    Structural Relaxation and Thermal Robustness of Electron-Beam Evaporated As2Se3 Films for Far-Infrared Heterogeneous Metalenses

    Weihang Qiu1, Bo Zhang2, Zhaofeng Gu2,*, Zijun Liu2, Xiang Shen2, Yimin Chen1,2,*

    Chalcogenide Letters, Vol.23, No.8, 2026, DOI:10.32604/cl.2026.089518 - 18 September 2026

    Abstract This study presents electron-beam evaporated As2Se3 films tailored for far-infrared heterogeneous metalenses. Characterization via X-ray diffraction and Raman spectroscopy reveals a structurally relaxed network in the films compared to bulk glass, resulting in enhanced infrared transmittance, a reduced refractive index, and a lower glass transition temperature. However, thermal expansion mismatch is found to induce cracking in thick films subjected to thermal cycling. The As2Se3/BaF2 system demonstrates superior adhesion, attributed to a minimal thermal expansion mismatch (Δα < 2.5 × 10−6°C−1). Notably, an 8 μm thick film endures over thirty rapid heating and liquid nitrogen quenching cycles without More >

    Research on Selenide Anode Materials for Alkali Metal Ion Batteries Based on First Principles

    Minghui Tan1,2, Fei Wang2,*, Shan Yuan1,2, Xinli Li1, Jingxia Gao2, Jinping Zhang2,*, Yong Zhang2, Lei Shi3

    Chalcogenide Letters, Vol.23, No.8, 2026, DOI:10.32604/cl.2026.088891 - 18 September 2026

    Abstract Li/Na/K-ion batteries show huge potential in next-generation energy storage systems, but the limited theoretical capacity of commercial graphite anodes and the relatively large radius of Na/K ions seriously restrict further development, making it urgent to develop new high-performance anode materials. This article begins with the research hotspots of selenide anode materials and systematically reviews the applications of DFT calculations in the field of Li/Na/K-ion battery selenide anodes, covering transition metal dichalcogenides (MoSe2, TiSe2), Janus structures (VSeTe, WSSe), transition metal carboselenides (Zr2Se2C, Sc2Se2C), multi-anion bridged phosphoselenides (MoScP2Se6), main-group element layered selenides (Si2Se2, SiSe2, β-GeSe, γ-GeSe, β-CSe, GeSeNS, SnS2(1−x)Se2x), as well… More >

    Emerging MoS2-Based Composite Approaches for the Detection of SF6 Decomposition Gases: A Review

    Huo Ye1, Jiantong Li2, Lingna Xu3,*

    Chalcogenide Letters, Vol.23, No.8, 2026, DOI:10.32604/cl.2026.087654 - 18 September 2026

    Abstract SF6 is the primary insulating and arc extinction medium in gas-insulated switchgear (GIS). Sulfur hexafluoride (SF6) decomposes to create diagnostic markers, such as sulfur dioxide (SO2), thionyl fluoride (SOF2), and hydrogen sulfide (H2S) when electrical problems occur, such as partial discharge and local overheating. Accurate quantification of these fault-marker gases is important for the early identification of insulation defects and the condition assessment of SF6-insulated equipment. Molybdenum disulfide (MoS2) is a well-known and atomically thin van der Waals semiconductor that has attracted considerable attention as a platform for gas-sensing applications. This is due to its large accessible surface area,… More >

    2D Chalcogenide Nanomaterial for Energy Storage Devices: Synthesis, Characterization and DFT Approach

    Holy Oghenewona Ovwiurhobo1, Marius O. Eji2, Adil Alshoaibi3, Ndanduleni Lethole4, Chawki Awada3, Shumaila Islam3, Nisrin Alnaim3, Fabian I. Ezema1,4,*

    Chalcogenide Letters, Vol.23, No.8, 2026, DOI:10.32604/cl.2026.086712 - 18 September 2026

    Abstract Several studies have reported a growing interest in nanomaterials beyond conventional graphite, driven by the rapid global demand for sustainable, high-performance energy storage. Among these materials, two-dimensional (2D) transition metal chalcogenides (TMCs), molybdenum- and tin-based systems such as molybdenum disulfide (MoS2) and tin (IV) disulfide (SnS2) in particular, have emerged as promising candidates for next-generation electrochemical energy storage devices (EESDs). This is owing to their unique X-M-X sandwich architectures, tunable electronic properties, and versatile intercalation chemistry. Despite several studies on 2D TMCs and their applications in EESDs, a gap still exists, as there is no comprehensive… More > Graphic Abstract

    Accountable NLP for Evidence-Grounded Decision Briefings: A Critical Review and Evaluation Framework

    Jihoon Moon*

    CMC-Computers, Materials & Continua, Vol.89, No.2, 2026, DOI:10.32604/cmc.2026.089115 - 15 September 2026

