Hydrogen is an essential substance for green-energy applications. The production of hydrogen-based on renewable energy sources has a critical role in this context. Thermochemical methods based solar are getting attention hydrogen sustainable manner. It possible to produce without the need purification via two-step thermochemical water splitting (TWS) method. thermodynamics and kinetics redox re...

This paper deals with the design and fabrication of a quartz-crystal resonator used in a thickness-monitor unit, measuring film thickness in a film-depositing system. A purpose-grown quartz crystal is cut to form the desired wafer. Two gold electrodes are deposited on both surfaces of the wafer to provide electrical contacts. The resonance frequency of the resonator, at room temperature, and th...

the structure of n,n'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, c19h22n2o2, has been studied at low temperature (120k) by means of single-crystal x-ray diffraction. solving the structure shows an orthorhombic unit cell, with p212121 space group, z = 4, a = 6.1046 (4) å, b = 15.8349 (11)å, c = 17.2898 (12) å and v = 1671.3 (2) å3. there are two relatively strong hydrogen bonds (...

Protein crystallization can serve as a purification step in biotechnological processes but is often limited by the non-crystallizability of proteins. Enabling or improving mostly achieved high-throughput screening conditions and, more recently, rational crystal contact engineering. Two selected mutations, Q126K and T102E, were transferred from alcohol dehydrogenases Lactobacillus brevis (LbADH)...

background: botulinum neurotoxin (bont) complexes consist of neurotoxin and neurotoxin-associated proteins. hemagglutinin-33 (ha-33) is a member of bont type a (bont/a) complex. considering the protective role of ha-33 in preservation of bont/a in gastrointestinal harsh conditions and also its adjuvant role, recombinant production of this protein is favorable. thus in this study, ha-33 was expr...

background and objective: use of elastin-like proteins (elps) provides high-performance protein purification without need for chromatography. in line with cost reduction and facilitation of recombinant proteins purification, which represent a high percentage of production costs, in this project, we eliminated the need for proteases in the process of separation of recombinant proteins from elp b...

In this study phase- pure new spinel structure, Mn0.5Cu0.5Cr2O4 was prepared by hydrothermal method successfully and the degradation of Malachite green as an organic pollutant was investigated and compared with CuCr2O4. Purification of obtained nanoparticles was measured by using X-ray diffraction method (XRD) in which crystal st...

In this research, pure-phased Ni0.5Cu0.5Cr2O4 synthesis via solid-state method successfully. In the other part, the photocatalytic activity of synthesized Ni0.5Cu0.5Cr2O4 was investigated in various aspects by using Malachite green as a pollutant and compared with the number of previous photocatalysts. T...

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
