物质与能量When scientists examined pellets from recycled plastic collected in 13 countries they found hundreds of toxic chemicals, including pesticides and pharmaceuticals. Because of this, the scientists judge recycled plastics unfit for most purposes and a hinder
阅读全文物质与能量With Amazon aiming to make 10,000 deliveries with drones in Europe this year and Walmart planning to expand its drone delivery services to an additional 60,000 homes this year in the states, companies are investing more research and development funding in
阅读全文物质与能量A form of brain-inspired computing that exploits the intrinsic physical properties of a material to dramatically reduce energy use is now a step closer to reality, thanks to a new study led by UCL and Imperial College London researchers.
阅读全文物质与能量Sodium- and potassium-ion batteries are promising next-generation alternatives to the ubiquitous lithium-ion batteries (LIBs). However, their energy density still lags behind that of LIBs. To tackle this issue, researchers from Japan explored an innovativ
阅读全文物质与能量A floating, solar-powered device that can turn contaminated water or seawater into clean hydrogen fuel and purified water, anywhere in the world, has been developed by researchers.
阅读全文物质与能量物质与能量物质与能量A research team has developed a reversible, water-based glue that has good adhesion in the neutral pH range, but can be detached again in strongly acidic or alkaline environments. As the team writes in the journal Angewandte Chemie, the novel adh
阅读全文物质与能量A joint research team at KAIST developed an intravenous (IV) needle that softens upon insertion, minimizing risk of damage to blood vessels and tissues. Once used, it remains soft even at room temperature, preventing accidental needle stick injuries a
阅读全文物质与能量A scientific team has developed a new polyurethane production technique using CO2 to create new types of easily recyclable plastics. The study, published in the Journal of the American Chemistry Society (J.A.C.S.), could provide a solu
阅读全文物质与能量An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer's and Parkinson's Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone.
阅读全文物质与能量Artificial intelligence (AI) is on the rise. Until now, AI applications generally have "black box" character: How AI arrives at its results remains hidden. Prof. Dr. Jürgen Bajorath, a cheminformatics scientist at the University of Bonn, and his te
