Chalcogenide-based thin-film solar cell optimized for rear illumination and used for CO2 reduction is presented. Central to this innovation is a thinner, Cu(In,Ga)S2 chalcopyrite absorber coated with a robust metallic top layer, which potentially surpasses the performance of conventional front-illuminated designs. Using cobalt quaterpyridine molecular catalyst, photocurrent densities for CO2 reduction exceeding 10 mA/cm2 at 0.

Background: Irresponsible and wholesale use of antimicrobial agents is the principal cause of the emergence of strains of resistant microorganisms to traditional drugs. Oligoventin is a neutral peptide isolated from spider eggs of Phoneutria nigriventer, with antimicrobial activity against Gram-positive, Gram-negative, and yeast organisms. However, the molecular target and pathways of antimicrobial activity are still unknown.

This study aims to evaluate the effects of pandemic-related training suspensions on the functional performance of U-20 soccer players from a first-division club in Rio de Janeiro.
Methods: Forty-one male U-20 soccer players were assessed during the preseason (PS) periods of 2020 and 2021.
HIV-induced AIDS attacks the immune system, leading to opportunistic infections. This syndrome has been linked to an increased risk of developing uveitis and subsequent cataracts. Consequently, cataract surgery may be associated with intra- and postoperative complications in HIV/AIDS patients.
