Multifunctional Manganese–Nucleotide Laccase-Mimicking Nanozyme for Degradation of Organic Pollutants and Visual Assay of Epinephrine via Smartphone

Analytical Chemistry, Journal Year: 2024, Volume and Issue: 96(11), P. 4736 - 4744

Published: March 11, 2024

As a natural green catalyst, laccase has extensive application in the fields of environmental monitoring and pollutant degradation. However, susceptibility to influences poor reusability seriously hinder its application. To address these concerns, for first time, manganese ion replaced copper as active center coordinate with guanosine monophosphate (GMP) synthesizing mimic high catalytic activity. Compared laccase, laccase-like nanozyme (Mn–GMPNS) demonstrated superior thermal stability, acid–base resistance, salt tolerance, reusability, substrate universality. Benefiting from activity Mn–GMPNS, epinephrine, significant neurotransmitter hormone associated numerous diseases, was visually detected within 10 min portable assay by smartphone. More encouragingly, Mn–GMPNS can efficiently degrade dye pollutants, achieving decolorization rate over 70% 30 min. Thus, coordination between nucleotide potential rational design nanozymes activity, low cost, good biocompatibility.

Crystal violet removal using ZIF-60: Batch adsorption studies, mechanistic & machine learning modeling

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 33, P. 103456 - 103456

Published: Dec. 4, 2023

This study, for the first time, reported utilization of ZIF-60 adsorptive removal organic pollutant from contaminated water. Characterization techniques were used to confirm synthesis adsorbent which was then study uptake crystal violet (CV) aqueous system. A remarkably high experimental (in excess 7000 mg/g) CV onto noted due careful selection process parameters while conducting batch adsorption studies. Response surface methodology technique utilized as tool response optimization and studying effect varying parameters. Temperature had most significant influence on followed by concentration, dose pH. Adsorption kinetics isotherm investigations conducted based optimized conditions, obtained good data fitting with more than one model suggests an intricate process. On other hand, thermodynamic studies revealed a highly endothermic spontaneous The post analysis π-π stacking interaction dominant force driving ZIF-60. Additionally, several machine learning models that distinct algorithms prediction An ensemble combination created using voting technique; this proved be accurate in predicting suggested its superior value evaluation metrics.

Decoration of a Glass Surface with AgNPs Using Thio-Derivates for Environmental Applications

Coatings, Journal Year: 2024, Volume and Issue: 14(1), P. 96 - 96

Published: Jan. 11, 2024

The aim of this study is to decorate a glass surface with silver nanoparticles (AgNPs) and further prove its efficiency in the removal some thio-derivatives—potential pollutants from water. Therefore, grafting glass-based platforms AgNPs will strongly influence their interaction other substances or molecules. most commonly used molecules for platform functionalization/modification are organosilanes. In case, main interest thioalkyl organosilanes because, after silanization, thio (-SH) functional groups that have high affinity can intermediate binding on surface. By decorating AgNPs, these surfaces become active adsorption dyes wastewater. Certainly, must bear -SH ensure surfaces. desired purpose was develop decorated able bind model molecules—dyes aqueous media (dithizone—DIT thioindigo—TIO), being potentially environmental applications.
