Salt Water System Could Generate Hydrogen

(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...

Graphite offers up new quantum surprise

Researchers at The University of Manchester in the UK, led by Dr. Artem Mishchenko, Prof Volodya Fal'ko and Prof Andre Geim, have discovered the quantum Hall effect in bulk graphite—a layered crystal consisting of stacked ...

Can graphene nanoribbons replace silicon?

(PhysOrg.com) -- "Graphene has been the subject of intense focus and research for a few years now," Philip Kim tells PhysOrg.com. "There are researchers that feel that it is possible that graphene could replace silicon as ...

How a thin-film copper sandwich is transforming electronics

As devices get smaller and more powerful, the risk of them overheating and burning out increases substantially. Despite advancements in cooling solutions, the interface between an electronic chip and its cooling system has ...

Quantum dot LEDs get brighter, more efficient

(Phys.org) -- While quantum dot-based light-emitting diodes (QLEDs) are not made of organic materials, they share many of the same advantages as organic LEDs (OLEDs). For instance, both QLEDs and OLEDs outshine semiconductor-based ...
