Removal of Chlortetracycline Chlorhydrate by Photo-Fenton Process: Experimental Study and ANN Modelling

Kemija u industriji : Časopis kemičara i kemijskih inženjera Hrvatske, 2023
The present work aimed to study the feasibility of photo-Fenton oxidation for the degradation of chlortetracycline chlorhydrate (CTC) in aqueous solutions, as well as the modelling of system behaviour by artificial neural networks. The removal performance of CTC oxidation by the Photo-Fenton process was studied under solar radiation.

Sodium Ascorbate‐Accelerated Gelling Hydrogels With Rapid Self‐Mineralized Capacity for Chronic Wounds

Advanced Science, EarlyView.
An immunoregulatory hydrogel based on sodium ascorbate (SA)‐accelerated gelation and in situ self‐mineralization is prepared here. Such a hydrogel is constructed by mixing benzaldehyde‐ and cyanoacetate‐functionalized dextran with silver nitrate (AgNO3) and SA, enabling the ultrafast solidification and in situ self‐mineralization of silver ...

A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

Advanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...

An Edible Biohybrid Platform Accomplishes In Situ Fenton‐Mediated Enteral Nanoplastics Aging and Excretion

Advanced Science, EarlyView.
An edible biohybrid platform triggers nanoplastics (NPs) aging and agglomeration by in situ generating hydroxyl radicals within the intestine. The enlarged NPs are unable to penetrate the intestine and are subsequently excreted. Simultaneously, probiotic biofilms reinforce the intestinal barrier.

Interfacial Proton‐Relay Microenvironment Enables Self‐Driven Singlet Oxygen Generation under Neutral Conditions

Advanced Science, EarlyView.
An interfacial proton‐relay microenvironment at MoS2‐CuCl heterostructures enables selective O2 activation to 1O2 under neutral conditions. Electron‐deficient sulfur sites mediate proton transfer to Cu‐bound O2, accelerating *OOH hydrogenation while suppressing O─O bond cleavage, achieving stable, efficient pollutant removal.

Intrinsically Mitochondria‐Targeting Nanozyme via Coordination‐Assembly of Natural Quercetin for Cascade Antioxidant Therapy of Cerebral Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...
