• Research provides new design principle for water-splitting catalysts
  

  Scientists have long known that platinum is by far the best catalyst for splitting water molecules to produce hydrogen gas. A new study by Brown University researchers shows why platinum works so well -- and it's not the reason that's been assumed. The research, published in ACS Catalysis, helps to more

• Tungsten suboxide improves the efficiency of platinum in hydrogen production
  

  Researchers presented a new strategy for enhancing catalytic activity using tungsten suboxide as a single-atom catalyst (SAC). This strategy, which significantly improves hydrogen evolution reaction (HER) in metal platinum (pt) by 16.3 times, sheds light on the development of new electrochemical cat more

• Platinum-graphene fuel cell catalysts show superior stability over bulk platinum
  

  Films of platinum only two atoms thick supported by graphene could enable fuel cell catalysts with unprecedented catalytic activity and longevity, according to a study published recently by researchers at the Georgia Institute of Technology. Platinum is one of the most commonly used catalysts for fu more

• Helpers of all sizes for analysts
  

  Geologists analyze soil samples, the oil industry studies crude oil, and the steel industry wants to know the composition of slag. These are completely different fields, but all begin the analysis process with a high-temperature fusion treatment of t more

The Chemistry of Diamond Rings

Diamonds might purportedly be ‘a girl’s best friend’, but they’re also quite interesting from a chemical perspective. You could be forgiven for thinking that there’s not a whole lot to them; after all, they’re simply one of the possible forms of carbon, formed at high pressure beneath the Earth’s su more

The Chemical Elements of a Smartphone

There are an isolated few graphics online that look at elements involved in the manufacture of a smartphone – for example, this ‘Periodic Table of iPhones’ – but there’s actually remarkably little easily accessible information out there that details the specific compounds used for specific purposes more

Transition Metals

This graphic looks at some general properties of the transition metals – I had a little less space to work with than with the previous graphics, on account of the large number of elements that the transition metals encompass, but hopefully what’s included is still of use. more

• Fabrication of single-chain nanoparticles through the dimerization of pendant anthracene groups via photochemical upconversion

  We report on the use of visible light as the driving force for the intramolecular dimerization of pendant anthracene groups on a methacrylic polymer to induce the formation of single-chain nanoparticles (SCNPs). Using a 532 nm green laser light source and platinum octaethylporphyrin as a sensitizer, more
