge. (
  • Usually, the worst possible effect of a static discharge to the case, keyboard, or even a location near the computer is a system lockup. (
  • appropriate equipment so as to mitigate the risks associated with static electricity/lightning and potential discharge resulting in product/process misbehaviour or fires, explosions and injury to personnel. (
  • Static electricity discharge is a major contributor to EMI problems, especially in the autumn when the relative humidity begins to drop. (
  • This includes lightning, discharge from the human body and furniture discharge which, because it does not travel through your body, is the invisible form of static discharge and in reality the most common and insidious. (
  • Static discharge has two basic components, radio frequency interference, RFI, and the pulse of electricity conducted into the surface of your computer when you touch the case. (
  • by Ron Kurtus (revised 18 May 2017) Static electricity is the buildup of electrical charges on the surface of some object or material. (
