Dutch research has revealed that bone cement containing antibiotics can effectively control infections around prostheses but only during the first few days after the implantation. For the past 30 years bone cement, which affixes hip and knee prostheses to the bone, has contained antibiotics and from the start, the usefulness of this has been contested.
In a laboratory set-up, Hans Hendriks discovered that in the immediate vicinity of the antibiotic-containing bone cement, the antibiotic concentrations are particularly high. However, this is predominantly during the first few days after the application of the cement and the long-term release of the antibiotic seems to be less effective.
Hendriks investigated the release of antibiotics under simulated real-life conditions. He first of all investigated the antibiotic concentration in the cavity between the surface of the bone and the bone cement. In the human body this cavity is about 0.2 mm wide.

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...

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...
