Quantum criticality observed in new class of materials

Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study, but the first findings of a 'quantum critical point' in a category of materials known as 'oxypnictides' could lead to a broader understanding of the quantum phenomenon.

Crystal nanoflowers and the future of architectural chemistry (w/video)

In this video, follow Harvard researchers Wim L. Noorduin and Joanna Aizenberg as they break down their process, showing how they developed these crystal 'flowers' using a beaker and two chemicals, manipulating the surrounding conditions to form them. Their research could potentially change our understanding of how structures are formed in nature, which may open the door for a new approach to nanotechnology.

2D transistors promise a faster electronics future

Faster electronic device architectures are in the offing with the unveiling of the world's first fully two-dimensional field-effect transistor (FET). Unlike conventional FETs made from silicon, these 2D FETs suffer no performance drop-off under high voltages and provide high electron mobility, even when scaled to a monolayer in thickness.
