However, most known examples of 2D magnets have low environmental and thermal stability, posing a significant challenge to their eventual device integration. This work reports on the thermal stability of a recently discovered environmentally stable transition metal oxyhalide, CrOCl. Using differential scanning calorimetry, thermogravimetric analysis, and temperature-dependent X-ray diffraction, the studies show that van der Waals (vdW) layers of CrOCl exhibit remarkable thermal stability, significantly surpassing the temperature requirements for CMOS technology. CrOCl undergoes a two-step decomposition process, transforming into amorphous Cr2O3 at ≈620 °C by releasing chlorine from its surface. Additionally, thickness-dependent thermal stability studies show no significant decrease in decomposition temperature, dropping from 630 °C in the bulk material to 550 °C in few-layer samples and down to 500 °C in the monolayer. Further, comprehensive magnetization studies indicate that despite a reduction in overall magnetization, key magnetic properties such as saturation magnetization and spin-flip behavior are retained even after extreme thermal stress. These findings offer the first insights into the thermal stability of these transition metal oxychlorides as potential candidates for robust magnetic devices requiring 2D vdW magnets.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 14","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500278","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, V2CTx quickly degrades in water, which limits its performance and longevity. Furthermore, the relationship between V2CTx MXene synthesis parameters and their corresponding aqueous stability is underexplored. In this study, delaminated V2CTx MXene films synthesized with four tetraalkylammonium hydroxide intercalants were characterized for their structural and aqueous stability differences. Delaminated V2CTx MXene d-spacing, flake edge lengths, and surface morphology were generally dependent on the intercalant radius. Specifically, the intercalant radius exhibited a positive correlation with d-spacing and a negative correlation with flake edge lengths. These structural differences have direct impacts on the aqueous stability of V2CTx. For example, Raman spectra of each thin film indicated that amorphous carbon formation upon water exposure positively corresponded with flake edge lengths. 3D printed film holders were fashioned to mimic electrochemical cell configurations to evaluate vanadium dissolution from each film when exposed to water. Vanadium dissolution from each film was statistically similar (i.e., no correlation with intercalant radius) and substantial (i.e., ppm concentration range). These findings will benefit aqueous applications of V2CTx MXenes, where material degradation and vanadium release may impact MXene performance.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 14","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500145","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rigorous assessment of performance metrics encompasses electromagnetic shielding effectiveness, material thickness, electrical conductivity, mechanical properties, surface functionalization, durability, and application-specific performance characteristics. This work examines how MXenes (Ti3C2), with their exceptional conductivity and ease of textile application, can be coupled with other nanomaterials such as graphite, carbon nanotubes (CNT), polyaniline (PANI), and silver nanowires (AgNWs) to improve EMI shielding effectiveness. A comprehensive list of MXene-based hybrid nanomaterials offers materials scientists and engineers with an important reference framework for understanding and optimizing EMI shielding solutions. Finally, despite underlining MXene's enormous potential, this paper critically states existing constraints, such as nanomaterial dispersion, environmental stability, and production processes.

The role of subsequent H2O exposure in the hydrolysis of carbonyl and cyclopentadienyl ligands to complete the installation is also investigated. In situ FTIR study reveals that upon exposure of CpCo(CO)2 to MOF-808 at 115 °C, a long-lived, stable intermediate is formed that presents carbonyl stretching vibrations similar to the undissociated precursor that are attributed to multiple chemisorbed carbonyl complexes. In MOF-808, cobalt species are initially absorbed near the BTC linker rather than directly on the nodes, revealing the importance of non-covalent interactions in the installation process. DFT suggests that H2O exposure promotes carbonyl elimination but leaves a cyclopentadienyl-capped cobalt that is more stable than the complete hydrolysis product. The simulations are consistent with cobalt installation in MOF-808 using CpCo(CO)2 and H2O at 115 °C and further consistent with the lack of ALD thin film deposition of cobalt oxide thin films on planar supports.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 14","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500079","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particle ALD, one of the major challenges lies in the strong cohesive force causing nanoparticle agglomerates or aggregates, which requires their homogeneous dispersion. This review provides an overview on the developments and advancements of particle ALD, covering both reactor designs and applications. The fundamentals of ALD are first reviewed, followed by the reactor designs including fluidized bed reactors, rotating bed reactors, and atmospheric-pressure continuous spatial ALD reactors. Among them, the basics of particle fluidization are concisely outlined to establish a foundation for understanding fluidized bed reactors. The advantages and disadvantages of various reactor designs are compared and analyzed. Subsequently, the applications of ALD-modified nanoparticles are reviewed, with a focus on energy, catalysis, biomedicine, and cosmetics.

In vitro tests on Botrytis cinerea using the renowned PCN-222 and PCN-224 reveal modest photo-antifungal activities at the solid–gas interface when compared to their standalone tetrakis(4-carboxyphenyl)porphyrin (TCPP) linker. This in-depth study examines the direct detection of 1O2(g) phosphorescence at the solid–air interface, binding of the PMOFs with the spores of B. cinerea by fluorescence microscopy, fluorescence quenching of the PMOFs by oxygen, and rates of exciton migration evaluated through the singlet-singlet annihilation process. The conclusion is that a significant proportion of 1O2 is unable to escape the porous materials before deactivation, or does so too late to then be able to reach, and that excitation migration is not efficient enough to generate significant amounts of 1O2 directly at the MOF surface. Given that TCPP is its own interface with the gas phase, it is not hindered by these factors, which explains its higher efficiency under these circumstances.","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 14","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202500315","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This highlights the need for a standardized biomolecule immobilization process, enabling straightforward target detection on various surfaces. Cold atmospheric plasma technology offers a scalable solution, combining surface activation with molecule grafting in a single step. This technology is employed to construct stable surface-independent carboxylic acid (COOH) linker-layer coatings, enabling covalent protein immobilization via 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) chemistry and creating a robust biointerface for bioassay integration. The coating's composition, surface energy, thickness, topography, and stability confirm a secure COOH-rich layer. Biofunctionalization is studied in depth by immobilizing immunoglobulin G (IgG), streptavidin, and protein G. Enzyme-linked immunosorbent assay (ELISA)-based model bioassays demonstrate protein-independent functionalization and linker-layer stability of at least one month (stored in air). The calibration curve for IgG-biotin detection shows a high signal-to-noise ratio. Consistent performance across polymethylmethacrylate (PMMA), cyclic olefin copolymer (COC), polyvinyl chloride (PVC), and glass proves the method’s universal applicability.
