Physical Review Letters
Bottom-up approach provides first characterization of pyroelectric nanomaterials
By taking a "bottom-up" approach, researchers at the University of Illinois at Urbana-Champaign have observed for the first time that "size does matter," in regards "pyroelectricity," -- the current/voltage developed in response to temperature fluctuations that enables technologies such as infrared sensors, night-vision, and energy conversion units, to name a few.

'Tricorder' invention could put medical diagnosis and terrorism prevention in the palm of the hand
The hand-held scanners, or tricorders, of the Star Trek movies and television series are one step closer to reality now that a University of Missouri engineering team has invented a compact source of X-rays and other forms of radiation. The radiation source, which is the size of a stick of gum, could be used to create inexpensive and portable X-ray scanners for use by doctors, as well as to fight terrorism and aid exploration on this planet and others.

How the kilogram has put on weight
Using a state-of-the-art Theta-probe XPS machine experts at Newcastle University, UK, have shown the original kilogram is likely to be tens of micrograms heavier than it was when the first standard was set in 1875. And they say a suntan could be the key to helping it lose weight.

Turning smartphones into secure and versatile keys
It's already possible to open doors using an app -- but we are a long way from seeing widespread acceptance of this in the market. Now, researchers have developed a piece of software that will make the technology even more secure and versatile.

Rethinking bacterial persistence
EPFL scientists used microfluidics to observe the behavior of individual tuberculosis-like bacteria in the presence of antibiotics. Their observations call into question the prevailing theory of bacterial resistance, and they have proposed a new explanation for why some bacteria become resistant. The research is published January 4, 2013 in the journal Science.

Liquid crystal research, future applications advance
Contributing geometric and topological analyses of micro-materials, University of Massachusetts Amherst mathematician Robert Kusner aided experimental physicists at the University of Colorado by successfully explaining the observed "beautiful and complex patterns revealed" in three-dimensional liquid crystal experiments. The work is expected to lead to creation of new materials that can be actively controlled.

Aldrich Materials Science discovers liquid-free preparation of metal organic frameworks
Researchers from Aldrich Materials Science have discovered an innovative approach to fully excluding liquids from the preparation of MOFs. The liquid-free method means fewer potential contaminants, making the resulting MOFs ideal for applications requiring high purity, such as sensors and detectors or electronic and magnetic materials.

The paths of photons are random -- but coordinated
Researchers at the Niels Bohr Institute have demonstrated that photons (light particles) emitted from light sources embedded in a complex and disordered structure are able to mutually coordinate their paths through the medium. This is a consequence of the photons' wave properties, which give rise to the interaction between different possible routes.

Penn metamaterials experts show a way to reduce electrons' effective mass to nearly 0
The field of metamaterials involves augmenting materials with specially designed patterns, enabling those materials to manipulate electromagnetic waves and fields in previously impossible ways. Now, researchers from the University of Pennsylvania have come up with a theory for moving this phenomenon onto the quantum scale, laying out blueprints for materials where electrons have nearly zero effective mass. Such materials could make for faster circuits with novel properties.
