A novel push-pull Diels-Alder diene: reactions of 4-alkoxy- or 4-phenylsulfenyl-5-chalcogene-substituted 1-phenylpenta-2,4-dien-1-one with electron-deficient dienophiles. (1/16)

5-(phenylselenenyl)- and 5-(phenylsulfenyl)-4-ethoxy-1-phenyl-2,4-pentadien-1-ones (2) and (3) underwent [4+2] cycloaddition with N-methyl and N-phenylmaleimides and successive isomerization to give the 7-benzoyl-3a,4,5,7a-tetrahydro-1H-isoindole-1,3(2H)-diones 5, 8 and 9 in good yields. The 4-ethoxy group on the 2,4-pentadien-1-one was found to be effective to facilitate the cycloaddition with dienophiles. We also performed other [4+2] cycloadditions of 2,4-pentadien-1-ones with DMAD or naphthoquinone.  (+info)

Redox catalysts as sensitisers towards oxidative stress. (2/16)

The predominance of oxidative stress in many tumour cell environments provides a means to selectively target these cells via protein oxidation. The zinc fingers of transcription factors utilise cysteine thiols for structural zinc coordination. Redox control of DNA binding regulates transcription and therefore the overall rates of proliferation, apoptosis and necrosis in the carcinoma. We report here the adverse effects of glutathione peroxidase (GPx) mimics towards zinc finger motifs and PC12 cell survival. Nanomolar catalyst concentrations facilitated H2O2-induced oxidation of an Sp1 transcription factor fragment. In PC12 cells GPx catalysis triggered a significant increase in cell death, correlating with severity of oxidative stress. As a consequence, we conclude that GPx mimics are potential chemotherapeutic agents.  (+info)

Synthesis and properties of benzo[a]phenoxazinium chalcogen analogues as novel broad-spectrum antimicrobial photosensitizers. (3/16)

The goal of this investigation was to develop improved photosensitizers for use as antimicrobial drugs in photodynamic therapy of localized infections. Replacement of the oxygen atom in 5-(ethylamino)-9-diethylaminobenzo[a]phenoxazinium chloride (1) with sulfur and selenium afforded thiazinium and selenazinium analogues 2 and 3, respectively. All three dyes are water soluble, lipophilic, and red light absorbers. The relative photodynamic activities of the chalcogen series were evaluated against a panel of prototypical pathogenic microorganisms: the Gram-positive Enterococcus faecalis, the Gram-negative Escherichia coli, and the fungus Candida albicans. Selenium dye 3 was highly effective as a broad-spectrum antimicrobial photosensitizer with fluences of 4-32 J/cm2 killing 2-5 more logs of all cell types than sulfur dye 2, which was slightly more effective than oxygen analogue 1. These data, taken with the findings of uptake and retention studies, suggest that the superior activity of selenium derivative 3 can be attributed to its much higher triplet quantum yield.  (+info)

Highly strained heterocycles constructed from Boron-Boron multiple bonds and heavy chalcogens : Sussex Research OnlineHighly strained heterocycles constructed from Boron-Boron multiple bonds and heavy chalcogens : Sussex Research Online
The reactions of a diborene with elemental selenium or tellurium are shown to afford a diboraselenirane or diboratellurirane, respectively. These reactions are reminiscent of the sequestration of sub-valent oxygen and nitrogen in the formation of oxiranes and aziridines; however, such reactivity is not known between alkenes and the heavy chalcogens. While carbon is too electronegative to facilitate the reduction of elements of lower relative electronegativity, this is overcome by the highly reducing nature of the double bond in diborenes. The capacity of multiple bonds between boron to donate electron density is highlighted in a reaction where diboryne is shown to behave as nucleophile, attacking diarylditellurides in the formation of a diboratellurenium cations with aryltelluride anions.. ...

The Group II-IV nitride semiconductors are emerging as promising alternatives to III-nitrides in ultraviolet LED applications. These materials have wurtzite-derived orthorhombic crystal structures and can be obtained by substituting pairs of Group III atoms in a III-nitride for a single Group II atom and a single Group IV atom. Here we will focus on MgSiN$_{2}$, which is the equivalent II-IV nitride to wurtzite AlN. A detailed comparison of the properties obtained by first principles calculations and experiment of these two systems will be performed. It will be shown that MgSiN$_{2}$ has a large indirect band gap of similar size to the direct band gap of AlN, while having a crystal size which is intermediate between AlN and GaN.\footnote{J. B.

