Chiral analysis is one of the most important/challenging analytical tasks due to the necessity for differentiation of very slight differences in the molecular configurations between chiral isomers. It consists of two processes, chiral recognition and signal transduction. Quartz crystal microbalance (QCM) holds a great promise for the next-generation sensors, due to its remarkable mass sensitivity, fast response, capable of online detection and low cost. It has been the focus of academic and practical research on chiral analysis during the last two decades. This review provides a detailed overview of recent advances made in chiral analysis based on QCM detection with regard to the recognition elements, which include synthetic macromolecules, molecular imprinting polymers (MIPs), proteins, amino acids and their derivatives, etc. The prospects of using QCM for chiral analysis are also put forward. © 2014 American Scientific Publishers All rights reserved.

A novel 3D layer-pillared metal-organic framework of [Cd 3(IDC)(BDC) 1.5(H 2O)] n (1), (H 3IDC = imidazole-4,5-dicarboxylic acid, H 2BDC = 1,4-benzenedicarboxylic acid) was obtained by hydrothermal reaction, which contains rare planar hexnuclear Cd(II) cluster structural units and represents an unprecedented trinodal (4,5,14)-connected topology network. Furthermore, the thermal stability and luminescent property of 1 have also been examined. © 2012 Elsevier B.V. All rights reserved. Source

Taking account of the effect of spin softening, the shaking, swing, torsion and coupled vibration of the wind turbine blade were studied under different rotational conditions. Results show that the blade vibration frequencies increase with rising rotating velocity, while spin softening results in decrease of the vibration frequencies. Spin softening has great influence on low frequency swing, but has little influence on other vibrating mode. With the variation of rotating velocity, various order vibration frequencies of blade change at different rates, during which coupled vibration may occur. In coupled vibration, shaking mode is contained in the torsion mode, and torsion mode is also contained in the shaking mode. Coupled vibration is generally more destructive. Source

In this paper I put forward a tripartite quantum operation sharing scheme with a five-qubit entangled state presented by Brown et al. (J Phys A 38:1119, 2005). I confirm the scheme security via analysis, expose its three features and compare my scheme with others from these aspects via discussions. Besides, I reveal the experimental feasibility of the scheme with the current technologies. © 2016 Springer Science+Business Media New York Source

With the dramatically increasing prevalence of obesity and type 2 diabetes mellitus (T2DM) worldwide, there is an urgent need for new strategies to combat the growing epidemic of these metabolic diseases. Diet is an essential factor affecting the development of and risk for obesity and T2DM and it can either help or hurt. In searching for preventative and therapeutic strategies, it is therefore advantageous to consider the potential of certain foods and their bioactive compounds to reverse or prevent the pathogenic processes associated with metabolic disease. Anthocyanins are naturally occurring polyphenolic compounds abundant in dark-colored fruits, vegetables and grains. Epidemiological studies suggest that increased consumption of anthocyanins lowers the risk of T2DM. Many in vitro and in vivo studies also reveal an array of mechanisms through which anthocyanins could prevent or reverse obesity- and T2DM-related pathologies including promotion of antioxidant and anti-inflammatory activities, improvement of insulin resistance, and hypolipidemic and hypoglycemic actions. Here, we summarize the data on anthocyanin-mediated protection against obesity and T2DM and the underlying mechanisms. Further population-based and long-term human intervention studies are necessary to ultimately evaluate the use of anthocyanins for protection/prevention against the development of obesity and T2DM. © 2015 Springer Science+Business Media New York Source
