Synthesis of active tin: an efficient reagent for allylation reaction of carbonyl compounds

09-12-2014 | Arun Kumar Sinha; Amit Sil; Anup Kumar Sasmal; Mukul Pradhan; Tarasankar Pal, New Journal of Chemistry, 2014

High purity Sn(0) has been obtained as a result of reduction of SnO by sodium stannite (Na2SnO2) in aqueous solution. The process stands unique for the production of tin metal. The as-synthesized tin finds applications in synthetic organic chemistry as a reagent for the allylation of aldehydes ...

Preparation, purification, crystallization and preliminary crystallographic analysis of dual‐domain β‐propeller phytase from Bacillus sp. HJB17

08-12-2014 | Fang Lu, Gangxin Guo, Qianqian Li, Duo Feng, Yong Liu, Huoqing Huang, Peilong Yang, Wei Gao, Bin Yao, Acta Crystallographica Section F, 2014

β‐Propeller phytases (BPPs) are abundant in nature. Recently, dual‐domain BPPs have been found in which the typical BPP domain is responsible for phytate hydrolysis. The dual‐domain BPP (PhyH) from Bacillus sp. HJB17 was obtained with an incomplete N‐terminal BPP domain (PhyH‐DI; residues ...

Corrosion inhibition of AISI 1020 steel based on tungstate anion and amoxicillin as corrosion inhibitors in 0.05 mol l−1 NaCl solution or inserted into cellulose acetate films

05-12-2014 | M. C. Scholant, E. F. Coutinho, S. P. Dias, D. S. Azambuja, S. N. Silva, S. M. Tamborim, Surface and Interface Analysis, 2014

Sodium tungstate and amoxicillin were used separately or combined in a solution containing 0.05 mol l−1 NaCl or inserted into cellulose acetate films as a corrosion inhibition method for American Iron and Steel Institute (AISI) 1020 steel. The electrochemical behavior of AISI 1020 steel was ...

Structural study of caveolin‐1 intramembrane domain by CD and NMR

04-12-2014 | Guanhua Yang, Zhe Dong, Haoran Xu, Chunyu Wang, Haichao Li, Zhengqiang Li, Fei Li, Peptide Science, 2014

Abstract Caveolin‐1 is a main structural component of caveolae and essential for the invagination of caveolae by forming a hairpin structure in the membrane‐inserting domain (residues 102–122). In the present paper, we determined the tertiary structures of the peptides comprising residues ...

Reduction of Diffusive Contaminant Emissions from a Dissolved Source in a Lower Permeability Layer by Sodium Persulfate Treatment

26-11-2014 | Bridget A. Cavanagh; Paul C. Johnson; Eric J. Daniels, Environmental Science & Technology, 2014

Residual contamination contained in lower permeability zones is difficult to remediate and can, through diffusive emissions to adjacent higher permeability zones, result in long-term impacts to groundwater. This work investigated the effectiveness of oxidant delivery for reducing diffusive ...

Measurement and Thermodynamic Modeling Study on the Solid and Liquid Equilibrium of Ternary System NaBr–CaBr2–H2O at 288.15 K

26-11-2014 | Lingzong Meng; Dan Li; Tianlong Deng; Yafei Guo; Cunyun Ma; Youcai Zhu, Journal of Chemical & Engineering Data, 2014

The solubilities and refractive indices of the NaBr–CaBr2–H2O system at 288.15 K were determined using the isothermal equilibrium solution method. The phase diagram and refractive index diagram were drawn for this system at 288.15 K. The system belongs to the hydrate II type. The phase diagram is ...
