In recent decades, thermodynamics has attained a remarkable level of competence in advanced design of practical devices, complex energy and industrial systems, bioprocesses, chemical reactors, reacting flows, separations, and even (most recently) flying objects. One of the key concepts of nonequilibrium thermodynamics is that it can take account of dynamic behavior and pathwise constraints. Some recent developments in thermodynamics, aimed at extending the range of its application to far-from equilibrium regimes (extended thermodynamics, only briefly discussed in the book) abandon the assumption of local equilibrium. Consequently problems in nonequilibrium thermodynamics are formulated as typical or extended macroscopic problems of thermodynamic networks or fields. New developments consider also various aspects of material structure, in particular polymeric fluids and rheological bodies described by general rheological equations of state and bodies with continuous spectra. Still other ...

SECOND LAW OF THERMODYNAMICS Thermodynamics Summary The important information from this chapter is summarized below. Second Law of Thermodynamics Summary Planck s statement of the Second Law of Thermodynamics is: It is impossible to construct an engine that will work in a complete cycle and produce no other effect except the raising of a weight and the cooling of a heat reservoir. The Second Law of Thermodynamics demonstrates that the maximum possible efficiency of a system is the Carnot efficiency written as: h = (TH - TC)/TH The maximum efficiency of a closed cycle can be determined by calculating the efficiency of a Carnot cycle operating between the same value of high and low temperatures. The efficiency of a component can be calculated by comparing the work produced by the component to the work that would have been produced by an ideal component operating isentropically between the same inlet and outlet conditions. An isentropic expansion or compression process will be represented as a ...
Statistical thermodynamics of residue fluctuations of native proteins in a temperature, pressure, and force reservoir is formulated. The general theory is discussed in terms of harmonic and anharmonic fluctuations of residues. The two elastic network models based on the harmonic approximation, the anisotropic network and the Gaussian network models are discussed as the limiting cases of the general theory. The heat capacity and the correlations between the energy fluctuations and residue fluctuations are obtained for the harmonic approximation. The formulation is extended to large fluctuations of residues in order to account for effects of anharmonicity. The fluctuation probability function is constructed for this purpose as a tensorial Hermite series expansion with higher order moments of fluctuations as coefficients. Evaluation of the higher order moments using the proposed statistical thermodynamics model is explained. The formulation is applied to a hexapeptide and the fluctuations of ...
In a wide variety of thermal energy systems, the high integration among components derives from the need to correctly exploit all the internal heat sources by a proper matching with the internal heat sinks. According to what has been suggested in previous works to address this problem in a general way, a basic configuration can be extracted from the system flowsheet including all components but the heat exchangers, in order to exploit the internal heat integration between hot and cold thermal streams through process integration techniques. It was also shown how the comprehension of the advanced thermodynamic cycles can be strongly facilitated by decomposing the system into elementary thermodynamic cycles which can be analyzed separately. The advantages of the combination of these approaches are summarized in this paper using the steam injected gas turbine (STIG) cycle and its evolution towards more complex system configurations as an example of application. The new concept of baseline thermal ...

The theory of classical or equilibrium thermodynamics is idealized. A main postulate or assumption, often not even explicitly stated, is the existence of systems in their own internal states of thermodynamic equilibrium. In general, a region of space containing a physical system at a given time, that may be found in nature, is not in thermodynamic equilibrium, read in the most stringent terms. In looser terms, nothing in the entire universe is or has ever been truly in exact thermodynamic equilibrium.[59][60]. For purposes of physical analysis, it is often enough convenient to make an assumption of thermodynamic equilibrium. Such an assumption may rely on trial and error for its justification. If the assumption is justified, it can often be very valuable and useful because it makes available the theory of thermodynamics. Elements of the equilibrium assumption are that a system is observed to be unchanging over an indefinitely long time, and that there are so many particles in a system, that its ...

