What if circuits could be drawn like pencil marks, work on almost any surface, and then be erased and reused when no longer ...

What if electronic circuits could be created simply by drawing lines with a pencil on paper or leaves—and then immediately applied to soft robots or ...

Anode-free sodium metal batteries (AFSMBs) are promising next-generation energy storage systems due to their high energy density and low cost. Unlike traditional designs that include a hard carbon or ...

A new sodium-based battery material is highly stable, capable of recharging as quickly as a lithium-ion battery and might deliver more energy than current battery technologies. Scientists at the ...
