Abstract The discovery of graphene and its unique physicochemical properties has catalyzed intensive research into alternative two-dimensional (2D) materials, with a view to their prospective applications in diverse fields of physics, chemistry, and materials science. In this context, there is a notable scientific interest in developing computationally efficient theoretical approaches capable of reliably estimating key parameters of organic films deposited on 2D surfaces. This objective necessitates a rigorous selection and validation of appropriate computational methods, ensuring an optimal balance between computational cost and predictive accuracy.

Abstract During the preparation of carbon fiber reinforced carbon matrix (C/C) composites from resin based precursors, the glassy carbon derived from resin pyrolysis is difficult to graphitize into an ordered structure during carbonization and graphitization, which adversely affects the performance of C/C composites. To enhance the transformation of resin-derived carbon into an ordered structure, we employed a structurally ordered graphene-based material to modify a phenolic resin/carbon fiber precursor and designed two composite modification structures that are straightforward to implement in processing. The internal microstructure of the composites was characterized by XRD and SEM. The results indicate More >

Abstract Vacancy defects in graphene are inevitably introduced during the fabrication of graphene-reinforced metal matrix composites through mechanical processing, chemical reactions, or in-service environmental exposure. Despite their prevalence, the precise atomic-scale impact of these vacancies on dislocation motion, strengthening mechanisms, and failure behavior remains incompletely understood. To address this gap, we employ molecular dynamics simulations to construct aluminum-graphene interface models featuring systematically varied vacancy defect concentrations, enabling a detailed investigation of dislocation–interface interactions and the underlying reinforcement and failure mechanisms under shear deformation. Compared to pristine graphene, interfaces containing vacancy defects exhibit significantly enhanced out-of-plane buckling… More >

Abstract Graphene oxide (GO) has shown great potential in agricultural applications, however, its concentration-dependent effects on cucumber (Cucumis sativus L.) growth, nutrient absorption, and root architecture remain unclear. In the present study, a hydroponic experiment was conducted with different GO concentrations (0.5, 1.0, and 2.0 mg L⁻¹) and setting the non-GO treatment (0.0 mg L⁻¹) as the control for cucumber plants (cv. Qingbaizao). The results showed that low to moderate concentrations (0.5–1.0 mg L⁻¹) significantly promoted cucumber growth, increased shoot and root biomass, enhanced the accumulation of nitrogen, phosphorus, and potassium, and optimized root architecture by increasing cellulose and… More >

Abstract An eco-friendly one-pot hydrothermal method was developed to synthesize molybdenum disulfide/graphene oxide (MoS₂/GO) nanocomposites for high-performance supercapacitor applications. X-ray diffraction (XRD) analysis confirmed the presence of the MoS₂ crystalline phase, with reduced peak intensities upon GO incorporation, indicating suppressed crystallite growth. Scanning electron microscopy (SEM) revealed rod-like MoS₂ structures uniformly distributed across layered GO sheets, and energy-dispersive spectroscopy (EDS) confirmed the presence of Mo, S, C, and O elements. Raman and FTIR analyses verified strong interfacial interactions between MoS₂ and GO. Brunauer–Emmett–Teller (BET) measurements revealed a mesoporous structure with a specific surface area of ~31.7 m² g⁻¹ and… More >

Abstract Graphene has excellent mechanical, electrical and optical properties, which make it an ideal reinforcement phase for aluminum matrix composites. However, graphene is easy to agglomerate and has poor wettability with the aluminum matrix, resulting in unsatisfactory effects when added to the aluminum matrix. In this paper, the effects of transition metals (Cu, Ni, Co) on the bonding properties at the graphene/aluminum interface were systematically investigated using first-principles calculations. The computational results reveal significant differences in the effects of various metals and their crystal plane orientations on interface stability and bonding strength. Among Cu, Ni, Co… More >

Abstract Investigating the deformation behavior of graphene-reinforced composite structures holds significant engineering implications, while the rapid advancement of machine learning has introduced new technical approaches to structural bending analysis. In this study, we investigate the mechanical bending behavior of graphene origami (GOri)-enabled auxetic metamaterial beams using a physics-informed neural network (PINN). GOri-enabled auxetic metamaterials represent an innovative composite system characterized by a negative Poisson’s ratio (NPR) and superior mechanical performance. Here, we propose a composite beam model incorporating the modified coupled stress theory (MCST) and employing the PINN method to solve higher-order bending governing equations. Compared More >

Abstract In this study, the multi-scale (meso and macro) modelling was used to predict the electric response of the material. Porosity was introduced through a sugar-templating process to enhance compressibility and sensitivity. Mean-field homogenization was employed to predict the electrical conductivity of the nanocomposites, which was validated experimentally through I–V characterisation, confirming stable Ohmic behavior. The homogenised material parameters were incorporated into COMSOL Multiphysics to simulate diaphragm deflection and capacitance variation under applied pressure. Experimental results showed a linear and stable capacitance response at the force magnitude of 0–7 N. The Graphene nanoplatelets (GnP)–Polydimethylsiloxane (PDMS) sensor demonstrated More >

Abstract In this work, a computational modelling and analysis framework is developed to investigate the thermal buckling behavior of doubly-curved composite shells reinforced with graphene-origami (G-Ori) auxetic metamaterials. A semi-analytical formulation based on the First-Order Shear Deformation Theory (FSDT) and the principle of virtual displacements is established, and closed-form solutions are derived via Navier’s method for simply supported boundary conditions. The G-Ori metamaterial reinforcements are treated as programmable constructs whose effective thermo-mechanical properties are obtained via micromechanical homogenization and incorporated into the shell model. A comprehensive parametric study examines the influence of folding geometry, dispersion arrangement, More >
