High-valence metal-doped amorphous IrOx as stable electrocatalyst for acidic oxygen evolution reaction
Hydrogen has been regarded as a potential energy carrier instead of fossil fuels, addressing energy demand and environmental issues. Proton exchange membrane water electrolysis (PEMWE), with its high energy density, elevated hydrogen purity, and rapi.....»»
Study finds female academics less likely to win prizes, even when the award is named after a woman
A new study shows that female academics are significantly underrepresented in winning academic prizes and having awards named after them......»»
400-year-old mystery of why early explosive produces purple smoke solved by academics
Scientists at the University of Bristol have discovered why fulminating gold—the world's first known high explosive—produces a purple smoke when it detonates, solving a 400-year-old alchemy puzzle......»»
Researchers observe the operating principle of "promoters" in a catalytic reaction in real-time
For the first time, researchers at TU Wien have successfully observed the operating principle of so-called "promoters" in a catalytic reaction in real-time. These promoters play an important role in technology, but so far there is only limited unders.....»»
To study radioactive neptunium and plutonium, researchers establish a novel chemistry
Oxidation is the process where atoms lose electrons during a chemical reaction. Among the radioactive elements, neptunium and plutonium are much harder to oxidize than uranium......»»

Researchers improve water splitting reaction for green hydrogen gas production
Green hydrogen (or H2) produced from renewable energy resources is the fuel of a decarbonized future. Electrolysis, or splitting of water into oxygen and hydrogen with the help of an electrochemical cell, is one of the most popular ways of producing.....»»
A supernova devastated our ozone in 2022, new study reveals
In October of 2022, telescopes picked up a jet of high energy from a supernova that exploded 1.9 billion light-years away from Earth. This gamma-ray … The post A supernova devastated our ozone in 2022, new study reveals appeared first on BGR......»»
Did this chemical reaction create the building blocks of life on Earth?
How did life begin? How did chemical reactions on the early Earth create complex, self-replicating structures that developed into living things as we know them?.....»»
Researchers construct modularized catalytic system for transfer hydrogenation
The precise catalytic conversion of chemical bonds is a paramount goal in catalysis. Enzymes, as efficient biocatalysts, are well known for their high catalytic activity, selectivity, and substrate specificity under mild reaction conditions, which ca.....»»
ALMA observations shed more light on molecular clouds associated with supernova remnant LHA 120-N49
Using the Atacama Large Millimeter/Submillimeter Array (ALMA), an international team of astronomers has observed a supernova remnant known as LHA 120-N49. Results of the observational campaign, published November 3 on the pre-print server arXiv, prov.....»»

Mario Kart 8 update nerfs controversial “sandbagging” strategy
Nine years after launch, racers can't intentionally hang back for the best items anymore. Baby Luigi represents the reaction of sandbagging racers in this artistic rendering. (credit: Nintendo) Since Mario Kart 8's launc.....»»
Astronomers are hoping to detect gravitational waves coming from supernova 1987A
A supernova explosion is a cataclysmic explosion that marks the violent end of a massive star's life. During the event, the star releases immense amounts of energy, often outshining the combined light from all the stars in the host galaxy for a very.....»»
Workplace protections needed for menstruation and menopause, says paper
As the Australian government announces a Senate inquiry into the impact of menopause on women's health, careers and finances, academics from the Body@Work Project have published a paper in the University of Oxford Human Rights Hub Journal examining i.....»»
