I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Physicists discover new two-dimensional material” Credit: CC0 Public Domain University of Arkansas scientists are part of an international team that has discovered a two-dimensional ferroelectric material just two atoms thick. Two-dimensional materials are ultrathin membranes that hold promise for novel optoelectronic, thermal, and mechanical applications, including ultra-thin data-storage devices that would be both foldable and…
“#Beyond chip-and-PIN: Graphene’s quick, hygienic solution to restaurant payment” Credit: University of Manchester A new graphene-based contactless payment system, developed in collaboration with the University of Manchester, has begun a restaurant pilot that could pave the way for the end of chip-and-PIN, cutting customer wait-time and reducing the risk of infectious transmission. Payper allows the…
“#Machine learning peeks into nano-aquariums” The schematic shows a simplified version of the steps taken by researchers to connect liquid-phase electron microscopy and machine learning to produce a streamlined data output that is less tedious to process than past methods.

“#Researchers shed light on the building blocks for next-generation LED displays” Before returning to China to earn his Ph.D., Jun Yi was a student researcher at Clemson University. Credit: College of Science Three teams of researchers at Clemson University have joined forces to unravel some of the mysteries surrounding perovskite nanocrystals, which are semiconductors with…
“#Breakthrough in blue quantum dot technology” Blue quantum dot solution glowing in a vial in a lab. Credit: Canadian Light Source There are many things quantum dots could do, but the most obvious place they could change our lives is to make the colors on our TVs and screens more pristine. Research using the Canadian…
“#A new two-dimensional carbon allotrope: Semiconducting diamane film synthesized” Pressure-induced graphene-diamane transition. Credit: Center for High Pressure Science & Technology Advanced Research Atomically thin diamond, also called diamane, is a two-dimensional carbon allotrope and has attracted considerable scientific interest due to its potential physical properties. However, previous studies suggest that atomically thin diamond films are…
“#Promising strategies to enhance separation selectivity of nanofiltration” Schematic diagram of strategies for enhancing selectivity of NF membranes (a-c) during membrane fabrication or (d-f) through function or process intensification.

“#Team makes case for high-performance carbon nanotube fibers for industry” The cross-section of a fiber produced at Rice University contains tens of millions of carbon nanotubes. The lab continually improves its method to make fibers, which tests show are now stronger than Kevlar. Credit: Pasquali Research Group Carbon nanotube fibers made at Rice University are…
“#Scientists develop approach to synthesize unconventional nanoalloys for electrocatalytic application” Credit: CC0 Public Domain Metallic alloys at the nanometer scale (nanoalloys) have great potential in electrocatalysis. The interaction among different components in nanoalloys may modify the electronic configurations of active metals and generate synergistic effects, boosting their performance in terms of activity, durability and selectivity…
