The Y-function method, although numerically robust, implicitly assumes drift–diffusion transport and attributes deviations in measured characteristics solely to gate-field-dependent mobility degradation. Here, we show that this assumption leads to a systematic breakdown of mobility interpretation in short-channel devices, even when polynomial Y-function analysis remains numerically stable. Temperature-dependent analysis of linear-regime transfer characteristics demonstrates that conventional Y-function-based extraction yields unphysical mobility attenuation parameters as transport departs from the diffusive limit. These anomalies do not arise from fitting instability or enhanced scattering, but from neglecting finite channel-length and injection-limited effects inherent to quasi-ballistic transport. By reinterpreting Y-function-extracted mobility within the Landauer transport formalism, we introduce a Landauer-consistent framework that explicitly separates scattering-limited mobility from ballistic constraints imposed by finite channel length. This minimal correction restores physically meaningful mobility parameters and enables self-consistent reproduction of both drain current and transconductance across the diffusive-to-quasi-ballistic transition, establishing a physically grounded approach for mobility analysis beyond the conventional applicability of the Y-function method.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" 6","pages":" 1726-1736"},"PeriodicalIF":6.6,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2026/nh/d6nh00069j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Indeed, dysregulated osteoclast activity is linked to pathological conditions such as Paget's disease, osteoporosis, and impaired fracture healing. Despite their importance in bone regeneration, few biomaterial-based strategies have been developed to alter osteoclast recruitment, differentiation, activity, or crosstalk with osteoblasts. To improve bone healing, we previously developed a drug delivery system (DDS) that expedites fracture repair. The DDS is composed of poly(styrene-<em>alt</em>-maleic anhydride)-<em>block</em>-poly(styrene) (PSMA-<em>b</em>-PS) functionalized with a peptide with inherent specificity to tartrate-resistant acid phosphatase (TRAP), a protein deposited by osteoclasts after bone injury (fracture, non-union, <em>etc.</em>). When loaded with a Wnt/β-catenin agonist (AR28), the TRAP binding peptide (TBP)-functionalized nanoparticle (TBP-NP<small><sub>AR28</sub></small>) enhanced fracture healing by promoting pro-regenerative polarization of macrophages, enhancing osteogenic differentiation, and expediting fracture healing. Given their crucial role in bone healing and proximity during fracture repair, here we investigated the impact of NP on osteoclasts. Murine bone marrow-derived osteoclasts treated with NPs exhibited decreased osteoclastogenesis due to downregulation of key osteoclast genes (NFATc, cFOS, and CTSK) and function as assessed by reduced bone resorption capacity. The inhibition of osteoclastogenesis and the reduction in osteoclast function demonstrated here suggest that TBP-NP<small><sub>AR28</sub></small> is a promising approach for improving bone regeneration by combining osteoclast inhibition with its previously reported effects on bone formation. This offers new therapeutic strategies for bone diseases characterized by dysregulation of bone homeostasis.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" 6","pages":" 1614-1628"},"PeriodicalIF":6.6,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13034928/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147571372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose a pH-regulated camouflage strategy that significantly enhances the encryption concealment of molecular systems. Using pH-regulated logical operation transformations, we establish a switchable cascaded logic operation strategy that implements a two-layer DNA molecular firewall access control system. By integrating two distinct camouflage rules, the system constructs four differentiated access modes.

Although the bulk-phase structures of these derivatives have been clarified, the molecular-level mechanism governing their assembly near solid interfaces remains elusive. Here, we performed all-atom molecular dynamics (MD) simulations to investigate three triptycene derivatives (Trip1, Trip2, and Trip3) with different alkoxy-chain substitution patterns, revealing their assembly structures, thermodynamic stabilities, and interfacial ordering processes. Our simulations showed that antiparallel molecular alignment is thermodynamically stable in bulk assemblies, whereas thin films preferentially adopt a parallel alignment, indicating that solid interfaces promote this orientation. Furthermore, thermal annealing of stair-stepped trilayers drove their transformation into flat bilayers and the growth of hexagonally ordered domains, quantified by radial distribution functions and hexatic order parameters. Comparative analysis demonstrated that alkoxy substitution patterns dictate packing density, structural order, and phase stability, in excellent agreement with experimental observations.
