We investigated the impact of disposable plastic facemasks (DPFs) on environment. * Micro and nano particles emitted from DPFs were deposited on Al 2O 3 membranes. * Particles emitted from DPFs were identified as silicon-based and plastic fibres. * Leachate was analysed using mass spectrometry for heavy metals and polar organics.

News: Scientists at a Spanish university are developing a new type of concrete that captures rainwater to create living walls of moss and fungi. Unlike existing vertical garden systems which require complex supporting structures, the new "biological concrete" supports the growth of organisms on its own surface, according to researchers from Universitat Politècnica de Catalunya in Barcelona.

Mourou was the co-recipient of his Nobel with Donna Strickland for their development of Chirped Pulse Amplification (CPA) at the University of Rochester. In his speech, he referred to his "passion for extreme light."CPA produces high-intensity, super-short optical pulses that pack a tremendous amoun...

London is the latest city to gain a city bench with the ability to absorb as much pollution as a small forest. The vertical garden, which doubles as a bench, is Green City Solutions' CityTree. Using a vertical installation of moss, the bench can absorb as much pollution as 275 trees in 1 percent of the space.
