Chemists introduce new copper-catalyzed C-H activation strategy
Inspired by what human liver enzymes can do, Scripps Research chemists have developed a new set of copper-catalyzed organic synthesis reactions for building and modifying pharmaceuticals and other molecules. The new reactions are expected to be widel.....»»
Scientists explore the strategies of defects and nanostructure fabrication for promoting piezocatalytic activity
As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. B.....»»
Drawing a line back to the origin of life: Graphitization could provide simplicity scientists are looking for
Scientists in Cambridge University suggest molecules, vital to the development of life, could have formed from a process known as graphitization. Once verified in the laboratory, it could allow us to try and recreate plausible conditions for life's e.....»»
Researchers crack mystery of swirling vortexes in egg cells
Egg cells are the largest single cells on the planet. Their size—often several to hundreds of times the size of a typical cell—allows them to grow into entire organisms, but it also makes it difficult to transport nutrients and other molecules ar.....»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Researchers create nanomembrane to increase reaction rate in chemical production
Flow-through reactors packed with enzymes can produce certain chemicals in a gentle and careful way. However, their performance has so far been limited. A research team from the Helmholtz-Zentrum Hereon and RWTH Aachen University has now been able to.....»»
NASA"s Roman space telescope"s "eyes" pass first vision test
Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA's Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct.....»»
