Plasmon–Exciton–Driven Modulation of the Electronic and Optical Properties of MoS2 via Cayley Tree Fractal Nanostructures

Journal of Raman Spectroscopy, EarlyView.
This work investigates the change in optical and electronic properties of monolayer MoS2 through the coupling of its excitons and a plasmonic fractal structure. The formation of the heterostructure shows significant enhancement on the edge of the fractal pattern relative to off, owing to the enhanced electric field at the edge of the branches.

Evaluation of skin components by in vivo confocal Raman spectroscopy

A pele, o maior órgão do corpo, desempenha um papel crucial na proteção e na manutenção da homeostasia. A camada mais externa, o estrato córneo (SC), atua como uma barreira que previne a perda de água e protege contra fatores ambientais. Compreender as características individuais da pele é essencial para cuidados de beleza personalizados, permitindo ...

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

Journal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

Method Based on Continuous Artificial Dry and Humid UV Treatments to Reduce the Luminescence Background in the Raman Spectra of Plastics

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 ...

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms.
