A new technique for monitoring carbon dioxide could help the energy industry’s efforts to reduce future greenhouse gas emissions, scientists have found. In a new paper published in the International Journal of Greenhouse Gas Control, researchers describe how they have used the unique signature from traces of the noble gases (helium, neon and argon) to monitor the fate of carbon dioxide stored underground.
Biomedical engineers have demonstrated a proof-of-principle technique that could give women and their oncologists more personalized information to help them choose options for treating breast cancer. Thanks to diagnostic tests, clinicians and patients can already know the type of breast cancer they're up against, but one big question remains: How likely is it that the cancer will invade other parts of the body?
Using a newly developed fabrication method, a research team has attained better than a 15% energy conversion efficiency from perovskite solar cells larger than one square centimeter area. The researchers, from Brown Univ. and the National Renewable Energy Lab, have reported their findings in Advanced Materials.
New research by chemists at Brookhaven National Laboratory offers clues that could help scientists design more effective catalysts for transforming carbon dioxide to useful products. The study reveals how a simple rearrangement of molecular attachments on an iridium hydride catalyst can greatly improve its ability to coax notoriously stable carbon dioxide molecules to react.
Over the summer, Betty Hong, assistant professor of neuroscience, spent a week at the Janelia Research Campus in Ashburn, Va., interacting and brainstorming with other researchers from around the country interested in olfaction, our sense of smell.
Teams at HZB have already acquired extensive experience with silicon-perovskite tandem cells. A particularly effective complement to conventional silicon is the hybrid material called perovskite. It has a band gap of 1.6 electron volts with organic, as well as inorganic, components. However, it is very difficult to provide the perovskite layer with a transparent front contact.
Theoretically, nanocellulose could be the next hot supermaterial. A class of biological materials found within numerous natural systems, most notably trees, cellulose nanocrystals have captured researchers’ attention for their extreme strength, toughness, light weight and elasticity.
Researchers at the Univ. of Illinois at Urbana-Champaign have introduced a new class of light-emitting quantum dots with tunable and equalized fluorescence brightness across a broad range of colors. This results in more accurate measurements of molecules in diseased tissue and improved quantitative imaging capabilities.
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.
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.
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.
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.
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.
