From aircraft to electronic devices, and even in Formula One cars, stress is the main cause of degraded material performance and mechanical failure in applications incorporating thin films and coatings.

The lattice damage in a diamond crystal irradiated with 9-MeV carbon ions has been studied as a function of fluence and layer depth by Raman and photoluminescence micro-spectroscopies.
The effective redirection of spin waves and their local control are among the main challenges faced by the emergent field of magnon spintronics. To solve the problem Lara et al. introduce a breakthrough technology for communication and signal processing using spin waves localized at the edges of magnetic nanostructures.

This tutorial review presents an overview of the basic theoretical aspects of two-dimensional (2D) crystals. We revise essential aspects of graphene and the new families of semiconducting 2D materials, like transition metal dichalcogenides or black phosphorus.
At the ultimate thinness level, electrons in two-dimensional van der Waals field-effect transistors (FETs) are particularly vulnerable to interactions with the surrounding environment, leading to strong fluctuations of the current output.
