Hybrid Perovskite‐Photovoltaic and Solar‐Thermal Harvesting
Advanced Science, Volume 12, Issue 42, November 13, 2025.This study presents a hybrid solar energy harvesting concept that integrates a semi‐transparent perovskite solar module with a thermal collector. High‐energy photons generate electricity at 14.3% efficiency, while ≈55% of low‐energy photons provide heat.

Small Structures, Volume 6, Issue 11, November 2025.A novel six‐step strategy is developed for fabrication of durable stochastically hierarchical superhydrophobic boiling interfaces. The engineered interfacial properties effectively mitigate the loss of superhydrophobicity that occurs on copper during long‐term boiling, overcoming a key barrier to practical deployment in advanced phase change cooling ...

100 W all fiber picosecond MOPA laser
Optics Express, 2009 A high power picosecond laser is constructed in an all fiber master oscillator power amplifier (MOPA) configuration. The seed source is an ytterbium-doped single mode fiber laser passively mode-locked by a semiconductor saturable absorber mirror (SESAM). It produces 20 mW average power with 13 ps pulse width and 59.8 MHz repetition rate.

Chiral Lasing Emission from a Simple Two‐Unit Supercell Metasurface
Laser &Photonics Reviews, Volume 19, Issue 20, October 20, 2025.Circularly polarized light (CPL) sources are vital for various applications, yet narrow‐linewidth chiral lasing with a high degree of circular polarization (DCP) remains challenging. This study demonstrates narrow‐linewidth chiral lasing using a two‐unit supercell metasurface. The in‐plane symmetry breaking induces spin splitting of the Γ0‐BIC into Γ±1
