I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Researchers develop new materials for energy and sensing” Left: Scanning electron microscope image of film fragments. Right: Elemental mapping indicates that hybrid perovskite has been created: tetrachloro-1,2-benzoquinone (TCBQ) is incorporated with the perovskite, as chlorine (top) and iodine (bottom) are co-localized.

“#N-doped carbon encapsulated transition metal catalysts to optimize performance of zinc-air batteries” Fe@NCG was be prepared by pyrolyzing solvent-free formed Fechitosan chelates and additional small molecule nitrogen source urea. The formed catalyst exhibits bifunctional catalytic performance toward ORR and OER in alkaline medium and higher power density and superior charge-discharge durability in zinc-air battery. Credit:…
“#Pressure suppresses carrier trapping in 2-D halide perovskite” Fluorescence micrographs during compression and the PL intensity and contribution of the trapped states’ emission as a function of pressure. Credit: Center for High Pressure Science & Technology Advanced Research Two-dimensional (2-D) organic-inorganic halide perovskites are emerging materials for photovoltaic and optoelectronic applications due to their unique…
“#What if airplanes could repair their own damage?” Credit: Pixabay. Airplanes are behemoths of the sky; a commercial airliner is over 6,000 times as heavy as a large Canadian goose. At 500 mph, however, these behemoths are not impervious to impact, even from the seemingly innocuous goose. Such damage can result in a range of…
“#Antibacterial activewear? The claim is just as absurd as it sounds” Credit: Shutterstock Lorna Jane recently launched an “antiviral” line of its activewear, called “LJ Shield,” generating significant backlash from medical professionals. The popular activewear brand has now pedaled back and removed any mention of LJ Shield being antiviral from its marketing. But it still…
“#Researchers propose novel high-performance dual-ion batteries with 3-D porous structure” The formation of the LTO@3DC composite. Credit: SIAT Dual-ion batteries (DIBs) consisting of a graphite anode and cathode have attracted increasing attention due to their advantages of environmental friendliness, excellent cyclic stability and good safety. Lithium titanate (LTO) has emerged as a promising anode material…
“#Gel that breaks down, puts itself back together could improve delivery of oral drugs” An artistic rendering shows CAH degradation in response to pH changes over time that mimic the GI tract. The yellow dots represent the particles in the gel used to measure this process in microrheological experiments. Credit: Illustration by Sayo Studio LLC…
“#Tuning frontal polymerization for diverse material properties” The images illustrate the change in polymer shape depending on the glass transition temperature. Credit: the Autonomous Materials Systems Group. Researchers from the University of Illinois at Urbana-Champaign have improved the technique of frontal polymerization, where a small amount of heat triggers a moving reaction wave that produces…
“#Researchers create liquid-repelling substance that works on all surfaces” UBCO master’s student Behrooz Khatir measures liquid to be applied to an omniphobic film during testing inside the OPERA lab at UBC Okanagan’s School of Engineering. Credit: UBCO Acting like an invisible force field, a new liquid coating being developed by UBC Okanagan researchers may provide…
“#Graphene-adsorbate van der Waals bonding memory inspires ‘smart’ graphene sensors” (a) Adsorbed CO2 molecules on graphene sensor (b) van der Waals (vdW) interaction between adsorbed molecules and graphene at zero electric field (c) vdW interaction between adsorbed molecules and graphene with electric field.
