An experiment at the Institut Laue-Langevin raises great hopes.
The health of millions of people is threatened by the presence of arsenic in their drinking water. In countries such as India, Bangladesh, Vietnam, Taiwan and Argentina, tens of millions of people drink untreated water containing levels of arsenic between ten and one hundred times higher than that recommended by the World Health Organisation ! Even in France, many sources of water, including mineral waters, will no longer satisfy new standards introduced on 1st January 2004 (which limit the concentration of arsenic in drinking water to 10 ìg L-1).
In order to decontaminate these water supplies, we urgently need to find an inexpensive and efficient method of trapping the arsenic. Studies have recently been conducted at the ILL into the capacity of calcite to capture arsenic. Unlike other substances such as manganese sand, iron oxides or ettringite, which though more efficient are much rarer and more expensive, calcite is in fact the main constituent of limestone and therefore an extremely common mineral.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
