Photobiomodulation-based (PBM-based) therapies show promising results in mucositis and dermatitis treatment by stimulating wound healing mechanisms such as cell proliferation and migration. The aim of the present study is to investigate the in vitro effects of CareMin650 on the proliferation and migration of two different types of cells, namely can...

We report here a novel experimental scheme for the measurement of strain that utilizes a simple intensity based interrogation system through use of optical fibers. Corresponding to splicing of a multimode fiber between two single mode fibers, the transmittance was measured by subjecting them to strain at multi points. The measurements corresponding...
Les fuites de méthane soulèvent à la fois des problématiques environnementales et sécuritaires, particulièrement dans l'industrie pétrolière. Le contrôle de panaches en temps réel permettrait de prévenir d'éventuels drames humains et catastrophes écologiques. Dans ce contexte, un volet du projet NAOMI, impliquant TOTAL E&P et l'ONERA, vise à dévelo...

The study incorporates the urea detection in non-enzymatic urea samples and enzymatic urea-urease samples utilizing the phenomenon of surface plasmon resonance (SPR)/localized surface plasmon resonance (LSPR) realized on the core of a multimoded optical fiber. The designed bio-sensor, primarily a refractive index sensor well operates for the urea d...
We report on the experimental generation of spatially multiplexed picosecond 40-GHz pulse trains at telecommunication wavelengths by simultaneous intra-modal multiple four wave mixing and intermodal cross-phase modulation in km-long bi-modal and 6-LP-mode graded-index few-mode fibers. More precisely, an initial beat-signal injected into the fundame...

Local tissue oxygenation determines the relationship between the supply and the demand for oxygen by the tissue and it is an important indicator of the physiological or pathological condition of the tissue. Moreover, some therapeutic methods strongly depend on the oxygen content of the tissue. In photodynamic therapy, when molecular oxygen is prese...

An optical sensor composed of a circular cylindrical fiber surrounded by graphene layer is investigated. The thin layer of graphene is located at the core–cladding interface. The cladding is an aqueous material. The conductivity (σ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \use...

This study focuses on the tilted fiber Bragg gratings. The paper describes the method of their inscription into optical fiber using the Talbot interferometer and KrF excimer laser system. The method allows precise selection of the resonant wavelengths and tilt angles of the created structures in a wide range of values. In course of the study, an or...

To date, sunlight driven photocatalytic process for wastewater treatment is a great challenge. Herein, the photocatalytic methylene blue (MB) dye degradation activity of silver vanadate nanobelts has been enhanced using concentrated sunlight irradiation. The MB dye degradation factor in normal and concentrated sunlight irradiation is 0.57 and 0.25 ...
