I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Hybrid nanomaterials hold promise for improved ceramic composites” Credit: CC0 Public Domain Researchers at Wright-Patterson Air Force Base are seeking to patent a novel process for manufacturing a type of material called preceramic polymer-grafted nanoparticles, or “hairy nanoparticles” (HNP). An HNP is a hybrid material consisting of a polymer shell bound to a solid nanoparticle…
“#2-D nanomaterial shows promise for high-speed electronics, quantum devices and defense tools” A Purdue University team received a U.S. patent for a nanomaterial derived from the rare element tellurium, which has a thin, durable structure with unique properties. Credit: Purdue University Purdue University researchers have passed another significant milestone as they work to take a…
“#Spin-galvanic effect in graphene with topological topping demonstrated” Credit: CC0 Public Domain Researchers at Chalmers University of Technology, Sweden, have demonstrated the spin-galvanic effect, which allows for the conversion of non-equilibrium spin density into a charge current. Here, by combining graphene with a topological insulator, the authors realize a gate-tunable spin-galvanic effect at room temperature….
“#Measuring adhesion and friction of polymer nanofibers” A polymer nanofiber, smaller than one hundredth the size of a human hair, mounted on a MEMS mechanical testing device. The inset shows two devices positioned perpendicularly so that adhesion and friction forces could be simultaneously measured at the intersecting point of contact. Credit: University of Illinois at…
“#Graphene additives show a new way to control the structure of organic crystals” Optical images of crystals obtained on substrates with different graphene coverages. Credit: University of Manchester A team of researchers at The University of Manchester has demonstrated that the surface properties of graphene can be used to control the structure of organic crystals…
“#New advancement in nanophotonics has the potential to improve light-based biosensors” Credit: University of New Mexico As COVID-19 swept across the world this year, claiming hundreds of thousands of lives, it quickly became clear that one essential factor for controlling its spread is the ability to rapidly and accurately test for the virus causing it,…
“#Scientists find direct evidence of thickening organic film at soil-water micro-interfaces” Credit: CC0 Public Domain Soil organic matter is essential for the maintenance of soil fertility, absorption of pollutants and mitigation of global climate change. In the past few decades, the long-term protection mechanism of organic matter in soil and sediment has been extensively studied….
“#An improved wearable, stretchable gas sensor using nanocomposites” An example of a flexible gas sensor worn over a knuckle. Credit: Cheng Lab, Penn State A stretchable, wearable gas sensor for environmental sensing has been developed and tested by researchers at Penn State, Northeastern University and five universities in China. The sensor combines a newly developed…
“#New tech extracts potential to identify quality graphene cheaper and faster” Credit: CC0 Public Domain Engineers at Australia’s Monash University have developed world-first technology that can help industry identify and export high quality graphene cheaper, faster and more accurately than current methods. Published today in international journal Advanced Science, researchers used the data set of…
“#Sandwich catalysts offer higher activity and durability” Credit: Pohang University of Science & Technology (POSTECH) The sandwich is a food concocted by the 18th-centutry nobles to play card games uninterrupted. Meat or vegetables were layered then tucked between bread to be eaten quickly while engaged in the game. This efficient food also delivered ample calories…
