This month’s issue focuses on light metals, and includes:
- Grinding them down: A report from The Commonwealth Scientific and Research Organisation into grinding technologies available to the minerals industry. Covering the advantages and limitations of IsaMills, Tower and Detritor mills in depth, along with their ability to produce fine grain particles.
- Melting moments: Rheoforming melt processing technologies under development at the Brunel Centre for Advanced Solidification Technology. This group of techniques can be used for aluminium and magnesium alloys. The article discusses twin-screw melt-conditioning devices and the potential advantages of developing these new technologies.
- Titanium – 21st century metal in transition: High strength, lightweight titanium may soon become a commodity metal. In order to meet government targets to reduce carbon emissions, titanium could be the material of choice for aircraft and car components as it is lighter than steel. The current status in terms of production methods and their capacity to meet demand is also discussed.
The mining feature in May’s issue presents the findings of laboratory and real life experiments into the use of bone meal for the remediation of old mines. Dr Eva Valsami-Jones from the Natural History Museum in London, UK, discusses the environmental impact of mining and the lack of incentives to clean contaminated land. Bone meal could provide an environmentally friendly solution and test results have proved successful in the remediation of land contaminated with a number of metals, including zinc, aluminium, lead and copper.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
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...
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...
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...
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...
