Plasmid DNA can be used as a template to yield gold, palladium, silver, and chromium nanoparticles of different sizes based on variations in incubation time at 70 °C with gold phosphine complexes, with the acetates of silver or palladium, or chromium acetylacetonate. The employment of mild synthetic conditions, minimal procedural steps, and aqueous solvents makes this method environmentally gre...
A cleaner and greener method has been developed and used to synthesize 14 different functionalized oligomer derivatives of glycerol in moderate 29%-39% yields over three steps. After successive regioselective enzymatic acylation of the primary hydroxyl groups, etherification or esterification of the secondary hydroxyl groups and chemoselective enzymatic saponification, the target compounds can ...
0.05) in odor between treatments and the control BSP pieces for all storage days. Lactic acid treated BSP pieces were more likely to be lighter, greener, and more yellow throughout the storage period when compared to control BSP pieces. Lower microbial counts and indistinguishable odor differences were achieved with 2.00% LA treated BSP pieces. Using 2.00% LA in beef trimmings may provide a mic...
political science at Yale University, conducts research on institutional change, environmental politics, and development. His research has appeared in such journals as Comparative Political Studies, Development and Change, Journal of Asian Studies, Journal of Theoretical Politics, and World Development. His first book was Greener Pastures: Politics, Markets and Community among a Migrant Pastora...
Flow chemistry and continuous processing can offer many ways to make synthesis a more sustainable practice. These technologies help bridge the large gap between academic and industrial settings by often providing a more reproducible, scalable, safe and efficient option for performing chemical reactions. In this review, we use selected examples to demonstrate how continuous methods of synthesis ...
The development of lignocellulose-derived sustainable plastics is an important strategy for a greener future. Cellulosic hydrogels, which are readily generated from a cellulosic source (e.g., wood pulp), can be converted into high-strength plastics by hot-pressing. In this process, cellulose macromolecules are fluidized and reassembled, leading to significant change of bonding interactions and ...
The chemical industry plays a key role in sustaining the world economy and underpinning future technologies, yet is under unprecedented pressure from the effects of globalization and change in many of its traditional markets. Against this background, what will be needed for the industry to embrace efforts to make it "greener"? We explore some of the issues raised by the development of "green ch...
