Afghanistan's natural resources include significant deposits of metals such as gold, silver, copper and zinc; precious and semi-precious stones including lapis, emerald and azure; and coal, natural gas and oil. Accurate geological surveys of the country's mineral resources are crucial to locating deposits and advising potential investors, but the AGS has seen decades of decay and neglect.
Michael Watts, an analytical chemist with the British Geological Survey, is deputy leader of a team that has just left for Afghanistan to install a geochemistry laboratory. ‘We have to take a very pragmatic, low-tech approach,’ Watts told Chemistry World magazine. ‘We are establishing a very basic infrastructure.’ The main piece of equipment for the laboratory will be a spectrophotometer, used to test water for the presence of zinc, nickel and copper.
If the AGS can start to function efficiently once again, the future is potentially bright: donors such as the World Bank are waiting in the wings with substantial investment to help develop Afghanistan’s mineral trade.

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...

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...
