A Cardiff University research collaboration is working to recycle precious metals from road dusts and vehicle exhausts to create greener energy.
The innovative research by scientists from the School of Earth, Ocean and Planetary Science working with the University of Birmingham is to be featured at the Royal Society Summer Science Exhibition (2-5 July).
Catalytic converters which keep exhaust pollutants from vehicles down to an acceptable level all use platinum, however over the years the platinum is slowly lost through exhaust pipes. Dr Hazel Prichard, School of Earth Ocean and Planetary Science estimates that many kilogrammes of platinum is being sprayed onto streets and roads every year.
Dr Prichard said: “Platinum is a vital component not only of catalytic converters but also of fuel cells. Fuel cells are an important new source of clean energy. Platinum is a precious metal and resources are scarce and expensive. Our research is looking at ways of recycling platinum and other precious metals.”
Dr Prichard is working with her team to find locations where platinum is concentrated enough to recover in order to develop cost-effective and sustainable ways to re-use this finite resource. One prime target is the waste containers in road-sweepers.
The research collaboration is also exploring how food wastes, and ‘friendly’ bacteria can be used to create greener energy. Their goal is to see these techniques being applied to produce clean fuel cells to create reliable, greener energy whilst minimising waste.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
