Chemical treatment improves quantum dot lasers

ScienceDaily.com: Nanotechnology News - 16 октября, 2017 - 20:26
One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots. In new research the ~nanometer-sized dots are being doctored, or 'doped,' with additional electrons, a treatment that nudges the dots ever closer to producing the desired laser light with less stimulation and energy loss.

Nanotechnology innovation safety aspects - the case of graphene

Nanowerk.com - 16 октября, 2017 - 15:40
Currently, most graphene-based innovations are not yet at the level of large-scale commercial production. But public and private investments into graphene and its applications in products are large and whichever production methods eventually turn out to be successful, exposure to humans or the environment somewhere along the value chain or life-cycle of the material or product should be anticipated timely. A new review paper offers suggestions on how potential nanospecific safety issues can be addressed, by who and at what stage of the innovation process.
