I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#An environmentally friendly way to transform silicon into nanoparticles” Credit: Skolkovo Institute of Science and Technology Skoltech scientists and their colleagues from Lomonosov Moscow State University (MSU) have developed a new method of silicon recycling. Their research was published in ACS Sustainable Chemistry & Engineering. The majority of solar panels that are produced in ever-increasing…
“#Efficient removal of steroid hormones from water” Filtration systems with the semipermeable membrane (Ultrafiltration – UF) and a layer of activated carbon (polymer-based spherical activated carbon – PBSAC). Credit: IAMT/KIT Micropollutants contaminate the water worldwide. Among them are steroid hormones that cannot be eliminated efficiently by conventional processes. Researchers of Karlsruhe Institute of Technology (KIT)…
“#Time for a new contender in energy conversion and storage” The KAUST team used state-of-the-art evolutionary search and first-principles calculations to predict the structure of B2P6. Credit: KAUST Evolutionary search has helped scientists predict the lowest energy structure of a two-dimensional (2-D) material, B2P6, with some remarkable features, including structural anisotropy and Janus geometry. Janus…
“#Splitting water molecules for a renewable energy future” Chemistry graduate student Zhijie Yang is operating synchrotron measurement computer at Advanced Photon Source of the Argonne National Lab in a photo taken before the COVID-19 pandemic. Credit: Virginia Tech The future economy based on renewable and sustainable energy sources might utilize battery-powered cars, large-scale solar and…
“#A green catalyst for pharmaceutical and industrial chemistry” Many production facilities (e.g. plastic manufacturers, pharma companies, and others) use nanocatalysts that contain palladium–an expensive component that is not sustainably produced. A chemist from RUDN University found a way to reduce palladium consumption and to make its manufacture more eco-friendly. He developed a catalyst based on…
“#A novel betavoltaic technology with dyes for better energy production” The diagram shows the inside of a betavoltaic cell and explains the flow of electrons inside the battery. Credit: DGIST/Royal Society of Chemistry Electronic devices are becoming smaller, more connected, and more powerful; and they still have one thing in common: they need energy to…
“#Wool-like material can remember and change shape” A keratin sheet folded into a complex origami star as its permanent shape. Credit: Luca Cera/Harvard SEAS As anyone who has ever straightened their hair knows, water is the enemy. Hair painstakingly straightened by heat will bounce back into curls the minute it touches water. Why? Because hair…
“#Researchers develop low-cost, drop-on-demand printing technique” Drop impact printing setup with recycling unit. Credit: Nature Communications, Microfluidic Devices and Heterogeneous Systems Lab, CeNSE Researchers at the Center for Nano Science and Engineering (CeNSE), IISc, have developed a low-cost, drop-on-demand printing technique capable of generating a wide range of droplet sizes using a variety of inks….
“#Making more of methane” Global natural gas production over years. Credit: © 2020 data from the International Energy Agency (IEA) Demand continues for plastics and solvents made from petrochemicals, which are mainly produced by refining oil despite diminishing global oil reserves, driving forward the search for new ways to produce the chemicals we need. Methane…
“#Strong fields and ultrafast motions—how to generate and steer electrons in liquid water” (a) Snapshot of the arrangement of water molecules in the liquid (red: oxygen atoms, grey; hydrogen atoms). The dotted lines indicate hydrogen bonds between the molecules. Each water molecule possesses an electric dipole moment d which generates an electric field in its…
