Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...

Mid-infrared Raman sources using spontaneous Raman scattering in germanium core optical fibers
Mid-infrared Raman sources based on spontaneous Raman scattering have been demonstrated in a 15 µm diameter glass-clad crystalline germanium optical fiber and in a germanium-wire.

Reinforcing Oxygen Activation of Spinel Oxide via Mn─O Covalency Engineering for VOCs Oxidation
A MnCo spinel catalyst with weakened Mn─O covalency was synthesized via a hard‐template method. The reduced Mn─O covalency facilitates localized electron redistribution, promoting the activation of both molecular oxygen and lattice oxygen, and thereby enabling the efficient and complete oxidation of VOCs (ethyl acetate, toluene, and propane).

Electrochemical Modulation of Laser‐Induced Covalent Functionalization of Graphene
Photoelectrochemical functionalization of graphene introduces the electrochemical potential as an additional parameter for the laser‐induced covalent modification of graphene. Tuning of the potential allows for amplification or suppression of the functionalization reaction with constant laser parameters, which enables in situ Raman analysis of ...

We measure spontaneous Raman scattering (SRS) effects in C-band and observe trench-assisted MCF is robust to SRS noise, making it possible to run quantum channels in the neighboring and/or the same core as data channels.

Ultrabroadband two‐beam coherent anti‐Stokes Raman scattering and spontaneous Raman spectroscopy of organic fluids: A comparative study [PDF]
Spontaneous Raman spectroscopy is a well‐established diagnostic tool, allowing for the identification of all Raman active species with a single measurement. Yet, it may suffer from low‐signal intensity and fluorescent background.
