Splitting water: Nanoscale imaging yields key insights

ScienceDaily.com: Nanotechnology News - Wed, 07/18/2018 - 17:25
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 - Tue, 07/17/2018 - 19:24
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.

Single-celled architects inspire new nanotechnology

ScienceDaily.com: Nanotechnology News - Mon, 07/16/2018 - 23:16
Scientists have designed a range of nanostructures resembling marine diatoms -- tiny unicellular creatures. To achieve this, they borrow techniques used by naturally-occurring diatoms to deposit layers of silica -- the primary constituent in glass -- in order to grow their intricate shells. Using a technique known as DNA origami, the group designed nanoscale platforms of various shapes to which particles of silica, drawn by electrical charge, could stick.
