Magnetic resonance imaging (MRI) can provide an effective way of supporting the development of the next generation of high-performance rechargeable batteries, according to research led by the University of Birmingham.
The technique, which was developed to detect the movement and deposition of sodium metal ions within a sodium battery, will enable faster evaluation of new battery materials, and help to accelerate this type of battery's route to market.
Madison, WI, April 28, 2020 - For the first time, a new publication by the USDA Forest Service delivers an overview of the status and trends of greenhouse gas emissions and removals from forest land, woodlands, hardwood products, and urban trees nationally for 49 U.S. states.
Tuning in to the signature 'whistles' of dolphins could prove a game-changer in being able to accurately track the movements of this much-loved protected species.
Researchers from Edith Cowan University (ECU) and Curtin University in Australia have moved an important step closer to using sound rather than sight to track individual dolphin activity.
Researchers from Higher School of Theoretical Mechanics of Peter the Great St.Petersburg Polytechnic University (SPbPU) and Tel Aviv University proposed a new approach to improve the efficiency of mathematical modeling of the processes in materials at the nanoscale. It is essential for the further development of nanotechnology.
Researchers in China have engineered a microbe that shows promise as the foundation of an efficient way to break down polyethylene terephthalate (PET), a common plastic fiber used to manufacture clothing and disposable consumer products.
The researchers published their findings in Microbial Biotechnology on April 28, 2020.
The microscale reentrant-honeycomb shaped, graphene-based electrode is characterized by an accordion-like structural stretchability. A stretchable gel electrolyte and stretchable separator are also developed for all-component stretchable full cells, applying for future stretchable devices.
When a dead body is found, one of the first things a forensic pathologist tries to do is estimate the time of death. There are several ways to do this, including measuring body temperature or observing insect activity, but these methods don't always work for corpses found in water. Now, researchers are reporting a mouse study in ACS' Journal of Proteome Research showing that certain proteins in bones could be used for this determination.
Our immune system not only protects us against infection, but also against cancer. This powerful protection is based in particular on the activation of special cells of the immune system, CD8+ T cells. These cells recognize infected or cancer cells and kill them specifically.
"The ability of the immune system and especially CD8+ T cells to eliminate cancer cells in tissues such as the lung, gut and liver is often limited in tumor patients," explains Percy Knolle, Professor of Molecular Immunology at the Technical University of Munich (TUM).
Yale University researchers and colleagues in Hong Kong and China have developed an approach for rapidly tracking population flows that could help policymakers worldwide more effectively assess risk of disease spread and allocate limited resources as they combat the COVID-19 pandemic.
Vietnam features extensive ethnolinguistic diversity and occupies a key position in Mainland Southeast Asia (MSEA). Vietnam, with its borders to China, Laos and Cambodia, has a rich geographical diversity, and ample access to human migration with the Red River and Mekong deltas, and a long coastline.
A simple pretreatment step enables membranes to be enhanced using atomic layer deposition, a technique that can improve performance and introduce new surface properties.
Lithium-sulfur batteries have been hailed as the next big step in battery technology, promising significantly longer use for everything from cellphones to electric vehicles on a single charge, while being more environmentally sustainable to produce than current lithium-ion batteries. However, these batteries don't last as long as their lithium-ion counterparts, degrading over time.
ADELPHI, Md. -- In recent years, lithium-ion batteries have become better at supplying energy to Soldiers in the field, but the current generation of batteries never reaches its highest energy potential. Army researchers are extremely focused on solving this challenge and providing the power Soldiers demand.
At the U.S. Army Combat Capabilities Development Command's Army Research Laboratory, in collaboration with the University of Maryland, scientists may have found a solution.
Researchers from the University of York have recreated how toxins from smoking cause unique patterns of DNA damage. The discovery could help scientists better understand the cause of bladder cancer and the link to smoking.
The causes of bladder cancer remain largely unknown, however smoking is seen as the main risk factor for the disease.
The global pandemic has put a focus on essential workers, those we rely on for basic services. Workers who pick crops, from strawberries to apples to nuts, already face harsh conditions harvesting in fields during summer harvest months. Those conditions will worsen significantly over the coming decades.
