High power cladding-pumped Raman fiber laser with true single-mode output at 1660 nm

, 2006
We report a 10 W continuous-wave cladding-pump Raman fiber laser with single-mode output at 1660 nm pumped by a high-power Er:Yb fiber amplifier. The laser threshold was 6.5 W and its slope efficiency was 67%

Breaking the Activity–Stability Scaling in RuO2 via Single‐ and Dual‐Doping Strategies

EcoEnergy, EarlyView.
Single and dual heteroatom doping redefines RuO2 for acidic oxygen evolution by synergistically tuning the electronic structure, lattice stability, and reaction pathways. Although single dopants optimize specific catalytic properties, dual dopants overcome the activity–stability trade‐off through cooperative electronic and geometric regulation ...

Asymmetric Dual‐Electron Bridge Via Gradient Orbital Coupling for Robust Alkaline Oxygen Evolution in Low‐Iridium Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...

Tuning Stability and Optoelectronic Properties of CsSnI3 Via Rare‐Earth Doping

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sn‐based halide perovskites are promising optoelectronic materials but are limited by poor stability. Thus, rare‐earth elements (RE) doping in CsSnI3 addresses this limitation, significantly enhancing thermodynamic, mechanical, and chemical stability, while simultaneously tuning electronic characteristics and modulating optical responses in the ...

High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...
