Understanding of the low temperature auto-oxidation scheme of sec-alcohols based on a Cu(II)-MOF with open metal sites

28.07.2015 | Yu-Bin Dong; Jian-Ping Ma; Chao-Wei Zhao; Shen-Qing Wang; Jin-Ping Zhang, Chemical Communication, 2015

The Cu(II)-MOF (1’) with open metal sites was readily obtained by removing the coordinated water molecule at 120˚C. It can be a probe to evidence the sec-alkyl hydroperoxide species generated from the room temperature sec-alcohol auto-oxidation in air. The formed alkyl hydroperoxides can be ...

Effect of cross‐linked waxy maize starch on the quality of non‐fried instant noodles

24.07.2015 | Man Zhou, Zhouyi Xiong, Jie Cai, Hanguo Xiong, Starch - Stärke, 2015

Abstract In this study, the effects of cross‐linked waxy maize starch (CLWMS) on non‐fried instant noodles were studied. Noodles were prepared from reconstituted flours by substituting wheat flour at 10%, 20% and 30% with CLWMS. The pasting properties, rheology, cooking qualities, texture, ...

IJERPH, Vol. 12, Pages 8619-8630: Physico-Chemical and Microbial Analysis of Selected Borehole Water in Mahikeng, South Africa

23.07.2015 | Palamuleni, Lobina ; Akoth, Mercy, International Journal of Environmental Research and Public Health, 2015

Groundwater is generally considered a “safe source” of drinking water because it is abstracted with low microbial load with little need for treatment before drinking. However, groundwater resources are commonly vulnerable to pollution, which may degrade their quality. An assessment of microbial ...

Surface Activity and Aggregation Behavior of Siloxane-Based Ionic Liquids in Aqueous Solution

23.07.2015 | Guoyong Wang; Ping Li; Zhiping Du; Wanxu Wang; Guojin Li, Langmuir, 2015

Six novel siloxane-based surface-active ionic liquids (SAILs)—siloxane ammonium carboxylate [Si(n)N(2)-CA(1), (n = 3, 4)]—were designed and synthesized. Their melting points, surface activities, and self-aggregation behavior in aqueous solution were studied. The results showed that because of the ...
