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.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
