New research explains Earth's peculiar chemical composition
Earth's surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes called "volatile" elements, or simply "volatiles," by geoscientists because many of the simple compounds they form are gases at standard temperature and pressure. However, the distribution of these vola New copper surface eliminates bacteria in just two minutes
A new copper surface that kills bacteria more than 100 times faster and more effectively than standard copper could help combat the growing threat of antibiotic-resistant superbugs.
The new copper product is the result of a collaborative research project with RMIT University and Australia's national science agency, CSIRO, with findings just published in Biomaterials.
