LIER (INRETS Road Equipment Test Laboratory) of France uses state-of-the-art technology to accredit road-safety devices. Clients use the services of LIER to develop and improve their road-safety products with the aim of obtaining both French and foreign accreditation, especially with respect to the new EN1317 European standard.
LIER is the European leader in the regulatory crash testing of different forms of road-side safety barriers or VRS (Vehicle Restraint Systems). It is the only laboratory in France to conduct tests on road-side restraint devices (guard rails, crash cushions, guard-rail end terminals, etc.) as well as any other equipment located on the sides of roads and motorways that is dedicated to protecting road users. These devices, subjected to numerous tests and inspections, are primarily intended to avoid damage to – and the consequences of – a vehicle accidentally leaving the road, and also to protect both those people travelling in the vehicle in question and the other road users in the immediate vicinity. Clients include road-side equipment manufacturers, designers, distributors or installers, who most often belong to the steelmaking, building and public works sectors, but also to the plastics and wood sectors.
Accredited by the COFRAC (Comité Français d’Accréditation – French Accreditation Committee) for the ISO/CEI 17025 quality standard (general measures concerning calibration and test laboratories), LIER uses an in-house quality-assurance system and has set itself strict standards regarding the skills of its personnel as well as the laboratorys impartiality and independence. With more than 100 impact tests carried out each year on its site, LIERs experience is so far based on approximately 950 tests performed, using cars, buses or lorries of between 10 and 38 tonnes.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
