Ion‐Confinement‐Assisted Erasure Purifies Oxidized MXene for Reuse
Advanced Science, EarlyView.An erasure‐purification strategy removes surface‐derived TiO2 from oxidized Ti3C2Tx MXene by ion‐confinement‐induced interfacial conversion to soluble titanates, followed by brief acid washing. The scalable process enables approximately 70% material recovery, restores electrical conductivity, and recovers functional performance, including high ...

Advanced Science, EarlyView.Biomass‐derived lignin is used as a sustainable precursor to synthesize Mo single atoms anchored on a nitrogen‐coordinated carbon framework. As the Mo structure transitions from MoC clusters to isolated single‐atom sites, oxygen evolution reaction (ORR) activity progressively improves.

Multiwavelength Brillouin-Thulium Fiber Laser
IEEE Photonics Journal, 2014 We demonstrate the first multiwavelength Brillouin-thulium fiber laser (BTFL) with wavelengths near 1.97 μm. The multiwavelength fiber laser was realized based on stimulated Brillouin scattering and nonlinear polarization rotation effects.

Advanced Science, EarlyView.This study investigates acoustic phonon‑carrier coupling in FAxMA1−xPbBr3 single crystals using time‑domain Brillouin scattering. The results show that increasing the FA content in FAxMA1−xPbBr3 single crystal reduces both the elastic constant and the intrinsic carrier mobility governed by the acoustic phonon‑carrier coupling.

Light bullet generation via stimulated Brillouin scattering
APL PhotonicsWe propose an all-optical approach to generating space–time wave packets in a multimode slab waveguide via the multilevel interband stimulated Brillouin scattering process. Two pump sources and a single-mode signal are fed into the waveguide.

Lattice Dynamics Across the High‐Pressure Phase Transition in CrTe
Advanced Electronic Materials, EarlyView.ABSTRACT High‐pressure physics provides a powerful means of tuning interatomic interactions, enabling the discovery of novel structural and physical phenomena in materials. Chromium telluride, a transition metal chalcogenide, is particularly responsive to such external stimuli, exhibiting a broad spectrum of pressure‐, temperature‐, and stoichiometry ...
