Synergistic Integration of Fe–N4 Single‐Atom Sites and Directionally Aligned Electrode Architecture for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Science, EarlyView.
A directionally ice‐templated sulfur cathode integrated with atomically dispersed Fe–N4 catalytic sites is developed for high‐performance lithium–sulfur batteries. The structure–catalysis synergy accelerates Li+ transport and polysulfide conversion, leading to high sulfur utilization and stable long‐term cycling performance.

Selenocyanate Driven Organic Cations Homogenization in Wide‐Bandgap Perovskite

open access: yesAdvanced Energy Materials, EarlyView.
Selenocyanate pseudohalide doping stabilizes 1.66 eV wide‐bandgap formamidinium (FA)‐based perovskite lattices via strong FA+ hydrogen bonding and matched ionic radii. Uniform cation distribution and suppressed ion migration reduces defect losses, delivering >24% single‐junction efficiency and 32.66% perovskite/silicon tandem performance with ...

Multiwavelength Brillouin-Thulium Fiber Laser

open access: yesIEEE 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.

Light bullet generation via stimulated Brillouin scattering

open access: yesAPL Photonics
We 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.
