Zeolitic minerals usually contain only one dominant zeolite type. The use of minerals with mixtures of zeolites in similar proportions can affect the interaction of chemical species with the zeolitic matrix, altering the behaviour of the resulting materials. In this work, a mineral consisting mainly of a mixture of two zeolites, mordenite (MOR) and clinoptilolite-heulandite (HEU) with equivalent fractions, was used to develop materials carrying nutrients (N, P, and K) for agricultural crops. The mineral matrix provides important elements such as K and Si, while N and P were incorporated into the material by treatment with ammonium hydrogenphosphate and urea. The presence of superficially adsorbed PO₄ ^3-, NH₄ ⁺ exchanged in zeolites, and urea arranged on the surface so that it covers the material and interacts with the zeolitic frameworks, was evidenced by Fourier-transform IR spectroscopy, adsorption measurements, scanning electron microscopy, scanning transmission electron microscopy, and other methods, as well as through culture tests. The complexity of the multiphase zeolitic support leads to changes in the position and intensity of FTIR bands compared to other similar materials developed using simpler zeolitic carriers dominated by HEU zeolite. The most intense NH₄ ⁺ band was observed at 1402 cm^-1, while for a HEU zeolite it was at 1540 cm^-1. This difference was associated with a higher NH₄ ⁺ content in MOR compared to HEU. Accordingly, the shift experienced by the urea amino group bands when it interacts with the frameworks of these zeolites is different. The applied treatments did not affect the structures (as evidenced by XRD) and other qualities of these zeolites, highlighting their ion-exchange and adsorption properties for nutrient release and reversible water retention. This is essential for the use of this material as a slow-release fertilizer that efficiently provides nutrients for the agroecological development of plants, as evidenced in the cultivation tests.</p>","PeriodicalId":8802,"journal":{"name":"Beilstein Journal of Nanotechnology","volume":"17 ","pages":"381-395"},"PeriodicalIF":3.5,"publicationDate":"2026-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12951318/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147347145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 this study, we developed nanostructured PDA and PTYR layers on stainless steel 316L via a novel in situ oxidation process and evaluated their physicochemical properties and cellular interactions at the nano/microscale. Surface characterization revealed that the polymeric coatings formed a homogenous layer with distinct topographical features and thickness in the nanometer range for PTYR and in the micrometer range in case of PDA. Compared to PDA, PTYR coatings exhibited a nanoparticulate surface morphology and higher stability under physiological conditions. Wettability, roughness, and amine group density were systematically analyzed to determine their influence on interactions with fibroblasts and platelets. Our results show that PTYR nanocoatings significantly reduced platelet adhesion and activation, whereas PDA coatings, due to their higher primary amine content, could in some cases enhance platelet adhesion. Furthermore, fibroblast attachment was primarily influenced by coating roughness, with a specific threshold beyond which adhesion did not increase or was negatively impacted.

Different from the CNT film, CNSs are a self-standing material that can operate in the absence of a supporting substrate, showing high flexibility, light weight, and mechanical robustness. We tested our synthesized CNSs as active material for the production of antennas working in the radio frequency (RF) range to determine whether CNT sponges present, in addition to practical advantages over CNT films, also an actual performance gain. The antenna built from CNSs shows an enhanced response gain compared with that of the MWCNT film, with both antennas having a maximum positioned around 4.8 GHz. After identifying the best CNT-based sample, the experiment focused on improving the CNS antenna's response. In particular, we observed that the response of <i>S</i> ₁₁ = -22.6 dB around 4.8 GHz from the CNS antenna improved after a mild treatment with ethanol, reaching S₁₁ = -32.6 dB measured after 10 min of waiting. This observed effect is studied in detail with scanning electron microscopy and Raman spectroscopy, which point to significant modifications of the CNS's inner morphology after the treatment. Signal reception tests simulating real-world operation conditions were also carried out at two different distances to evaluate the practical application of the CNS as RF antennas.
