Today's waste, tomorrow's fuel

Sustainable energy from urban waste

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.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
