An Efficient Palladium Catalyst on Bentonite for Suzuki-Miyaura Reaction at Room Temperature

18.09.2013 | Tao Jiang; Guodong Ding; Weitao Wang; Prof. Buxing Han, Green Chemistry, 2013

Clays are nontoxic, abundant, and cheap, which are very promising supports for designing and preparing green catalysts. In this work, Pd/Bentonite catalyst was fabricated by a simple impregnation method using water as the medium. The catalyst was characterized by powder X-ray diffraction (XRD), ...

Cool Microcontact Printing To Fabricate Thermosensitive Microgel Patterns

13.09.2013 | Jiaxi Peng; Dan Zhao; Xiaofeng Tang; Fei Tong; Li Guan; Yapei Wang; Meining Zhang; Tingbing Cao, Langmuir, 2013

A facile method, cool microcontact printing (cool μCP), of fabricating microgel patterns under ambient conditions is developed. By using spontaneously condensed water on the surface of cold items and the phase transition of polymer microgels below the lower critical solution temperature (LCST), a ...

Low-temperature, solution-processed, layered V2O5 hydrate as the hole-transport layer for stable organic solar cells

11.09.2013 | Gerardo Terán-Escobar; Jonas Pampel; José M. Caicedo; Mónica Lira-Cantú, Energy & Environmental Science, 2013

Layered V2O5 hydrate has been applied as the hole transport layer (HTL) in organic solar cells (OSCs). V2O5 is obtained from a sodium metavanadate solution in water under ambient conditions, resulting in a final thin film of formula V2O5·0.5H2O. The 0.5 water molecules are not removed from the ...

Production of Gas Phase NO2 and Halogens from the Photolysis of Thin Water Films Containing Nitrate, Chloride and Bromide Ions at Room Temperature

11.09.2013 | Nicole Richards-Henderson; Karen Callahan; Paul Nissenson; Noriko Nishino; Douglas J Tobias; Barbara J. Finlayson-Pitts, Physical Chemistry Chemical Physics, 2013

Nitrate and halide ions coexist in particles generated in marine regions, around alkaline dry lakes, and in the Arctic snowpack. Although the photochemistry of nitrate ions in bulk aqueous solution is well known, there is recent evidence that it may be more efficient at liquid-gas interfaces, and ...

Effect of the Fast Pyrolysis Temperature on the Primary and Secondary Products of Lignin

11.09.2013 | Shuai Zhou; Manuel Garcia-Perez; Brennan Pecha; Sascha R. A. Kersten; Armando G. McDonald; Roel J. M. Westerhof, Energy & Fuels, 2013

This paper presents results on the primary pyrolysis products of organosolv lignin at temperatures between 360 and 700 °C. To study the primary products, a vacuum screen heater (heating rate of 8000 °C/s, deep vacuum of 0.7 mbar, and very fast cooling at the wall temperature of −100 °C) was used. ...

Functionality of Protein‐Fortified Extrudates

10.09.2013 | Li Day, Barry G. Swanson, Comprehensive Reviews in Food Science and Food Safety, 2013

Abstract Fortification of extrusion feed formulations with proteins from selected sources will improve the health‐promoting quality of snack and breakfast foods. Molecular interactions among proteins, starch, lipids, water, and other constituents in the extrusion “melt” are the basis for ...

Potential of water hyacinth for phytoremediation in low temperature environment

10.09.2013 | Xue Wang, Lisa Shi, Christopher Q. Lan, Robert Delatolla, Zisheng Zhang, Environmental Progress, 2013

Water hyacinth, i.e., Eichhornia crassipes Solms can remove a large variety of different pollutants from water and are considered an excellent candidate for phytoremediation of contaminated waters. Nevertheless, exploitation of water hyacinth for phytoremediation has so far been limited to ...
