The BCE platform features a three-dimensional cell-based structure fabricated with projection microstereolithography (PμSL) and enhanced with the gold-based photothermal conversion coating. This structure and photothermal conversion coating synergy optimizes water transport, light absorption, and thermal management, resulting in an ultrahigh evaporation flux. The BCE mimics the mechanisms that enhance performance in the tree, where each cell operates both independently and synergistically. Furthermore, the evaporator maintains exceptional structural integrity and stable operation in extreme environments, including natural seawater, acidic and alkaline solutions, and industrial wastewater. These findings position the BCE as a robust and scalable platform for sustainable water desalination and wastewater treatment technologies, contributing significantly to global water security.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"92 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144693452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a systematic chemical bath deposition (CBD) approach for fabricating ZIF-8 films with precisely controlled thicknesses of up to 2.5 μm on functionalized surfaces. Film particle evolution and growth mechanisms were investigated by using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and time-of-flight secondary ion mass spectrometry (ToF-SIMS) combined with in situ growth monitoring. Imidazolate achieved a uniform growth rate of 95 nm per cycle, and imidazolate-surface interfacial coordination was elucidated. By integrating these controllable ZIF-8 films with a quartz crystal microbalance (QCM), we developed a gravimetric gas sensor that demonstrated enhanced CO2 adsorption capacity with increasing film thickness and achieved a detection limit of 0.5%. This systematic approach to controlling the ZIF-8 film thickness enables precise quantification of gas absorption, advancing the development of high-precision gas sensors for environmental monitoring applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"15 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing thermoresponsive biobased hydrogel sensors face challenges in rapidly responding to ambient temperature changes and retaining flexibility at subzero temperatures. To overcome these limitations, a novel hydrogel composed of dextrin, glycerol, and the ionic liquid monomer tetrabutylphosphonium styrenesulfonate (PSS) was developed and utilized as a smart sensor material for the first time. The thermoresponsive characteristics of PSS endow the hydrogel with remarkable thermoresponsiveness, which is a lower critical solution temperature (LCST)-type phase transition. In addition, the hydrogel can be used as a thermally responsive material over a broad temperature range of 20-60 °C. We used glycerol and glycidyl methacrylate dextrin (Dex-GMA) monomers with a multihydrogen bond structure to construct a Dex-GMA-PSS conductive hydrogel with antifreeze properties even at -20 °C.

It has been demonstrated that sporopollenin microcapsules derived from a variety of pollen species could function as efficient drug carriers due to their great thermal stability, resilience to harsh chemicals, homogeneity in size, and biocompatibility. Herein, we engineered a biohybrid nanozyme-based edible sporopollenin system, which can be applied to effectively treat IBD. The biohybrid sporopollenin (CeNP-P) loaded with a cerium oxide nanozyme (CeNP) was encapsulated in microspheres (CeNP-P/MS) by a microfluidic electrospray technique. This micronanosystem protects the CeNP-P from degradation in gastric conditions and enables the rapid release of CeNP-P in the intestine. The released CeNP exhibited the desired anti-inflammatory effects by suppressing pro-inflammatory cytokines and scavenging reactive oxygen species. To explore its practical value, in vivo experiments have been carried out with an IBD mouse model. Compared to the IBD group, the treatment groups displayed significant therapeutic outcomes, particularly the CeNP-P/MS group. Following taking CeNP-P/MS orally, key IBD symptoms were greatly alleviated, as evidenced by the restored colonic morphology, enhanced intestinal barrier integrity, and induced inflammatory responses. Collectively, these findings demonstrate that the present edible system can offer a promising strategy for the effective treatment of intestinal diseases.</p>","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":" ","pages":"41747-41755"},"PeriodicalIF":8.3,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
