I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Fuel cells for hydrogen vehicles are becoming longer lasting” The new electrocatalyst for hydrogen fuel cells consists of a thin platinum-cobalt alloy network and, unlike the catalysts commonly used today, does not require a carbon carrier. Credit: Gustav Sievers Roughly 1 billion cars and trucks zoom about the world’s roadways. Only a few run on…
“#Study offers new insights for sun-gathering technologies” Cover of ACS Applied Energy Materials depicting a catalyst-modified solar cell producing hydrogen fuel under varying lighting conditions. Credit: Graphic by Jason Drees Every hour, the sun saturates the earth with more energy than humans use in a year. Harnessing some of this energy to meet global demand…
“#A leap forward for biomaterials design using AI” Artificial neural network model used in this work Credit: ACS Biomaterials Science & Engineering Researchers at Tokyo Institute of Technology (Tokyo Tech) have used artificial intelligence (AI) to predict the degree of water repulsion and protein adsorption by ultra-thin organic materials. By enabling accurate predictions of water…
“#’All-in-one’ strategy for metalla[3]catenanes, Borromean rings and ring-in-ring complex” Various interlocked structures: monomeric rectangle; ring-in-ring complex; Borromean rings; [2]catenanes; linear [3]catenanes. Credit: Science China Press Interlocked molecular species have received considerable attention recently, not only because of their intriguing structures and topological importance, but also because of their important applications as molecular machines and nanoscale…
“#Forest scientists develop innovative wood-based materials for 3-D printing” The biopaste used to print this cylinder consists of 50 percent lignin and 50 percent cellulose. Credit: Lisa Ebers A viscous biopaste that is easy to process, solidifies quickly and is suitable for producing even complex structures using the 3-D printing process has been developed by…
“#No more playing with fire: Study offers insight into ‘safer’ rechargeable batteries” Lithium dendrites deposited on the surface of carbon electrode are detected using nuclear magnetic resonance (NMR) analysis. The amount of lithium dendrite deposited is quantitively estimated from the 7Li NMR signal intensity. Credit: Reproduced from the inside-front cover picture (J. Mater. Chem. A,…
“#A new tool to create chemical complexity from fatty acids” The newly developed catalyst (center bottom) consists of a metal (iridium) atom at its core and various modules that ensure that the fatty acid amide or ester is precisely positioned in a way that the C-H bond located three carbons away from the carboxyl group…
“#Scientists invent new sensing eye mask” Announcing a soft new wearable eye mask for use in sleep and other studies, lead author Trisha Andrew at UMass Amherst says that recording health and behavior signals on or near the face is challenging because most people are really sensitive and reactive to objects placed on their face…
“#Scientists create water filtration membranes that can clean themselves” An artist’s rendition of light-induced self-cleaning of a fouled membrane. Credit: Argonne National Laboratory Scientists at the Department of Energy’s (DOE) Argonne National Laboratory have developed a light-activated coating for filtration membranes—the kind used in water treatment facilities, at semiconductor manufacturing sites and within the food…
“#Aerogel: The micro structural material of the future” To demonstrate that fine aerogel structures can be produced in 3D printing, the researchers printed a lotus flower made of aerogel. Credit: Empa Aerogel is an excellent thermal insulator. So far, however, it has mainly been used on a large scale, for example in environmental technology, in…
