Structure-guided genetic engineering of D-phenylglycine aminotransferase (D-PhgAT) aimed at increasing protein solubility was attempted. In silico analyses predicted the Asn439 and Gln444 as highly solvent-exposed β-turn residues involved with protein crystal contact (CC) potential candidates for solubility-improving…
It has been reported that cracks grow along {100} independent of the tensile direction in hydrogen embitterment in nickel single crystal. Behavior of crack initiation by cathodic hydrogen charging was investigated in the present work to clarify the mechanism of hydrogen embrittlement. Hydrogen was charged on (100) or…
For the investigation of the superconducting properties of iron-based superconductors Josephson junctions as well as Andreev reflection studies are potential tools. Therefore, we prepared different kinds of junctions, based on transport in direction of c-axis and ab-plane, respectively. The first one was a planar hybr…
The article presents systematic research on Langmuir films of partially fluorinated bolaamphiphiles of different shapes. Such films exhibit a layering transition from a monolayer to a trilayer during compression on the air–water interface. Further compression gives different results depending on the shape and degree o…
Bulk nanocrystalline gadolinium metals have been consolidated from gadolinium nanoparticles using spark plasma sintering. Transmission electron microscopy observation shows that SPS technique can effectively restrain the grain growth in bulk Gd metals. The adiabatic temperature changes of the as-consolidated and coars…
A series of novel chlorophyll-a homologs with long wavelength absorption were synthesized via modification of methyl pyropheophorbide-a used as starting material. For introducing electron-withdrawing group methylenemalononitrile moiety was established on the periphery of modified chlorin by Knoevenagel reaction of mal…
Hierarchical high-density well-aligned branched ZnO nanostructures are prepared on conductive glass substrates via a facile strategy with an aqueous solution process. The formation mechanism of ZnO array on a ZnO array is discussed based on the coincident lattice between the trunk and branches. Dye-sensitized solar ce…
From 2007 to 2008, many bronze wares of Qin Dynasty were excavated from tombs at Xinfeng town. Being an important finding, these bronze wares attracted people’s attention, especially for their conservation. Therefore, the corrosive products were explored by using Scanning Electron Microscope with Energy Dispersive X-r…
The aim of this research was to study the metal elements in Perna Viridis shell. Energy Dispersive X-Ray Fluorescence (EDXRF) spectrometer was used to determine the composition of mineral and levels of the metals element. Furthermore, the Perna Viridis shell samples were prepared in powder form and investigate the str…
Different shapes and sizes of TOPO-capped ZnO nanostructures have been obtained by the decomposition of the cupferron complex in the presence of tri-n-octylphosphine oxide (TOPO) under different conditions. The precursor : TOPO ratio, the order of reactants and thermal decomposition temperature play important roles in…
The aim of this study was the preparation of polyethylene oxide (PEO)/clay nanocomposites using organoclay produced via micellar adsorption of cethyltrimethyl ammonium bromide (CTAB) and their characterisation by X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectra, and the investigation of certain…
This paper describes an activation-free preparation of porous carbon by carbonization of a phenolic resin (PF) containing pore formers such as m-phthalic acid (PA), trimesic acid (TMA), and phloroglucinol (PG). Monitoring of their carbonization behaviors by thermogravimetric analysis (TGA) and differential scanning ca…
Formation of unique ZnO nanoarrays utilizing photodynamic polymer, surface‐relief grating structures, and unique electrostatic layer‐by‐layer assembly as a simple and economical methodology was demonstrated. Atomic force microscope (AFM), scanning electron microscopy (SEM), and energy‐dispersive X‐ray (EDAX) analysis…
We report a novel approach to prepare magnetic metal (e.g.Ni, Co and Fe) nanowire arrays by reduction of metal chloride salts in the pores of an anodic aluminum oxide (AAO) template with a backside Al sheet via a hydrothermal process. When a magnetic field was applied during the redox reaction, the Ni nanoarrays exhib…
Monodisperse magnetite (Fe3O4) and cobaltous oxide (CoO) nanoparticles were synthesised using a fast (up to 50 times quicker than previously reported) and facile one-pot, one-step reaction. The Fe3O4 nanoparticles had a constant size between 5 to 7 nm independent of the reagents used. Size controlled cube shaped CoO p…
The effective thermal conductivity (ETC) of polymer composites is studied using artificial neural networks. Artificial neural networks are a form of artificial intelligence, which attempt to mimic the function of the human brain and nervous system. Artificial neural networks provide a great deal of promise but they su…
Cholesteric liquid crystals selectively reflect circularly polarised light with the same handedness as the helix. Because of their sensitivity to external stimuli, such as heat and electrical fields, various applications utilising their tunability have been proposed. Tuning is usually performed in the bulk, meaning th…
In Northern Israel, olive mills discharge liquid waste causing contamination of subterranean aquifers with phenol, rendering them albeit temporarily, unfit for both drinking and irrigation. The impact of groundwater pollution due to phenol spillage can be extensive. We developed a model system for the biodegradation o…
Selenium nanostructures, which are otherwise susceptible to oxidative damage, were encapsulated with a thin layer of polystyrene. The thin layer of polystyrene was grafted onto the surfaces of selenium by a surface initiated atom transfer radical polymerization reaction. These encapsulated nanostructures demonstrate a…
The scattering of atomic and molecular beams from well-characterized surfaces is a useful method for studying the dynamics of gas-surface interactions, providing precise information on the energy and momentum exchange which occur in such encounters. We apply this technique to new systems including disordered films of…
