High speed nanotribology with quartz crystal resonators via Atomic Force Microscopy [PDF]
arXiv, 2013 Friction measurements in the range of several meters per second are still of great interests. With the atomic force microscopy (AFM), the oscilaltion situation of the quartz crystal resonators of 3MHz resonance frequency are studied. And the oscillation speed could reach up to several m/s.

Advanced Functional Materials, EarlyView.Off‐centering of cations in pavonite‐structured Ag1.75InSb5.75Se11 (AISS) breaks crystal symmetry, inducing Rashba‐like band splitting and high band degeneracy, thus enhancing Seebeck coefficients. Soft bonds between off‐centered cations and Se atoms increase phonon scattering, achieving low lattice thermal conductivity (0.22 W m−1K−1 at 723 K). Doping

Inter‐Layer Diffusion of Excitations in 2D Perovskites Revealed by Photoluminescence Reabsorption
Advanced Functional Materials, EarlyView.Inter‐layer diffusion of photoexcitations is monitored in thin films of the 2D perovskite (PEA)2PbI4 by tracking time‐dependent changes in photoluminescence spectra induced by photon reabsorption effects. A low out‐of‐plane excitation diffusion coefficient of 0.26 × 10−4 cm2 s−1 is determined through 1D diffusion modeling.

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level
Advanced Functional Materials, EarlyView.High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...
