A comparative photocatalytic degradation study of cationic and anionic dyes using ZnIn2S4 photocatalyst

Semiconductor mediated photocatalysis has emerged as a promising solution for dye degradation and environmental remediation. Zinc Indium Sulfide (ZnIn2S4, ZIS) is a benign, eco-friendly, visible-light-responsive photocatalyst, exhibiting excellent opto…

Synthesis and evaluation of magnetite nanoparticles coated with (acrylamide-vinylpyrrolidone) polymers on the thermostability for application in harsh offshore reservoirs

Synthesis and evaluation of magnetite nanoparticles coated with (acrylamide-vinylpyrrolidone) polymers on the thermostability for application in harsh offshore reservoirs

To avoid the instability and degradation of downhole injection fluids, such as polymers and surfactants, for use in high-temperature (HT) offshore reservoirs, nanofluids with particles modified in different ways have been proposed as a capable thermore…

Steady-state and fluorescence lifetime quenching of self-assembled diphenylalanine/coumarin nanostructures as a method to determine dissolved O2 in water

Steady-state and fluorescence lifetime quenching of self-assembled diphenylalanine/coumarin nanostructures as a method to determine dissolved O2 in water

A fluorescent system formed by the combination of coumarin derivative and self-assembled peptide nanostructures was used as sensing system to determine dissolved oxygen (O2) in water samples. Detection was based on the sensing system fluorescence quenc…
