I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#A new way of modulating color emissions from transparent films” A new study from Japan provides fresh insights into the creation of more efficient multicolor transparent luminescent materials. Credit: Tokyo University of Science Scientists are looking at luminescent transparent films for use in energy-efficient displays (such as LED screens) and other applications, and the possibilities…
“#Continuous and stable lasing achieved from low-cost perovskites at room temperature” A layer of perovskite is shown lasing green under continuous operation at room temperature. Research from Kyushu University and Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, indicates that suppressing triplet excitons is important for overcoming the lasing death phenomenon that has so…
“#For photocatalysts, standing the test of time means finding a perfect partner” Credit: Pixabay/CC0 Public Domain The key to efficiently harvesting energy from sunlight could be to find the right combinations of light-capturing materials. Researchers at KAUST have discovered that a form of iron oxide makes an excellent co-catalyst for a promising photocatalytic material called…
“#Can sunlight convert emissions into useful materials?” Credit: Pixabay/CC0 Public Domain Shaama Sharada calls carbon dioxide—the worst offender of global warming—a very stable, “very happy molecule.” She aims to change that. Recently published in the Journal of Physical Chemistry A, Sharada and a team of researchers at the USC Viterbi School of Engineering seek to…
“#Additive manufacturing of multi-functional parts” System for Multi Material Jetting of high-performance components with combined properties or functions. Credit: Fraunhofer IKTS Additive manufacturing is currently one of the most significant trends in industry. Now a team from the Fraunhofer Institute for Ceramic Technologies and Systems IKTS has developed a Multi Material Jetting system that allows…
“#Scientists reveal secret of material for promising infrared cameras” Bolometer. Credit: Daria Sokol/MIPT Researchers from the Moscow Institute of Physics and Technology and the RAS Institute for Theoretical and Applied Electromagnetics have discovered what makes vanadium dioxide films conduct electricity. Published in Physical Review B, their findings will enable thermal imaging devices with a sensitivity…
“#Researchers develop molecule to store solar energy” Bo Durbeej and his group use advanced computer simulations of chemical reactions, which are performed at the National Supercomputer Centre, NSC, in Linköping. Researchers at Linköping University, Sweden, have developed a molecule that absorbs energy from sunlight and stores it in chemical bonds. A possible long-term use of…
“#Manganese single-atom catalyst boosts performance of electrochemical carbon dioxide reduction” Schematic diagram of Mn SAC preparation and mechanism of electrochemical CO2 reduction. Credit: FENG jiaqi Electrochemical CO2 reduction reaction (CO2RR) is a promising approach to convert CO2 into useful chemicals. A research team led by Prof. Zhang Suojiang from the Institute of Process Engineering (IPE)…
“#Cool touch shirts can make you feel cool on hot days, but which materials work best?” The face (left) and back (right) sides of a jersey knit material have different effusivity properties. Credit: Jeremy Stangeland, CC BY-ND It’s another hot and sweaty summer day, and you see an ad for a sports T-shirt claiming it…
“#A new strategy for the electrochemical reduction of nitrate to ammonia” Proposed structure of Cu-incorporated PTCDA and schematic diagram illustrating its advantage of selectively reducing NO3− into NH3 via direct 8-eletron transfer. Red, white, gray, brilliant-blue, and green spheres represent the O, H, C, Cu, and N atoms, respectively. Credit: Chen et al. Ammonia (NH3)…
