An experiment has revealed an unlikely behavior in a class of materials called frustrated magnets, addressing a long-debated question about the nature of these discontented quantum materials. The work represents a surprising discovery that down the road may suggest new research directions for advanced electronics. The study also someday may help clarify the mechanism of high-temperature superconductivity, the frictionless transmission of electricity.

Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer, and within minutes you have reproduced a replica accurate to within microns of the original object. This feat may soon be possible because of a new, tiny high-resolution 3-D imager developed at Caltech.

Delving into the world of the extremely small, researchers are exploring how biodegradable nanoparticles can precisely deliver anticancer drugs to attack neuroblastoma, an often-deadly children's cancer. The approach may represent a new fourth arm of targeted pediatric cancer treatment, joining T-cell immunotherapy, radioactive isotopes and kinase inhibitors that disrupt cancer-driving signaling.

Researchers have developed a scalable production method for a state of the art alloy for the use in solid state thermoelectric devices. This new alloy is nearly twice as efficient as existing materials and may lead to a new host of applications. Uses include refrigeration, consumer electronics, transportation as well as novel devices which have not been produced yet do to the inefficiencies of existing materials.

Novel enzymatically active membranes can complete two steps in one: they can enzymatically split proteins and simultaneously separate the products. The membranes are produced by cross-linking pepsin on a porous support, a simple process that is also applicable to other enzymes and on an industrial scale.

Researchers noticed a new kind of transport phenomenon for charges. In the phenomenon, a pair formed by a negative electron and a positive charge moves onto an interface, after which its 'message' is passed on to the other side of the interface, where it is carried on by a similar pair. The new theoretical result opens up interesting prospects for carrying out logical operations in electronics.

The development of graphene is closely related to the unique electronic structure, that is, Dirac cones. The cone which represents linear energy dispersion at Fermi level gives graphene massless fermions, leading to various quantum Hall effects, ultra high carrier mobility, and many other novel phenomena and properties.

A pair of light waves - one zipping clockwise the other counterclockwise around a microscopic track - may hold the key to creating the world's smallest gyroscope: one a fraction of the width of a human hair. By bringing this essential technology down to an entirely new scale, a team of applied physicists hopes to enable a new generation of phenomenally compact gyroscope-based navigation systems, among other intriguing applications.
