Summary:
Research shows that it is possible to produce copper about 4 times stronger than commercial material – and doing so while also having a ductile material. As the thermal and electrical conductivity are also good, the manufacturing of, for example, electrical conductors with improved mechanical properties looks promising.

The strength of metal depends on the microstructure – the finer the structure the stronger the metal. But one may wonder if this fundamental principle also applies to extremely fine structures?

Materials scientists worldwide have taken up this challenge and now a Chinese-Danish research collaboration has lead to a break-through in the understanding. The results are scientifically important, but also of interest to technology.

As expected, the strength of copper material increases when the structure becomes finer but when the structure dimension becomes smaller than 15 nanometers (1 nm = 10-6 mm) the metal unexpectedly becomes softer. The physical processes giving rise to this unusual softening have also been identified based on electron microscopy studies of the structure.

Super strong nanometals are perfect for continuation of the research collaboration between China and Denmark and their exploitation in practical applications are indeed promising.

3D Printed Instruments Make Sweet Music in Sweden

Reuters - Innovations Video Online (Oct. 23, 2014) — Students from Lund University's Malmo Academy of Music are believed to be the world's first band to all use 3D printed instruments. The guitar, bass guitar, keyboard and drums were built by Olaf Diegel, professor of product development, who says 3D printing allows musicians to design an instrument to their exact specifications.

Chameleon Camouflage to Give Tanks Cloaking Capabilities

Reuters - Innovations Video Online (Oct. 22, 2014) — Inspired by the way a chameleon changes its colour to disguise itself; scientists in Poland want to replace traditional camouflage paint with thousands of electrochromic plates that will continuously change colour to blend with its surroundings. The first PL-01 concept tank prototype will be tested within a few years, with scientists predicting that a similar technology could even be woven into the fabric of a soldiers' clothing making them virtually invisible to the naked eye.
