On the line: Watching nanoparticles get in shape

Liquid structures—liquid droplets that maintain a specific shape—are useful for a variety of applications, from food processing to cosmetics, medicine, and even petroleum extraction, but researchers have yet to tap into ...

Imaging a molecular switch

Scanning probe microscopes like the scanning tunneling microscope and the atomic force microscope give researchers valuable information about individual molecules. One of the most interesting areas of research is molecular ...

Dewdrops on a spiderweb reveal the physics behind cell structures

As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon ...

How metal atoms can arrange themselves on an insulator

In order to produce tiny electronic memories or sensors in the future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now ...

Nanoparticle jamming at the water-oil interface

The online cover of Science Advances this week features the assembly of nanoparticle surfactants at a solid-liquid interface using advanced microscopy techniques such as laser scanning confocal microscopy and atomic force ...
