  • New 'blue-green' solution for recycling world's batteries

    Rice University researchers literally have a solution to deal with the glut of used lithium-ion batteries left behind by the ever-increasing demand for electric vehicles, cellphones and other electronic devices. The Rice lab of materials scientist Pulickel Ajayan used an environmentally friendly dee more

  • Powerful X-ray beams unlock secrets of nanoscale crystal formation

    High-energy X-ray beams and a clever experimental setup allowed researchers to watch a high-pressure, high-temperature chemical reaction to determine for the first time what controls formation of two different nanoscale crystalline structures in the metal cobalt. The technique allowed continuous stu more

  • Sustainable 'nano-raspberry' to neutralize poisonous carbon monoxide

    Scientists from the Nagoya Institute of Technology (NITech) in Japan have developed a sustainable method to neutralize carbon monoxide, the odorless poison produced by cars and home boilers. Traditionally, carbon monoxide needs a noble metal - a rare and expensive ingredient - to convert into carbon 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
