The catalytic membrane reactors (CMR) were prepared using a commercial Hollow Fiber Membrane of corundum of 4 and 1400 nm and impregnated palladium. The tests performed were phenol hydrogenation, hydrogen peroxide generation ...

Hexavalent chromium Cr(VI) is toxic to living systems and must be removed fromwastewater. Chitosan is a cationic, biocompatible, biodegradable, biopolymer obtained from marine wastes. The performance of chitosan particles ...

Chitosan particles (CH) were obtained from seafood processing wastes (shrimp shells) and physicochemically characterized; deacetylation degree of CH was measured by Infrared Spectroscopy (FTIR) and potentiometric titration; ...

This investigation addresses the design of a series of poly(acrylonitrile-butadiene-styrene)/polyacrylonitrile–zinc oxide(ABS/PAN–ZnO) membranes by coaxial electrospinning. In the first instance, an optimization of ABS and ...

Surface properties play an important role in understanding and controlling nanocrystalline materials. The accumulation of dopants on the surface, caused by surface segregation, can therefore significantly affect nanomaterials ...

Organic-inorganic hybrids are considered an effective and environmentally compliant alternative to chromate-based anticorrosive coatings, currently banned due to the high toxicity of hexavalent chromium. In this work, ...

Soil aging and deterioration can be enhanced due to pollutant accumulation, which can impact food security in the near future. Considering the advances in soil decontamination strategies, nanomaterials have been successfully ...
