Self-folding materials pop-up at a stretch

mechanically-triggered origami-inspired approach creates complex three-dimensional structures for biomedicine, electronics or robotics

Researchers have replaced the expensive metals and traditional liquid electrolyte in lithium-ion batteries with iron fluoride and a solid polymer.

Imperfections and electrochemically driven silicon-lithium alloying reactions allow a new silicon-based metamaterial to deform to order.

Researchers have used computational techniques to identify 43 previously unknown forms of carbon that are thought to be stable and superhard.

By taking advantage of the nanomaterial graphene, scientists have developed the smallest ever accelerometer for measuring acceleration.

A novel de-icing technique uses an electric pulse to melt the ice where the surface and the ice meet, so the ice can simply slide off.

Graphene can provide a two-fold defense against mosquito bites, by acting as a physical barrier and blocking chemical signals.

Researchers have developed a mathematical framework that can turn any sheet of material into any prescribed shape, using the paper craft kirigami.

Engineers have developed a transistor made from linen thread, by coating the thread in carbon nanotubes and immersing it in an electrolyte gel.

Electronic robotic skin device sends information back to the user

Researchers have found that better graphene oxide (GO) ‘paper’ can be made by mixing strong, solid GO flakes with weak, porous GO flakes.
