Tissue scaffolds play a crucial role in the tissue regeneration process. The ideal scaffold must fulfill several requirements such as having proper composition, targeted modulus, and well-defined architectural features. Biomaterials that recapitulate the intrinsic architecture of in vivo tissue are vital for studying…
Processes of high-speed shaping changes and especially high-speed hot extrusion create efficient conditions for treatment of weakly plastic and poorly deformable materials which are widely used in tool making facilities. Due to the fact that high-speed stamping provides accurate billets with increased mechanical prope…
CuInSe2 as one I-III-VI ternary compound with direct band gap, has become one of the most promising photovoltaic materials due to high optical absorption coefficient and conversion efficiency. CuInSe2 films were prepared by electrodeposition with CuCl2·2H2O, InCl3, SeO2 as raw materials. The phases of product films we…
The microstructures and magnetic properties of Zr2Co11phase prepared by a rapid solidification method and subsequent annealing at 500 °C were studied using X-ray diffraction and electron diffraction. At a wheel surface velocity of 20 m/s, both orthorhombic and rhombohedral structures were observed in as-spun ribbons.…
Bi2S3 quantum dots modified mesoscopic TiO2 films were prepared by in-situ solution chemical reaction deposition, using ethylene glycol monomethylether (EGME) and ethanol as solvent of Cationic precursor solution and anionic precursor solution respectively. UV-vis-NIR absorption spectra reveal that the Bi2S3 QDs exten…
In this study, it is found that amylose stereoselectively includes poly(d‐alanine) in the polyalanine stereoisomers in vine‐twining polymerization to form the corresponding inclusion complex, a novel saccharide–peptide supramolecular conjugate. The vine‐twining polymerization is performed by thermostable phosphorylase…
A gravimetric method was taken to measure the solubility of the Boc-(R)-3-amino-4-(2,4,5-trifluorophenyl)butanoic acid under atmospheric pressure in methanol, ethanol, propanol, n -butanol, ethyl acetate, and tetrahydrofuran as well as in the (tetrahydrofuran + n -butanol) mixtures from 280.15 to 330.15 K.The experime…
The structural and electronic properties of multilayer graphene adsorbed on monolayer hexagonal boron nitride (h-BN)/Ni(111) interface system are investigated using the density functional theory with a recently developed non-local van der Waals density functional (rvv10). The most energetically favourable configuratio…
A synthesis technique which can lead to direct integration of tungsten oxide nanowires onto silicon chips is essential for preparing various devices. The conversion of amorphous tungsten films deposited on silicon chips by pulsed layer deposition to nanowires by annealing is an apt method in that direction. This persp…
Two new benzothiazolyl calix[4]arene-based multitopic molecular receptors L-1 and L-2 have been synthesised and evaluated for recognition of ionic toxicants. The receptors selectively interact with copper, silver and fluoride ion toxicants as assessed through UV-visible, NMR and colorimetric techniques. The stability…
Heat shock protein 90 (HSP90) is a molecular chaperone required for the stability and function of many proteins. The chaperoning of oncoproteins by HSP90 enhances the survival, growth, and invasive potential of cancer cells. HSP90 inhibitors are promising new anticancer agents, in which the benzoquinone ansamycin 17-a…
The optimal conditions for the burn regimes of a tokamak fusion power plant are obtained under the assumption that electron and ion temperatures can be controlled independently by means of external auxiliary heating. The study of the system is based on a volume-averaged 0-D two-temperature model in which different ope…
The system {(water (1) + butyric acid (2) + phenyl acetate (3)} at different temperatures, such as 298.15 K, 308.15 K, 318.15 K, and at a constant pressure (101.3 ± 0.5 kPa) in terms of liquid liquid phase equilibria were investigated. The solubility curves for each system were found. The consistency for the experimen…
Triangular Ag nanoplates were prepared using AgNO3, PVP, NaBH4, Na3CA and H2O2 as reagents. The obtained triangular Ag NPs were characterized by transmission electron microscopy and UV-visible spectrophotometer. TEM results showed that, the edge lengths of triangular Ag NPs were in the range of 35–95 nm. The thickness…
The high pressure structural and reactive beahvior of graphene oxide (GO) in the presence of Ar, N 2, and NH 3 was studied in diamond anvil cells (DAC) by X-ray diffraction (XRD) and vibrational spectroscopy (FTIR and Raman), with the purpose of investigating the use of pressure for N-doping and functionalization of G…
Acid-catalyzed [3+3] condensation reactions of two hitherto unknown tripyrrane moieties with pentafluorobenzaldehyde has led to the formation of new generation heteroannulene (4.1.4.1) and mutant heteroannulene (1.1.1.1.1.1). Inclusion of local π-aromatic sextets, namely the N-methyl pyrrole rings through β,β-linkages…
The transamination-chemistry-based process for sitagliptin is a through-process, which challenges the crystallization of the active pharmaceutical ingredient (API) in a batch stream composed of multiple components. Risk-assessment-based design of experiment (DoE) studies of particle size distribution (PSD) and crystal…
While manufacturing a number of important tubular products stringent requirements have been imposed on quality of their inner surfaces. The well-known methods for inner surface treatment of pipes include sandblasting, chemical cleaning with acid reagents (oxalic, formic, sulfamic, orthophosphoric acids) and electroche…
The zero-refraction property of a metal film can be used to image so that the metal film behaves as a superlens. Experimentally, the metal superlens is sandwiched between the photosensitivity resist (PR) and the dielectric spacer in the photolithograph device to produce images. In this paper, the imaging conditions of…
Aspartate-β-semialdehyde dehydrogenase (ASADH) catalyzes the second reaction in the aspartate pathway, a pathway required for the biosynthesis of one fifth of the essential amino acids in plants and microorganisms. Microarray analysis of a fungal pathogen T. rubrum responsible for most human dermatophytoses identified…
