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 ...

Fishermen blast premier dive sites off Indonesia

(AP) -- Coral gardens that were among Asia's most spectacular, teeming with colorful sea life just a few months ago, have been transformed into desolate gray moonscapes by fishermen who use explosives or cyanide to kill ...

The presence of water changes the structure of an antibiotic

EPFL chemists have shown how the three-dimensional shape of an antibiotic changes when it is in an aqueous environment. This could lead to a better understanding of how drugs interact with biological molecules.

Researchers develop method to fingerprint air pollution

A team of researchers from the University of Pittsburgh and the Electric Power Research Institute (EPRI) collected emissions samples from several power plant stacks in the United States and developed a unique method for detecting ...

New motor can cut space exploration costs

(Phys.org) -- A European team of researchers led by the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland has developed a prototype of a new, ultra-compact motor that will enable small satellites to ...

In a small-device world, bigger may still be better

In the early days, standard computers could be as large as a single story house. Over the last several decades, many development efforts have focused on shrinking them for use in the home and eventually anywhere in the world ...
