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.
An experimental drug in early development for aggressive brain tumors can cross the blood-brain tumor barrier and kill tumor cells and block the growth of tumor blood vessels, according to a new study.
New research describes the synthesis of nanodiamonds by the detonation of nanostructured explosive charges thus obtaining nanodiamond particles of a size comprised between 1 and 3 nm.Never before a nanostructured charge has been detonated to produce diamond nanoparticles.
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.
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.
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.
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.
Researchers in Singapore have designed an electronic switch that responds to changes in a magnetic field1. The device relies on graphene, a strong and flexible electricity-conducting layer of carbon atoms arranged in a honeycomb pattern.
