In this work, the dust mitigation properties of nanostructured substrates with thin insulating and conductive coatings are investigated. To examine the contribution of capillary, electrostatic, and van der Waals forces to the surface's overall dust adhesion, the relative humidity is varied to control their relative contributions. Experiments show that samples with conductive coatings can have up to 91.0% less coverage than insulating sample under low humidity. The results indicate that the electrical properties of surface coatings play a significant role in mitigating dust adhesion forces at low humidities, where electrostatic forces dominate. In addition, reduced surface energy and nanostructured features are key for an improved anti-dust performance at all humidities. The results demonstrate that the nanostructure with conductive coatings is highly anti-dust and has less than 2.5% percentage area coverage throughout the humidity range. This research improves understanding of the interparticle forces between substrate and particulate and explores viable alterations of surface geometry and chemistry for passive dust mitigation that are applicable across a broad humidity range.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147691089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of different preparation methods and doping concentrations on the crystalline structure, particle size, and photocatalytic performance of TiO2were investigated. It was found that TiO2prepared through supercritical hydrothermal synthesis exhibited higher crystallinity and smaller particle size. After doping with hydroxylated MWCNT, the composite material demonstrated excellent photocatalytic performance for the degradation of methylene blue. The optimal photocatalytic activity was achieved at a doping concentration of 4 wt%, with a degradation rate reaching 69.8%. The enhanced performance is attributed to the formation of Ti2013C and Ti-O-C bonds between MWCNT and TiO2, promoting charge transfer, suppressing electron-hole recombination, and broadening the material's optical absorption range. Further studies revealed that the composite material prepared by the one-step hydrothermal method exhibited lower crystallinity and weaker photocatalytic activity, with TiO2particles tending to coat the surface of MWCNT, thereby limiting its photocatalytic effectiveness. These findings provide significant theoretical guidance for developing highly efficient photocatalytic materials.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147674890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work presents skyrmion-based majority gate and minority gate architectures implemented on a ferromagnet-heavy metal (FM-HM) bilayer structure. These skyrmions move along ion-defined tracks. The energy-efficient and compact logic gates are implemented by utilizing the skyrmion-skyrmion repulsion property, ion-defined tracks and their edge confinement effects. The proposed designs are validated through micromagnetic simulations, which show their ability to execute the basic logic functions such as NOT, AND, OR, NAND, and NOR without additional physical modifications or voltage-to-skyrmion conversion circuitry. Systematic variations in the track inclination angle (ϕ) and lateral track spacing (YLat) indicate that successful gate operation is restricted to angles below 10°, beyond which skyrmion trajectories deviate. YLat should not be excessively wide; otherwise, skyrmions will be insufficiently close to each other to exert a repulsion force, thus hindering their ability to cross the barriers. The temperature fluctuation study shows the susceptibility of these devices up to Tnoise = 60 K for increased barrier widths, anisotropy gradient, and applied current. Furthermore, a cascadable full adder is designed using the proposed majority and minority gates, demonstrating the potential for scalable and low-power beyond-CMOS nonvolatile logic-in-memory (NV-LIM) architectures. The proposed skyrmion-based majority and minority gates are structurally simpler, cascadable, and fully conservative.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147776780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The WF is a key parameter for charge injection, transport, and device performance. By adjusting molecular design, dipole orientation, and surface coverage, SAMs allow precise tuning the WF, optimizing energy-level alignment in devices such as organic solar cells (OSCs), organic light-emitting diodes (OLEDs), and organic thin-film transistors (OTFTs). This review focuses on WF modulation of gold electrodes, a widely used material due to its chemical stability, high conductivity, and compatibility with thiol-based SAMs. We provide a comprehensive overview of thiol derived SAMs for gold surface modification, emphasizing their impact on WF as measured by Kelvin Probe Force Microscopy (KPFM), Kelvin Probe (KP), and Ultraviolet Photoelectron Spectroscopy (UPS). Key parameters including molecular dipole, packing density, chain length, and terminal groups are discussed, along with the advantages of mixed SAMs for achieving precise WF control. These studies demonstrate that strategic molecular selection enables WF tuning across a broad range of 3.7 to 6.0 eV on gold surfaces.