Interestingly, a recent study by Ohno et al. (2014) demonstrated that deletion of SNPH is counterproductive to axonal survival in acute demyelination. They proposed that SNPH serves an adaptive function by creating large-volume, stationary mitochondria to better fit the energy demands of acutely demyelinated axons and help them survive. In contrast, our studies demonstrate that SNPH deletion in chronic dysmyelination (Shi) dramatically prolongs survival and prevents neural damage. It is clear that these two studies address different phases of MS. We propose a biphasic model for the functional impact of SNPH during MS: mitochondrial anchoring by SNPH is adaptive in the early phase (Fig. 12A) and maladaptive in the late phase (Fig. 12B).. During the early phase of acute myelin loss, as in the study of Ohno et al. (2014), SNPH is modestly elevated to arrest motile mitochondria to meet metabolic demands to keep axons alive (Fig. 12A). Deletion of SNPH at this stage is detrimental to axons. However, ...

Hybrid double perovskites have recently gained a vast amount of attention in the research area of photovoltaics as lead-free alternatives to the ground-breaking parent material [CH3NH3]PbI3.1 In double perovskites with the general formula A2BBX6, two Pb2+ cations are effectively replaced with a monovalent B and a trivalent B cation. Among the many fascinating properties of hybrid inorganic-organic perovskites, it is arguably the combination of strong light absorbance and long carrier lifetimes that make them so interesting for photovoltaic applications and light-emission devices. Recent experimental and theoretical studies on [CH3NH3]PbI3 revealed a direct-indirect character of the bandgap, i.e. [CH3NH3]PbI3 exhibits a direct band gap which is only approximately 47-60 meV higher in energy than the indirect band gap. Presumably, this is the origin of the paradox of strong absorption and long charge carrier lifetimes. When now turning our attention to lead free double perovskites, examples ...

In the current study, we sought to identify proteins regulating mitochondrial docking in axons. By applying a proteomic approach and cell biological assays combined with time-lapse imaging in live neurons, we reveal that LC8 enhances the SNPH-mediated mitochondrial docking efficiency through modulating the dynamic interaction between the docking receptor and axonal cytoskeleton. Four lines of evidence support this view. First, SNPH selectively interacted with LC8 via its seven-residue LC8-binding motif (ERAIQTD). The SNPH-LC8 complex was detected in vivo by coimmunoprecipitation of brain homogenates from snph wild-type but not snph (−/−) mice; the interaction occurred independently of the dynein motor complex. Second, SNPH recruited LC8 to axonal mitochondria via its LC8-binding motif. Deleting this motif reduced the efficiency of SNPH in docking axonal mitochondria. Furthermore, elevated LC8 expression inhibited the mobility of axonal mitochondria through endogenous SNPH. LC8 ...

The hidden side of sulfurThe hidden side of sulfur
The team wanted to know whether this hole could act as a vacuum cleaner, like hydrogen, if it were placed in contact with a substrate. If this were the case, sulfur could be used as a catalyst, causing molecules to transform themselves. This somewhat unorthodox bond, known as a chalcogen bond, would thus replace the conventional hydrogen bond.. As Professor Matile further explains: To test our hypothesis, we created and tested a series of molecular structures using chalcogen bonds of gradually increasing strength. We noticed that they not only work, but that they increase the speed of the transformation by more than a thousand times, as when there is no catalyst. Additionally, we achieved a degree of precision that is impossible with hydrogen bonds. In fact, hydrogens entire surface is electron poor.. Thus, when it is playing the role of catalyst, the entire atom can come into contact with the substrate and suck up negative charges all over. However, with sulfur, only a small area can act ...

JCI - Syntaphilin controls a mitochondrial rheostat for proliferation-motility decisions in cancerJCI - Syntaphilin controls a mitochondrial rheostat for proliferation-motility decisions in cancer
Tumors adapt to an unfavorable microenvironment by controlling the balance between cell proliferation and cell motility, but the regulators of this process are largely unknown. Here, we show that an alternatively spliced isoform of syntaphilin (SNPH), a cytoskeletal regulator of mitochondrial movements in neurons, is directed to mitochondria of tumor cells. Mitochondrial SNPH buffers oxidative stress and maintains complex II-dependent bioenergetics, sustaining local tumor growth while restricting mitochondrial redistribution to the cortical cytoskeleton and tumor cell motility. Conversely, introduction of stress stimuli to the microenvironment, including hypoxia, acutely lowered SNPH levels, resulting in bioenergetics defects and increased superoxide production. In turn, this suppressed tumor cell proliferation but increased tumor cell invasion via greater mitochondrial trafficking to the cortical cytoskeleton. Loss of SNPH or expression of an SNPH mutant lacking the mitochondrial localization ...

