Enhanced degradation of ciprofloxacin in water using ternary photocatalysts TiO/SnO/g-CN under UV, visible, and solar light.

In this study, we report on the synthesis of ternary photocatalysts comprising TiO/SnO/g-CN for the degradation of ciprofloxacin (CIP) in water. SnO nanoparticles were synthesized via the sol-gel method, while g-CN was obtained through melamine calcination. Commercial TiO and SnO nanopowders were also used.

Reducing toxic element leaching in mine tailings with natural zeolite clinoptilolite.

The use of natural zeolite clinoptilolite to reduce the leaching rate of potentially toxic elements such as Cd, Pb, and Mn in soil from mine tailings was studied. Soil from the surroundings of the mine El Bote in Zacatecas, Mexico, was analyzed, and the zeolite was characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, and nitrogen physisorption. An ammonium-exchange method for the zeolite was employed.

Drifting away. Seawater survival and stochastic transport of the invasive Carpobrotus edulis.

Coastal areas are vulnerable and fluctuating habitats that include highly valuable spaces for habitat and species conservation and, at the same time, they are among the most invaded ecosystems worldwide. Occupying large areas within Mediterranean-climate coastlines, the "ecosystem engineer" Carpobrotus edulis appears as a menace for coastal biodiversity and ecosystem services. By combining the observation, current distribution, glasshouse experiment, and dispersion modeling, we aim to achieve a better understanding of the successful invasion process and potential dispersion patterns of C.

Anaerobic digestion of bean straw applying a fungal pre-treatment and using cow manure as co-substrate.

The significant amounts of agriculture residues such as bean straw (BS) in rural areas, advises its valorisation for energy recovery. The feasibility of using BS for biogas production through anaerobic digestion was assessed. Prior to this, a fungal pre-treatment to hydrolyse BS with s was studied at 30°C and 100 rpm in orbital incubators with 1, 10 and 30 mg fungus/g straw for 14, 21 and 28 days.
