Recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. Genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. Differed methods for protein purification are categorized, based on cast, quality, Easy work and side effect of protein. In this article, we are investigating his His-tag protein pu...

Polyimide/Nickel oxide (polyimide/NiO) nanocomposite was successfully synthesized by sol gel technique, using Pyromellitic dianhydriede (PMDA), 4,4-oxydianiline (ODA) and N,N-dimethylacetamide (DMAC) and 10 wt% Nickel titanate nanopowders (NPs). Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) we...

Methyl orange is one dye resulted from the textile industry. The aim of this study is to test theadsorption capacity of nickel oxide nanoparticles for removing the methyl orange from aqueoussolution. The parameters studied were the effect of temperature, contact time and initial pH ofsolution. Results indicate that the removal efficiency of nickel oxide nanoparticles increases withincreasing co...

A nanocomposite adsorbent based on potassium nickel hexacyanoferrate-loaded polypropylene fabric was synthesized for selective removal of Cs ions from contaminated waters by a two-stage synthesis: radiation-induced graft polymerization of acrylic acid monomer onto the nonwoven polypropylene fabric surface with subsequent in situ formation of potassium nickel hexacyanoferrate (KNiHCF) nanopartic...

A new family of magic cluster structures is found by genetic global optimization, whose results are confirmed by density functional calculations. These clusters are Ag-Ni and Ag-Cu nanoparticles with an inner Ni or Cu core and an Ag external shell, as experimentally observed for Ag-Ni, and present a polyicosahedral character. The interplay of the core-shell chemical ordering with the polyicosah...

Two different nickel precursors (NiCl2 or Ni(CH3COCH2COCH3)2) in the presence of 1-dodecanethiol and a mixture of oleylamine and oleic acid were used for a one-pot colloidal synthesis to produce high purity Ni3S4 nanoparticles with controlled shapes in high yields and narrow size distributions. By simply changing the nickel precursors, the shape of Ni3S4 nanocrystals can be readily tuned from t...

We demonstrate the formation of hollow nickel germanide nanostructures of Ni-Ge core-shell nanoparticles by solid state reactions. The structural evolutions of nickel germanide hollow nanostructures have been investigated in real-time ultrahigh vacuum transmission electron microscopy (UHV-TEM). Annealed above 450 °C, the nonequilibrium interdiffusion of core and shell species occurred at the in...
