I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Preventing infection, facilitating healing: New biomaterials from spider silk” Scanning electron microscope images give overwhelming proof of the difference. Left: A biofilm forms on the surface of polycaprolactone, a biodegradable plastic frequently used in medicine. Right: Spider silk does not allow for biofilm formation. Credit: Gregor Lang. New biomaterials developed at the University of Bayreuth…
“#Laser writing of nitrogen-doped silicon carbide for biological modulation” Schematic illustrations of the laser writing process and its applications. (A) CO2 laser writing a pattern on a PDMS substrate wherein the pattern can be (i) on the surface, (ii) a trench, or (iii) a cut-through leading to the formation of two distinct pieces. Architectures (i)…
“#A novel salvinia-like slippery surface” Design of the Salvinia-like slippery surface. (a) Salvinia molesta floating leaf on which water drop displays stable Cassie state. Though the rational design of elastic eggbeater-shaped microstructure with surface energy gradient in vertical direction could stabilize the contact line to prevent impalement, such structure has strong adhesion because of the…
“#Self-assembly of responsive photonic biobased materials in liquid marbles” Credit: Wiley A surface displays structural colors when light is reflected by tiny, regular structural elements in a transparent material. Researchers have now developed a method to make structural colors from cellulose-based polymers by using coated droplets that exist in a surrounding fluid—so-called liquid marbles. The…
“#Researchers report new platform for stereocontrol” The overall transformation combining racemization of the ketone substrates (left) with biocatalytic reduction to enantiomerically pure alcohol products (center), and the key enaminyl radical species this chemistry unlocks to enable the racemization of typically static β-ketostereocenters (right).

“#Planetary ball-milling helps protect our planet from plastics pollution” Functions of the supramolecular materials. When the materials were wounded, they healed within 1 min. Further, when applied as a coating on a glass substrate, the material showed extremely fast healing properties, like skin. The recyclable property can treat severe damage which cannot be treated by…
“#Fish waste as a raw input for industrial goods” Research scientists Revilija Mozuraityte and Rasa Slizyte in the SINTEF lab, where they analyse oils, gelatin, and taste-neutral proteins derived from the rest raw materials left after salmon filleting. Credit: Håvard Egge The raw materials left after a salmon has been fileted are equivalent to more…
“#Thin-skinned solar panels printed with inkjet” The fully printed ultrathin solar cell is light and flexible enough to rest on the surface of a soap bubble. Credit: 2020 KAUST; Anastasia Serin Solar cells can now be made so thin, light and flexible that they can rest on a soap bubble. The new cells, which efficiently…
“#New Nitrogen-Assembly Carbon catalyst has potential to transform chemical manufacturing” A newly discovered metal-free carbon-based catalyst that has the potential to be much less expensive and more efficient for many industries, including manufacturing of bio- and fossil fuels, electrocatalysis, and fuel cells. Credit: U.S. Department of Energy, Ames Laboratory Scientists at the U.S. Department of…
“#Meteorite strikes may create unexpected form of silica” X-ray diffraction images showing the new form of silica created by sending an intense shock wave through a sample of quartz using a specialized gas gun. When the x-rays bounce off repeating planes of a crystalline structure, they scatter. This creates a distinctive ring pattern. Each ring…
