High index contrast photonic platforms for on-chip Raman spectroscopy [PDF]
, 2019 Nanophotonic waveguide enhanced Raman spectroscopy (NWERS) is a sensing technique that uses a highly confined waveguide mode to excite and collect the Raman scattered signal from molecules in close vicinity of the waveguide. The most important parameters

Improving spatial resolution of confocal Raman microscopy by super-resolution image restoration [PDF]
, 2016 A new super-resolution image restoration confocal Raman microscopy method (SRIR-RAMAN) is proposed for improving the spatial resolution of confocal Raman microscopy. This method can recover the lost high spatial frequency of the confocal Raman microscopy

Frequency shifts in stimulated Raman scattering [PDF]
, 1980 The nonresonant contributions to the nonlinear susceptibility χ(3) produce a frequency chirp during stimulated Raman scattering. In the case of transient stimulated Raman scattering, the spectrum of the generated Stokes pulse is found at higher ...

X-Ray Flares in the Long-term Light Curve of Low-luminosity Active Galactic Nucleus M81*
The Astrophysical Journal, 2023 Most active galactic nuclei at the center of the nearby galaxies have supermassive black holes accreting at sub-Eddington rates through hot accretion flows or radiatively inefficient accretion flows, which efficiently produce jets.

Study of dynamical heterogeneities in colloidal nanoclay suspensions approaching dynamical arrest
Scientific Reports, 2017 The dynamics of aqueous Laponite clay suspensions slow down with increasing sample waiting time (t w ). This behavior, and the material fragility that results, closely resemble the dynamical slowdown in fragile supercooled liquids with decreasing ...
