  • Nickel wraps itself in ultrathin carbon mantle

    Scientists have been exploring a promising way of producing layers of graphene with particularly few defects. This coveted carbon allotrope spontaneously forms on nickel surfaces on which carbon has previously been deposited. The extremely high quality of the graphene produced and the relatively low more

  • Nanostructuring increases efficiency of metal-free photocatalysts by factor eleven

    Polymeric carbon nitrides exhibit a catalytic effect in sunlight that can be used for the production of hydrogen from solar energy. However, the efficiency of these metal-free catalysts is extremely low. A team at the Tianjin University in China, in collaboration with a group at the Helmholtz-Zentru more

  • Production of solar fuels inches closer with news discovery

    Caltech researchers have made a discovery that they say could lead to the economically viable production of solar fuels in the next few years. For years, solar-fuel research has focused on developing catalysts that can split water into hydrogen and oxygen using only sunlight. The resulting hydrogen more

The Compositions of U.S. Coins

In this month’s Periodic Graphics in Chemical & Engineering News magazine, we’re looking at the compositions of U.S. coins, as well as some of their quirky history. more

The Metals in UK Coins

In the wake of the recent announcement of a new £1 coin to be introduced in 2017, today’s post looks at some of the metals present in the coins of the United Kingdom. All of these coins are produced using alloys, or mixtures of metals; the main metals used include copper, nickel, zinc and iron. The 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
