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 ...

Chocolate, tea or coffee with zinc could reduce oxidative stress

Ageing and a low life expectancy are caused, at least partly, by oxidative stress. A team of researchers led by Prof. Dr. Ivana Ivanovi-Burmazovi from the Chair of Bioinorganic Chemistry at Friedrich-Alexander-Universität ...

New fiber nanogenerators could lead to electric clothing

(PhysOrg.com) -- In research that gives literal meaning to the term "power suit," University of California, Berkeley, engineers have created energy-scavenging nanofibers that could one day be woven into clothing and textiles.

The next medical frontier: nano-surgery

(PhysOrg.com) -- Engineering professor's nanorobot could be performing non-invasive surgical procedures on patients with tumors within the next decade.

'Seeing' through paint

(PhysOrg.com) -- When light passes through materials that we consider opaque, such as paint, biological tissue, fabric and paper, it is scattered in such a complex way that an image does not come through. "It is possible ...

How to see through opaque materials

New experiments show that it's possible to focus light through opaque materials and detect objects hidden behind them, provided you know enough about the material.

High-efficiency zinc-air battery developed

Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts. The results, published in the ...

Dielectric film has refractive index close to air

Researchers from North Carolina State University have developed a dielectric film that has optical and electrical properties similar to air, but is strong enough to be incorporated into electronic and photonic devices - making ...
