Lithium-ion batteries that last longer in extreme cold

When temperatures fall below freezing, cellphones need to be recharged frequently, and electric cars have shorter driving ranges. This is because their lithium-ion batteries' anodes get sluggish, holding less charge and draining ...

Ink coating could enable devices powered by heat

Researchers in Sweden report that they are closing in on a way to replace batteries for wearables and low-power applications in the internet of things (IoT). The answer lies in an ink coating that enables low-grade heat, ...

Geometrically engineered rigid island array for stretchable electronics

Stretchable electronics can be developed by integrating rigid components in a soft polymer matrix. However, it is challenging to eliminate cracks at the interface between soft and rigid materials. In a new report now published ...

Logical switching using one single molecule

Logic gates, the basic elements of the digital world, can now be built using one single molecule. An example is XOR, with two inputs. If at least one of them is "1," then the output is "1," as well; otherwise, it is 0. These ...
