Decolorization of Orange-G Aqueous Solutions over C₆₀/MCM-41 Photocatalysts

Applied Sciences, 2019
The majority of the photocatalysts studied for azo-dye degradation are based on semiconductor materials. Studies reported on non-semiconducting materials are very scarce.

A simple method to screen for azo-dye-degrading bacteria [PDF]

, 2009
A stab-culture method was adapted to screen for azo dyes-decolorizing bacteria from soil and water samples. Decolorized azo dye in the lower portion of the solid media indicates the presence of anaerobic azo dyes-decolorizing bacteria, while aerobic ...

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Channel Microenvironment‐Controlled Pillared MOF as Efficient Triboelectric Nanogenerator Material for Self‐Powered Degradation of Organic Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The pore microenvironment regulation of metal–organic framework (MOF) significantly enhanced the output performance of triboelectric nanogenerators (TENG) through SC‐SC transformation, which provides a new idea for the construction of self‐powered degradation systems for organic pollutants.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...
