Gelatin is used in the pharmaceutical industry to encapsulate active agents. It protects against oxidation and overly quick release. Nanopores in the material have a significant influence on this, yet they are difficult to investigate. In experiments on gummy bears, researchers have now transferred a methodology to determine the free volume of gelatin preparations.

Magnetic vortices in thin films can encode information in the perpendicular magnetization pointing up or down relative to the vortex core. These binary states could be useful for non-volatile data storage devices such as RAM memories, but the switching between them must be fast and energy-efficient.

A longstanding question has been whether or not similar phenomenon can happen in more than one dimension. Researchers have uncovered new evidence showing that this can happen in quasi two-dimensional magnetic materials.

New research suggests that an ultra-thin layer of a metal and a semiconductor could be applied to essentially any rough or flexible material to produce a vividly colored coating. The technique, which exploits optical interference effects, could potentially be used on wearable fabrics or stretchable electronics.
