Gem-like nanoparticles of precious metals shine as catalysts

A Northwestern University research team has developed a new method for making highly desirable catalysts from metal nanoparticles that could lead to better fuel cells, among other applications. The researchers also discovered ...

Is Bitcoin the new gold standard or another fiat?

A statistical analysis of volatility in cryptocurrencies has been carried out using a news impact curve. The analysis provides empirical evidence that could help economists decide whether these modern digital currencies are ...

High reaction rates even without precious metals

Non-precious metal nanoparticles could one day replace expensive catalysts for hydrogen production. However, it is often difficult to determine what reaction rates they can achieve, especially when it comes to oxide particles. ...

A superior, low-cost catalyst for water-splitting

In a significant step toward large-scale hydrogen production, researchers at the Indian Institute of Science (IISc) have developed a low-cost catalyst that can speed up the splitting of water to produce hydrogen gas.

Life cycle of sulphur predicts location of valuable minerals

A team of researchers from The University of Western Australia and two Canadian universities has applied a first-of-its-kind technique that measures the long-term life cycle of sulphur, helping to explain the preferential ...

A protective shield for sensitive enzymes in biofuel cells

An international team of researchers has developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable ...
