Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

Journal of Raman Spectroscopy, EarlyView.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.

Comparison of Enamel, Dentin, and the Dentin–Enamel Junction in Horse, Dog, Wild Boar, and Macaque Using Confocal Raman Microscopy

Journal of Raman Spectroscopy, EarlyView.
Confocal Raman microscopy was used to map the dentin–enamel junction (DEJ) across four mammalian species. Chemical maps highlighted variations in mineral (phosphate/carbonate) and organic (amide/CH) phase. These results provide a comparative Raman framework to link tooth microchemistry with species‐specific structure and function.

Image quality in forensic CT imaging

, 2018
What factors affect the diagnostic image quality in forensic computed tomography (CT) imaging? In this thesis I briefly present the main steps from CT scanning to diagnostics. The thesis is built on four core papers. The first paper focuses on reconstructions of a quality control phantom measurement series. Objective image quality descriptors (contrast

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

A Power‐Efficient Monte Carlo Framework for Nonlinear Light–Matter Interactions: In Silico Modeling of Spontaneous and Stimulated Raman Scattering in Turbid Media

Journal of Raman Spectroscopy, EarlyView.
Power‐efficient Monte Carlo modeling of nonlinear light–matter interactions in turbid media is demonstrated using Apple Silicon–accelerated photon transport. The Metal‐base framework enables accurate simulation of spontaneous and stimulated Raman scattering, revealing detection‐dependent SRS efficiency while providing a scalable, energy‐efficient ...
