Finding ways to extend a battery’s life starts with understanding why they degrade. Andrew Myers writing for Stanford University describes research there that is using new methods of high-resolution X-ray, electron and neutron microscopy to allow direct visualisation of battery materials at the nanoscale. Degradation is mostly caused by the expansion and contraction of the materials. The high resolution images are processed using AI to uncover … [Read more...]
Cement: replacing limestone with volcanic rock could slash energy use, and emissions by two-thirds
Cement production accounts for 8% of global emissions, and it will rise as nations get richer and build more. It’s mainly because of the energy needed for the high heat process, and the carbon released from the limestone used. It’s one of the leading hard-to-abate sectors, and coming up with an alternative process and cement recipe is firmly on the industry’s agenda. Josie Garthwaite at Stanford University summarises a study that aims to replace … [Read more...]
