We have built a framework that allows for tasks written with it to be run on multiple SPM systems. Our framework defines generic commands and data structures that are passed among separate software processes, with the final SPM commands sent to the microscope after passing through an SPM-specific translator. The use of configuration files allows automation logic to be further decoupled from experiment specifics. A mediation layer permits background tasks to intermittently control the microscope, fixing detected experiment problems.

Its wide availability, low cost, biodegradability, and non-toxic nature make it a promising candidate for sustainable material development across various industries. This review focuses on the extraction and isolation of cellulose from different types of biomass waste, including agricultural residues, forestry byproducts, and industrial waste. Several conventional and advanced methods for cellulose extraction were also explored such as acid hydrolysis, enzymatic hydrolysis, oxidation, and mechanical or solvent-based techniques. Besides that, this review highlights the role of cellulose in photocatalytic applications, where its high surface area, structural porosity, and abundance of functional groups enable it to act as an effective support matrix for photocatalysts such as ZnO, TiO₂, Cu₂O, and various hybrid nanocomposites. Through stabilizing nanoparticles, preventing their aggregation and contributing to pollutant adsorption, cellulose enhances the overall efficiency of photocatalytic systems, improving its performance under a wide range of light sources. Moreover, cellulose-supported systems often show enhanced recyclability and mechanical durability, making them suitable for repeated use in wastewater treatment and environmental remediation. The relationship between cellulose's structural properties and photocatalytic functionality offers a green and efficient solution to pressing environmental challenges.

This review highlights recent progress in junction engineering strategies for BEF enhancement. Homojunctions extend interfacial potential fields into the bulk through controlled doping and orientation modulation, thereby suppressing nonradiative recombination and improving carrier extraction. Gradient junctions introduce continuous compositional or bandgap tilts across the film thickness, enabling depth-extended electric fields and improved spatial continuity of charge transport. By contrast, 2D/3D heterojunctions exploit interfacial dipole formation, intrinsic polarization, and phase-penetration effects to amplify and homogenize the BEF, while simultaneously improving energy-level alignment and defect passivation. We systematically compare these strategies within a unified framework of BEF descriptors, magnitude, penetration depth, directionality, and spatial continuity. Special emphasis is placed on the potential for synergistic integration of multiple junction architectures and on the development of mild, process-compatible fabrication routes. Ultimately, optimizing the BEF provides a powerful lever for advancing power conversion efficiency, open-circuit voltage, and long-term operational stability in state-of-the-art PSCs, while avoiding the introduction of parasitic energy barriers.</p>","PeriodicalId":8802,"journal":{"name":"Beilstein Journal of Nanotechnology","volume":"17 ","pages":"602-621"},"PeriodicalIF":3.5,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13159266/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147925971","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}

Herein, we systematically investigate the sub-nanoscale friction behaviors of atomically thin molybdenum disulfide (MoS₂) under controlled loads using a calibrated atomic force microscope (AFM), with a focus on quantifying the strengthening effect and sub-nanoscale stick-slip motion. Our results reveal that the nanoscale strengthening effect intensifies with increasing applied load but weakens as the number of MoS₂ layers increases, attributed to the reduced out-of-plane flexibility in thicker films. Critically, we identify the slip distance during the slip phase as a reliable metric for sub-nanoscale stick-slip motion. The slip distance increases with the frequency of sub-nanoscale stick-slip events and exhibits a load-dependent transition, remaining nearly constant under low loads before increasing with higher loads, and ultimately decreasing at ultrahigh loads. This transition arises from two competing mechanisms: under low loads, the evolution of interfacial contact quality dominates the strengthening effect and suppresses sub-nanoscale stick-slip motion. Under moderate-to-high loads, the puckering effect becomes dominant, enhancing sub-nanoscale stick-slip events and increasing slip distance. At ultrahigh loads, the nanoscale strengthening effect transitions to static friction, which quenches sub-nanoscale stick-slip motion and reduces slip distance. Furthermore, the load-dependent sub-nanoscale stick-slip motion is closely correlated with changes in tip-MoS₂ contact area and contact geometry, both modulated by load and MoS₂ layer thickness. These findings advance 2D material tribology from the nanoscale to sub-nanoscale, providing critical insights for designing low-friction coatings and high-performance micro/nanoelectromechanical systems (MEMS/NEMS).</p>","PeriodicalId":8802,"journal":{"name":"Beilstein Journal of Nanotechnology","volume":"17 ","pages":"586-597"},"PeriodicalIF":3.5,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13159262/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147926066","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}
