Gold 'micro jewels' from the 3-D printer

Thanks to a laser technique that ejects ultra-tiny droplets of metal, it is now possible to print 3-D metal structures—not only simple 'piles' of droplets, but complex overhanging structures, as well, like a helix measuring ...

Scientists revisit optical constants of ultrathin gold films

Researchers at MIPT have conducted highly precise measurements of the optical constants of ultrathin gold films with thicknesses ranging from 20 to 200 billionths of a meter in the optical part of the electromagnetic spectrum. ...

Device design allows ten-fold increase in spin currents

An electron carries electrical charge and spin that gives rise to a magnetic moment and can therefore interact with external magnetic fields. Conventional electronics are based on the charge of the electron. The emerging ...

A giant leap to commercialization of polymer solar cell (PSC)

Researchers from Ulsan National Institute of Science and Technology (UNIST) have demonstrated high-performance polymer solar cells (PSCs) with power conversion efficiency (PCE) of 8.92% which is the highest values reported ...

Less wear, longer life for memory storage device

Probe storage devices read and write data by making nanoscale marks on a surface through physical contact. The technology may one day extend the data density limits of conventional magnetic and optical storage, but current ...
