Lithium-sulfur batteries last longer with nanomaterial-packed cathode
Electric vehicles could travel farther and more renewable energy could be stored with lithium-sulfur batteries that use a unique powdery nanomaterial.
Researchers model world's first carbon-based 'spaser'
(Phys.org) —A new version of "spaser" technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.
First direct observations of excitons in motion achieved
A quasiparticle called an exciton—responsible for the transfer of energy within devices such as solar cells, LEDs, and semiconductor circuits—has been understood theoretically for decades. But exciton ...
Physicists create new nanoparticle for cancer therapy
A University of Texas at Arlington physicist working to create a luminescent nanoparticle to use in security-related radiation detection may have instead happened upon an advance in photodynamic cancer therapy.
Making 'bucky-balls' in spin-out's sights
(Phys.org) —A new Oxford spin-out firm is targeting the difficult challenge of manufacturing fullerenes, known as 'bucky-balls' because of their spherical shape, a type of carbon nanomaterial which, like ...
New sensor improves the level of efficiency in detecting ozone
Researchers from the Universitat Jaume I in Castelló, the São Paulo State University in Brasil and the Aix-Marseille University in France have developed a more effective ozone sensor than the ones used ...
New type of barcode could make counterfeiters' lives more difficult
Counterfeiters, beware! Scientists are reporting the development of a new type of inexpensive barcode that, when added to documents or currency, could foil attempts at making forgeries. Although the tags ...
Solar cells made from polar nanocrystal inks show promising early performance
Chemists design nanoparticles that can deliver three cancer drugs at a time
Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. In recent years, scientists have developed nanoparticles that deliver one or ...
Using strong lasers, investigators observe frenzy of electrons in a new material
(Phys.org) —A research team at the University of Kansas has used high-powered lasers to track the speed and movement of electrons inside an innovative material that is just one atom thick. Their findings ...
