Abstract The convergence of artificial intelligence (AI) and nanotechnology has substantially transformed the discovery, design, synthesis, characterization and biomedical application of nanomaterials. This review provides a structured overview of AI applications in nanotechnology, including data-driven nanomaterial d…
Ultrahigh-strength steels often suffer from limited resistance to plastic instability, restricting lightweight structural applications. Here, a 1.5 GPa quenching and partitioning (Q&P) steel containing 10 vol.% austenite exhibits appreciable ductility and sustained work hardening. Combining in-situ neutron diffraction…
ABSTRACT A key challenge in airworthiness of composite aircraft is understanding the thermo‐mechanical response and failure of carbon fiber reinforced polymer (CFRP) in in‐flight fire. A sequentially coupled thermal‐stress analysis with a three‐dimensional thermal response model incorporating anisotropic thermal condu…
The study presents an integrated assessment of water quality in wadis of the Bizerte Lagoon catchment (Northern Tunisia), using benthic diatom assemblages. Seasonal sampling was conducted between winter 2023 and winter 2024 in three wadis exposed to varying anthropogenic pressures. In each wadi, upstream and downstrea…
The emergence of nanotechnology has led to a rapid increase in intentional and unintentional exposure to engineered nanoparticles (NPs), raising significant concerns over their impact on humans, animals, and ecosystems. Nanotoxicology has evolved to assess these adverse effects, but the field faces key challenges incl…
The present paper addresses models of non-local materials and, in particular, flexoelectric materials as dielectrics with higher-order gradients. While the literature develops the subject through variational formulations, here the modelling is developed within a thermodynamic framework with a general form of the Claus…
Analysis code, derived data and manuscript source for a study of spatial order in Cahn–Hilliard coarsening. In a phase-separating system with a locally conserved order parameter, the concentration field is hyperuniform, with Sc(k) ~ k⁴, while the point pattern of domain centroids is not: S(k→0) settles on a plateau ne…
Tungku peleburan aluminium tipe krusibel skala kecil dan menengah umumnya mengalami kehilangan panas (heat loss) yang signifikan melalui dinding akibat konduksi, sehingga menurunkan efisiensi termal dan meningkatkan konsumsi bahan bakar. Penelitian ini bertujuan mengoptimalkan geometri tungku peleburan aluminium berka…
Abstract To address the critical demand for high-performance hydrogen storage materials in the hydrogen economy, we systematically investigate the structural, electronic, and hydrogen storage performance of pure and charge-modulated Sun-graphyne (SGY) monolayers using first-principles calculations based on the PBEsol…
This revised article addresses Q0039, 'Learn from failed reactions and negative experimental data?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Failure-Informed Reaction Boundary Model, uses positive outcome y=1, experimentally failed o…
국문 초록 주사전자현미경(SEM)의 표준 구성은 시료를 진공에 두는 것을 전제하며, 이 전제는 60년간 자명한 배경으로 취급되어 왔다. 그러나 관찰 수요가 첨단 패키징의 대형·이종 시료와 함습 유기물·액상·부도체로 확장되면서, '측정 불가' 판정의 상당수가 시료의 물리 한계가 아니라 환경 전제의 산물임이 드러나고 있다. 본 논문은 이 문제를 정식화한다. (1) 진공 전제가 시료를 배제하는 기제를 네 유형 — E1 기하 배제(챔버·스테이지 적재 한계), E2 표면 배제(부도체 대전과 코팅 강제), E3 상태 배제(아웃개싱·수분 이탈·변형 등 진공 유발 변질), E4…
Abstract Crystallization in microgravity has been extensively investigated because of its potential to enhance crystal quality compared to terrestrial conditions. While early efforts were primarily directed toward single-crystal growth for structural studies, increasing attention is now being given to its relevance fo…
DRAM capacitor dielectrics face a hard leakage×EOT scaling constraint below the 1z-nm node (IMW 2020); for 30 years industry has responded by doping-pinning the tetragonal phase of high-k dielectrics (ZrO₂/HfO₂-based) to stabilize it—yet this long-standing practice lacks a unified criterion language. Using a field-the…
Abstract We present the Boston Open-Shell Transition Metal Complex (BOS-TMC) data set, a set of density functional theory (DFT) properties for 159k experimentally characterized mononuclear transition metal complexes (TMCs) in multiple spin states with a range of formal charges derived from the Cambridge Structural Dat…
Metal hydroxides have drawn immense attention as robust materials for supercapacitor electrodes with enhanced electrochemical performance, desired electroactive structural, and compositional properties. Among these hydroxides, nickel hydroxide nanostructures offer advantages over other nanomaterials due to their signi…
