• PETRA III shines a light on efficient production technique for a novel ‘green’ fertiliser
  

  A purely mechanical method can produce a novel, more sustainable fertiliser in a less polluting way. That is the result of a method optimised at DESY's light source PETRA III. An international team used PETRA III to optimise the production method that is an adaptation of an ancient technique: by mil more

• Beyond lithium: A systematic search for candidate materials for calcium-ion batteries
  

  Electric cars are the future; they will help reduce air pollution and end our dependence on fossil fuels. However, there is one glaring problem with this potentially disruptive technology: the availability of sufficient lithium (Li) to produce all these car batteries. The best rechargeable batteries more

• Monitoring the corrosion of bioresorbable magnesium
  

  ETH researchers have recently been able to monitor the corrosion of bioresorbable magnesium alloys at the nanoscale over a time scale of a few seconds to many hours. This is an important step towards accurately predicting how fast implants are resorbed by the body to enable the development of tailor more

The Chemistry of Sparklers

It’s Fireworks Night here in the UK tomorrow, which means fireworks (obviously), bonfires and sparklers. We’ve looked at fireworks in a previous post, so this time around it’s time to take a look at the chemicals that go into producing sparklers, and their various roles. In sparklers, there are thre more

Metal Ion Flame Test Colours Chart

This graphic looks at the colour of various metal and metalloid ions that occur during flame tests. Most people probably remember doing this experiment in school chemistry lessons, if not with the full range of ions shown here, but for the uninitiated a brief explanation of the origin of the colours 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
