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 ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking
Laser &Photonics Reviews, EarlyView.Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Extended Fused Carbazole-BODIPY, High Brightness NIR Organic Dyes. [PDF]
Angew Chem Int Ed EnglHighly fused boron‐dipyrromethene (BODIPY) with a strong donor group has been synthesized, and their photophysical behaviors fully characterized. They exhibit outstanding brightness for fluorophores emitting in the NIR region. Water‐soluble nanoparticles filled with one of these dyes demonstrate high efficiency as the NIR II visualization agent ...

Materials and Corrosion, EarlyView.This article examines the impact of externally introduced chromium compounds on the localized corrosion of 316 L stainless steel in acidic chloride environments such as hydrochloric acid. While the corrosion resistance of 316 L relies on the formation of a chromium‐rich passive oxide layer, industrial conditions may expose the steel to various chromium

Fabrication of optical planar waveguides in $KY(WO_4)_2$ by He-ion implantation [PDF]
, 2005 In this paper, planar waveguides produced by He-ion implantation have been demonstrated in undoped and Yb-doped KY(WO/sub 4/)/sub 2/ crystals. The effective refractive indices of guided modes in surface planar waveguides were measured by dark m-line ...