In this paper we make the assertion that the key to understand the emergent properties of excitable tissue (brain and heart) lies in the application of irreversible thermodynamics. We support this assertion by pointing out where symmetry break, phase transitions both in structure of membranes as well as in the dynamic of interactions between membranes occur in excitable tissue and how they create emergent low dimensional electrochemical patterns. These patterns are expressed as physiological or physiopathological concomitants of the organ or organism behavior. We propose that a set of beliefs about the nature of biological membranes and their interactions are hampering progress in the physiology of excitable tissue. We will argue that while there is no direct evidence to justify the belief that quantum mechanics has anything to do with macroscopic patterns expressed in excitable tissue, there is plenty of evidence in favor of irreversible thermodynamics. Some key predictions have been fulfilled long

The Second Law of Thermodynamics is stateed as follows in wikipedia: The entropy of an isolated system consisting of two regions of space, isolated from one another, each in thermodynamic equilibrium in itself, but not in equilibrium with each other, will, when the isolation that separates the two regions is broken, so that the two regions become able to exchange matter or energy, tend to increase over time, approaching a maximum value when the jointly communicating system reaches thermodynamic equilibrium. In more practical terms, I have defined the second law of thermodynamics with the two corresponding ideas: 1) In a closed systems, entropy will increase. Conversely, in open systems, entropy will tend to increase. 2 ) If energy is inputted into a system and a state change occurs, the result of the change will be simpler/less ordered than the original participants. Conversely, if energy dissipates from a system and state-change occurs, the result is more complex/more ordered than the original

Efficiency of Machines; 11. Thermodynamics is a branch of physics which deals with the energy and work of a system. Thermodynamic Properties: Every system has certain characteristics such as Pressure, Volume, Temperature, Density, Internal Energy. Thermodynamics generally starts with several basic concepts and leads to different thermodynamics laws. branch of physics which is concerned with the relationship between other forms of energy and heat I Thermodynamic Systems and Properties. In science, thermodynamic properties are characteristics used to describe a physical system. However, if you hone in on the most important thermodynamic formulas and equations, get comfortable converting from one unit of physical measurement to another, and become familiar with the physical constants related to thermodynamics, youll be at the head of the class. Thermodynamics¶ Statistical mechanics grew out of an earlier field called thermodynamics, which was concerned with the thermal properties of liquids and ...
This is the lowest point on the Kelvin scale. When a system goes from an ordered state to a disordered state the entropy is increased. The second law of thermodynamics states that the total entropy of the universe or an isolated system never decreases. V= 1 V. The third law defines absolute zero and helps to explain that the entropy, or disorder, of the universe is heading towards a constant, nonzero value. Keywords: Nernst postulate, thermodynamics, entropy, quantum laws The third law of thermodynamics states that as the temperature approaches absolute zero in a system, the absolute entropy of the system approaches a constant value. The law of conservation of mass is also an equally fundamental concept in the theory of thermodynamics, but it is not generally included as a law of thermodynamics. This makes sense because the third law suggests a limit to the entropy value for different systems, which they approach as the temperature drops. It has had great influence on thermodynamics. THIRD LAW ...
TY - GEN. T1 - Energetics of alloy formation within statistical thermodynamics and electron theory. AU - Singh, R. N.. PY - 1997. Y1 - 1997. N2 - The deviation of the thermo-physical functions from the additive rule of mixing as a function of composition, temperature, and pressure is a key to an understanding of the energetics of alloy formation. The implications of the basic interactions of the metallic system i.e. electron-electron, ion-ion and electron-ion on formation energy are discussed within the first principle approach of the electronic theory. The pairwise interactions calculated from the first principle theory, coupled with pair distribution functions, provide a unique definition of the order energy which occurs as a free parameter in various thermodynamic models. The solution of the grand partition function within quasi-lattice approximation, and the hard sphere results modified for attractive tail interaction, are also considered to discuss the effects of entropic and enthalpic ...