Bio-piezoelectric materials like γ-glycine offer unique advantages due to their biocompatibility and piezoelectricity. However, their practical application is limited by the challenge of achieving macroscopic dipole alignment. Herein, we propose an innovative electric field-assisted physical vapor deposition (PVD) strategy to address this issue. By applying a continuous DC bias field during PVD crystallization, macroscopically polarized γ-glycine arrays with uniform molecular orientation have been successfully fabricated. Systematic characterizations using XRD, SEM, and PFM confirm enhanced crystallinity, γ-phase purity, and uniform polarization orientation. Piezoelectric energy harvesters based on these arrays exhibit a maximum open-circuit voltage of 0.25 V under 40 N periodic compression-over 400% higher than devices prepared without the electric field. Density functional theory calculations further reveal that directional hydrogen bonding in the non-centrosymmetric P31 crystal structure enhances dielectric polarization and piezoelectric response. This work is devoted to providing a scalable route to high-performance biocompatible energy harvesters and offering new insights into controlling polar orientation in molecular crystalline materials.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147777029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limitations such as layer stacking and the poor intrinsic catalytic activity of its basal plane often overshadow these advantages, restricting its broader application in advanced technologies. To overcome these challenges, curved graphene (CG) has emerged as a material with enhanced properties, offering a solution to the inherent limitations of planar graphene. Curved graphene exhibits superior performance in these applications due to its unique features, such as a large surface area, which facilitates rapid charge and discharge cycles, prevents catalyst aggregation, promotes efficient electron transfer, and exposes abundant active sites for catalytic reactions. These advantages collectively enhance the functionality, efficiency, and durability of CG in electrochemical energy systems.

However, the size of the dispersed TiO2nanoparticles affects the transparency of their hybrid materials, while their crystallinity influences the RI. Simultaneously optimizing both properties presents a significant challenge. In this work, we employ an acetic acid-mediated solvothermal method to synthesize TiO2nanoparticles. We show that this method uniquely enables the simultaneous achievement of high crystallinity and small aggregate size (≈35 nm) which overcomes the typical trade-off between these two critical parameters. The increase in crystallinity is attributed to the acidolysis process of acetic acid. After being modified by oleyl phosphate (OP), TiO2nanoparticles are well dispersed in acrylic monomers and successfully UV-cured into a hybrid film. The resulting hybrid films maintained high transmittance (>80%) in the range of 400-800 nm. The increased crystallinity of TiO2in the hybrid film raises its RI from 1.54 to 1.97. These superior optical properties directly benefit from the unique synergy of small size and high crystallinity achieved by the synthesis method, highlighting its potential for advanced optical device applications.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147674888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing metasurfaces have limitations in dynamic and multi-dimensional control, restricting their synergistic application in polarization multiplexing and dynamic focusing. To address this, this paper designs a dual-layer helicity-dependent tunable orbital angular momentum dielectric metalens operating at a wavelength of 1550 nm. This structure comprises a lower layer of silicon nanopillars (combining propagation and geometric phases) and an upper layer of Sb₂S₃ phase-change material nanopillars (providing tunable propagation phase). It achieves continuous adjustment of focal length through material phase transition without altering the physical structure. Upon incidence of linearly polarized (LP) light, two sets of focused spots with topological charges of ±1 can be simultaneously generated. For right-handed circularly polarized light incidence, a focal spot with a topological charge of -1 is generated, with a focal tuning range of 16.4 -20.0μm. For left-handed circularly polarized light incidence, a focal spot with a topological charge of +1 is generated, with a focusing range of 32.5-43.0μm. Simulations show that the focusing efficiencies for circularly and LP light are higher than 56.7% and 39%, respectively. This metalens possesses both polarization multiplexing and continuous focusing capabilities, holding potential applications in integrated optical vortex devices and quantum information processing, and is expected to drive the development of low-cost, large-scale optical vortex chips.","PeriodicalId":19035,"journal":{"name":"Nanotechnology","volume":"37 16","pages":""},"PeriodicalIF":2.8,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147722577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
