An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath. The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic metre, making it the lightest sound insulation ever manufactured.
Researchers at the University of Houston, in collaboration with Rice University, published a paper detailing how to improve energy density in a novel electric vehicle battery - a step toward a more cost-effective, easily recycled battery that would allow EVs to travel farther and charge faster at a low cost.
An innovative underwater robot known as Mesobot is providing researchers with deeper insight into the vast mid-ocean region known as the "twilight zone." Capable of tracking and recording high-resolution images of slow-moving and fragile zooplankton, gelatinous animals, and particles, Mesobot greatly expands scientists' ability to observe creatures in their mesopelagic habitat with minimal disturbance.
Optical cloaking allows objects to be hidden in plain sight by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them. In Journal of Applied Physics, researchers examined recent progress of developing invisibility cloaks that function in natural incoherent light and can be realized using standard optical components.
Researchers at the University of Colorado Boulder are addressing one aspect of creating fuel cells that can convert hydrogen and oxygen safely into water by developing new computational tools and models needed to better understand and manage the conversion process.
An international team of collaborators has made the first direct observation of the anionic redox reaction in a lithium-rich battery material. The research opens up pathways for improving existing battery cathodes--and designing new ones.
A new robot -- named WomBot -- that can be used to explore and study wombat burrows is presented in a study published in the journal SN Applied Sciences.
Jet packs, robot maids and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power sources.
UPTON, NY--A team of researchers led by chemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has studied an elusive property in cathode materials, called a valence gradient, to understand its effect on battery performance. The findings, published in Nature Communications, demonstrated that the valence gradient can serve as a new approach for stabilizing the structure of high-nickel-content cathodes against degradation and safety issues.
According to a new University of California San Diego article published in Nature Energy there are encouraging signs in emerging clean energy technology "niches"--countries, states or corporations--that are pioneering decarbonization.
