Dramatically longer-lasting, faster-charging and safer lithium metal batteries may be possible, according to Penn State research, recently published in Nature Energy. The researchers developed a 3D cross-linked polymer sponge that attaches to the metal plating of a battery anode.

“This project aims to develop the next generation of metal batteries,” said Donghai Wang, professor of mechanical engineering and the principal investigator of the project. “Lithium metal has been tried in batteries for decades, but there are some fundamental issues that inhibit their advancement.”

Under additional strain, like in the fa...

Omega-3 fatty acids Reduce the risk of Premature Birth

A new Cochrane Review published today has found that increasing the intake of omega-3 long-chain polyunsaturated fatty acids (LCPUFA) during pregnancy reduces the risk of premature births. Premature birth is the leading cause of death for children under 5 years old worldwide, accounting for close to one million deaths annually. Premature babies are at higher risk of a range of long-term conditions including visual impairment, developmental delay and learning difficulties.

“We know premature birth is a critical global he...

Metallic Nanoparticles light up another path towards Eco-friendly Catalysts

Each dendrimer molecule hosts a subnano-sized metallic particle that allows for the oxidation of aromatic hydrocarbons, such as toluene (left), to produce useful organic compounds, such as benzoic acid (right). Oxygen molecules are represented in red.

Platinum clusters consisting 19 atoms perform 50 times higher catalytic activity. Scientists at Tokyo Institute of Technology produced subnano-sized metallic particles that are very effective as catalysts for the oxidation of hydrocarbons. These catalysts can be as much as 50 times more effective than well-known Au-Pd bimetallic nanocatalysts.

The oxidation of aromatic hydrocarbons is critically important for producing a great variety of useful organic compounds that are used throughout all types of industries...

Astronomers find possible Elusive Star behind Supernova

This is an artist's concept of a blue supergiant star that once existed inside a cluster of young stars in the spiral galaxy NGC 3938, located 65 million light-years away. It exploded as a supernova in 2017, and Hubble Space Telescope archival photos were used to locate the doomed progenitor star, as it looked in 2007. The star may have been as massive as 50 suns and burned at a furious rate, making it hotter and bluer than our Sun. It was so hot, it had lost its outer layers of hydrogen and helium. When it exploded in 2017, astronomers categorized it as a Type Ic supernova because of the lack of hydrogen and helium in the supernova's spectrum. In an alternative scenario (not shown here) a binary companion to the massive star may have stripped off its hydrogen and helium layers. Credits: NASA, ESA, and J. Olmsted (STScI)
