Previously unknown mechanism drives evaporation at the nanoscale

Evaporation is so common that everybody thinks it is a well understood phenomenon. Appearances can be, however, deceptive. Recently, a new, earlier not predicted mechanism of evaporation was discovered. Experiments and simulations not only confirm its existence, but also indicate that it plays the crucial role in evaporation process in the nanoscale.

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.
