I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Li-ions transport across electrolytes and SEI” Credit: CC0 Public Domain The kinetics of Li-ions transport across the electrolyte and the SEI is usually the rate-determining step in the Li plating-stripping process. Before electroplating on the anode surface, Li-ions migrate from a cathode to an anode through pores in a separator that is filled with electrolytes….
“#New material can generate hydrogen from salt and polluted water” Credit: Tomsk Polytechnic University Scientists of Tomsk Polytechnic University jointly with teams from the University of Chemistry and Technology, Prague and Jan Evangelista Purkyne University in Ústí nad Labem have developed a new 2-D material to produce hydrogen, which is the basis of alternative energy….
“#High-performance large area electrode system developed for artificial photosynthesis” (Right) Coral shape silver nano-catalyst electrode with high-performance, large-area developed by KIST researchers (electrode size 50 cm) (Left) Catalyst electrode for synthetic photosynthesis in existing gas state (electrode size 2cm) Credit: Korea Institue of Science and Technology(KIST) A research team, led by Dr. Hyung-Suk Oh and…
“#Physicists take stop-action images of light-driven molecular reaction” This illustration shows the light-induced ring opening reaction across multiple femtoseconds. This work by Kansas State University researchers has just been published in Nature Chemistry. Credit: Lea-Maria Ibele Kansas State University physicists have taken extremely fast snapshots of light-induced molecular ring-opening reactions—similar to those that help a human…
“#Shells and grapefruits inspire first manufactured non-cuttable material” Credit: CC0 Public Domain Engineers have taken their inspiration from shells and grapefruits to create what they say is the first manufactured non-cuttable material. This new material, which could be used in the security and health and safety industries, can turn back the force of a cutting…
“#Q&A: Toward a new way of producing solar cells” Credit: University of Luxembourg Physicists from the University of Luxembourg together with international scientists have investigated the oxidation process of solar cell materials whose results could change the current way of producing solar cells. The study has been published in the renowned journal Nature Communications in…
“#Self-emitted surface corrugations in dynamic fracture of silicon single crystal” Dynamic crack front behavior in steady-state (110) cleavage of the single crystalline silicon samples under pure bending. (A) Morphologies of the (110) cleavage plane (xy plane) of the as-sawn samples at different steady-state crack propagation speeds vs. The crack propagates along the [110] direction (x…
“#Single nanoparticles could pave the way for medicines on demand” We can now ‘see’ the twist of a single nanoparticle, floating freely in a liquid. Credit: Ventsislav Valev and Joel Collins For the first time, a single, twisted nanoparticle has been accurately measured and characterised in a lab, taking scientists one vital step closer to…
“#Enhanced water repellent surfaces discovered in nature” New discoveries about the nanostructure of insects, such as the eye of a mosquito, could help engineer enhanced water repellent coatings. Credit: Ling Wang, Penn State Through the investigation of insect surfaces, Penn State researchers have detailed a previously unidentified nanostructure that can be used to engineer stronger,…
“#New explosive materials to bring nontoxic ammunition” Matthew Gettings, a Purdue Ph.D. candidate, holds a cup containing silver salts, a new lead-free explosive. Credit: Purdue University photo/Jared Pike Every time a gun fires, lead leaches into the air. A scientific advancement could provide a comparable replacement for lead-based explosive materials found in ammunition, protecting soldiers…
