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.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
