Self-charging biosupercapacitors (BSCs) that can store energy and be self-charged via chemical or solar energy conversion through bioreaction have recently attracted considerable attention. As human sweat also contains a high concentration of lactate biofuel, the harvesting and storage of the bioenergy in sweat holds the potential to provide the power for wearable electronics. A new wearable hybrid device functions as both a biofuel cell and a supercapacitor.
'Heavy fermions' are an appealing theoretical way to produce quantum entangled phenomena, but until recently have been observed mostly in dangerously radioactive compounds. A new study shows it is possible to make heavy fermions in subtly modified graphene, which is much cheaper and safer.
Researchers have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing.
