I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Light shines on chemical production method” The picture illustrates the redox potential controlled selective oxidation of styrenes for regio- and stereoselective crossed intermolecular [2 2] cycloaddition via organophotoredox catalysis. Credit: Yujiro Hoshino, Yokohama National University A team of researchers from Japan has demonstrated a light-based reaction that yields high numbers of the base chemical component…
“#Mathematical modeling reveals how chitinase, a molecular monorail, obeys a one-way sign” Fig. 1. (A) Trajectory of single-molecule motion and corresponding chemical-state-dependent free energy profiles. (B) Schematic of a hidden Markov model in which the chemical states are regarded as “hidden” states. Credit: NINS/IMS A novel mathematical modeling method has been developed to estimate operation…
“#Scientists identify new catalysts for more efficient water splitting” To improve the performance of spinel oxides, a deeper understanding of how they work as catalysts to make water electrolysis more efficient is needed. By identifying the parameters that make spinel oxides good catalysts for this process, the NTU-led team can now create new, better spinel…
“#New study sheds light on designing of heterogeneous catalysts for selective carbon dioxide photoreduction” Credit: WANG Ruihu’s group The use of covalent organic frameworks (COFs) as heterogeneous catalysts for photocatalytic CO2 reduction has attracted significant attention owing to their well-defined structure, high surface area and structural modularity. However, most COFs-based catalytic systems require the presence of…
“#New printing process advances 3-D capabilities” This tensile object was created using 3D injection printing, a new technology invented by UMass Lowell Plastics Engineering Prof. David Kazmer. Credit: David Kazmer More durable prosthetics and medical devices for patients and stronger parts for airplanes and automobiles are just some of the products that could be created…
“#Scientists discover new class of semiconducting entropy-stabilized materials” Crystal structure of GeSnPbSSeTe, a semiconducting entropy-stabilized chalcogenide alloy. The yellow atoms are cations (Ge, Sn, Pb) and the blue atoms are anions (S, Se, Te). The difference in lightness corresponds to different species of the anions and cations. The configurational entropy from the disorder of both…
“#Researchers find crystals of indium selenide have exceptional flexibility” Deformability of InSe single crystals. (A) Crystal structure of β-InSe and the projection on the (110) and (001) planes. (B) As-grown crystal and (C) cleavage surface. (D to F) InSe single crystal is morphed into various shapes without breaking. (G) Scanning electron microscopy (SEM) image of…
“#Nano-sponges of solid acid transform carbon dioxide to fuel and plastic waste to chemicals” Nano solid acids that transform carbon dioxide directly to fuel(dimethyl ether) and plastic waste into chemicals (hydrocarbons). Credit: Ayan Maity,TIFR, Mumbai The primary cause of climate change is atmospheric CO2, and levels are rising every day. There is, therefore, a great…
“#Challenging a central tenet of chemistry” Credit: CC0 Public Domain Steve Granick, Director of the IBS Center for Soft and Living Matter and Dr. Huan Wang, Senior Research Fellow, report together with 5 interdisciplinary colleagues in the July 31 issue of the journal Science that common chemical reactions accelerate Brownian diffusion by sending long-range ripples…
“#Team simultaneously synthesizes dicarboxylic acids and hydrogen from diols” Using an iridium catalyst bound to a bipyridonate ligand, researchers were able to synthesize dicarboxylic acids from aqueous diols, with the added benefit of generating hydrogen as a byproduct. Credit: Kyoto University Every year, the chemical industry makes trillions of dollars synthesizing the countless chemical compounds…
