I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Algorithm predicts the compositions of new materials” Credit: CC0 Public Domain A machine-learning algorithm that can predict the compositions of trend-defying new materials has been developed by RIKEN chemists1. It will be useful for finding materials for applications where there is a trade-off between two or more desirable properties. Artificial intelligence has great potential to…
“#Glass-like wood insulates heat, is tough, blocks UV and has wood-grain pattern” Engineers at the University of Maryland designed a transparent ceiling made of wood that highlights the natural woodgrain pattern. Credit: A. James Clark School of Engineering, University of Maryland Need light but want privacy? A new type of wood that’s transparent, tough, and…
“#New science behind biodegradable algae-based flip-flops” Commerical-quality biodegradable flip-flops. Credit: Stephen Mayfield, UC San Diego. As the world’s most popular shoe, flip-flops account for a troubling percentage of plastic waste that ends up in landfills, on seashores and in our oceans. Scientists at the University of California San Diego have spent years working to resolve…
“#Why shaving dulls even the sharpest of razors” Credit: Unsplash/CC0 Public Domain Razors, scalpels, and knives are commonly made from stainless steel, honed to a razor-sharp edge and coated with even harder materials such as diamond-like carbon. However, knives require regular sharpening, while razors are routinely replaced after cutting materials far softer than the blades…
“#’Roaming reactions’ study to shed new light on atmospheric molecules” Credit: CC0 Public Domain A detailed study of roaming reactions—where atoms of compounds split off and orbit other atoms to form unexpected new compounds—could enable scientists to make much more accurate predictions about molecules in the atmosphere, including models of climate change, urban pollution and…
“#Controlling ice formation on gradient wettability surfaces for high-performance bioinspired materials” Freeze-casting technique using copper surfaces with different wettability and the resulting scaffolds. SEM images were taken from the cross section of 1-cm height parallel to the cold surface. (A to D) When freezing on the homogeneously hydrophilic and hydrophobic copper substrates, the ice crystals…
“#Tellurium makes the difference” Professor Wolfgang Weigand from the german University of Jena shows unusual structures of tellurium compounds. Credit: Anne Günther/Uni Jena The periodic system contains 118 chemical elements. However, only a few of them, such as hydrogen, carbon, nitrogen, oxygen and silicon, are of major importance in our daily lives. But things become…
“#Fuel from disused tires” Credit: CC0 Public Domain Used tires pose a serious environmental risk owing to the damage that may be caused when they are stored in the environment. They are emerging in ever greater numbers from one year to the next in developed countries so revalorizing them is a subject that is attracting…
“#Chemists create the brightest-ever fluorescent materials” Glowing 3D-printed gyroids made with bright SMILES materials. Credit: Amar Flood By formulating positively charged fluorescent dyes into a new class of materials called small-molecule ionic isolation lattices (SMILES), a compound’s brilliant glow can be seamlessly transferred to a solid, crystalline state, researchers report August 6 in the journal…
“#A reaction using light and two transition-metal catalysts to make anilines” Credit: Unsplash/CC0 Public Domain A team of researchers from the University of Manchester and pharmaceutical company AstraZeneca has developed a reaction that uses light and two transition-metal catalysts to make anilines. In their paper published in the journal Nature, the group describes their process…
