Molecules, Vol. 20, Pages 15304-15318: Optimization of Micellar Electrokinetic Chromatography Method for the Simultaneous Determination of Seven Hydrophilic and Four Lipophilic Bioactive Components in Three Salvia Species

21-Aug-2015 | Cao, Jiliang ; Hu, Ji ; Wei, Jinchao ; Li, Baocai ; Zhang, Mi ; Xiang, Cheng ; Li, Peng, Molecules, 2015

A micellar electrokinetic chromatography (MEKC) method was developed for the simultaneous determination of seven hydrophilic phenolic acids and four lipophilic tanshinones in three Salvia species. In normal MEKC mode using SDS as surfactant, the investigated 11 compounds could not be well ...

Mesoporous Pores Impregnated with Au Nanoparticles as Effective Dielectrics for Enhancing Triboelectric Nanogenerator Performance under Harsh Environment

19-Aug-2015 | Jinsung Chun; Jin Woong Kim; Woo-Suk Jung; Chong-Yun Kang; Sang-Woo Kim; Zhong Lin Wang; Jeong Min Baik, Energy & Environmental Science, 2015

A facile and scalable synthesis of mesoporous films impregnated with Au nanoparticles (NPs) as effective dielectrics is demonstrated for enhancing the nanogenerator performance based on vertical contact-separation mode. This technique is so simple and scalable, providing a promising solution for ...

Raman Spectroscopic Observations of the Ion Association between Mg2+ and SO42– in MgSO4-Saturated Droplets at Temperatures of ≤380 °C

17-Aug-2015 | Ye Wan; Xiaolin Wang; Wenxuan Hu; I-Ming Chou, Journal of Physical Chemistry A, 2015

Liquid–liquid phase separation was observed in aqueous MgSO4 solutions with excess H2SO4 at elevated temperatures; the aqueous MgSO4/H2SO4 solutions separated into MgSO4-rich droplets (fluid F1) and a MgSO4-poor phase (fluid F2) during heating. The phase separation temperature increases with ...

Engineering Design of Outer‐Selective Tri‐bore Hollow Fiber Membranes for Forward Osmosis and Oil‐Water Separation

14-Aug-2015 | Xue Li, Wan Lin Ang, Yingda Liu, Tai‐Shung Chung, AIChE Journal, 2015

Abstract Outer‐selective thin‐film composite (TFC) hollow fiber membranes offer advantages like less fiber blockage in the feed stream and high packing density for industrial applications. However, outer‐selective TFC hollow fiber membranes are rarely commercially available due to the lack of ...

Effect of Halogenation in Isoindigo-Based Polymers on the Phase Separation and Molecular Orientation of Bulk Heterojunction Solar Cells

14-Aug-2015 | Yu-Qing Zheng; Zhi Wang; Jin-Hu Dou; Shi-Ding Zhang; Xu-Yi Luo; Ze-Fan Yao; Jie-Yu Wang; Jian Pei, Macromolecules, 2015

Fluorinated and chlorinated isoindigo-based polymers, F-IIDT and Cl-IIDT, were developed as the donor materials for photovoltaic cells. Although showing similar frontier orbital energy levels, both polymers exhibited distinct solar cell device performance, for example, power conversion efficiency ...

Macrocyclic Weakly Coordinating Anions

13-Aug-2015 | Kai Landskron, Chemistry - A European Journal, 2015

Abstract Herein, the concept of macrocyclic weakly coordinating anions (M‐WCAs) is introduced. Synthetic methodologies are described how to access M‐WCAs by thermodynamically controlled self‐assembly in high yields, in particular through condensation and alkyne metathesis reactions. The ...

Li+–Oligoglyme Association in the Presence of Ionic Liquid Studied by Molecular Dynamics and Explicit or Implicit Solvent Model

13-Aug-2015 | Andrzej Eilmes; Piotr Kubisiak, Journal of Physical Chemistry B, 2015

Molecular dynamics simulations have been applied to study properties of ternary oligoglyme/ionic liquid/lithium salt electrolytes. Different types of lithium coordination and phase behavior have been observed depending on the liquid/salt anion: from full phase separation and Li+ coordination ...

Mitigation of Salinity Buildup and Recovery of Wasted Salts in a Hybrid Osmotic Membrane Bioreactor–Electrodialysis System

13-Aug-2015 | Yaobin Lu; Zhen He, Environmental Science & Technology, 2015

The osmotic membrane bioreactor (OMBR) is an emerging technology that uses water osmosis to accomplish separation of biomass from the treated effluent; however, accumulation of salts in the wastewater due to water flux and loss of draw solute because of reverse salt flux seriously hinder OMBR ...

Predicting multicomponent adsorption: 50 years of the ideal adsorbed solution theory

07-Aug-2015 | Krista S. Walton, David S. Sholl, AIChE Journal, 2015

Describing multi‐component adsorption is fundamental to using sorption in any chemical separation. 50 years ago, Myers and Prausnitz made a seminal contribution to characterization and prediction of multi‐component adsorption by introducing Ideal Adsorbed Solution Theory (IAST). Here, we give an ...
