Exceptional advances in the control of material properties has been achieved, through careful manipulation of geometry on nano- and sub-nanometre length scales, in magnetoelectronics and nanomagnetism.1 Advanced techniques now allow for the creation of structures patterned on sub-micron length scales in three dimensions. New phenomena has been discovered in patterned magnets that can be strongly controlled by ion bombardment, multilayering, and lithographic patterning.

Collecting energy from environmental waste heat such as that lost from the human body is an attractive prospect to power small electronics sustainably. A thermocell is a type of energy-harvesting device that converts environmental heat into electricity through the thermal charging effect.
