The different heating stages of the methods produce distinct morphologies, doping concentrations, and some other characteristics. CCZ-HT consists of nanoellipsoids, while CCZ-MA consists of nanoflakes. The doping concentrations of cerium and carbon in CCZ-MA are higher than those in CCZ-HT. The types of crystal defects in the doped materials are different, leading to differences in their absorption and emission properties. The band gap energy of CCZ-MA is 2.85 eV, which is lower than that of CCZ-HT (2.92 eV). While CCZ-HT does not exhibit near-infrared emissions, CCZ-MA exhibits relatively strong emissions. CCZ-HT and CCZ-MA had a degradation capacity for ofloxacin (Ofx) under visible light that was 2.63 and 3.38 times superior to that of pure ZnO, respectively. The addition of Ce and C improved the band structure by slightly moving the conduction band and reducing the band gap, which allowed for better light absorption in the visible range and helped separate charge carriers. These enhancements immediately facilitated enhanced photocatalytic efficacy in the breakdown of ofloxacin. The CCZ-MA material exhibited superior photocatalytic activity due to its advantageous shape, increased surface area, and enhanced charge trapping capability associated with flaws. The functions of photo oxidized fragments and reaction intermediates were also examined. This study postulated a photodegradation mechanism for Ofx.</p>","PeriodicalId":102,"journal":{"name":"RSC Advances","volume":" 32","pages":" 26552-26566"},"PeriodicalIF":3.9,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/ra/d5ra03520a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144695680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate the association between consumption of 4 types of meat (processed meat, unprocessed red meat, poultry, and fish) and the risk of incident AP. <i>Materials and methods</i>: We included 489 708 participants from the UK Biobank between 2006 and 2010. A food frequency questionnaire (FFQ) was used to document the frequency of four types of meat. Data from validated 24-hour dietary recalls were used to quantify the meat intake and reduce measurement errors. The outcomes of our study were incident AP among participants. Hazard ratios (HRs) with 95% confidence intervals (CIs) for the associations between meat consumption and incident AP were calculated using Cox proportional hazard models. <i>Results</i>: Over a mean (standard deviation) follow-up of 13.2 (2.1) years, 3079 incident AP cases were recorded. We observed that higher consumption of processed meat was associated with a higher risk of incident AP (per 25 g per d: HR: 1.29, 95% CI: 1.12-1.47). In contrast, higher consumption of fish intake was associated with a lower risk of AP (per 25 g per d: HR: 0.78, 95% CI: 0.68-0.89).

Nanoparticles (NPs) have emerged as powerful tools in modern medicine, but their clinical translation has been hindered by issues such as rapid immune clearance, limited targeting, and off-target toxicity. Recent advances in cell membrane-coated nanoparticles (CM-NPs) provide an innovative solution by combining synthetic nanocarriers with natural cell membrane functionalities. By coating nanoparticles with membranes derived from red blood cells, cancer cells, immune cells, or platelets, CM-NPs inherit properties such as immune evasion, prolonged circulation, biocompatibility, and homotypic targeting. In drug delivery, CM-NPs enhance drug targeting and minimize off-target effects, especially in cancer therapy, where they selectively deliver chemotherapeutics to tumor cells. In phototherapy, these NPs enable precise tumor targeting for photothermal and photodynamic therapies, reducing damage to healthy tissues. In immunotherapy, immune cell-derived NPs modulate immune responses and improve cancer treatment efficacy by delivering immune modulators directly to the tumor microenvironment. Overall, CM-NPs provide a versatile platform to enhance the specificity, safety, and efficacy of drug delivery, phototherapy, and immunotherapy, with substantial potential for clinical translation and disease treatment. This review provides a comprehensive overview of CM-NP preparation methods, highlights their versatile biomedical applications, and critically discusses the remaining challenges and future directions.

Through a combination of experiments and numerical simulations, we demonstrate that fluid flow, dictated by the channel geometry alone, governs the dynamics, shape, and size of these domains. We find that channel constrictions extend the lifetime of dowser domains by accelerating their growth, while channel expansions slow down their dynamics and shorten their lifetime. In addition, manipulating the flow paths of dowser domains through serpentine microchannels can further influence their shape and lifespan. We also demonstrate domain splitting in a T-junction microchannel.
