Even before the UN Ocean Conference in early June, we already knew about the disastrous ways in which plastic affects the world’s oceans. Billions of pieces of plastic are floating in the oceans. Their effects are also sufficiently well-known: marine animals swallow them or get tangled up in them, which causes them to die in…
A Magic Hood for Artificial Pumps
Affordable Detectors for Gamma Radiation
A research team at Empa and ETH Zurich has developed single crystals made of lead halide perovskites, which are able to gage radioactive radiation with high precision. Initial experiments have shown that these crystals, which can be manufactured from aqueous solutions or low-priced solvents, work just as well as conventional cadmium telluride semi-conductors, which are…
