carbon nanotubes

Self-healing circuits

Materials World magazine
Capsules placed on circuit boards that contain suspensions of conductive carbon nanotubes could make burnt out electronics a thing of the past. The shells are being designed to erode under conditions of high electrical potential, temperature spikes, mechanical damage or other appropriate stimuli.

At the core of sandwich composites

Materials World magazine
A novel interlayer between the skin and foam core in sandwich structures could provide composite components with an inherent self-healing mechanism. This reinstates the backface support to prevent buckling during compression.

Making light work of silicon chips

Materials World magazine
Silicon chips that can emit light could be demonstrated within four years, thanks to a team of international researchers who claim to have overcome previous limitations.
