Unraveling Pathway Complexity in Photoreversible Supramolecular Hydrogels: Real‐Time Visualization and Sub‐Micrometric Photopatterning

Small, EarlyView.
This research demonstrates real‐time visualization of supramolecular sol‐gel transitions using Fluorescence Lifetime Imaging Microscopy (FLIM). By leveraging 5D visualization, integrating 3D space, time, and polarity resolution, we achieved maskless sub‐micrometric photopatterning within the gel matrix.

Beyond Removal Efficiency: Environmental Risk Assessment of Tartrazine Degradation via ZnO and TiO2 Nanoparticles in Mussels

Environmental Toxicology, EarlyView.
ABSTRACT Tartrazine (TZ) is a widely used synthetic azo dye with high aqueous stability, resulting in persistence in wastewater. Photoreactive nanomaterials, principally zinc oxide (ZnO) and titanium dioxide (TiO2) nanoparticles (NPs), are frequently employed for dye removal under light‐exposed conditions; nevertheless, their ecotoxicological ...

Effect of dye structure and redox mediators on anaerobic azo and anthraquinone dye reduction

Química Nova, 2012
We investigated the biological decolourisation of dyes with different molecular structures. The kinetic constant values (k1) achieved with azo dye Reactive Red 120 were 7.6 and 10.1 times higher in the presence of RM (redox mediators) AQDS and riboflavin,

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.
