Journal of Raman Spectroscopy, EarlyView.We propose an UV photobleaching pretreatment to reduce the strong luminescence in the Raman spectra of plastic samples. Our protocol proves its efficiency whatever the luminescence origin (from the pigments or from a surface biofilm) but requires a careful optimization of the illumination conditions (UV wavelength, time, humidity) to reach the ...

Journal of Raman Spectroscopy, EarlyView.We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater

3D Surface Profiling via Direct End‐to‐End Regression With a Photonic Geometric Sensor
Laser &Photonics Reviews, EarlyView.Measurements of microscale surface patterns are essential for quality control across semiconductor and biomedical industries, yet the development of miniaturized, intelligent systems remains constrained by the complexity and bulkiness of conventional benchtop metrology.

Nonlinear Resonance Modulation in Single‐Crystalline VO2‐Integrated Si Ring Resonator
Laser &Photonics Reviews, EarlyView.This work first demonstrates a single‐crystalline VO2–Si hybrid ring resonator. The epitaxial lift‐off process enables high‐quality VO2 integration on the dissimilar Si photonic platform. The high‐quality VO2 film exhibits exceptional nonlinear resonance modulation and a steep optical transition across the metal‐insulator transition. ABSTRACT The metal‐

Quantifying Dual‐Color Photopolymerization in Xolography via Raman Spectroscopy
Journal of Polymer Science, EarlyView.A dual‐wavelength Raman spectroscopy workflow is presented for the quantitative assessment of dual‐color photoinitiators. Contrast and efficiency parameters are extracted from in situ curing curves and spatial Raman mapping is used to find inhomogeneities in printed objects.

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.
