Solvent-based waterproof mascara and nail polish require their containers to provide high barrier performance in terms of water vapor, aroma and solvents in order to minimize weight loss. Beyond this barrier requirement, Selar® PA can provide superior optics, a glossy and scratch resistant surface, excellent solvent and chemical resistance and excellent compatibility with decoration methods such as varnishing, printing and metallization.
New and enhanced grades of DuPont Selar® PA are targeted for use as a high barrier resin for demanding solvent-based applications such as waterproof mascaras and nail polish containers, meeting industry demands for performance, aesthetics and sustainability.
New impact-modified DuPont™ Selar® PA 7003, designed for use in waterproof mascara tubes, provides increased drop impact resistance (as illustrated in chart above) and enhanced processability versus incumbent materials.
Selar® PA 3426R, for use in nail polish containers, combines all of the above attributes with superior transparency to rival the clarity and chemical inertness of glass, without its weight and brittleness. Alternatively, new impact-modified Selar® PA 7003, designed for use in waterproof mascara tubes, provides increased drop impact resistance and enhanced processability versus incumbent materials. Its enhanced wall thickness distribution creates the potential for manufacturers to further reduce the wall thickness of their containers, thereby decreasing production costs. Such benefits have recently seen the new material gaining qualification for use in its mascara packaging by L’Oreal’s Expertise Packaging Center in France.

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...
