  • Scientist Discovers New Oxidation State of Rhodium

    Mayara da Silva Santos, doctoral candidate at the University of Freiburg’s Institute of Physics, has discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for example, in catalytic converters for automobiles. more

  • Third-highest oxidation state secures rhodium a place on the podium

    Oxidation states of transition metals describe how many electrons of an element are already engaged in bonding, and how many are still available for further reactions. Scientists from Berlin and Freiburg have now discovered the highest oxidation state of rhodium, indicating that rhodium can involve more

  • New tech aims to drive down costs of hydrogen fuel

    Researchers from North Carolina State University have developed a new technique for extracting hydrogen gas from liquid carriers which is faster, less expensive and more energy efficient than previous approaches. “Hydrogen is widely viewed as a sustainable energy source for transportation, but there 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

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

  • Water instead of mineral oil

    Optical active substances made from chiral catalysis form the basis of many drugs. Expensive precious-metal catalysts are required for the chemical production, which due to their thermal instability decompose at high temperatures and can therefore only be used once. The innovative process of DexLeChem GmbH makes it possible for the first time to use these precious-metal catalysts made from rhodium, ruthenium or iridium more than once, without modifying them. At the same time, reaction occurs in aqueous solutions instead of mineral-oil-based solvents, which increases the sustainability of the process. This is a milestone in catalysis and a real opportunity for the pharmaceutical industry. more
