A team of UIC researchers in medicine, engineering and pharmacy will study whether a therapy now used to treat drug overdoses may protect against chemical attack. The researchers are investigating a high-fat liquid, called a lipid emulsion, already approved as a nutritional supplement and used off-label to treat overdoses of anesthetics, beta blockers, calcium-channel blockers and certain antidepressants.

Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices. Based on NIST's measurements, the new materials—a family of multilayered crystalline sandwiches—might enable a whole new class of compact, high-performance, high-efficiency components for devices such as cellular phones.

New research from North Carolina State University and the University of Minnesota finds that people in the United States want labels on food products that use nanotechnology – whether the nanotechnology is in the food or is used in food packaging. The research also shows that many people are willing to pay more for the labeling.

A team headed by scientists from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg have demonstrated that it also meets an important condition for use in novel lasers for terahertz pulses with long wavelengths. The direct emission of terahertz radiation would be useful in science, but no laser has yet been developed which can provide it. Theoretical studies have previously suggested that it could be possible with graphene. However, there were well-founded doubts - which the team in Hamburg has now dispelled. At the same time, the scientists discovered that the scope of application for graphene has its limitations though: in further measurements, they showed that the material cannot be used for efficient light harvesting in solar cells.

When it comes to designing extremely water-repellent surfaces, shape and size matter. That's the finding of a group of scientists at the U.S. Department of Energy's Brookhaven National Laboratory, who investigated the effects of differently shaped, nanoscale textures on a material's ability to force water droplets to roll off without wetting its surface. These findings and the methods used to fabricate such materials—published online October 21, 2013, in Advanced Materials—are highly relevant for a broad range of applications where water-resistance is important, including power generation and transportation.
