Public Release: 23-Jul-2013
 Scientific ReportsDirect nitrogen fixation for low cost energy conversion A simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets, which could be used in dye-sensitized solar cells and fuel cells, is published in Scientific Reports today. The work, carried out at Ulsan National Institute of Science and Technology in South Korea, could be a step towards replacing conventional platinum (Pt)-based catalysts for energy conversion.

Proceedings of the National Academy of SciencesOff-grid sterilization with Rice U.'s 'solar steam' Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The "solar steam" sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat. The technology is described online in the Proceedings of the National Academy of Sciences Early Edition.

Proceedings of the National Academy of SciencesChips that mimic the brain Novel microchips imitate the brain's information processing in real time. Neuroinformatics researchers from the University of Zurich and ETH Zurich together with colleagues from the EU and US demonstrate how complex cognitive abilities can be incorporated into electronic systems made with so-called neuromorphic chips: They show how to assemble and configure these electronic systems to function in a way similar to an actual brain.

American Crystallographic Association Annual MeetingUnusual material expands dramatically under pressure If you squeeze a normal object in all directions, it shrinks in all directions. But a few strange materials will actually grow in one dimension when compressed. A team of chemists has now discovered a structure that takes this property to a new level, expanding more dramatically under pressure than any other known material. Contact: Catherine Meyers

Soft MatterMilikelvins drive droplet evaporation Evaporation is so common that everybody thinks it's a well understood phenomenon. Appearances can be, however, deceptive. Recently, a new, earlier not predicted mechanism of evaporation was discovered. Experiments and simulations performed at the Institute of Physical Chemistry of the Polish Academy of Sciences and the Institute of Physics of the PAS not only confirm its existence, but also indicate that it plays the crucial role in evaporation process in the nanoscale.

SciencePenn researchers help show new way to study and improve catalytic reactions A study by researchers at the University of Pennsylvania, the University of Trieste and Brookhaven National Laboratory has shown a way to precisely design the active elements of a certain class of catalysts, showing which parameters are most critical for improving performance. This highly controlled process could be a new paradigm for fine-tuning catalysts used in everything from making new materials to environmental remediation.

CellAnother beautiful helix for biology, this time reminiscent of a parking garage The endoplasmic reticulum is the protein-making factory within cells consisting of tightly stacked sheets of membrane studded with the molecules that make proteins. Now, researchers have refined a new microscopy imaging method to visualize exactly how the ER sheets are stacked, revealing that the 3D structure of the sheets resembles a parking garage. This structure allows for the dense packing of ER sheets, maximizing the amount of space available for protein synthesis. Contact: Mary Beth O'Leary

Proceedings of the Royal Society AIroning out the origins of wrinkles, creases and folds 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.

Molecular TherapyNano drug crosses blood-brain tumor barrier, targets brain-tumor cells and blood vessels The blood-brain barrier protects the brain from poisons but also prevents drugs from reaching brain tumors. A preclinical study shows that an experimental nanotechnology drug called SapC-DOPS crosses the tumor blood-brain barrier, targets brain-tumor cells and retards growth of tumor blood vessels. The findings also show why the agent targets tumor cells and recommend the drug's further development as a novel treatment for glioblastoma.

Optical Materials ExpressDeciphering butterflies' designer colors: Findings could inspire new hue-changing materials A team of researchers in Hong Kong has uncovered how subtle differences in the tiny crystals of butterfly wings create stunningly varied patterns of color even among closely related species. The discovery, reported today in the Optical Society's open-access journal Optical Materials Express, could lead to new coatings for manufactured materials that could change color by design, if researchers can figure out how to replicate the wings' light-manipulating properties.

Proceedings of the National Academy of SciencesResearchers step closer to custom-building new blood vessels Researchers at Johns Hopkins have coaxed stem cells into forming networks of new blood vessels in the laboratory, then successfully transplanted them into mice. The stem cells are made by reprogramming ordinary cells, so the new technique could potentially be used to make blood vessels genetically matched to individual patients and unlikely to be rejected by their immune systems, the investigators say.

Chemistry: a European JournalUsing pressure to swell pores, not crush them High pressure doesn't crush zeolites -- it actually makes interior nanopores expand. Researchers show how "super-hydration" inserts more water molecules into the cavities than can fit under ambient conditions. Contact: Steven Powell
