  • Methane to syngas catalyst: two for the price of one

    Hokkaido University researchers have created an improved catalyst for the conversion of methane gas into syngas, a precursor for liquid fuels and fundamental chemicals. Syngas, also known as synthesis gas, is a mixture made primarily of carbon monoxide and hydrogen and is used to manufacture polymer more

  • Catalyst advance could lead to economical fuel cells

    Researchers at Washington State University have developed a new way to make low-cost, single-atom catalysts for fuel cells -- an advance that could make important clean energy technology more economically viable. Hydrogen fuel cells are critical for the clean energy economy as they are more than two more

  • Perfect inversion

    Perfectly inverting complex structures is of great technical importance. Researchers at ETH have now succeeded in turning the magnetic and electric structure of materials into their opposites using a single magnetic field pulse. Whenever it gets unpleasantly loud, active noise reduction has been use more

Colours of Transition Metal Ions in Aqueous Solution

This graphic looks at the colours of transition metal ions when they are in aqueous solution (in water), and also looks at the reason why we see coloured compounds and complexes for transition metals. This helps explain, for example, why rust (iron oxide) is an orange colour, and why the Statue of L more

Testing for Cations

A previous post looked at the colours of transition metals, and the origin of their colours – this graphic, on the other hand, looks at how transition metals (and some non-transition metals) can be identified by the precipitates they form with sodium hydroxide and ammonia solutions. I’m going to kee 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
