I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Removing toxic chemicals from water: New environmentally-friendly method” Credit: CC0 Public Domain Researchers from Swansea University have developed a new environmentally friendly method for removing toxic chemicals from water. A newly invented machine, called the Matrix Assembly Cluster Source (MACS), has been used to design a breakthrough water treatment method using a solvent-free approach. The…
“#Turning alcohol into key ingredients for new medicines” Scientists have found a way to turn alcohol into amino acids, crucial components of many medications. Credit: Unsplash Chemists have found a way to turn alcohol into amino acids, the building blocks of life. In a study published Monday in the journal Nature Chemistry, researchers explained the…
“#Nature-imitating coating makes batteries more durable and efficient” Carbon nanotubes coated with a coating using carbon dioxide in molecular layer deposition. Credit: Aalto University When batteries are charged and used, a complex SEI (solid electrolyte interphase) layer is formed. Its structure resembles a mosaic consisting of organic and inorganic parts assembled from several blocks. Researchers…
“#Polyimide membranes for the purification of natural gas” Credit: Wiley Natural gas that contains larger amounts of hydrogen sulfide (H2S) and carbon dioxide (CO2) is termed sour gas. Before it can enter a pipeline, it must be ‘sweetened’ by removal of its acidic impurities. Through fine tuning of the ratios of two molecular components, it…
“#An experiment suggested by a Ph.D. student may rewrite chemistry textbooks” Solvated electrons (green) in the gaps between ammonia molecules (blue and white) begin to coalesce into a pair as a solution moves toward becoming metallic. Credit: Ryan McMullen yan McMullen had never heard of the USC Dornsife College of Letters, Arts and Sciences when…
“#Team unveils catalyst that can break problematic C-F bonds” An artist’s illustration of the light-activated antenna-reactor catalyst Rice University engineers designed to break carbon-fluorine bonds in fluorocarbons. The aluminum portion of the particle (white and pink) captures energy from light (green), activating islands of palladium catalysts (red). In the inset, fluoromethane molecules (top) comprised of…
“#Extremely low thermal conductivity in 1-D soft chain structure” (a) The thermal conductivity as function of temperature. Insert is the chain structure of BiSeI. (b) The morphology of wire shape chains in 1D BiSeI. Credit: ©Science China Press Researchers have reported a new type of simple one-dimensional (1-D) crystal structured bismuth selenohalides (BiSeX, X =…
“#Highly modular metal-organic framework-based materials show great potential for photocatalytic hydrogen production” The metal-organic framework (gray and magenta lattice) can use solar energy to split water molecules (red and light blue spheres) to release hydrogen (light blue spheres). Credit: 2020 Nikita Kolobov A metal organic framework (MOF)-based water splitting photocatalyst, developed at KAUST, has brought…
“#’Robotic soft matter’ bends, rotates and crawls when hit with light” Northwestern University researchers have developed a family of soft materials that imitates living creatures. When hit with light, the film-thin materials come alive—bending, rotating and even crawling on surfaces. Called “robotic soft matter by the Northwestern team,” the materials move without complex hardware, hydraulics…
“#Preventing lithium loss for high-capacity lithium-ion batteries” Credit: Korea Institute of Science and Technology A team of Korean researchers has developed a processing technology for maximizing energy densities of high-capacity batteries. The joint research team, which consists of Dr. Minah Lee and Dr. Jihyun Hong of the Clean Energy Institute, Korea Institute of Science and…
