Scientists at the U.S. Naval Research Laboratory (NRL) and the Air Force Research Laboratory (AFRL) have developed a way to directly write quantum light sources, which emit a single photon of light at a time, into monolayer semiconductors such as tungsten diselenide (WSe2). Single photon emitters (SPEs), or quantum emitters, are key components in a wide range of nascent quantum-based technologies, including computing, secure communications, sensing and metrology.

Nano drops explode 19th century theory

12.02. 2019 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Droplets emanating from a molecular "nano-tap" would behave very differently from those from a household tap 1 million times larger—researchers at the University of Warwick have found. This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3-D printers capable of nanoscale resolution.

Using a familiar tool in a way it was never intended to be used opens up a whole new method to explore materials, report UConn researchers in Proceedings of the National Academy of Science. Their specific findings could someday create much more energy-efficient computer chips, but the new technique itself could open up new discoveries in a broad range of stuffs.

Self-assembling nanomaterial offers pathway to more efficient, affordable harnessing of solar power

25.01. 2019 Nanotechnology News - Nanoscience, Nanotechnolgy, Nanotech News

Solar rays are a plentiful, clean source of energy that is becoming increasingly important as the world works to shift away from power sources that contribute to global warming. But current methods of harvesting solar charges are expensive and inefficient—with a theoretical efficiency limit of 33 percent. New nanomaterials developed by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center of The City University of New York (CUNY) could provide a pathway to more efficient and potentially affordable harvesting of solar energy.
