Abstract The Fenton‐like process, utilizing zero‐valent iron (Fe 0 ) and hydrogen peroxide (H 2 O ), is employed to degrade refractory organic matter in membrane bioreactor (MBR) effluent derived from landfill leachate. However, the rate‐limiting Fe 2+ /Fe 3+ redox step diminishes treatment efficacy generates substantial sludge. This study elucidates mechanism by which ultraviolet (UV) irradiation augments /H process for removal of MBR effluent. results show that UV‐ enhanced H effectively disrupts aromatic structure compounds, reducing molecular weight, degree polymerization, humification. Compared with efficiency UV 254 , color number, total carbon treated UV/Fe increased 24.16%, 14.62%, 57.46%, respectively. Concurrently, generation sludge was reduced 21.6%. enhancement primarily attributed UV's ability intensify cycle expedite surface corrosion yielding more oxides. accelerates decomposition generating a higher quantity • OH through both homogeneous heterogeneous reactions. removed oxidation OH, as well adsorption precipitation facilitated iron‐based colloids.

FeAu Bimetallic Nanoparticle as Fe(0) Reservoir for Near Infrared Laser Enhanced Ferroptosis/Pyroptosis‐Based Tumor Immunotherapy

Advanced Functional Materials, Год журнала: 2024, Номер 34(49)

Опубликована: Июль 21, 2024

Abstract Iron (Fe)‐based nanoparticles (NPs) have attracted considerable attention in nanomedicine research due to their enhancement effects magnetic resonance imaging (MRI) and cancer therapy. Although zero‐valent Fe (Fe(0)) can serve as an active catalyst decompose H 2 O into reactive oxygen species (ROS), its activity is compromised physiological conditions susceptibility oxidation. Here it reported that a 9 nm FeAu alloy NP system efficiently stabilize Fe(0) neutral pH solution, but release tumor‐bearing environment, catalyzing decomposition ROS. 3 4 NPs Au are well‐known for biocompatible, effectively eliminate cells at IC 50 low 15 µg mL −1 Fe. Further proteomics analysis reveals concomitantly induce both ferroptosis pyroptosis. Additional near‐infrared (NIR) irradiation further increases cell death promotes maturation of dendritic within tumor‐draining lymph nodes infiltration helper T cytotoxic lymphocytes tumor sites, resulting significant reduction growth metastasis. The studies demonstrate great potential stable reservoir pH/NIR controlled pyroptosis co‐mediated immunotherapy.