The second law of thermodynamics can be interpreted as quantifying state transformations which are statistically unlikely so that they become effectively forbidden. The second law typically applies to systems composed of many particles interacting; Quantum thermodynamics resource theory is a formulation of thermodynamics in the regime where it can be applied to a small number of particles interacting with a heat bath. For processes which are cyclic or very close to cyclic, the second law for microscopic systems takes on a very different form than it does at the macroscopic scale, imposing not just one constraint on what state transformations are possible, but an entire family of constraints. These second laws are not only relevant for small systems, but also apply to individual macroscopic systems interacting via long-range interactions, which only satisfy the ordinary second law on average. By making precise the definition of thermal operations, the laws of thermodynamics take on a form with ...

In this paper, we combine the two universalisms of thermodynamics and dynamical systems theory to develop a dynamical system formalism for classical thermodynamics. Specifically, using a compartmental dynamical system energy flow model we develop a state-space dynamical system model that captures the key aspects of thermodynamics, including its fundamental laws. In addition, we establish the existence of a unique, continuously differentiable global entropy function for our dynamical system model, and using Lyapunov stability theory we show that the proposed thermodynamic model has finite-time convergent trajectories to Lyapunov stable equilibria determined by the system initial energies. Finally, using the system entropy, we establish the absence of Poincaré recurrence for our thermodynamic model and develop clear and rigorous connections between irreversibility, the second law of thermodynamics, and the entropic arrow of time.

The Third Law of Thermodynamics . ln This is because a system at zero temperature exists in its ground state, so that its entropy is determined only by the degeneracy of the ground state. Q No, seriously, how cold is it?

Third law of thermodynamics 1. The Nernst-Simon statement of the third law of thermodynamics concerns thermodynamic processes at a fixed, low temperature: The entropy change associated with any condensed system undergoing a reversible isothermal process approaches zero as the temperature at which it is performed approaches 0 K. Here a condensed system refers to liquids and solids. The Third Law of Thermodynamics. B Following thermodynamics
The First Law of the Thermodynamics is related to the conservation of energy, while the Second Law of Thermodynamics argue that some of the thermodynamics processes are impermissible and does not entirely follow the First Law of Thermodynamics.
The history of thermodynamics is fundamentally interwoven with the history of physics and history of chemistry and ultimately dates back to theories of heat in antiquity. The laws of thermodynamics are the result of progress made in this field over the nineteenth and early twentieth centuries. The first established thermodynamic principle, which eventually became the second law of thermodynamics, was formulated by Sadi Carnot in 1824 in his book Reflections on the Motive Power of Fire. By 1860, as formalized in the works of scientists such as Rudolf Clausius and William Thomson, what are now known as the first and second laws were established. Later, Nernsts theorem (or Nernsts postulate), which is now known as the third law, was formulated by Walther Nernst over the period 1906-12. While the numbering of the laws is universal today, various textbooks throughout the 20th century have numbered the laws differently. In some fields, the second law was considered to deal with the efficiency of ...
Thermodynamics is a part of science which is related with heat, temperature and energy. It is concerned with various forms of energy and its mutual conversion. The Thermodynamic behavior of different quantities or matter is controlled by 4 laws of thermodynamics. In this universe there is always a relation between any matter and energy. Thermodynamics is applicable in wide range of Science, Technology and Engineering world.

