Mess is best: disordered structure of battery-like devices improves performance
Mess is best: disordered structure of battery-like devices improves performance
The energy density of supercapacitors - battery-like devices that can charge in seconds or a few minutes - can be improved by increasing the 'messiness' of their internal structure. This could be a turning point for a field that's been stuck for a little while. Alex Forse Researchers led by the University of Cambridge used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors.

Scientists grow human mini-lungs as animal alternative for nanomaterial safety testing
Human mini-lungs grown by University of Manchester scientists mimic the response of animals when exposed to certain nanomaterials. The study at the University's NanoCell Biology Lab at the Centre for Nanotechnology in Medicine is published in the influential journal nanotoday . Though not expected to replace animal models completely, human organoids could soon lead to significant reductions in research animal numbers, the team led by cell biologist and nanotoxicologist Dr Sandra Vranic argues.