Try telling that to grape growers in Northern California, who repeatedly call on Mondavi to seek out water for their industrial-size wells. Mysterious ability Hes a bona fide water witch - someone who can find groundwater without the use of science. Theres no scientific evidence to support the practice - in fact, most science experiments to determine its authenticity have concluded that dowsers find water no better than the rate of chance.

The Hippie Housewife: February 2011The Hippie Housewife: February 2011
With my oldest, I found the convenience of babywearing to be indispensable. In his early weeks, he often napped in a carrier, preferring the warmth and movement over a flat bed. It also provided him with a familiar place to nap while out of the house. When teething hit, it hit hard, and many days I would walk around the house with him tucked contentedly in a wrap and a book in my hand. During each evenings witching hour, I would wrap him up snuggly and go for a long walk through our favourite trail. With him secure on my back, I could browse our local farmers market without the inconvenience of a stroller. During stages when he wanted to be held more often than not, it allowed me to get housework done and food on the table while meeting his needs at the same time ...

Hydrogen chalcogenide - WikipediaHydrogen chalcogenide - Wikipedia
Hydrogen chalcogenides (also chalcogen hydrides or hydrogen chalcides) are binary compounds of hydrogen with chalcogen atoms (elements of group 16: oxygen, sulfur, selenium, tellurium, and polonium). Water, the first chemical compound in this series, contains one oxygen atom and two hydrogen atoms, and is the most common compound on the Earths surface. The most important series, including water, has the chemical formula H2X, with X representing any chalcogen. They are therefore triatomic. They take on a bent structure and as such are polar molecules. Water is an essential compound to life on Earth today, covering 70.9% of the planets surface. The other hydrogen chalcogenides are usually extremely toxic, and have strong unpleasant scents usually resembling rotting eggs or vegetables. Hydrogen sulfide is a common product of decomposition in oxygen-poor environments and as such is one chemical responsible for the smell of flatulence. It is also a volcanic gas. Despite its toxicity, the human body ...

Oxygen - New World EncyclopediaOxygen - New World Encyclopedia
Oxygen is classified as a nonmetal. In the periodic table, it is located at the top of group 16 (formerly group 6A), which is a family of elements called the chalcogens or the oxygen family. In addition, it lies between nitrogen and fluorine in period 2.. At ordinary temperatures and pressures, free oxygen (unbound to any other element) is a colorless, odorless, tasteless gas that makes up about 21% (by volume) of air. Ordinarily, each molecule of oxygen gas consists of two oxygen atoms bound to each other, so the molecular formula is written as O2.. This molecular oxygen (O2) is essential for the human bodys metabolic processes, which sustain our lives. The human body cannot store oxygen for later use as it does with food. If the body is deprived of oxygen for more than a few minutes, unconsciousness results. The bodys tissues and organs (notably the heart and brain) are damaged if deprived of oxygen for much longer than four minutes.. Gaseous oxygen becomes a liquid at temperatures below ...

The Chemical Reactivity of elements in the p-block increments as we move towards right in a period. Be that as it may, as we move down in a group the chemical reactivity of elements declines down the group.. i) Reactivity of Noble Gases: All the orbitals of the noble gasses are totally filled by electrons and it is exceptionally hard to break their stability in any way whether it is the removal of electrons or addition of electrons. Hence the noble gasses show low compound reactivity. In light of their low reactivity noble gasses, are regularly utilized when a nonreactive climate is required, for example, in welding.. Going before the noble gas family there are two chemically essential groups of non-metals. They are the halogens (Group 17) and the chalcogens (Group 16). These two groups of elements have high electron gain enthalpies and can promptly include one to two electrons framing an anion to achieve the steady noble gas configuration in this way indicating great chemical ...

