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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
