Organic photovoltaic material offers great promise for solar energy. The semiconducting plastic is lightweight, flexible, relatively inexpensive and easy to make. The problem is that, unlike inorganic photovoltaic material, it is not very efficient or stable. But work by Adam Willard, an assistant professor in the Dept. of Chemistry at MIT, has the potential to change that.
The whorls and ridges unique to your fingerprint may reveal more than just identity. Research from North Carolina State Univ. indicates these unique stamps may give clues to your ancestral background.
Fusion reactors could become an economically viable means of generating electricity within a few decades, and policy makers should start planning to build them as a replacement for conventional nuclear power stations, according to new research.
When working with valuable cell cultures, contaminating microorganisms, especially mycoplasma species, can be detrimental to the accuracy of resulting data, while introducing a potential hazard to laboratory personnel. Fortunately, the biological safety cabinet (BSC) provides a ventilated sterile work environment in which to safely handle biological samples, protecting both the cultures and users from hazardous particles.
Months of warning signs from Mauna Loa, on Hawaii’s Big Island, prompted the U.S. Geological Survey to recently start releasing weekly updates on activity at the world’s largest active volcano. For now, such warning signs can only rely on external clues, like earthquakes and gas emissions. But a Univ. of Washington simulation has managed to demonstrate what’s happening deep inside the volcano.
Earlier this year, researchers David M. Martill, Helmut Tischlinger and Nicholas R. Longrich published a paper on a four-legged snake fossil dating from the early Cretaceous period. Found in Brazil’s Crato Formation, Tetrapodophis’ skeleton displayed the sinuous body found in modern day snakes, but small hinged limbs jutted from its sides.
Recent reports of chemical weapons attacks in the Middle East underscore the urgent need for new ways to guard against their toxic effects. Toward that end, scientists report in ACS Applied Materials & Interfaces a new hydrogel coating that neutralizes both mustard gas and nerve agent VX. It could someday be applied to materials such as clothing and paint.
Researchers for the first time have applied a modern theory of heat transport in experiments with semiconductors used in computers and lasers, with implications for the design of devices that convert waste heat into electricity and the control of overheating in miniaturized and high–speed electronic components.
Scientists of research institute MESA+ of Twente Univ. have developed a technology for contactless deposition of liquids at nanoscale. In doing so, they make use of an electric field. Their technology will lead to new 3-D applications and can be of great value to, for example, cell research, nanolithography and printable electronics.
Watching the clouds go by, swirls of white puff up and melt away. The changes mirror mixing within the clouds as drier air mingles with water-saturated air. New research led by Michigan Technological Univ. with support from the National Center for Atmospheric Research (NCAR) and the Max Planck Institute for Chemistry, Mainz Univ., analyzes this mixing with holographic imaging and an airborne laboratory.
Before embarking on a transcontinental journey, jet airplanes fill up with tens of thousands of gallons of fuel. In the event of a crash, such large quantities of fuel increase the severity of an explosion upon impact. Researchers at Caltech and JPL have discovered a polymeric fuel additive that can reduce the intensity of post-impact explosions that occur during accidents and terrorist acts.
Researchers at Chalmers Univ. of Technology have arrived at how what is known as time-reversal symmetry can break in one class of superconducting material. The results have been published in Nature Physics.
Asynt has developed DrySyn NMR Heating Blocks to enable safe, effective and uniform heating of up to 10 NMR tubes on a conventional hotplate stirrer. This new DrySyn unit allows users to use standard NMR tubes as a reaction vessel for applications including catalyst screening experiments and reaction monitoring as well as studying broad peaks, temperature dependent solubility issues and conformational changes.
Like the ancient Egyptians, Bronze Age Britons practiced their own form of mummification. And it may have been a wide-spread funerary practice, according to new research from the Univ. of Sheffield, Univ. of Manchester and Univ. College London.
The Obama administration on Thursday established stricter limits on the smog-causing pollution linked to asthma and respiratory illness, drawing swift condemnation from business leaders and Republicans who warned of damage to the economy.
