Herein, 2,2′-biquinoline-4,4-dicarboxylic acid disodium salt (BCA) molecules with significant AIE characteristics were confined within the two-dimensional layers of Ni-MOF, forming a dye-embedded MOF (DE-Ni-MOF). A remarkable pressure-induced luminescence enhancement was observed when the confined BCA was released from high pressure to ambient conditions. In situ experimental and theoretical investigations under high pressure have revealed that the application of pressure compresses the lattice structure of DE-Ni-MOF, ultimately leading to the disruption of its layered framework. A binding interaction was established between the confined BCA molecules and the framework after pressure treatment, effectively restricting the vibrational and rotational motions of the BCA molecules. This binding was maintained to atmospheric pressure, and the pressure treatment significantly enhanced the luminescence of BCA.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1746–1753 1746–1753"},"PeriodicalIF":9.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903313","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}

The P/M composite incorporates Keggin-type phosphomolybdate into the porous MIL-101-Fe framework, enabling targeted degradation within the reductive TME and then releasing reduced PMo and Fe2+. The reduced PMo self-assembles into large clusters, leading to enhanced tumor retention, amplified PAI signals, and effective photothermal therapy (PTT). Concurrently, the liberated Fe2+ efficiently catalyzes H2O2 to generate hydroxyl radicals (•OH), contributing to CDT. Notably, the depletion of glutathione (GSH) by both MIL-101-Fe and PMo further augments the efficacy of CDT. As a result, this composite enables improved antitumor effects both in vitro and in vivo.

The origin of the relatively high ionic conductivity and ductility is poorly understood. Recently, these ionic glasses were found to have medium-range ordering (MRO) similar to that of metallic glasses. This MRO significantly impacts the properties of metallic glasses and is also expected to significantly impact the properties of ionic glasses. This work used ab initio molecular dynamics (AIMD) simulations to study the effect of ionic glass composition on the MRO. The AIMD models showed that the degree of MRO increased as the temperature of the LiSiPON ionic glass decreased. The modeling also showed that the MRO is suppressed when 50% of Li is substituted with Na. This work lays the foundation for using AIMD to identify clear structure–property relationships in ionic glasses, allowing their properties to be optimized.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1717–1722 1717–1722"},"PeriodicalIF":9.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903204","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}

The pollution of seas and oceans by microplastics highlights the urgent need to explore sustainable technologies for removing these pollutants from water. Nowadays, various studies are investigating methods to remove microplastics from water, but while these techniques are effective for larger microplastics, they often struggle to capture smaller particles. Recently, to address this challenge, superhydrophobic materials have been explored. These materials can efficiently remove microplastics from water due to their unique wetting properties, achieving removal efficiencies close to 100%. Various types of superhydrophobic materials, such as sponges, meshes, and particulate materials, have been used to remove microplastics under different conditions and environments. This review will highlight the most recent advances in superhydrophobic materials for effectively removing microplastics, as well as review key studies to better understand the microplastic removal mechanism and the intermolecular forces between these solid pollutants and superhydrophobic surfaces.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1723–1731 1723–1731"},"PeriodicalIF":9.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903201","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}

These heterostructures display remarkable stability in polar solvents, remaining almost unaffected by prolonged exposure to isopropanol and water, and exhibit high photocatalytic efficiency for the degradation of organic dyes (i.e., Rhodamine B and Methylene Blue) under visible-light irradiation, with good recyclability. Additionally, preliminary tests demonstrate CO2 reduction capabilities, which make these heterostructures promising for both the photocatalytic degradation of pollutants and photoelectrochemical CO2 conversion.

Herein we report a proof-of-concept strategy employing plastics–fertilizer homology toward this goal. Biomass-like supramolecular plastics were fabricated through solid-phase molecular self-assembly of alginate and alkylammonium surfactants, followed by calcium coordination. The resultant plastics display satisfactory dry and wet mechanical strength, comparable to that of conventional petroleum plastics, while being fully biodegradable. The biodegradation products were able to increase pak choi’s wet/dry weights by 40% and 12%, respectively, promoting both soil fertility and water retention. This natural closed-ring cycle is very similar to real biomass processes, verifying the plastics–fertilizer homology as a promising solution to white pollution and microplastics crises.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 5","pages":"1646–1653 1646–1653"},"PeriodicalIF":9.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143903228","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}
