Electrons in graphene corralled using new quantum tool

Researchers have succeeded in creating a new 'whispering gallery' effect for electrons in a sheet of graphene - making it possible to precisely control a region that reflects electrons within the material. They say the accomplishment could provide a basic building block for new kinds of electronic lenses, as well as quantum-based devices that combine electronics and optics.

Using light to probe acoustic tuning in gold nanodisks

In a study that could open doors for new applications of photonics from molecular sensing to wireless communications, scientists have discovered a new method to tune the light-induced vibrations of nanoparticles through slight alterations to the surface to which the particles are attached.

Putting a new spin on plasmonics

Researchers have discovered a novel way of combining plasmonic and magneto-optical effects. They experimentally demonstrated that patterning of magnetic materials into arrays of nanoscale dots can lead to a very strong and highly controllable modification of the polarization of light when the beam reflects from the array.

A 'super-cool' way to deliver drugs

Some substances, when they undergo a process called rapid-freezing or supercooling, remain in liquid form - even at below-freezing temperatures. A new study is the first to break down the rules governing the complex process of crystallization through rapid-cooling. Its findings may revolutionize the delivery of drugs in the human body, providing a way to 'freeze' the drugs at an optimal time and location in the body.
