TL;DR: The results of this study demonstrate for the first time the genotoxic and mutagenic effects of the dye CI Disperse Blue 291 in mammalian cells, thus stressing the need to develop non-mutagenic dyes and to invest in improving the treatment of effluents.

TL;DR: The structural evolution of CaTiO3 powders heat treated in conventional furnace and adapted domestic microwave oven was analyzed by X-ray diffraction (XRD), micro-Raman scattering (MRS) spectroscopy and ultraviolet-visible (UV-vis) absorption spectrography as discussed by the authors.

TL;DR: In this paper, the authors present a compiled and critical review of photoelectrocatalysis, trends and future prospects of the technique applied in environmental protection studies, hydrogen generation, and water disinfection, focusing on the applications of TiO2 and the production of nanometric morphologies with a great improvement in the photocatalyst properties useful for the degradation of organic pollutants, the reduction of inorganic contaminants, the conversion of CO2, microorganism inactivation and water splitting for hydrogen generation.
Abstract: The great versatility of semiconductor materials and the possibility of generation of electrons, holes, hydroxyl radicals, and/or superoxide radicals have increased the applicability of photoelectrocatalysis dramatically in the contemporary world. Photoelectrocatalysis takes advantage of the heterogeneous photocatalytic process by applying a biased potential on a photoelectrode in which the catalyst is supported. This configuration allows more effectiveness of the separation of photogenerated charges due to light irradiation with energy being higher compared to that of the band gap energy of the semiconductor, which thereby leads to an increase in the lifetime of the electron-hole pairs. This work presents a compiled and critical review of photoelectrocatalysis, trends and future prospects of the technique applied in environmental protection studies, hydrogen generation, and water disinfection. Special attention will be focused on the applications of TiO2 and the production of nanometric morphologies with a great improvement in the photocatalyst properties useful for the degradation of organic pollutants, the reduction of inorganic contaminants, the conversion of CO2, microorganism inactivation, and water splitting for hydrogen generation.

TL;DR: Among the tested cover crops, pearl millet and sunn hemp presented higher dry mass yield and nitrogen accumulation and release and Brachiaria grass had the highest decomposition rate and shortest half-life time.
Abstract: Dry mass production, decomposition rate and nitrogen (N) release were evaluated in a field experiment under seven cover crop types: pearl millet (Pennisetum americanum sin. typhoides), brachiaria grass (Brachiaria brizantha), sorghum (Sorghum bicolor L. Moench), pigeon pea (Cajanus cajan (L.) Mill sp), sunn hemp (Crotalaria juncea) and black oat (Avena strigosa Schreb), compared to a fallow and a traditional cropping system (control) in a cerrado soil (Uberaba-MG, Brazil). Among the tested cover crops, pearl millet and sunn hemp presented higher dry mass yield and nitrogen accumulation and release. Brachiaria grass had the highest decomposition rate and shortest half-life time. All crops reached the highest N liberation rate 42 days after desiccation.