The development of thermodynamics in the second half of the 19th century has had a strong impact on both technology and natural philosophy. It is true that the steam engine for the conversion of heat into work existed before thermodynamics was developed as a branch of physics. However, the systematic theory improved the conversion process, and it succeeded in developing other processes essential to modern life, notably refrigeration and rectification. So, altogether thermodynamics has provided humanity with cheap energy, and cheap fuel, -- consequently with cheap, and abundant, and unspoiled food. Thus thermodynamics has made populations grow, and life expectancy increase beyond anything people could possibly have imagined 200 years ago. At the same time thermodynamics has uncovered the precarious balance between determinism and stochasticity which is essential to processes on earth, including life. The competition of those intentions is described by the doctrine of energy and entropy in ...
EN] Apple discs were impregnated with isotonic solutions of sucrose and trehalose with and without calcium addition and after air dried. In the vacuum impregnation experiments, the calcium and the replacement of sucrose by trehalose did not have significant effect on the final volumetric deformation of the samples. During air drying two stages of changes were considered. The first one lasted until the saturation of the intracellular liquid phase, and the second one from the saturation of the intracellular liquid phase until the end of the drying process. Mass transfer has been analysed applying nonlinear irreversible thermodynamics. Water flux, water chemical potential and tissue shrinkage have been taken into account in order to accurately describe the mass transfer phenomena during air drying. A precise definition of chemical potential allowed estimating the partial molar energy needed for breakages and the reversible and irreversible deformations of tissue structure coupled with mass transfer ...
R. Stephen Berry-. Thermodynamics is a beautiful illustration of how needs of very practical applications can lead to very basic, general concepts and relations, very much in contrast to the view that the practical and applied facets of a science are consequences of prior basic studies. Thermodynamics teaches us that ideas and concepts can flow in either direction, between the basic and the applied. It was the very practical challenge of finding the best, most efficient way to pump water out of tin mines in Cornwall and elsewhere that stimulated the thinking, notably the young French engineer Sadi Carnot, that led us to the very basic, general concepts, even laws of nature, that we call thermodynamics. Traditional, classical thermodynamics is deeply based on the concept that processes and machines have limits to how efficiently they can carry out their tasks, limits that minimize the wasteful losses that all real processes have. And traditional thermodynamics focuses on finding those limits ...

Polymer quantum systems are mechanical models quantized similarly as loop quantum gravity. It is actually in quantizing gravity that the polymer term holds proper as the quantum geometry excitations yield a reminiscent of a polymer material. In such an approach both non-singular cosmological models and a microscopic basis for the entropy of some black holes have arisen. Also important physical questions for these systems involve thermodynamics. With this motivation, in this work, we study the statistical thermodynamics of two one dimensional polymer quantum systems: an ensemble of oscillators that describe a solid and a bunch of non-interacting particles in a box, which thus form an ideal gas. We first study the spectra of these polymer systems. It turns out useful for the analysis to consider the length scale required by the quantization and which we shall refer to as polymer length. The dynamics of the polymer oscillator can be given the form of that for the standard quantum pendulum. ...

The present work aims to study the thermal stability and thermodynamics in the process of synthesizing 1, 3-dimethylurea. The HPLC spectrograms were used to study the impacts of reaction time and temperature on the thermal behaviour of the ammonolysis reaction system. Rate equation of the ammonolysis reaction can be summed up as c(t) = 1016.24*e-(t/47.9403) +16.1935. Thermal stability curve also can be determined. Experimental results revealed that the process of synthesizing 1, 3-dimethylurea was of pseudo-first-order reaction kinetics and k value was 0.0163 min-1. Thermodynamics results indicated that enthalpy was -1.92 kJ/mol, Gibbs free energy was -8.51 J/mol, and entropy was 15.96 J/mol*K. The reaction was an exothermic, spontaneous and entropy increasing process. Based on thermal stability and thermodynamics study, synthesis of 1, 3-dimethylurea was unfavourable at higher temperature as well as long reaction time ...
The parametrization and testing of the OPLS all-atom force field for organic molecules and peptides are described. Parameters for both torsional and nonbonded energetics have been derived, while the bond stretching and angle bending parameters have been adopted mostly from the AMBER all-atom force field. The torsional parameters were determined by fitting to rotational energy profiles obtained from ab initio molecular orbital calculations at the RHF/6-31G*//RHF/6-31G* level for more than 50 organic molecules and ions. The quality of the fits was high with average errors for conformational energies of less than 0.2 kcal/mol. The force-field results for molecular structures are also demonstrated to closely match the ab initio predictions. The nonbonded parameters were developed in conjunction with Monte Carlo statistical mechanics simulations by computing thermodynamic and structural properties for 34 pure organic liquids including alkanes, alkenes, alcohols, ethers, acetals, thiols, sulfides, disulfides,

The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while. Due to the force of gravity, density and pressure do not even out vertically. Density and pressure on the bottom will be more than at the top. Entropy is a measure of spread of matter and energy to everywhere they have access. The most common wording for the second law of thermodynamics is essentially due to Rudolf Clausius: ...

