Spontaneous Raman scattering in SDM fibers

Optics Letters
Spontaneous Raman scattering (SpRS) is a weak nonlinear effect particularly relevant to classical-quantum coexistence transmission and sensing applications. In classical transmission, the relevant Raman effect is stimulated Raman scattering (SRS), and recent studies have examined it in space-division multiplexing (SDM) fibers. An

N‐Doping Activated Presodiation Enhances Sodium‐Ion Provision in Hard Carbon Anodes

Advanced Science, EarlyView.
Introducing pyrrolic‐N sites enables efficient presodiation and stronger PF6− capture, thus pre ‐ forming a robust inorganic‐rich SEI layer in hard carbon anodes. ABSTRACT Hard carbon (HC) is considered the most promising anode material for commercial sodium‐ion batteries (SIBs), yet it still faces critical challenges such as low initial Coulombic ...
