Thermal Property Determination Using Optimization of One-side Known Radiant Exposure
… a surge in composite material usage. However, exposure to elevated temperatures poses a significant risk to these materials, especially in scenarios such as fires and high-temperature exhaust gas impingement. Despite limited or no visible damage, composite properties can undergo significant …

Unravelling novel molecular targets for photobiomodulation in human hair follicle towards the development of more effective light-based therapies for hair growth
… depending on the wavelength, power density, exposure time and optical properties of tissue and cells. Last decade experienced a growing rise of commercial devices for management of hair growth, where all of them are based on low levels of light resulting into photobiological, non-thermal …

Evaluation of multiple and single emission peak light emitting diode light curing units effect on the degree of conversion and microhardness of resin-based pit and fissure sealant
… 2 or 4 mm curing distances. The irradiance and radiant exposure received on the top/bottom surfaces of the samples were measured using the Managing Accurate Resin Curing-Resin Calibrator (MARC-RC) system. The samples were stored at 37°C for one hour. Then, the DC (n=3/surface) and KHN …

Beam profile characterization of light-emitting-diode curing units and its effect on polymerization of a resin-matrix composite
… The influence of distance on irradiance, radiant exposure (RE) and degree of conversion (DC) on the top and bottom surfaces of a RMC increment, using various LCUs, at two clinically relevant distances was investigated. Molar absorptivity of the photoinitiators present in the nano-hybrid …

Appearance and Spectroscopic Characterization of Automotive Coatings for Forensic Purposes
… identified by Raman spectroscopy. Finally, as UV exposure can alter the chemistry of automotive coatings over time, controlled artificial weathering of clear coats from two major manufacturers was performed at 55°C and 75% relative humidity (RH) with 100% ultraviolet (UV) radiation using the …
