For the first time, monolayers of transition metal dichalcogenides with excellent optical properties were grown. A team of physicists from the University of Warsaw managed to overcome the technical difficulties faced by industry and scientists from around the world, namely the very limited size, heterogeneity, and broadening of the spectralContinue Reading

Earlier this week (February 18), the US Department of Agriculture replaced on its website the animal welfare records that the agency had removed in early 2017 and added records that had been generated since, as ordered by Congress, The Washington Post reports.

An unexpected property of nanometer-scale antimony crystals — the spontaneous formation of hollow structures — could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more powerContinue Reading
