Al0 RHEA exhibits severe oxidation at 1000 ℃, characterized by significant weight gain and the formation of porous, cracked oxide layers due to the volatilization of MoO3 and V2O5 and the growth of needle-like oxides. In contrast, the addition of Al improves oxidation resistance in Al5 RHEA, which forms a continuous, dense, and adherent oxide layer. First-principles calculations indicate that Ti has the highest oxygen affinity and dominates initial oxygen adsorption, but the resulting TiO2 is loosely packed and insufficient for protection. The composite oxide AlNbO4 exhibits unique “integrator and stabilizer” functions. The addition of Al promotes the formation of composite oxide AlNbO4, which combines loose TiO2 particles and improves the overall stability and integrity of the oxide layer. Furthermore, the formation of AlNbO4 contributes to a more balanced Pilling–Bedworth ratio (PBR), which helps alleviate internal stress accumulation during oxidation and enhances the adhesion and mechanical stability of the oxide layer.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"53 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007268","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}

Currently, ISE is mainly employed for the detection of various ions and small molecules. Its application in detecting biomacromolecules is still not mature. Glycoproteins have been pivotal biomarkers for a range of biological conditions and they are abundant in circulating systems, rendering them suitable targets for bioassay. Herein, a label-free lectin-functionalized polymeric membrane ISE was fabricated for assay of invertase (INV) as a model glycoprotein. This strategy relied on the surface blocking principle to induce ion flux change of tetrabutylammonium chloride marker ion under zero-current condition. This ion flux change translated into the observable potentiometric responses. INV is heavily mannosylated, so concanavalin A has been utilized as the recognition element to capture INV. The fabricated polymeric membrane ISE was successfully exploited for the quantification of INV within the range of 10-13 to 10-8 M, yielding a limit of detection as low as 1.6 × 10-14 M. Good selectivity, reproducibility, repeatability and stability was achieved for the fabricated ISE. Excellent recoveries were obtained in spiking experiments, demonstrating that the lectin-functionalized polymeric membrane ISE was capable in glycoprotein assay within complex matrices. This study further extended the scope of analytes with polymeric membrane ISE from common ions and small molecules to biomacromolecules.","PeriodicalId":305,"journal":{"name":"Electrochimica Acta","volume":"27 1","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007183","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}

The AlV3 remains unchangeable during the hydrogen absorption/release cycles. Remarkably, the MgH2-10 wt% AlV3 composite exhibited the best performance, and it can absorb 4.9 wt% hydrogen in 15 min at 523 K, and reach a hydrogen desorption value of 6 wt% within 1500 s at 623 K. Hydrogen absorption and desorption activation energies were dramatically lowered to 78.2 and 54.69 kJ/mol, respectively. Notably, the composite maintained high hydrogen release and absorption retention rates of 98% and 95% after 50 cycles.

However, achieving controllable p/n-type doping and high-quality growth remains a challenge for most emerging metal oxide semiconductors. In this study, we demonstrate the creation of in-plane ferroelectric p/n homojunction superstructures in BiFeO3 (BFO) films, enabling bias-free photoelectrochemical (PEC) reactions. By leveraging in situ oxygen vacancy (VO) engineering, we enabled reversible switching between p- and n-type conductivity in BFO, thereby constructing p/n superstructures with densely packed depletion regions. Consequently, the superstructure achieves a dramatic improvement in carrier collection efficiency, as evidenced by an increased H2O2 production (8.6 times higher than that of p-BFO and 16.7 times higher than that of n-BFO). Furthermore, selective catalyst deposition on the p- and n-regions facilitates bias-free water splitting. The approach is readily adaptable to other ferroelectric materials, where VO-mediated conductivity modulation is feasible.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"16 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the poor chemical affinity between fluorinated porous precursors and gold substrates causes the agglomeration of nanostructures, resulting in uneven nanoporous morphology and accelerating lubricant leakage. Simultaneously, the weak interfacial adhesion between the nanostructures and the substrate may lead to the detachment of nanostructures under blood circulation. Herein, fluorinated gold nanoporous structures exhibiting uniform morphology were tethered on gold coatings via metallic bonding. The vertically aligned dendritic gold frameworks were prepared via in situ chloroauric acid disproportionation, which avoided agglomeration and served as the nanoporous structure. Fluorinated alkyl chains were covalently grafted onto the nanostructures with no considerable influence on morphology. The nanostructures showed no severe damage after 20 min of ultrasonication and 14 days of saline immersion. No significant lubricant leakage was detected after 24 h of in vitro blood circulation. The SLIPS significantly resisted the adhesion of thrombocytes and plasma proteins and suppressed biofilm formation.

However, the performance of blue perovskite QDs lags far behind that of their red and green counterparts, especially those with color coordinates approaching (0.131, 0.046), which meet the Rec. 2020 specification for blue emitters. This article employs a hot injection method to epitaxially grow CsPbBr3 nanocrystals (NCs) on the surface of Pb-doped Ni–Co LDH. The doping of Pb in the LDH provides epitaxial anchoring sites for the growth of the perovskite nanocrystals. The resulting CsPbBr3@Pb-LDH composite exhibits stable blue emission characteristics. The photoluminescence quantum yield (PLQY) increased from 37.65% for CsPbBr3 to 74.26%, accompanied by an extended fluorescence lifetime (6.42 ns). It retained 48% of its initial photoluminescence (PL) intensity after continuous irradiation for 5 h. We utilized these NCs as a color conversion layer to develop efficient white light-emitting diodes (WLEDs). The resulting pure white emission exhibited color coordinates of (0.312, 0.327).
