Fiber Vector Light-Field-Based Tip-Enhanced Raman Spectroscopy.

Tip-enhanced Raman spectroscopy (TERS) has been extensively employed to investigate the light-matter interaction at the nanoscale. However, the current TERS strategies lack the ability to excite the low-background inhomogeneous electromagnetic field with significant enhancement of electric field, electric field gradient, and optomagnetic field, simultaneously. To overcome this, we developed a fiber vector light-field-based TERS strategy aimed at exploring the multipole Raman scattering processes of molecules.

Nickel-Doping Induced Oxygen Vacancies in MnO Hollow Cube with Enlarged Interlayer Spacing for Stable Sodium Ions Storage.

Intrinsic low conductivity, poor structural stability, and narrow interlayer spacing limit the development of MnO in sodium-ion (Na) supercapacitors. This work constructs the hollow cubic Mn-PBA precursor through an ion-exchange process to in situ obtain a hollow cubic H-Ni-MnO composite with Ni doping and oxygen vacancies (O) via a self-oxidation strategy. Experiments and theoretical calculations show that the hollow nanostructure and the expanding interlayer spacing induced by Ni doping are beneficial for exposing more reactive sites, synergistically manipulating the Na transport pathways.
