Summary: We report the layer-by-layer build-up of high-order harmonic generation (HHG) in artificially stacked transition metal dichalcogenides (TMDC) crystals. High-order harmonics up to the 19th order are generated by the interaction with a mid-infrared (MIR) driving laser. The generation of harmonics is sensitive to the number of layers and their relative orientation, with different stacking configurations showing different harmonic intensities.

Summary: Hardware security is a major concern in the semiconductor industry, with billions of dollars in losses annually. Information security is also critically important for edge devices, which collect and transmit large amounts of data. Current silicon-based solutions are inadequate, inefficient, and vulnerable to machine learning attacks, leading to a need for innovation. 2D materials, such as graphene, have shown potential in addressing these security challenges through techniques like camouflaging and true random number generation.

Summary: High entropy oxide (HEO) is a new type of anode material for Li-ion batteries that allows for customized charge-discharge properties. However, the impact of a secondary phase has been overlooked. In this study, two types of Co-free HEOs were prepared, one with a plain cubic structure and the other with an additional tetragonal spinel oxide phase. It was found that the secondary phase improved the redox kinetics and reversibility of the electrodes. The cycling stability of the electrodes was also validated using density functional theory calculations. This study demonstrates for the first time the enhanced rate capability and cyclability of HEO electrodes induced by a secondary phase.