The thermodynamics of a monoclonal antibody (mAb)-peptide interaction have been characterized by isothermal titration microcalorimetry. GCC:B10 mAb, generated against human guanylyl cyclase C, a membrane-associated receptor and a potential marker for metastatic colon cancer, recognizes the cognate peptide epitope HIPPENIFPLE and its two contiguous mimotopes, HIPPEN and ENIFPLE, specifically and reversibly. The exothermic binding reactions between 6.4 and 42 degreeC are driven by dominant favorable enthalpic contributions between 20 and 42 degreeC, with a large negative heat capacity (DELTACp) of -421 +- 27 cal mol-1 K-1. The unfavorable negative value of entropy (DELTASb0) at 25 degreeC, an unusual feature among protein-protein interactions, becomes a positive one below an inversion temperature of 20.5 degreeC. Enthalpy-entropy compensation due to solvent reorganization accounts for an essentially unchanged free energy of interaction (DELTADELTAGb0 simeq 0). The role of water molecules in the ...
Quantum thermodynamics addresses the emergence of thermodynamic laws from quantum mechanics. The viewpoint advocated is based on the intimate connection of quantum thermodynamics with the theory of open quantum systems. Quantum mechanics inserts dynamics into thermodynamics, giving a sound foundation to finite-time-thermodynamics. The emergence of the 0-law, I-law, II-law and III-law of thermodynamics from quantum considerations is presented. The emphasis is on consistency between the two theories, which address the same subject from different foundations. We claim that inconsistency is the result of faulty analysis, pointing to flaws in approximations.
The second law of thermodynamics is considered one of the central laws of science, engineering and technology. For over a century it has been assumed to be inviolable by the scientific community. Over the last 10-20 years, however, more than two dozen challenges to it have appeared in the physical literature - more than during any other period in its 150-year history. The number and variety of these represent a cogent threat to its absolute status. This is the first book to document and critique these modern challenges. Written by two leading exponents of this rapidly emerging field, it covers the theoretical and experimental aspects of principal challenges. In addition, unresolved foundational issues concerning entropy and the second law are explored. This book should be of interest to anyone whose work or research is touched by the second law ...
A general review on macrocyclic ligands with particular emphasis to dibenzocryptand 222 and dibenzo 18 crown 6 is given in the first part of the thesis (Chapter 1). This is followed by an exhaustive literature survey on the stability constants (hence free energies of complexing), enthalpies and entropies of metal cations with cryptands (dibenzocryptand 222, benzocryptand 222, cryptand 222) and crown ethers (dibenzo 18 crown 6, benzo 18 crown 6, 18 crown 6) in water and in non-aqueous solvents at 298.15 (Chapter 2). The experimental part (Chapter 3) also includes a detailed description of the principals involved in calorimetry as well as the methods used for the calculation of reaction enthalpies. Stability constant data for alkali-metal and silver cations with dibenzocryptand 222 in five dipolar aprotic solvents (N,N dimethyl-formamide, dimethylsulphoxide, acetonitrile, propylene carbonate and nitromethane) at 298.15 K are reported. These data are used to calculate the standard free energies of ...
Integral membrane proteins, including G protein-coupled receptors (GPCR) and ion channels, mediate diverse biological functions that are crucial to all aspects of life. The knowledge of the molecular mechanisms, and in particular, the thermodynamic basis of the binding interactions of the extracellular ligands and intracellular effector proteins is essential to understand the workings of these remarkable nanomachines. In this review, we describe how isothermal titration calorimetry (ITC) can be effectively used to gain valuable insights into the thermodynamic signatures (enthalpy, entropy, affinity, and stoichiometry), which would be most useful for drug discovery studies, considering that more than 30% of the current drugs target membrane proteins. This article is part of a Special Issue entitled: Structural and biophysical characterisation of membrane protein-ligand binding.

