I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Mineral undergoes self-healing of irradiation damage” Tabular monazite on a xenotime crystal. Königsalm near Senftenberg, Lower Austria. Credit: Martin Slama Several minerals suffer radioactive self-irradiation and experience long-term changes to their properties. The mineral monazite behaves like Camembert cheese in which holes are drilled: existing radiation damage heals itself. An international research team led by…
“#Novel photocatalysts can perform solar-driven conversion of carbon dioxide into fuel” Adopting the photocatalytic conversion of CO2 into fuel in high-emission facilities would be highly beneficial to both the environment and the economy. Credit: Shutterstock Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, develop a novel “heterostructured” photocatalyst using titanium and copper, two…
“#New process boosts lignin bio-oil as a next-generation fuel” Trees are a source of cellulose, hemicelluloses, and lignin. A new process for upgrading lignin bio-oil to hydrocarbons could help expand use of the lignin, which is now largely a waste product left over from the productions of cellulose and bioethanol.

“#Scientists probe the chemistry of a single battery electrode particle both inside and out” A simulation based on X-ray experiments at SLAC shows what happens to a single battery electrode particle when it is charged over the course of 12 minutes. The particle swells and shrinks as lithium ions enter and leave, causing the particle…
“#Cascades with carbon dioxide” Credit: Angewandte Chemie Carbon dioxide (CO2) is not just an undesirable greenhouse gas, it is also an interesting source of raw materials that are valuable and can be recycled sustainably. In the journal Angewandte Chemie, Spanish researchers have now introduced a novel catalytic process for converting CO2 into valuable chemical intermediates…
“#Boundaries no barrier for thermoelectricity” A scanning electron microscope image shows a single-crystal gold nanowire on a thermal oxide substrate. Rice University scientists showed that strain and defects in the material can change its thermoelectric response.

“#Bio-based resin: A breakthrough in rapid prototyping” A universal bio-based resin developed by KTU researchers can be used for a multi-scale 3D printing. Up to now, no single resin was developed which would allow manufacturing of ultra-fine nano-/micro-features and macro-objects out of the same composition.

“#Theoretical prediction of reverse intersystem crossing for organic semiconductors” Credit: CC0 Public Domain A joint research team at RIKEN and Hokkaido University developed a method to predict rate constants of reverse intersystem crossing (RISC)associated with light emission efficiency of organic semiconductors used for organic light-emitting diodes (OLEDs) through quantum chemical calculations with computers. Thermally activated…
“#The new composite prevents malfunctions of electronic devices” Credit: pixabay.com Scientists from South Ural State University, in collaboration with colleagues from Belarus, India and China, have created a composite material for nanoelectronics. The material can be used as a dielectric (insulating substance) in polymer capacitors. These devices store energy and may be used in the…
“#Producing leather-like materials from fungi” Credit: Pixabay/CC0 Public Domain Traditional leather and its alternatives are typically obtained from animals and synthetic polymers. Leather can be considered a co-product of meat production with both livestock farming and the leather production process increasingly considered to be ethically questionable and environmentally unfriendly (e.g. deforestation for grazing, greenhouse gas…
