The EU’s political agenda has included among its priorities the issue of sustainable mobility, with the aim of curbing CO2 emissions and reducing air pollution. This objective implies the introduction into the EU car market of low-polluting cars, such as cars powered by an electric battery (BEV). The current research...

The expansion of pervious areas is an essential and common concept in mitigating non-point pollution runoff in urban areas. In this review, literature related to the expansion of pervious areas is introduced. In addition, the potential application of porous concrete as a medium for constructing the bottom and side walls...

This study investigated the use of NiSe2/Ag3PO4 nanocomposite catalysts for the photocatalytic degradation of RhB and BPA pollutants. Samples of pure NiSe2, Ag3PO4, and NiSe2/Ag3PO4 composites with varying NiSe2 (10%, 20%, and 30%) proportions were synthesized using hydrothermal techniques. The 20% NiSe2/Ag3PO4 composite showed the greatest photocatalytic efficiency for both...