The Second law of thermodynamics states that the state of entropy of the universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.. Why is it that when you leave an ice cube at room temperature, it begins to melt? Why do we get older and never younger? And, why is it whenever rooms are cleaned, they become messy again in the future? Certain things happen in one direction and not the other, this is called the arrow of time and it encompasses every area of science. The thermodynamic arrow of time (entropy) is the measurement of disorder within a system, the change of entropy suggests that time itself is asymmetric with respect to order of an isolated system, a system will become more disordered, as time increases.. Derivation: To understand why entropy increases and decreases, it is important to recognize that two changes in entropy have to consider at all times. The entropy change of the ...
Jülich, 26 November 2014 - Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast. Their findings have been published in Nature Communications and could help to improve fundamental simulation methods for chemistry, physics, biology, and materials science.

Physical processes that govern the growth kinetics of carbon clusters at high pressure and high temperature are: (a) thermodynamics and structural |i|sp|/i|?-to-|i|sp|/i|? bonding) changes and (b) cluster diffusion. Our study on item (a) deals with |i|ab initio|/i| and semi-empirical quantum mechanical calculations to examine effects of cluster size on the relative stability of graphite and diamond clusters and the energy barrier between the two. We have also made molecular dynamics simulations using the Brenner bond order potential. Kesults show that the melting line of diamond based on the Brenner potential is reasonable and that the liquid structure changes from mostly |i|sp|/i|-bonded carbon chains to mostly |i|sp|/i|?-bonding over a relatively narrow density interval. Our study on item (b) uses the time-dependent clustor size distribution function obtained from the relevant Smoluchowski equations. The resulting surface contribution to the Gibbs free energy of carbon clusters was implemented in a

And the fundamental equations. And how powerful the fundamental equations were in being able to calculate anything from pressure, volume, temperature data. And you saw that the Gibbs free energy was especially important for everyday sort of processes. Because of the constant pressure constraint. And the fact that the intrinsic variables are pressure and temperature. Well, it turns out that the Gibbs free energy is even more important than that. And this is something that it took me a while to learn. I had to take thermodynamics many times to really appreciate how important that was. Even when I was doing research, at the beginning, I was a theorist, ...
See also Kirchhoffs laws (disambiguation) for other laws named after Gustav Kirchhoff. In heat transfer, Kirchhoffs law of thermal radiation refers to wavelength-specific radiative emission and absorption by a material body in thermodynamic equilibrium, including radiative exchange equilibrium. A body at temperature T radiates electromagnetic energy. A perfect black body in thermodynamic equilibrium absorbs all light that strikes it, and radiates energy according to a unique law of radiative emissive power for temperature T, universal for all perfect black bodies. Kirchhoffs law states that: For a body of any arbitrary material emitting and absorbing thermal electromagnetic radiation at every wavelength in thermodynamic equilibrium, the ratio of its emissive power to its dimensionless coefficient of absorption is equal to a universal function only of radiative wavelength and temperature. That universal function describes the perfect black-body emissive power. Here, the dimensionless ...

physical chemistry - Statistical Thermodynamics - Thermodynamics provides chemists with the power to calculate, from thermochemical data alone, how far any chemical reaction will proceed before reaching equilibrium. Theoretical chemists would like to make such calculations without thermochemical data, however, using only the quantum mechanical descriptions of isolated molecules, but thermodynamics is based on the bulk properties of matter and reflects averages of very large numbers of molecules.Quantum mechanics, on the other hand, provides information only about the quantized energy…

So there are two things that were important. We learned that the chemical potential for a species is the Gibbs free energy for that species divided by the number of moles, this is Gibbs free energy per mole. We learned that the pressure dependence of the Gibbs free energy gives you the pressure dependence for the chemical potential. That its equal to the chemical potential at one bar for an ideal gas plus RT log p. We also learned that a species will want to go to minimize its chemical potential, and we saw that for the cell bursting in salt, in distilled water. Or an ice cube melting at a temperature greater than 0 degrees. And what we ...

