The fluctuation-induced conductivity survey reveals that the experimental data for both undoped samples and those doped with low concentrations (0.0–1.0 wt%) of the Al₂O₃–15 wt%ZrO₂ nanocomposite are well explained by the 3D Aslamazov-Larkin (AL) and 2D Maki-Thompson (MT) models, with 2D fluctuations being the most significant in all samples. The results indicate that samples with 0.1 and 0.2 wt% additives exhibit a wider region of 2D fluctuations than the undoped sample. This suggests that a minor addition of nanocomposite promotes the formation of phase-coherent fluctuating Cooper pairs. The value and temperature variation of the pseudogap Δ∗(T) for different composites were deduced using the local pairs model based on experimental fluctuation-induced conductivity data. It was observed that the transition temperature from the Bose-Einstein condensate (BEC) to Bardeen-Cooper-Schrieffer (BCS) regimes of local pairs, T_pair, rose from 117.5 K at the undoped sample to approximately 133.5 K at the composite containing 0.2 wt% additive. However, with higher additive concentrations, T_pair decreased, reaching 120.5 K at the composite containing 1.0 wt% additive. The estimated superconducting gap value at T = 0, Δ(0), rose from 250 K (21.5 meV) for the undoped sample to 254 K (21.9 meV) at the composite including 0.2 wt% additive, then dropped to 243 K (20.9 meV) at the composite including 1.0 wt% additive.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"329 ","pages":"Article 130053"},"PeriodicalIF":4.3,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, much research has been dedicated to replacing these biocides with environment-friendly alternatives. Particularly, the use of natural products that inhibit the settlement of fouling organisms is the key to antifouling coating technology. The purpose of this study was to develop antifouling paints by using eco-friendly compounds and implement a multifunctional coating factor. Natural-origin biocidal agents, such as capsaicin, and a copper-ion release system supported on synthetic zeolite ZSM-5 were used. The formulations resulted in viscosities and particle sizes similar to those of commercial antifouling paints. The capsaicin coatings exhibited less fracture damage and more resistance to deformation in the flexibility and cupping tests. In the adhesion tests, all formulations exceeded 3 MPa, thereby enhancing the adhesion values of conventional antifouling agents. However, the capsaicin coatings exhibited less abrasion resistance than those containing zeolite. Corrosion resistance tests using electrochemical impedance spectroscopy indicated good anti-corrosive properties, particularly in the coatings with 8 % and 10 % copper. All formulations proved to be bactericidal within 6 h, and some completely eliminated the cell density by 3 h, highlighting the effectiveness of the biocide against the marine strain <em>Pseudoalteromonas</em> sp.

In this process, the deposition conditions (laser fluence, gas pressure, target-substrate distance, deposition time, etc.) were optimized to enhance the SERS response. Different types of paper with different textures were tested, as it was also observed that the paper roughness significantly influences SERS efficiency.

Herein, this research focuses on an iron hematite (Fe₂O₃)-magnetite (Fe₃O₄) composite catalyst supported on SBA-15 using silica from cogon grass for phenol hydroxylation. The extracted silica exhibited a fine white powder appearance and an amorphous structure, used as a silica source for SBA-15 synthesis.

X-ray photoelectron spectroscopy (XPS) analysis provided insights into the surface of the catalyst, revealing that Fe₂O₃–Fe₃O₄/SBA-15 had the highest dispersion of iron species.
