Treatment of ethanolamine using an Fe(III)‐based, two‐chamber microbial fuel cell with continuous Fe(II) oxidation at the air cathode

23-May-2015 | Seok‐Ju Seo, Ja‐Won Shin, Hubdar Ali Maitlo, Joo‐Yang Park, Journal of Chemical Technology & Biotechnology, 2015

Abstract Background The objective of this study was to investigate the feasibility of developing an integrated bio‐electrochemical system for the removal of ethanolamine from wastewater by combining an Fe(III)‐based microbial fuel cell (MFC) with a continuous Fe(II) oxidation system for ...


Precipitation of Amorphous Calcium Oxalate in Aqueous Solution

22-May-2015 | Johannes Ihli; Yun-Wei Wang; Bram Cantaert; Yi-Yeoun Kim; David C. Green; Paul H. H. Bomans; Nico A. J. M. Sommerdij ..., Chemistry of Materials, 2015

Inspired by the observation that crystalline calcium carbonate and calcium phosphate biominerals frequently form via amorphous precursors, a wide range of studies have been performed which demonstrate that many inorganic crystals can precipitate from solution via amorphous phases. This article ...


Separation of cobalt(II) from manganese(II) using a polymer inclusion membrane with N‐[N,N‐di(2‐ethylhexyl)aminocarbonylmethyl]glycine (D2EHAG) as the extractant/carrier

19-May-2015 | Yuzo Baba, Fukiko Kubota, Masahiro Goto, Robert W. Cattrall, Spas D. Kolev, Journal of Chemical Technology & Biotechnology, 2015

Abstract BACKGROUND The hydrometallurgical separation of Co(II) from Mn(II) poses a difficult problem because of their similar chemical and physical properties. We have attempted to develop a membrane separation method for Co(II) in the presence of Mn(II) which overcomes the potential ...


Supramolecular Assembly of Isocyanorhodium(I) Complexes: An Interplay of Rhodium(I)···Rhodium(I) Interactions, Hydrophobic–Hydrophobic Interactions, and Host–Guest Chemistry

18-May-2015 | Alan Kwun-Wa Chan; Keith Man-Chung Wong; Vivian Wing-Wah Yam, Journal of the American Chemical Society, 2015

A series of tetrakis(isocyano)rhodium(I) complexes with different chain lengths of alkyl substituents has been found to exhibit a strong tendency toward solution state aggregation upon altering the concentration, temperature and solvent composition. Temperature- and solvent-dependent UV–vis ...


Preparation and characterization of poly(ethylene oxide)‐loaded hydroxypropyl‐β‐cyclodextrin nanofibers

15-May-2015 | M. Forhad Hossain, R. Hugh Gong, Muriel Rigout, Polymers for Advanced Technologies, 2015

Hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD) is a modified β‐cyclodextrin (β‐CD) derivative, which is toxicologically harmless to mammals and other animals. HP‐β‐CD is electrospun from an aqueous solution by blending with a non‐toxic, biocompatible, synthetic polymer poly(ethylene oxide) (PEO). ...


Toward a Quantitative Understanding of Symmetry Reduction Involved in the Seed-Mediated Growth of Pd Nanocrystals

15-May-2015 | Hsin-Chieh Peng; Jinho Park; Lei Zhang; Younan Xia, Journal of the American Chemical Society, 2015

We report a quantitative analysis of the symmetry reduction phenomenon involved in the seed-mediated growth of Pd nanocrystals under dropwise addition of a precursor solution. In addition to the elimination of self-nucleation, the dropwise approach allows for the formation of a steady state for ...


Effects of nano‐tio2 on the performance of high‐amylose starch based antibacterial films

14-May-2015 | Chao Liu, Hanguo Xiong, Xing Chen, Shun Lin, Yanhua Tu, Journal of Applied Polymer Science, 2015

ABSTRACT The purpose of this article is to investigate the effects of nano‐tianium dioxide (nano‐TiO2) on the high‐amylose starch/polyvingl alcohol (PVA) blend films prepared by a solution casting method. The results show that at the concentration of 0.6% of nano‐TiO2, the film demonstrated ...


Salting‐Out of Acetone, 1‐Butanol, and Ethanol from Dilute Aqueous Solutions

14-May-2015 | Shaoqu Xie, Conghua Yi, Xueqing Qiu, AIChE Journal, 2015

ABSTRACT The salting‐out phase equilibria for acetone, 1‐butanol, and ethanol (ABE) from dilute aqueous solutions by using potassium carbonate (K2CO3) and dipotassium hydrogen phosphate trihydrate (K2HPO4·3H2O) as outstanding salting‐out agents were investigated. Increasing the salt ...


Diamond crystals deposited from interacting jets

13-May-2015 | Aleksey Rebrov, Aleksey Emelyanov, Sergey Kosolobov, Ivan Yudin, physica status solidi (c), 2015

Abstract This paper describes the advancement of hot wire or hot filament CVD methods of diamond synthesis through the use high velocity gas flow activation by multiple collisions with a lengthy hot surface instead of activation by single collisions with hot wires. The possibility of synthesis ...


Oil‐in‐Water Emulsion Exhibits Bitterness‐Suppressing Effects in a Sensory Threshold Study

13-May-2015 | Damir Dennis Torrico, Amporn Sae‐Eaw, Sujinda Sriwattana, Charles Boeneke, Witoon Prinyawiwatkul, Journal of Food Science, 2015

Abstract Little is known about how emulsion characteristics affect saltiness/bitterness perception. Sensory detection and recognition thresholds of NaCl, caffeine, and KCl in aqueous solution compared with oil‐in‐water emulsion systems were evaluated. For emulsions, NaCl, KCl, or caffeine were ...
