Scientists are reporting development of a squishy gel that, when compressed at a key location such as a painful knee joint, releases anti-inflammatory medicine. The new material could someday deliver medications when and where osteoarthritis patients need it most.
Researchers from the NIST Center for Nanoscale Science and Technology (CNST) have demonstrated a new low-energy electron beam technique and used it to probe the nanoscale electronic properties of grain boundaries and grain interiors in cadmium telluride (CdTe) solar cells. Their results suggest that controlling material properties near the grain boundaries could provide a path for increasing the efficiency of such solar cells.
Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and an important aspect of personalized medicine is to tailor therapies to individuals to reduce the chances of adverse events. Now researchers from North Carolina State Univ. have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.
An international multidisciplinary team including researchers at the Univ. of Illinois at Urbana/Champaign and the National Institute of Biomedical Imaging and Bioengineering has developed a sophisticated ”electronic skin” that adheres non-invasively to human skin, conforms well to contours, and provides a detailed temperature map of any surface of the body.
From green electricity tariffs to car sharing schemes, many sustainable products and services are being brought to market by start-ups. However, there has been relatively little research into how and why individuals take this step and whether their start-ups become a success. Fourteen European institutes coordinated by the Technical Univ. of Munich will be investigating this trend to see what potential it holds for a sustainable economy.
A new technique developed at the Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power electric vehicles (EVs) and other applications. The technique, which uses soft x-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode.
In a finding of relevance to the search for life in our solar system, researchers at the Georgia Institute of Technology, Univ. of Texas at Austin’s Institute for Geophysics and the Max Planck Institute for Solar System Research have shown that the subsurface ocean on Jupiter’s moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life.
The first long-term U.S. field trials of Miscanthus x giganteus reveal that its exceptional yields, though reduced somewhat after five years of growth, are still more than twice those of switchgrass, a perennial grass used as a bioenergy feedstock. Miscanthus grown in Illinois also outperforms even the high yields found in earlier studies of the crop in Europe, the researchers found.
BP's strategy after the Deepwater Horizon tragedy: Go deeper. BP is leading an industry-wide push to develop technology that can retrieve oil from formations that are so deep under the sea floor, and under such high pressure and temperature, that conventional equipment would melt or be crushed by the conditions.
The solar panel installer SolarCity is beginning to address one of solar power's big drawbacks: The sun doesn't always shine. The solution: big battery packs that will provide backup power while lowering electric bills. The supplier: electric car maker Tesla Motors, whose CEO Elon Musk is also the chairman of SolarCity.
The outer shell of a droplet of oil on a surface has a thin skin which allows it to hold its shape like a small dome. Researchers at the Univ. of Missouri have developed a technique to form a virtual wall for oily liquids that will help confine them to a certain area, aiding researchers who are studying these complex molecules. The finding could also help halt industrial oil spills.
At high pressures and low temperatures, such as those in the deep oceans, carbon dioxide occurs as a liquid that is denser than seawater. Researchers in England have identified regions beneath the oceans where the igneous rocks of the upper ocean crust could safely store very large volumes of carbon dioxide.
While 3-D pens and printers are enjoyed by students, artists and makers, innovative American companies are using similar equipment to manufacture aerospace, automotive and medical technologies. Many of the foundational techniques for additive manufacturing, such as selective laser sintering, sheet lamination and 3-D printing, have their roots in discoveries and patents from the 1980s.
A multinational team led by Chinese researchers in collaboration with U.S. and European partners has successfully demonstrated a novel technique for suppressing instabilities that can cut short the life of controlled fusion reactions. The team combined the new technique with a method that Princeton Plasma Physics Laboratory has developed for protecting the walls that surround the hot, charged plasma gas that fuels fusion reactions.
Scientists at Penn State Univ. have developed a method that enables a more accurate prediction of how ribonucleic acid molecules (RNAs) fold within living cells, shedding new light on how plants, as well as other living organisms, respond to environmental conditions. The advance was made possible by the ability to analyze more than 10,000 RNA molecules in a single cell.
