Synergism between polyurethane and polydopamine in the synthesis of Ni-Fe alloy monoliths

17.12.2014 | Thangavel Nareshkumar; Santhana Sivabalan; Naveen Chandrasekaran; Phani KLN, Chemical Communication, 2014

Herein, we report the first synthesis of light-weight macroporous 3-D alloy monolith of Ni-Fe/C using synergism between polydopamine (pDA) and polyurethane (pU); in situ formed polyurethane (pU) enables efficient mixing of pDA (carbon source) and Ni-FeOx resulting in Ni-Fe alloy monoliths at a ...

Catalytic reforming of acetic acid as a model compound of bio‐oil for hydrogen production over Ni‐CeO2‐MgO/olivine catalysts

11.12.2014 | Xingmin Xu, Changsen Zhang, Yonggang Liu, Yunpu Zhai, Ruiqin Zhang, Xiaoyan Tang, Environmental Progress, 2014

Olivine was used as a support with CeO2/MgO as promoters to synthesize a series of Ni‐based catalysts by wet impregnation for reforming acetic acid as a model compound of bio‐oil for H2 production. These catalysts were characterized by X‐ray diffraction, N2 physisorption, and scanning electron ...

Investigation of the Enantiomerization Barriers of the Phthalimidone Derivatives EM12 and Lenalidomide by Dynamic Electrokinetic Chromatography

11.12.2014 | Sarah Walz, Sylvia Weis, Mareike Franz, Frank Rominger, Oliver Trapp, ELECTROPHORESIS, 2014

The phthalimidone derivatives EM12 and lenalidomide, which are both structurally related to thalidomide, are highly interesting drugs and very recently lenalidomide attracted great attention as anti‐tumor and immune‐modulating drug [1] in the therapy for multiple myeloma [1]. EM12 and ...

Decarbonylative Radical Coupling of α‐Aminoacyl Tellurides: Single‐Step Preparation of γ‐Amino and α,β‐Diamino Acids and Rapid Synthesis of Gabapentin and Manzacidin A

10.12.2014 | Masanori Nagatomo, Hayato Nishiyama, Haruka Fujino, Masayuki Inoue, Angewandte Chemie International Edition, 2014

Abstract A new radical‐based coupling method has been developed for the single‐step generation of various γ‐amino acids and α,β‐diamino acids from α‐aminoacyl tellurides. Upon activation by Et3B and O2 at ambient temperature, α‐aminoacyl tellurides were readily converted into α‐amino carbon ...

Effect of fatty acid on the formation of ITO nanocrystals via one-pot pyrolysis reaction

10.12.2014 | Shaojuan Luo; Jiyun Feng; Ka Ming Ng, CrystEngComm, 2014

Indium-tin carboxylate precursors were successfully synthesized by a direct reaction of indium and tin metals with a molten fatty acid under a nitrogen atmosphere at 260 °C. A linear relationship between the reaction initiation temperature and the number of carbon atoms of the fatty acids ranging ...

Hydrogen Production by the Water–Gas Shift Reaction Using an Atmospheric Steam Plasma Torch System with a Reverse Vortex Reactor

10.12.2014 | Suk H. Ma; Dae H. Choi; Se M. Chun; Sang S. Yang; Yong C. Hong, Energy & Fuels, 2014

The water–gas shift reaction (WGSR) using a pure steam plasma with CO as the reactant was accomplished in this study. The steam plasma generated by microwaves at an atmospheric pressure provides highly active species and a high-temperature plasma flame at about 6000 K, which enhances the chemical ...
