A new semiconductor laser developed at Yale has the potential to significantly improve the imaging quality of the next generation of high-tech microscopes, laser projectors, photolithography, holography, and biomedical imaging.
The Phantoms Foundation and ICEX Spain Trade and Investment, in cooperation with the Embassy of Spain (Economic and Commercial Office) in Tokyo bring together, for the eighth time, a nanoscience and nanotechnology Pavilion at nano tech 2015 (Spanish Pavilion - East Hall 6/Booth 6P-23).
Artificial implants such as pacemakers often cause complications because the body identifies them as foreign objects. Researchers have now demonstrated a simple method to fabricate cellulose-sheaths for implants, whose micro-structured surface makes them especially biocompatible.
A new composite material which prevents metal corrosion in an environmentally friendly way, even under extreme conditions is presented. It can be used wherever metals are exposed to severe weather conditions, aggressive gases, media containing salt, heavy wear or high pressures.
Researchers have successfully demonstrated how to both enhance light emission and capture light from metamaterials embedded with light emitting nanocrystals. The breakthrough could lead to a range of applications including ultrafast LEDs, nanoscale lasers and efficient single photon sources.
One way of removing harmful nitrate from drinking water is to catalyse its conversion to nitrogen. This process suffers from the drawback that it often produces ammonia. By using palladium nanoparticles as a catalyst, and by carefully controlling their size, this drawback can be partially eliminated.