    Abstract Large language models and retrieval-augmented generation (RAG) systems are increasingly employed to transform evidence into decision-facing briefings, alerts, and recommendations. In these settings, explainability cannot be evaluated merely by fluency, readability, or factual correctness. A briefing may be factually correct while still being unsafe if it cites sources that do not substantiate the claim, suppresses uncertainty, converts correlational evidence into causal language, recommends an unauthorized action, or leaves no auditable path for human review. This review synthesizes 104 sources spanning explainable natural language processing (NLP), faithful explanation, hallucination and factuality evaluation, RAG, citation faithfulness, uncertainty… More >

    Disturbed Dynamic Analysis and Robust Decision-Making Control of Complex Networks

    Xiusen Wang1,*, Zheng Fang2, Jie Chen2,*

    CMC-Computers, Materials & Continua, Vol.89, No.2, 2026, DOI:10.32604/cmc.2026.088952 - 15 September 2026

    Abstract Complex networks in cyber–physical, transportation, and information infrastructures operate under topology variations, unmeasured disturbances, and limited actuation. This paper proposes robust disturbance-aware data-driven decision control (R-D3C), which couples a sliding-window graph-regularized estimator, disturbance-envelope adaptation, sparse intervention allocation, receding-horizon optimization, and a robust safety projection. The theory directly bounds the dynamic prediction regret of the implemented sliding-window estimator. A checkable sufficient condition for safety-filter feasibility is coupled with an explicit slack-and-backup fallback when the strict projection is infeasible. Practical input-to-state stability and sparse-allocation risk reduction are established. The nominal comparison uses 30 paired runs with standard More >

    Privacy-Preserving Edge Intelligence for Speaker Verification via Uncertainty-Aware Adaptive Feature Offloading

    Yongfeng Zhang1,*, Jie Chen2,*

    CMC-Computers, Materials & Continua, Vol.89, No.2, 2026, DOI:10.32604/cmc.2026.088561 - 15 September 2026

    Abstract Speaker verification on phones, wearables, and voice-enabled Internet-of-Things gateways must balance local privacy with reliable decisions under adverse audio. Existing privacy-preserving verification schemes generally protect a fixed representation, whereas edge-offloading policies usually adapt computation without attaching an explicit feature-disclosure budget; neither line alone coordinates trial uncertainty, communication state, and privacy expenditure. This paper presents privacy-preserving uncertainty-aware adaptive feature offloading (P-UAFO), an edge-intelligence framework that keeps raw audio local and transmits only clipped, projected, quantized, and Gaussian-perturbed intermediate features when their expected benefit justifies resource cost. Its online pipeline first estimates decision uncertainty and resource state,… More >

    A 5G-MEC-Enabled, Digital-Twin-Trained Framework for Autonomous Mobile Robots on the ROSMASTER R2 Platform

    Daniel Šolc1,*, René Ivančák1, Juraj Gazda1, Eva Chovancová1, Eugen Šlapák1, Gabriel Bugár2

    CMC-Computers, Materials & Continua, Vol.89, No.2, 2026, DOI:10.32604/cmc.2026.088224 - 15 September 2026

    Abstract Autonomous mobile robots increasingly rely on three tightly coupled capabilities: low-latency wireless connectivity, edge-side compute acceleration, and simulation-based pre-training of perception and control models. Each has been studied extensively in isolation, but their joint deployment on a single platform remains rare. This paper presents an integrated framework combining a private 5G Stand-Alone (5G SA) access network, a Multi-Access Edge Computing (MEC) layer with adaptive offloading, and a digital-twin training pipeline in NVIDIA Omniverse Isaac Sim. It is realised on the Yahboom ROSMASTER R2 with an NVIDIA Jetson Orin NX, a Quectel RM530N-GL 5G modem in… More >

    AMLHunter: An On-Chain Risky Address Identification Method Based on Temporally Consistent Transaction Semantic Constraints and Generative Augmentation

    Xiaolei Yin, Zihan Wang, Sanfeng Zhang*, Shouwei Li*

    CMC-Computers, Materials & Continua, Vol.89, No.2, 2026, DOI:10.32604/cmc.2026.088083 - 15 September 2026

    Abstract On-chain risky address identification is an important task in blockchain security analysis and digital asset risk management. In practical on-chain risk control, however, risky addresses are usually far fewer than benign ones. Fund flows also follow complex propagation paths and strict temporal orders, which makes it difficult for existing methods to handle class imbalance, structural semantic modeling, and information leakage under temporal split settings at the same time. To address these challenges, this paper proposes AMLHunter, an on-chain risky address identification method based on temporally consistent transaction semantic constraints and generative graph augmentation. AMLHunter first… More >
