Acrylamide (AA)is a substance that has found widespread application in industry, e.g. for the purification of drinking water and in food packaging. Due to its toxicological properties, legal limits have been set both for drinking water and for migration into food.
Following a request of the participants of the European Workshop on "Analytical methods for the acrylamide determination in food", the Institute for Reference Materials and Measurements (IRMM) of the European Commission’s Directorate General Joint Research Centre (DG JRC) organised an inter-laboratory comparison test on the determination of AA in butter cookies and crispbread samples. One goal of the collaborative trial was the evaluation of the performance of laboratories at an AA level close to the limit of quantification (LOQ) . Another goal was the elucidation of the most critical steps in the applied analysis protocols. For that purpose, a raw bread extract and a spiked bread extract were shipped with the food samples. The set of samples was completed by AA standard solutions, which were prepared by dissolution of solid AA in appropriate solvents.
The study was a dedicated collaborative trial and was free of charge for the participants. It was announced via the Directorate Health General and Consumer Protection (DG SANCO) to the national food authorities of EU Member States and EU Candidate Countries. Additionally all participants of the above-mentioned workshop were informed by email. Information concerning the application procedure for the study was also available on the homepage of the Food Safety and Quality Unit (FSQ) of IRMM.

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...
