Construction of Smart Temperature-Responsive GPx Mimic Based on the Self-Assembly of Supra-Amphiphiles

24.11.2015 | Huixin Zou; Hongcheng Sun; Liang Wang; Liulu Zhao; Jiaxi Li; Zeyuan Dong; Quan Luo; Jiayun Xu; Junqiu Liu, Soft Matter, 2015

Glutathione peroxidase (GPx) is a major defense against hydroperoxides as a kind of seleno-enzyme that protects cells from oxidative damage. A supramolecular vesicle with controllable GPx activity and morphology has been successfully constructed by the self-assembly of supra-amphiphiles formed by ...


Gelation Behaviour of a Bent-core Dihydrazide Derivative : Effect of Incubation Temperature in Chloroform and Toluene

24.11.2015 | Chunxue Zhang; Tian ren Zhang; Nan Ji; Yan Zhang; Binlian Bai; Haitao Wang; Min Li, Soft Matter, 2015

In this work, a new kind of gelator, 1,3-bis[(3,4-dioctloxy phenyl) hydrazide] phenylene (BP8-C), containing two di-hydrazide units as the rigid bent-core, had been synthesized and investigated. It is demonstrated that BP8-C is an efficient gelator which can gel various organic solvents such as ...


Solvent specific synthesis of nano corpse flowery lithiated iron oxide as an energy storage and gas sensing material

24.11.2015 | Rasmita Barik; K. T. Leung; Mamata Mohapatra, New Journal of Chemistry, 2015

Iron oxide based materials are one of the most appealing matrices and promising futuristic materials for energy conversion/storage devices. The solvent dependent synthesis and growth of lithiated iron oxide/LiFeO2 nano flowers was established using a simple sol–gel method at low temperature. ...


Induced stabilization of columnar phases in binary mixtures of discotic liquid crystals

24.11.2015 | Octavio Cienega-Cacerez; Consuelo García-Alcántara; José Antonio Moreno-Razo; Enrique Díaz-Herrera; Edward John Samb ..., Soft Matter, 2015

Three discotic liquid-crystalline binary mixtures, characterized by their extent of bidispersity in molecular thickness, were investigated with molecular dynamics simulations. Each equimolar mixture contained A-type (thin) and B-type (thick) discogens. The temperature-dependence of the ...


Synthesis and Applications of Fluorescent Polymers as Fluorescent Probes

24.11.2015 | Ye, Qianghua; Yan, Fanyong; Kong, Depeng; Wang, Jing; Zhou, Xuguang; Chen, Li, Organic Chemistry, 2015

Abstract: Fluorescent probes possess low limit, high sensitivity, and wide response range, etc. but they have some disadvantages including contamination to the detection system, limitation of repeated use. Polymers combined with fluorescent probes could overcome these drawbacks and they ...


Direct-growth carbon nanotubes on 3D structural microelectrodes for electrophysiological recording

24.11.2015 | Alice Ian Pan; Min-Hsuan Lin; Hui-Wen Chung; Hsin Chen; Shih-Rung Yeh; Yung-Jen Chuang; Yen-Chung Chang; Tri-Rung Yew, Analyst, 2015

A novel 3D carbon nanotube (CNT) microelectrode was developed through direct growth of CNTs on a gold pin-shaped 3D microelectrode at a low temperature (400 °C) for applications in neural and cardiac recording. With an electroplated Ni catalyst layer covering the entire surface of the pin-shaped ...


An eco-friendly method for reclaimed silicon wafers from a photovoltaic module: from separation to cell fabrication

24.11.2015 | Jongsung Park; Wangou Kim; Namjun Cho; Haksoo Lee; Nochang Park, Green Chemistry, 2015

A sustainable method for reclaiming silicon (Si) wafers from an end-of-life photovoltaic module is examined in this paper. A thermal process was employed to remove ethylene vinyl acetate and the back-sheet. We found that a ramp-up rate of 15 °C min−1 and an annealing temperature of 480 °C enabled ...


Geometric order parameters derived from the Voronoi tessellation show signatures of the jamming transition

24.11.2015 | Peter K Morse; Eric I Corwin, Soft Matter, 2015

A jammed packing of frictionless spheres at zero temperature is perfectly specified by the network of contact forces from which mechanical properties can be derived. However, we can alternatively consider a packing as a geometric structure, characterized by a Voronoi tessellation which encodes ...


Acylation of indoles via photoredox catalysis: a route to 3-acylindoles

24.11.2015 | Lijun Gu; Cheng Jin; Jiyan Liu; Hongtao Zhang; Minglong Yuan; Ganpeng Li, Green Chemistry, 2015

A visible-light-induced synthesis of 3-acylindoles from simple indoles and α-oxo acids at room temperature has been discovered. The reaction tolerates a wide range of functional groups and gives a variety of valuable 3-acylindoles in moderate to high yields under mild conditions.


Hydroamination of Diphenylbutadiyne with Secondary N-Methyl-anilines Using the Dipotassium Tetrakis(2,6-diisopropylanilino)calciate Precatalyst

24.11.2015 | Matthias Westerhausen; Fadi M Younis; Sven Krieck; Helmar Görls, Dalton Transactions, 2015

The approved precatalyst [K2Ca{N(H)Dipp}4] was employed to study the hydroamination of diphenylbutadiyne with N-methyl-anilines in tetrahydrofuran at room temperature. The hydroamination occurs regioselectively within a few hours yielding (N-methyl)-(N-aryl)-1,4-diphenylbut-1-ene-3-yne-1-ylamine ...
