In this study we report on the efficiency of a furane-indole-chromenone-based organic derivative () as a photocatalyst in the α-arylation of enol acetate upon LED irradiation at 405 nm, and as a photoinitiator/photocatalyst in the free radical polymerization of an acrylate group in the presence of -(4--butylphenyl)iodonium hexafluorophosphate (Iod) as an additive, or in the presence of both Iod and ethyl-4-(dimethyl amino) benzoate (EDB) under LED irradiation at 365 nm. The photochemical properties of this new light-sensitive compound are described, and the wide redox window (3.27 eV) and the high excited-state potentials / (+2.64 V vs. SCE) and / (-2.41 V vs. SCE) offered by this photocatalyst are revealed. The chemical mechanisms that govern the radical chemistry are discussed by means of different techniques, including fluorescence-quenching experiments, UV-visible absorption and fluorescence spectroscopy, and cyclic voltammetry analysis.

Visible light has been considered to have minimal impact on the skin. However, the increasing use of electronic devices has led to a significant increase in exposure to visible light, especially blue light. We measured the irradiance (mW/cm) and estimated dose (J/cm) of visible light and blue light emitted from various electronic devices including smartphones, tablets and computers.

Photothermal conversion can promote plastic depolymerization (chemical recycling to a monomer) through light-to-heat conversion. The highly localized temperature gradient near the photothermal agent surface allows selective heating with spatial control not observed with bulk pyrolysis. However, identifying and incorporating practical photothermal agents into plastics for end-of-life depolymerization have not been realized.

This in-vitro study assessed the influence of the shade of human teeth on the transmission of near-infrared light. A total of 40 teeth were used. After cleaning the root surface and removing cementum, the teeth were sectioned into slices 3 mm thick, with each comprising a portion of the crown (enamel-dentine (ED)) and of the root (dentine only).

Because of its benign nature and rarity, circumscribed choroidal hemangioma (CCH) often receives limited attention, leading to a high rate of misdiagnosis and a lack of standardized treatment protocols. We provide a thorough clarification of the demographics, clinical features, diagnosis, management, and prognosis of CCH. We conducted a systematic search of the PubMed, EMBASE, and Ovid databases up to December, 2023, to identify relevant studies.
