Structure refinement of high-resolution X-ray powder diffraction data of the title compound gave the composition Li(1.865)CoP(2)O(7), which is also verified by the ICP measurement. Two Co sites exist in the structure: one is a CoO(5) square pyramid and the other is a CoO(6) octa-hedron. They share edges and are furthe…
The time scales of crystallization of two model liquids, an atomic liquid and a molecular liquid of bent trimers originally introduced as a model of the glass the former o-terphenyl, are determined using molecular dynamics simulations. The molecular liquid is found to have a minimum crystallization time, on supercooli…
Malic enzymes have high cofactor selectivity. An isoform-specific distribution of residues 314, 346, 347 and 362 implies that they may play key roles in determining the cofactor specificity. Currently, Glu314, Ser346, Lys347 and Lys362 in human c-NADP-ME were changed to the corresponding residues of human m-NAD(P)-ME…
The new Ca2CoTaO6 double perovskite has been synthesized by a conventional solid state reaction and its unit cell parameters determined by X-ray powder diffractometry. It crystallizes in the monoclinic space group P2(1)/n. The unit cell parameters are: a = 5.507(2) Å; b = 5.564(3) Å; c = 7.798(3) Å; β = 89.99(4)° and…
The electronic and charge transport properties of a series of methylchalcogeno-substituted acene derivatives are investigated via quantum chemical calculations. To gain a better understanding of the role of methylchalcogeno substitution, the results for bis(methylchalcogeno)anthracene and bis(methylthio)pentacene are…
The synergistic effect of air pollution, brown clouds and greenhouse gasses is deleterious to human health and industrial products. The use of toxic inhibitors, chemicals in water treatment plants, and anti-fouling agents in desalination plants has contributed to the greenhouse effect. Conventional anti-corrosion tech…
The left-handed behavior of a photonic-crystal flat lens with a graded index in a honeycomb lattice is proposed and theoretically studied. The performance of the flat superlens imaging of this structure has been demonstrated by finite-difference time-domain simulations. The full width at half-maximum of the image decr…
UV optical properties of thin film layers of compound and mixed oxide materials deposited by different processes are presented. Japan Electron Optics Laboratory plasma ion assisted deposition (JEOL PIAD), electron beam with and without IAD, and pulsed DC magnetron sputtering were used. Comparisons are made with publis…
Sec14 is the major phosphatidylinositol (PtdIns)/phosphatidylcholine (PtdCho) transfer protein in the yeast Saccharomyces cerevisiae and is the founding member of the Sec14 protein superfamily. Recent functional data suggest that Sec14 functions as a nanoreactor for PtdCho-regulated presentation of PtdIns to PtdIns ki…
The template-assisted electrodeposition technique has been employed to synthesize highly ordered: uniformly dense, well-aligned, parallel and homogeneous copper nanowires. Their morphological studies have been carried out using the scanning electron microscopy and transmission electron microscopy. The X-ray diffractio…
We present direct laser writing of channels in chalcogenide glass under light filamentation conditions. Because of the intrinsic properties of the filament, the positive refractive index profile of the channels exhibits a cylindrical symmetry of high quality. The role of the repetition rate is also investigated. It is…
This paper reports on the synthesis and the thermal and optical properties of photochromic low-molecular-weight compounds, especially with respect to the formation of holographic volume gratings in the pure materials and in binary blends with polystyrene. Its aim is to provide a basic understanding of the holographic…
Electrostatic properties of two-dimensional nanosystems can be completely described by their non-trivial geometry modes. In this paper we prove that these modes as well as the corresponding eigenvalues are invariant under any conformal transformation. This invariance suggests a new way to study electrostatic conformal…
In the present article, for the first time, we report the synthesis of alkyl esters by direct esterification of alkali metal salts of carboxylic acids using carbon dioxide and alcohol. Methyl acetate, methyl benzoate, methyl salicylate, and methyl lactate have been synthesized by esterification of sodium acetate, sodi…
Abstract Four covalently linked trichromophore systems containing a central boron dipyrromethene (BODIPY) unit connected to a porphyrin unit through the 3‐position and a core‐modified porphyrin or a porphyrin expanded through the 5‐position were synthesized by treating 3‐bromo‐5‐porphyrinyl BODIPY or 3‐bromo‐5‐rubyrin…
The main objective of this work is to design an efficient catalyst for the synthesis of multiwalled carbon nanotubes (MWNTs) in our scalable, high quality with gram amount synthesis. The catalysts with composition of Fe, Mo, and MgO in the molar ratios 1:0.5:13, 1:1:13, and 1:1:50 were prepared by combustion method. T…
We analyze the deformation of the potential energy surface (PES) due to the incorrect description of fractional electron systems (the nonlinearity of the energy with electron number) within a (semi)local density functional theory (DFT). Particularly sensitive to this failure are polaronic systems where charge localiza…
This paper reports the design, fabrication and testing of a three-dimensional zinc–air microbattery with improved areal energy density and areal capacity, particularly at high discharge rates. The device is based on a multilayer, micron-scale, low-resistance metallic skeleton with an improved surface area. This skelet…
A novel thin-layer cellulose adsorbent bearing chemically immobilized thiosemicarbaside is synthesized. The adsorbent is used for the preconcentration of cobalt(II), mercury(II), and cadmium(II) followed by their X-ray fluorescence quantification in the concentrate. The physicochemical parameters of metal sorption are…
AzoTAB, a photosensitive azobenzene cationic surfactant, which phototriggers translation activity through light-regulated condensation of mRNA, is added to a translation solution containing several mRNAs, which can be selectively silenced by specific small RNAs. We find that gene silencing by small RNAs remains functi…
