  • Special coating protects steel from hydrogen ‘attack’

    Regeneratively produced hydrogen is an ideal energy carrier, which will be used in future applications as fuel cells and cars and will supplement natural gas as an energy source. But atomic hydrogen often induces brittle behavior in metals at high temperatures. Lukas Gröner of the Fraunhofer IWM, Mi more

  • Deep decarbonization of industry is possible with innovations

    On behalf of the EU Commission, Fraunhofer ISI explored what contribution individual technologies can make to decarbonizing industry and how to support them. The study shows that it is possible to cut emissions by 95% by 2050. However, this requires innovative carbon-neutral technologies and compreh more

  • Fibers from old tires can improve fire resistance of concrete

    A new way of protecting concrete from fire damage using materials recycled from old tyres has been successfully tested by researchers at the University of Sheffield. The team used fibres extracted from the textile reinforcement commonly embedded into tyres to guarantee their performance. Adding thes 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

The Elemental Compositions of Metal Alloys

Today’s post looks at an aspect of chemistry we come across every day: alloys. Alloys make up parts of buildings, transport, coins, and plenty of other objects in our daily lives. But what are the different alloys we use made up of, and why do we use them instead of elemental metals more

Steel

Steel winding tower. Steel is an alloy consisting mostly of iron , with a carbon content between 0.2 and 1.7 or 2.04% by weight (C:1000–10,8.67Fe), depending on grade. Carbon is the most cost-effective alloying material for iron, but various ... more
