However, the antioxidant defense system in the tumor microenvironment, characterized by excessive glutathione (GSH) and thiol-containing proteins, often limits the effectiveness of photodynamic therapy. In this study, we report the development of a new multifunctional integrated nanozyme with thioredoxin reductase-oxidase (TrxRox) and GSH-oxidase (GSHox)-like activities. This nanozyme, termed Au^I-incorporated MOFs, was synthesized by embedding monovalent Au nanozymes into a light-sensitive metal-organic framework (MOFs) structure using an in-situ oxidation-reduction method. The intergrated Au^I nanozyme exhibited inhibitory effects on TrxR and presented significant anti-tumor properties. Moreover, the integrated nanozyme also demonstrates peroxidase-like activity, catalyzing the decomposition of hydrogen peroxide (H₂O₂) into hydroxyl radicals (•OH). Additionally, this nanomedicine effectively depletes existing GSH and TrxR, thereby enhancing the efficacy of photodynamic and photothermal therapy. Notably, under light conditions, this nanozyme induces oxidative stress within cells, leading to apoptosis and necrosis of tumor cells. Of note, it triggers immunogenic cell death and activating antigen-presenting cells to convert cold tumors into hot tumors. Therefore, Au^I-incorporated MOFs nanozyme demonstrates promising potential in photoimmunotherapy, offering new insights and strategies for tumor therapy.</p>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"683 Pt 1","pages":"552-563"},"PeriodicalIF":9.4,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the self-corrosion of the aluminum anode reduces anodic efficiency and battery capacity, limiting the broad commercial application of AABs. Herein, we propose the utilizing Allium Mongolicum Regel (AMR) extract as a green electrolyte additive to optimize the Al anode/electrolyte interface in alkaline AABs. Our findings indicate that the incorporation of AMR into NaOH electrolyte offers an effective strategy for preventing the self-corrosion of the Al anode, leading to significant enhancements in battery performance. Electrochemical experiments demonstrate that AMR achieves an inhibition efficiency of 53.9%. Through in-situ optical microscopy and in-situ attenuated total reflection Fourier-transform infrared spectroscopy, it is observed that the introduction of AMR can retard pitting corrosion by adsorbing onto the Al surface. This leads to a significant increase in specific capacity, from 1096 to 1667 mAh g^-1, compared with the electrolyte without AMR for AABs. Further analysis utilizing X-ray photoelectron spectroscopy, quantum chemical calculations, and ab-initio molecular dynamics determine that 4-hydroxycinnamamide (4-HCAA) and flavone molecules, which are the most active components of AMR, can bind with Al atoms through the carbonyl O functional group, forming an O-Al-O bond, thus suppressing the self-corrosion of the Al anode. The incorporation of the AMR extract into the electrolyte of AABs represents a sustainable approach for optimizing battery performance. This innovative strategy addresses a critical issue in the development of AABs, potentially creating new opportunities for their commercialization and widespread utilization as a reliable energy storage technology.</p>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"682 ","pages":"983-994"},"PeriodicalIF":9.4,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142805704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we unravel that CO₂R can occur before Cu₂O reduction (Cu₂O-R) when the applied potential is below -0.44 V and doping can improve its catalytic performance based on first-principles calculations. The pure Cu₂O(111) surface shows high activity and selectivity for the production of formic acid (HCOOH). However, the performance of CO₂R deteriorates on the reduced Cu₂O(111).

Importantly, Ga-Cu₂O exhibits the favorable bonding strength for *OCHO, which is responsible for the optimal catalytic activity (-0.18 V) among other p-block elements.

Therefore, enhancing the hydrophobic stability and mechanical durability of these coatings under such conditions is imperative. This study presents a novel approach where rigid Fe₃O₄ nanoparticles are encapsulated within porous diatomaceous earth (DME) and combined with high-adhesion acrylic resin (AR), resulting in a superhydrophobic photothermal coating that possesses both active and passive de-icing capabilities, fabricated through a straightforward one-step spraying technique. Nanosized Fe₃O₄ particles, modified for hydrophobicity and smaller than the critical nucleation radius, are densely packed within the DME micropores, forming a micro-nano structured coating with a contact angle of 160.1° and a rolling angle of 2.1°. This dense nanoparticle distribution facilitates preferential nucleation of ice crystal nuclei at the gas-liquid interface, rapidly leading to the formation of a robust and uniform ice shell, which effectively reduces the ice-solid contact area, resulting in loose ice droplets that initiate melting within 18 s. Additionally, the self-removal of condensed droplets from the surface enhances the water repellency and ice-phobic performance in low-temperature and high-humidity environments. The protection afforded by the DME microstructure and the releasable action of Fe₃O₄ nanoparticles allows the coating to maintain its superhydrophobic characteristics even after exposure to sandpaper abrasion, repeated de-icing, sand impact, and immersion in acid-base solutions.
