I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Innovative treatment prevents spread of bacteria across metal surfaces” This image shows a peptide release test, with the increased purple color showing more peptides being released. Credit: Purdue University Researchers at Purdue University have developed a treatment to infuse a hardened metal surface with naturally occurring antimicrobial peptides. The Purdue team’s technology creates a hard…
“#Engineers work out why fallen leaves on train tracks are so slippery” Credit: Pixabay/CC0 Public Domain A team of engineers at the University of Sheffield has found an explanation for the extreme slipperiness of train tracks when leaves have fallen on them. In their paper published in Proceedings of the Royal Society A, the group…
“#How to mix old tires and building rubble to make sustainable roads” Credit: CC0 Public Domain Researchers have shown how a blend of old tires and building rubble could be used as a sustainable road-making material, in a zero-waste solution to boost recycling and support the circular economy. Construction, renovation and demolition account for about…
“#Scientists go the distance in electron transfer study” One common way cells move electrons is to shuttle them around on small protein electron carriers. This banner depicts a rendition of electron carrier proteins, with the electron carrying centers in red.

“#How clean water technologies could get a boost from X-ray synchrotrons” Credit: George Hodan/public domain The world needs clean water, and its need is only going to grow in the coming decades. Yet desalination and other water-purifying technologies are often expensive and require a lot of energy to run, making it that much harder to…
“#Rare glassy metal discovered during quest to improve battery performance” New research describes the evolution of nanostructural lithium atoms (blue) depositing onto an electrode (yellow) during the battery charging operation. Credit: University of California – San Diego Materials scientists studying recharging fundamentals made an astonishing discovery that could open the door to better batteries, faster…
“#Small but self-imposing: Titanium alters behavior of host lattice atoms” Titan, lord of the lattice. Credit: Daria Sokol, MIPT Researchers from MIPT and their colleagues from Ural Federal University have combined optical and acoustic approaches and found that incorporating titanium atoms into barium hexaferrite leads to an unexpected substructure forming in the crystal lattice. The…
“#Hydrogel mimics human brain with memorizing and forgetting ability” The hydrogel’s memorizing-forgetting behavior is achieved based on fast water uptake (swelling) at high temperature and slow water release (shrinking) at low temperature, which is enabled by dynamic bonds in the gel. The swelling part turns from transparent to opaque when cooled, enabling memory retrieval. Credit:…
“#A ‘corny’ solution to help fight the spread of the novel coronavirus” The distinctiveness of this hand sanitizer comes from its ethanol base. Ethanol is a plant-based renewable energy source — in the U.S primarily produced from corn — that is often mixed in with gasoline for vehicles. Credit: University of Missouri Inside the Mizzou…
“#Controlling streams of liquid metal at room temperature” When liquid metal is released into water, its high surface tension makes it form droplets — rather than streams. But when a low voltage is applied, the surface tension drops, allowing the liquid metal to stream out as hairlike filaments. Credit: Minyung Song, NC State University Researchers…