Proteins however exhibit a large degree of motion over a broad range of timescales and magnitudes and this is defined thermodynamically by the enzyme free energy landscape (FEL). The role and importance of enzyme motion is extremely contentious. Much of the challenge is in the experimental detection of so called conformational sampling involved in enzyme turnover. Herein we apply combined pressure and ...

Also paramount is to understand the relationship between thermodynamics and kinetics, something that again benefits from studying reactions under thermodynamic and kinetic control and things like the Curtin-Hammet principle in classical physical organic chemistry. Its crucial to know the difference between thermodynamic and kinetic stability, especially when one is dealing with small molecule and protein conformations. Finally, its enormously valuable to have a feel for a few key numbers, foremost among which may be the relationship between equilibrium constant and free energy; knowing this tells you for instance that it takes only a difference of 1.8 kcal/mol of free energy between two conformers to almost completely shift the conformational equilibrium on to the side of the more stable one. And when that difference is 3 kcal/mol, the higher-energy conformation is all gone, well beyond the detection limits of techniques like NMR. Speaking of which, a good understanding of thermodynamics also ...

The Second Law of Thermodynamics is an insurmountable obstacle to the spontaneous formation of highly complex organic molecules. Evolutionists cannot explain away the problem by appealing to the earth being an open system. Inputting free energy into a system speeds up the rate of entropy increase.
The second law of thermodynamics (the entropy law or law of entropy) was formulated in the middle of the last century by Clausius and Thomson following Carnot s earlier observation that, like the fall...
Accurate estimation of protein-carbohydrate binding energies using computational methods is a challenging task. Here we report the use of expanded ensemble molecular dynamics (EEMD) simulation with double decoupling for estimation of binding energies of hevein, a plant lectin with its monosaccharide and disaccharide ligands GlcNAc and (GlcNAc)(2), respectively. In addition to the binding energies, enthalpy and entropy components of the binding energy are also calculated. The estimated binding energies for the hevein-carbohydrate interactions are within the range of +/- 0.5 kcal of the previously reported experimental binding data. For comparison, binding energies were also estimated using thermodynamic integration, molecular dynamics end point calculations (MM/GBSA) and the expanded ensemble methodology is seen to be more accurate. To our knowledge, the method of EEMD simulations has not been previously reported for estimating biomolecular binding energies.. ...

In the field of biophysics, the study of the thermodynamic characteristics of biomolecules, such as DNA, RNA or proteins, allows us to understand more about the building blocks of life. The thermodynamic characterization of the biomolecule gives us clues as to their functions and capabilities inside every living organism. The thermodynamic characterization of nucleic acids describes how temperature affects the stability and the structure of double stranded DNA. The melting temperature of DNA (T(M)) is defined as the temperature at which half of the DNA strands in a bulk solution experiment are in the double stranded DNA (dsDNA) or random coil configuration and half of the DNA are in the single-stranded DNA (ssDNA) configuration. Using T(M), it has been possible to experimentally determine the thermodynamic parameters of Delta-G, Delta-H and Delta-S. Viceversa, when the thermodynamic parameters of a given nucleic acid sequence are known, the TM can be predicted. This effect has important applications
Target-guided synthesis is an approach to drug discovery that uses the biological target as a template to direct synthesis of its own best inhibitors from small molecule fragments. The process bridges the gap between chemical synthesis of drug candidates and their biological binding assay, merging the two operations into a single process whereby the active site or a binding pocket within the structure of the biological target directly controls the assembly of the best inhibitor in situ. Two different approaches to target-guided synthesis, the thermodynamic approach, making use of reversible reactions, and the kinetic approach, which uses an irreversible reaction, have been employed to discover novel, isoform selective inhibitors of the glutathione transferase (GST) enzyme family - possible drug targets in cancer and parasitic disease treatments. The thermodynamic approach described in this thesis uses the aniline-catalysed reversible acyl hydrazone formation reaction to create a dynamic covalent ...