organic chemistry - What is the effect of substituting oxygen with sulfur in drug molecules? - Chemistry Stack Exchangeorganic chemistry - What is the effect of substituting oxygen with sulfur in drug molecules? - Chemistry Stack Exchange
In asking this question - Why do chalcogens (Group VI) stink so badly? - I received a couple answers and comments along the lines of its not quite so simple. The same would generally apply here; there isnt one change in behavior, or even a finite set of behavioral changes, that could be predicted by an oxygen-to-sulfur exchange.. Just as a basic example, compare methanol ($\ce{CH_3(OH)}$) to methyl mercaptan, ($\ce{CH_3(SH)}$). Methanol is a colorless liquid at RT with a sweetish odor. Methyl mercaptan, with a higher molecular mass due to the sulfur switch, is nevertheless a gas at RT and smells like rotting cabbage. Methanol metabolizes into formic acid and formaldehyde which in sufficient doses causes nerve damage, specifically to the optic nerve. Methyl mercaptan is pretty much its own metabolite; while also toxic in sufficient doses, its readily filtered out by the liver and kidneys, as its produced by bacterial breakdown of many of the foods we eat (especially highly-fibrous ...

α-CuIn1-xGaxSe2 based materials with direct band gap and high absorption coefficient are promising materials for high efficiency hetero-junction solar cells. CIGS champion cell efficiency (19.9%, AM1.5G) is very close to polycrystalline silicon (20.3%, AM1.5G). A reduction in the price of CIGS module is required for competing with well matured silicon technology. Price reduction can be achieved by decreasing the manufacturing cost and by increasing module efficiency. Manufacturing cost is mostly dominated by capital cost. Device properties of CIGS are strongly dependent on doping, defect chemistry and structure which in turn are dependent on growth conditions. The complex chemistry of CIGS is not fully understood to optimize and scale processes. Control of the absorber grain size, structural quality, texture, composition profile in the growth direction is important to achieving reliable device performance. In the present work, CIS and CGS nanoparticles were prepared by a liquid phase synthesis ...

Multi-junction Photovoltaics - Engineering LibreTextsMulti-junction Photovoltaics - Engineering LibreTexts
Light that has a energy equal to or higher than Eg can excite the electrons across the junction; however, light that has lower energy, will pass through. Therefore, a material with a low band gap energy can utilize more light in the electromagnetic spectrum. Consequently, a photon with higher energy than Eg will not create a larger voltage than one with equal energy to the band gap. The size of the band gap dictates the energy generated by exciting an electron. A smaller band gap will result in lower energy; therefore, there is a balance between having a small band gap that will utilize many photons and having a large band gap that will utilize fewer photons, yet generate more energy from them. The optimum band gap is at approximately 1.4 eV and the theoretical limit of a single junction cell with this Eg is approximately 31% [3]. The actual efficiency and theoretical efficiency are greatly improved on with the addition of multiple pn junctions and therefore multiple band gaps. With various band ...

Correlated Electrons in Transition-Metal Compounds: New ChallengesCorrelated Electrons in Transition-Metal Compounds: New Challenges
Half-metals are rather unusual and promising materials. The Fermi surface of a half-metal is completely spin-polarized. Namely, electronic states with only one spin projection value reach the Fermi energy. States with the other spin projection are pushed away from the Fermi level. This makes half-metals useful for spintronics. Typically, half-metallicity arises in strongly correlated electron systems, or when localized magnetic moments are present. Here, we demonstrate that doping a density-wave insulator even in the weak-coupling limit may stabilize new types of half-metallic states, such as spin-valley half-metal and charge-density wave (CDW) half-metal [1]. Our analysis is based on a simple model Hamiltonia describing charge carriers belonging to two bands: electron band $a$ and hole band $b$. Both bands have the parabolic dispersion law and spherical Fermi surface pockets (or valleys). When the Fermi surface valleys nest well (that is, the Fermi momentum of electrons $a$ equals to the Fermi ...

Graded band gap GaInNAs solar cells (Journal Article) | SciTech ConnectGraded band gap GaInNAs solar cells (Journal Article) | SciTech Connect
Dilute nitride GaInN(Sb)As with a band gap (E{sub g}) of 1.0 eV is a promising material for the integration in next generation multijunction solar cells. We have investigated the effect of a compositionally graded GaInNAs absorber layer on the spectral response of a GaInNAs sub cell. We produced band gap gradings (ΔE{sub g}) of up to 39 meV across a 1 μm thick GaInNAs layer. Thereby, the external quantum efficiency-compared to reference cells-was increased due to the improved extraction of photo-generated carriers from 34.0% to 36.7% for the wavelength range from 900 nm to 1150 nm. However, this device figure improvement is accompanied by a small decrease in the open circuit voltage of about 20 mV and the shift of the absorption edge to shorter wavelengths. ...

