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 ...

Unravelling the initiator‐only stage in alginate grafting: Radical‐induced depolymerization and its impact on acrylamide grafting efficiency

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Free‐radical grafting of natural polymers often assumes that initiators only create active sites before monomer addition. We tested this by exposing sodium alginate to potassium persulphate (KPS) under typical grafting conditions without monomer (acrylamide).

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 ...

Inhibition of ferroptosis by microbiota‐derived lithocholic acid underlies the intestinal radioprotection of a host defensin‐derived oligopeptide

iMeta, EarlyView.
AT9(C/G), an oligopeptide derived from human defensin 5, enriches Bifidobacterium pseudolongum and increases lithocholic acid (LCA) levels in the intestine. Reduced levels of LCA link to increased severity of ionizing radiation‐induced intestinal injury (IRIII) in both murine and clinical studies.

Stimuli‐responsive hydrogels: An intelligent tool for wound management

Interdisciplinary Medicine, EarlyView.
For chronic and complex wounds, this review focuses on intelligent hydrogels capable of responding to wound microenvironmental cues (e.g., pH, enzymes) or external stimuli (e.g., light, electricity). These advanced materials enable the dynamic regulation of drug release and real‐time monitoring of healing progression, thereby offering innovative ...

On the unlikelihood of specific long range forces in immunologic and enzymatic reactions [PDF]

, 1950
In the past few years, a great many experiments have been performed by Rothen (24, 25) which he has interpreted as suggesting that antigen and antibody, and enzyme and substrate proteins, can react specifically, although separated by distances of ...

Recent progress on stimuli‐responsive chitosan‐based biomaterials as drug carriers

Interdisciplinary Medicine, EarlyView.
This review discusses the recent progress in chitosan‐based drug delivery systems that respond to pH, redox, enzymes, reactive oxygen species, and combined stimuli. It examines design strategies, key mechanisms, and therapeutic applications, and also addresses current challenges while suggesting future approaches to enhance clinical translation and ...
