A close up on the real world: Atomic migration under ambient conditions

ScienceDaily.com: Nanotechnology News - Tue, 10/08/2019 - 17:43
Researchers have reported an environmental transmission electron microscopy technique that has allowed in situ visualization of the atomic changes of a metal surface in an electric field under ambient conditions. The activation of oxygen gas molecules by electron tunneling was found to result in atomic migration that could be followed progressively. It is hoped that the tunneling-electron-attached-gas process will provide valuable insight for the development of nanoparticle catalyst and quantum material applications.

Hydrogel paint - hydrogel coatings off the shelf

NanoWerk.com - Tue, 10/08/2019 - 11:03
As a coating, hydrogels bring many advantages to regular solid surfaces, uniting the superior properties of the substrate with the superior properties of the hydrogel. However, making hydrogel coatings outside a laboratory environment can be difficult. Inspired by the economics of paint manufacturing, we have developed a technique for hydrogel coating preparation that breaks the process up into several steps. This step-wise synthetic pattern, decoupling polymerization from crosslinking and interlinking, divides the labor between the hydrogel coating maker and its user.
