Nano-sized silver particles open way to new breed of antimicrobial materials
Scientists can now incorporate silver particles into polypropylene to produce an anti-microbial material that could be used in anything from carpets, to napkins and surgical masks.
Silver has been medically proven to kill over 650 disease-causing organisms in the body and is also very safe. By combining silver and polypropylene to produce an organic-inorganic fibre, researchers have produced the first safe, anti-microbial fibre with a wide range of possible applications.
Polypropylene fibre is one of the most widely used synthetic fibres in the textile industry because it is cheaper and stronger than other synthetic fibres. Researchers have demonstrated, in a paper to be published in the July issue of Polymer International, available online in June, that they can produce two types of fibres both with silver particles distributed evenly along the length of the fibre.

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

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...
