Researchers discover a new theory that paves the way for the design of better graphene electronics and energy converters.
Read morePicoscience and a plethora of new materials
The revolutionary tech discoveries of the next few decades may come from new materials so small they make nanomaterials look like lumpy behemoths. These materials will be designed and refined at the picometer scale, which is a thousand times smaller than a nanometer. A new study moves picoscience in a new direction: taking elements from the periodic table and tinkering with them at the subatomic level to tease out new materials.
Read moreThe fast dance of electron spins
Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role. Researchers succeeded in simulating the extremely fast spin flip processes that are triggered by the light absorption of metal complexes.

Scientists analyze the current graphene landscape and market forecast for graphene over the following decade.
Read morePrinted electronics open way for electrified tattoos and personalized biosensors
Electrical engineers have devised a fully print-in-place technique for printable electronics that is gentle enough to work on delicate surfaces ranging from paper to human skin. This can be accomplished without additional steps to bake, wash or powder-coat materials. The advance could enable technologies such as high-adhesion, embedded electronic tattoos and bandages with patient-specific biosensors.

A research team has invented a semiconductor quantum well system that can efficiently cool electronic devices using established fabrication methods. This work can allow for smaller and faster smart devices that consume less power.
Read moreInventing the world's strongest silver
A team of scientists has made the strongest silver ever — 42 percent stronger than the previous world record. It's part of a discovery of a new mechanism at the nanoscale that can create metals much stronger than any ever made before — while not losing electrical conductivity.
Read moreFinding the 'magic angle' to create a new superconductor
Researchers have made a discovery that could provide new insights into how superconductors might move energy more efficiently to power homes, industries and vehicles. Their work showed that graphene — a material composed of a single layer of carbon atoms — is more likely to become a superconductor than originally thought possible.