Band gap engineering in amorphous Al[sub x]Ga[sub 1-x]N: Experiment and ab initio calculationsBand gap engineering in amorphous Al[sub x]Ga[sub 1-x]N: Experiment and ab initio calculations
Amorphous alloys of aluminum nitride and gallium nitride deposited at 100 K at compositions ranging from pure AlN to pure GaN with optical band gaps which vary linearly with composition from 3.27 eV (a-GaN) to 5.95 eV (a-AlN) have been synthesized. Ab initio molecular dynamics calculations for these alloys reproduce the band gap versus composition data and give specific information on the electronic localization of the band tail states. There are no midgap states in amorphous Al[sub x]Ga[sub 1-x]N alloys. The calculated models have mixed four-fold and three-fold coordination and have no wrong (homopolar nuclear) bonds, demonstrating the strong ionicity in amorphous Al[sub x]Ga[sub 1-x]N alloys. It has been found that the valence band tail states are mostly localized on the three-fold coordinated N sites while the conduction band tail states are mostly localized on the three-fold coordinated Ga or Al sites. © 2000 American Institute of Physics ...

She also mentioned that the supplement was useful for women going through menopause who were having problems with sleep.. There is nothing worse than waking up in the night and not being able to get back to sleep. You lie there tossing and turning, probably stressing yourself into a few night sweats in the process. Of course, its at this point when your mind seems to switch into major alert mode and all those things youve got to do start forming into wonderful lists in your head.. I used to call it the Witching Hour; it would start around 01:50 and could last up to three hours at its worst. Falling asleep when you know the alarm clock is going to go off in around 2 hours is really the worst, especially when it happens night after night. You cant function as a human being, let alone an employee, mother or ...

CHAPTER THIRTEEN. The night is made up of so many colours. Not only colours… textures too. There is the velvety softness of indigo, the sort you long to rub your face against and bury your sadness in, hoping that it will muffle the emotion as it would deaden the sound of church bells. Then there is the smooth sensuality of pure blackness, like treacle pouring over your body and caressing it as it coats and covers. Twilight is silent; dark and lightless, silhouetting all objects and removing dimensions from everything it touches; it whispers and shrouds, preparing for the witching hours. Dawn seeps through, watery and grey, killing the night and bearing with it a feeling of death, light fingers revealing the greyness of its body in its state of eternal slumber.. Tomorrow, the dawn will light upon the body of Thomas, my friend whom I must kill. My tears shatter the dream of nights which shimmers so slightly in a puddle below the seat of the swing on which I sit. The fragments are like the ...

Band gap narrowing in zinc oxide-based semiconductor thin films (Journal Article) | SciTech ConnectBand gap narrowing in zinc oxide-based semiconductor thin films (Journal Article) | SciTech Connect
A simple expression is proposed for the band gap narrowing (or shrinkage) in semiconductors using optical absorption measurements of spin coated 1 at. % Ga-doped ZnO (with additional 0-1.5 at. % zinc species) thin films as ΔE{sub BGN} = Bn{sup 1/3} [1 − (n{sub c}/n){sup 1/3}], where B is the fitting parameter, n is carrier concentration, and n{sub c} is the critical density required for shrinkage onset. Its uniqueness lies in not only describing variation of ΔE{sub BGN} correctly but also allowing deduction of n{sub c} automatically for several M-doped ZnO (M: Ga, Al, In, B, Mo) systems. The physical significance of the term [1 − (n{sub c}/n){sup 1/3}] is discussed in terms of carrier separation. ...

Post-transition metalPost-transition metal
Aluminium sometimes is[77] or is not[3] counted as a post-transition metal. It has a well shielded [Ne] noble gas core rather than the less well shielded [Ar]3d10, [Kr]4d10 or [Xe]4f145d10 core of the post-transition metals. The small radius of the aluminium ion combined with its high charge make it a strongly polarizing species, prone to covalency.[78] Aluminium in pure form is a soft metal (MH 3.0) with low mechanical strength.[79] It has a close-packed structure (BCN 12) showing some evidence of partially directional bonding.[80][n 10] It has a low melting point and a high thermal conductivity. Its strength is halved at 200 °C, and for many of its alloys is minimal at 300 °C.[82] The latter three properties of aluminium limit its use to situations where fire protection is not required,[83] or necessitate the provision of increased fire protection.[84][n 11] It bonds covalently in most of its compounds;[88] has an amphoteric oxide; and can form anionic aluminates.[60] Aluminium forms Zintl ...
