A University of Texas at Dallas researcher has made a discovery that could open the door to cellphone and car batteries that last five times longer than current ones.
Dr. Kyeongjae Cho, professor of materials science and engineering in the Erik Jonsson School of Engineering and Computer Science, has discovered new catalyst materials for lithium-air batteries that jumpstart efforts at expanding battery capacity. The research was published in Nature Energy.
RMIT researchers have shown how fired-clay bricks made with cigarette butts can save energy and help solve a global littering problem.
Trillions of cigarettes are produced every year worldwide, resulting in millions of tonnes of toxic waste being dumped into the environment in the form of cigarette butts.
As butts have poor biodegradability, it can take many years for them to break down, while heavy metals such as arsenic, chromium, nickel and cadmium trapped in the filters leach into soil and waterways.
Bathing a patient in LED light may someday offer a new way to locate tumors, according to Rice University researchers.
The spectral triangulation system developed by Rice chemist Bruce Weisman and his colleagues is intended to pinpoint targeted cancer tumors tagged with antibody-linked carbon nanotubes. It is described in a paper in the Royal Society of Chemistry journal Nanoscale.
In a South Korean port, two research ships are being equipped with instruments that will measure sunlight interacting with the ocean and capture the microscopic life that ebbs and flows with the currents. As part of the Korea-United States Ocean Color (KORUS-OC) expedition, scientists from the Korean Institute of Ocean Science and Technology (KIOST), NASA and other U.S. institutions are launching an 18-day field campaign to characterize the daily changes of the seas surrounding South Korea.
A biosensor developed by researchers at the National Nanotechnology Laboratory (LNNano) in Campinas, São Paulo State, Brazil, has been proven capable of detecting molecules associated with neurodegenerative diseases and some types of cancer.
OAK RIDGE, Tenn., May 19, 2016 - A method to produce significant amounts of semiconducting nanoparticles for light-emitting displays, sensors, solar panels and biomedical applications has gained momentum with a demonstration by researchers at the Department of Energy's Oak Ridge National Laboratory.
Transporting power sources in the coldest places may be easier with a new re-chargeable, non-metallic battery from Japan. This "eco battery" could provide portable sources of power in environments like refrigerated factories or extreme winter environments.
A team of researchers from University of Cincinnati (UC) in Cincinnati, OH have developed a novel microfluidic device, which combines the inertial effect of fluid and microscale vortices generated in microchambers, to achieve simultaneous double sorting of rare target cells and removal of background cells. Sorting and purification of target cells from complex cellular samples is a critical sample preparation step in cell biology research and clinical diagnostics.
Increased water use in the rapidly growing oil industry in North Dakota's Bakken oil shale region, or play, is surprisingly due not only to oil well development but also to people, according to a recent study by the U.S. Department of Energy's (DOE) Argonne National Laboratory.
Increased oil development in that region in recent years has attracted thousands of oilfield employees. From 2010 to 2012, nearly 24,000 temporary oilfield workers joined the approximately 27,000 permanent residents in Williams Country, the seat of the region's commercial oil industry.
WASHINGTON - The 2011 Fukushima Daiichi nuclear accident should serve as a wake-up call to nuclear plant operators and regulators on the critical importance of measuring, maintaining, and restoring cooling in spent fuel pools during severe accidents and terrorist attacks, says a new report from the National Academies of Sciences, Engineering, and Medicine. This report is the second and final phase of a congressionally mandated study on what lessons can be learned from the Fukushima Daiichi nuclear accident. The report from Phase 1 of this study was released in July 2014.
Some adhesives may soon have a metallic sheen and be particularly easy to unstick. Researchers at the Max Planck Institute for Intelligent Systems in Stuttgart are suggesting gallium as just such a reversible adhesive. By inducing slight changes in temperature, they can control whether a layer of gallium sticks or not. This is based on the fact that gallium transitions from a solid state to a liquid state at around 30 degrees Celsius.
Chemists at the Complutense University of Madrid have developed a method that allows brewers to measure the freshness of beer, using a polymer sensor that changes colour upon detecting furfural, a compound that appears when this beverage ages and gives it a stale flavour. The sensor can be controlled from a smartphone app also created by the team.
(Boston)-- Transplanting a preformed dense and coherent sheet of regenerative stem cells directly onto damaged heart, cartilage or bone tissue of ailing patients often is a more promising route to recovery than transplanting the cells just loosely mixed together. The challenge in obtaining intact cell sheets, however, lies in releasing them from the substrate they are grown on in the culture dish quickly and without affecting their efficiency.
New research from North Carolina State University finds that bees in urban areas stick to a flower-nectar diet, steering clear of processed sugars found in soda and other junk food.
Scientists have developed a new type of graphene-based transistor and using modelling they have demonstrated that it has ultralow power consumption compared with other similar transistor devices. The findings have been published in a paper in the journal Scientific Reports. The most important effect of reducing power consumption is that it enables the clock speed of processors to be increased. According to calculations, the increase could be as high as two orders of magnitude.
