Asbestos in playground mulch—how to avoid a repeat of this circular economy scandal
Asbestos has been found in mulch used for playgrounds, schools, parks and gardens across Sydney and Melbourne. Local communities naturally fear for the health of their loved ones. Exposure to asbestos is a serious health risk—depending on its inten.....»»
Self-embedding silver nanoparticles: Researchers find the "silver lining" in cotton gin waste
Cotton gin waste, also known as cotton gin trash, is a byproduct of the cotton ginning process and occurs when the cotton fibers are separated from the seed boll. For cotton gin waste, the treasure is its hidden potential to transform silver ions int.....»»
Physicists track how continuous changes in dimensionality affect collective properties of a superfluid
An international research team from Innsbruck and Geneva has, for the first time, probed the dimensional crossover for ultracold quantum matter. In the regime between one and two dimensions, the quantum particles perceive their world as being 1D or 2.....»»
