A safe and effective way to whiten teeth

ScienceDaily.com: Nanotechnology News - 18 июля, 2018 - 17:47
In the age of Instagram and Snapchat, everyone wants to have perfect pearly whites. To get a brighter smile, consumers can opt for over the counter teeth-whitening treatments or a trip to the dentist to have their teeth bleached professionally. But both types of treatments can harm teeth. Researchers have now developed a new, less destructive method.

Splitting water: Nanoscale imaging yields key insights

ScienceDaily.com: Nanotechnology News - 18 июля, 2018 - 16:25
In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel -- just as plants do -- researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. Now scientists have pioneered a technique that uses nanoscale imaging to understand how local, nanoscale properties can affect a material's macroscopic performance.

Transmission of specific colors of light over long distances

ScienceDaily.com: Nanotechnology News - 17 июля, 2018 - 18:24
Researchers have reached a new milestone on the way to optical computing, or the use of light instead of electricity for computing. They explored a new way to select and send light of a specific color using long silicon wires that are several hundred nanometers in diameter and their work enabled a new type of nanoscale ''light switch'' that can turn on and off the transmission of one color of light over very long distances.
