The 2D material hexagonal boron nitride is so resistant to cracking that it defies a century-old theoretical description engineers still use to measure toughness, according to a study by Rice University and Nanyang Technological University in this week s issue of Nature.
In collaborative international effort, laser physicists at LMU have built the first hybrid plasma accelerator.
Particle accelerators have made crucial contributions to some of the most spectacular scientific discoveries of modern times, and greatly augmented our knowledge of the structure of matter. Now a team of laser physicists led by Prof. Stefan Karsch at the Ludwig-Maximilian University (LMU) in Munich and the Max Planck Institute for Quantum Optics, in cooperation with scientists based at the Helmholtz Centre in Dresden-Rossendorf (HZDR), the Laboratoire d Optique Appliquée in Paris (LOA), Strathclyde University in Glasgow and the DESY Electron Synchrotron in Hamburg, have now achieved a significant breakthrough in accelerator miniaturization. They have built the first compact two-stage plasma-based accelerator in which particles in a plasma wave initiated by a powerful laser are used to accelerate a beam of electrons.

Fluorinated compounds are an important group of compounds that are widely used in pharmaceuticals, agricultural chemicals, functional resins, and organic electronic materials. In particular, perfluorinated compounds with multiple carbon-fluorine bonds are attracting attention because of their high thermal and chemical stability and various excellent properties such as water and oil repellency and chemical resistance. C-F bonds are extremely strong; hence, their transformation under mild conditions is difficult, and the selective activation of a specific C-F bond from among multiple C-F bonds in perfluorinated compounds has not been achieved, explains Prof. Makoto Yasuda, corresponding author of the study.
