In situ powder X-ray diffraction (PXRD) was used to monitor the crystal phase evolution and was quantified through Rietveld refinements, revealing the highest SrZnFe17O27 fraction at 1320 and 1340 °C. The microstructural development was examined using electron backscatter diffraction (EBSD) to elucidate changes in grain size and crystallographic orientation, revealing that SrZnFe17O27 grains underwent abnormal grain growth. Vibrating sample magnetometry measurements showed that the saturation magnetisation increased with increasing SrZnFe17O27 content, whereas the coercivity decreased due to the abnormal grain growth. Crystallographic texture analysis based on PXRD and EBSD data indicated a lower degree of grain alignment compared with similar methods used to prepare SnFe12O19.

The mica template regulates ZnO morphology and promotes multiple light scattering, while the TP layer simultaneously enhances UV absorption and scavenges reactive oxygen species.

Herein, we demonstrate the influence of morphology on the underlying charge storage mechanism of sulfur nanostructures, such as zero-dimensional (0D) sulfur quantum dots (SQDs) and 2D sulfur nanosheets (SNSs)-based electrodes for supercapacitors. The layered SNS electrode enhances the redox-active site accessibility and facilitates charge transport, resulting in higher capacitance than SQD, achieving best values of 30.32 and 40.15 mF cm⁻² in 1M KOH and H2SO4 electrolytes, respectively, at 5 mV s⁻¹. Further, the distribution of relaxation times (DRT) analysis revealed the improved ion diffusion and effective double layer formation at the interfaces of SNS account for its higher performance than the SQD. The champion symmetric supercapacitor (SSC), fabricated using high-performing SNS, exhibits high energy and power densities of 1.92 mWh cm-2 and 1605 mW cm-2 under 1M KOH and 2.12 mWh cm-2 and 1775 mW cm-2 under 1M H2SO4, surpassing many state-of-the-art supercapacitors. Notably, the excellent capacitance retention (110% in basic and 106% in acidic condition) with ~100% coulombic efficiency after 10000 GCD cycles for SNS-based device is ascribed to the effective electro-activation process and supported by post-cycling characterizations. This innovative 2D layered sulfur framework promise to be highly efficient electrode materials for future energy storage technology.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"88 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374913","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}

Using first principles calculations, we show that a relaxed quasi-one-dimensional vanadium oxychloride (VOCl) ribbon weakly favors ferromagnetism among the tested collinear states but remains energetically unfavorable relative to bulk VOCl. Encapsulation inside an armchair (11,11) carbon nanotube binds and preserves the ribbon while strengthening its ferromagnetic preference relative to the free ribbon. Comparative exchange mapping separates the effects of dimensional reduction, structural deformation, and the nanotube environment: deformation into the confined geometry alone stabilizes an alternating antiferromagnetic state, whereas restoring the nanotube reverses the sign of the transverse exchange interaction and strengthens the ferromagnetic diagonal exchange network. The FM preference persists for Ueff = 3-5 eV and in static magnetic calculations performed on the final snapshot of a 5 ps NVT ab initio molecular dynamics simulation at 300 K. Constrained finite-displacement calculations with the CNT host retained show no imaginary modes within the VOCl subspace. Electronic-structure and spin-density analyses identify V 3d states as the primary magnetic degrees of freedom, while the exchange comparison demonstrates that the weakly coupled nanotube host materially alters the magnetic hierarchy. Spin-orbit calculations place the easy magnetization direction along the tube axis. Under equivalent confinement, FeOCl remains strongly antiferromagnetic, confirming that the exchange response is chemistry dependent. These results demonstrate that nanotube confinement can selectively reorganize exchange interactions in metastable quasi-one-dimensional magnetic motifs.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"16 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368238","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}

Nevertheless, it remains elusive whether the field-induced Zeeman energy drives this unconventional ADMR through competition with exchange energy or magnetocrystalline anisotropy energy. Herein, we investigate the ADMR of the room-temperature vdW antiferromagnet (Fe0.56Co0.44)5GeTe2 with perpendicular magnetic anisotropy. The xy-plane ADMR exhibits a conventional cos2 dependence, in agreement with macrospin model predictions. In contrast, the ADMR in the xz-and yz-planes deviates cos2 dependence and the macrospin description. Remarkably, the xz-plane response is the exact sum of those obtained in the xy-and yz-planes, uncovering coupled contributions from anisotropic magnetoresistance and band structure modification. First-principles calculations reveal distinct Fermi-level density of states when rotating magnetization between out-of-plane and in-plane directions. Our findings demonstrate that the competition between Zeeman energy and magnetic anisotropy generates unconventional ADMR via anisotropic electronic structure modulation, offering a promising route for developing next-generation spintronic devices.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"21 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2026-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149368237","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}

Under mechanical stimulation, piezoelectric polarization induces dynamic charge modulation, significantly enhancing both piezo-catalytic degradation of carcinogenic pollutants (RhB) and electrocatalytic hydrogen evolution (HER) in alkaline medium. The optimized V2CTx-CoMoO4 composite exhibits an overpotential of 67 mV at a current density of 10 mA cm−2 with a Tafel slope of 92 mV dec−1 under ultrasonic vibration, indicating enhanced HER kinetics. In addition, the composite achieves a maximum degradation efficiency of 93.33% for RhB with a rate constant of 0.01103 min−1. The resulting piezoelectric-electrocatalytic synergy accelerates electron transfer kinetics and lowers the overpotential.
