Putting antibacterial coatings on hip and knee implants and biomedical devices such as catheters could cut infection rates following surgery and significantly reduce health care costs and improve quality of life for patients, researchers at the University of South Australia have found.
A significant number of hip and knee implants are prone to infection after surgery and in many cases are not amenable to treatment with antibiotics, according to Hans Griesser, Professor of Surface Science and Deputy Director of UniSAs Ian Wark Research Institute.
"For patients in this situation it may be necessary to remove the implant from the infected site, cleanse the wound and undergo replacement surgery within a short time after original implantation, causing significant trauma, especially for the elderly," Professor Griesser said.

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...
