Ironing out the origins of wrinkles, creases and folds

Engineers from Brown University have mapped out the amounts of compression required to cause wrinkles, creases, and folds to form in rubbery materials. The findings could help engineers control the formation of these structures, which can be useful in designing nanostructured materials for flexible electronic devices or surfaces that require variable adhesion.

Injectable 'smart sponge' holds promise for controlled drug delivery

Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells.

Nature's nanostructures could inspire new hue-changing materials

Butterfly wings can do remarkable things with light, and humans are still trying to learn from them. Physicists have now uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species.

Surfing on acoustic waves

Researchers are able to make objects such as particles and liquid droplets fly in mid-air by letting them ride on acoustic waves. For the first time, they have been able to also control the movement of objects, merge droplets, letting them react chemically or biologically and even rotate a toothpick in the air.

Empowering innovation in photonics through collaboration

There is strength in numbers. That is the logic behind an EU-funded project that, by pooling the resources, know-how and technology of multiple organisations across Europe, has helped greatly to advance current research trends in the increasingly important field of photonics.
