I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Researchers produce low-cost hand sanitizer from waste” Credit: CC0 Public Domain A Tel Aviv University breakthrough allows, for the first time, a local production of ethanol—and hand sanitizer—based on plant and paper waste, using a novel lignin (a substance found in plants) degradation process. This revolutionary process could significantly reduce production costs and lead to…
“#Vacancy dynamics on CO-covered Pt(111) electrodes” Credit: CC0 Public Domain Platinum arguably is the most important electrocatalyst material, not only because it is the best single element catalyst in a variety of important electrocatalytic reactions but also due to its relatively high stability. However, in the corrosive environment of real electrocatalysis systems, such as fuel…
“#Water molecules are gold for nanocatalysis” Credit: CC0 Public Domain Nanocatalysts made of gold nanoparticles dispersed on metal oxides are very promising for the industrial, selective oxidation of compounds, including alcohols, into valuable chemicals. They show high catalytic activity, particularly in aqueous solution. A team of researchers from Ruhr-Universität Bochum (RUB) has been able to…
“#Heat smarter, not harder: How microwaves make catalytic reactions more efficient” Conventional heating versus microwave heating. Credit: Tokyo Institute of Technology Many reactions that we use to produce chemical compounds in food, medical, and industrial fields would not be feasible without the use of catalysts. A catalyst is a substance that, even in small quantities,…
“#Researchers create ‘decoy’ coatings that trick infrared cameras” The letters C-A-L appear cool even when the environment is hot. UC Berkeley engineers develop a decoy that fools infrared cameras into perceiving a designated temperature rather than the actual temperature of the object. Credit: Kechao Tang Light can sometimes play tricks on our eyes. If you…
“#Novel gas-capture approach advances nuclear fuel management” Separation of 85Kr from spent nuclear fuel by a highly selective metal organic framework. Credit: Mike Gipple/NETL Nuclear energy provides about 20 percent of the U.S. electricity supply, and over half of its carbon-free generating capacity. Operations of commercial nuclear reactors produce small quantities of spent fuel, which…
“#Photochromic bismuth complexes show great promise for optical memory elements” Credit: Pixabay/CC0 Public Domain Russian chemists have obtained a new photochromic complex composed of of bismuth (III) and viologen cations and used the new compound to create optical memory elements which were shown to be highly efficient and stable. The outcomes of the study may…
“#Researchers develop an optical fiber made of gel derived from marine algae” Edible, biocompatible and biodegradable, these fibers have potential for various medical applications. Credit: Eric Fujiwara An optical fiber made of agar has been produced at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil. This device is edible, biocompatible and…
“#Designing a freestanding, supercharged polypeptide proton-conducting membrane” E72 > DC_E108. Credit: Science Advances, doi: 10.1126/sciadv.abc0810″ width=”800″> Structure of anionic SUP, devices for proton conductivity measurements and performance of different SUPs in these devices. (A) Primary structure of SUPs engineered with various charge densities. (B) Fabrication protocol of protein films deposited on gold IDEs. (C) Impedance…
“#Researchers design a nanotechnology-based system that can transport methane at lower pressure and cost” Researchers from the University of Alicante’s Advanced Materials Laboratory have created an optimal, low-cost methane storage system. The team, led by UA Professor of Inorganic Chemistry Joaquín Silvestre, has used an MOF material (highly porous metal-organic framework). In the pores of…
