Abstract:
Abstract As nanoscale reinforcements, the graphene and graphene oxide nanoplates exhibit distinct mechanical and physical properties. The determination of the effective elasto-plastic behavior of nanoplate/ceramic nanocomposites and the different filling effects of graphene and graphene oxide nanoplate deserve systematic investigation. In this work, we intend to uncover how the graphene and graphene oxide nanoplates affect the macroscopic elasto-plastic characteristics of ceramic matrix nanocomposites and what differences in both nanoplates enhancements. A homogenization model is first utilized for determining the effective elastic parameters of nanoplate/ceramic composite with a perfect interface. Then the slightly weakened interface model is introduced to characterize the sliding effects of nanoplates in a ceramic matrix, and the effective elastic parameters of such nanoplates filled composites incorporating the interfacial sliding effects are explicitly formulated. Furthermore, a nonlinear micromechanics model is developed to investigate the macroscopic elastoplasticity and the yield behavior of graphene and graphene oxide nanoplate-filled ceramic nanocomposites subjected to confining pressure. The filling effects of the two kinds of nanoplates on the mechanical properties of such nanocomposite are comparatively examined. The calculated results demonstrate that types of the nanoplates and the imperfect interfaces between nanoplates and ceramic matrix have significant influences on the effective elasto-plastic behaviors of the nanoplate composites.

Abstract:
This article presents an exact analysis for the three-dimensional buckling problem of embedded multilayered magnetoelectroelastic and simply supported nanoplates/graphene sheets with nonlocal effect. The interaction between the multilayered nanoplates/graphene sheets and their surrounding medium is simulated by a Pasternak-type foundation. The critical loads for embedded multilayered magnetoelectroelastic nanoplates/graphene sheets under uniaxial and biaxial compression at small scale are then derived by solving the linear eigensystem and making use of the propagator matrix method. A comparison between the present anisotropic three-dimensional model and previous results (an asymptotic nonlocal elasticity theory for single elastic graphene sheet and classical orthotropic plate theories) is made to show the effectiveness and correctness of the present anisotropic three-dimensional model. Numerical examples are then presented for the variation of the dimensionless critical buckling loads for the homogeneous elastic graphene sheet with nonlocal effect, the homogeneous orthotropic thick plate without nonlocal effect, and the sandwich magnetoelectroelastic nanoplates made of piezoelectric and magnetostrictive materials with nonlocal effect. Furthermore, the effects of the thickness of nanoplates, nonlocal parameter, Winkler stiffness, and shear modulus of the elastic medium on the critical load of sandwich magnetoelectroelastic nanoplates/graphene sheets are demonstrated. These results should be very useful as benchmarks for the future development of approximate nanoplate/graphene sheet theories and numerical methods for modeling and simulation of multilayered nanoplates/graphene sheets with nonlocal effect.

Abstract:
Purpose This study aims to the preparation and tribological characteristics of graphene/triangular copper nanoplate composites (abbreviated as GN/Cu nanoplates) as grease additive and clarifies the growth mechanism and tribological mechanism of GN/Cu nanoplates by different analysis methods. In this paper, it is expected to alleviate the problems of easy aggregation and poor dispersion stability of graphene in lubricants and provide theoretical support for the application of graphene and its composites in the tribology field. Design/methodology/approach In this study, the GN/Cu nanoplates have been successfully prepared by the electrostatic self-assembly method. The structural characteristics of GN/Cu nanoplates were analyzed via transmission electron microscopy and X-ray diffraction. Then the tribological properties of GN/Cu nanoplates were investigated under different loads with SRV-IV [Schwingung, Reibung, Verschleiß (German); oscillating, friction, wear (English translation)] tribotester. White-light interferometry was applied to quantify the wear loss of the disk. The element chemical state on worn surfaces was analyzed by an X-ray photoelectron spectroscope to clarify the tribological mechanism of graphene composites. Findings The electrostatic force between the negative charge of graphene and the positive charge of triangular copper nanoplates promotes the self-assembly of GN/Cu nanoplates. With the addition of GN/Cu nanoplates, the wear loss and average friction coefficient under the load of 200 N have been decreased by 72.6% and 18.3%, respectively. It is concluded that the combined action of graphene deposition film and the copper melting film formed on the worn surface could effectively improve the antiwear ability and friction reduction performance of the grease. Originality/value This manuscript fulfills a new approach for the preparation of GN/Cu nanoplates. At the same time, its tribological properties and mechanism as a lubricating additive were studied which provide theoretical support for the application of graphene and its composites in the tribology field.

Abstract:
This paper aims to study the hygrothermal buckling of smart graphene/piezoelectric circular nanoplates lying on an elastic medium and subjected to an external electric field. The circular nanoplates are made of piezoelectric polymer reinforced with graphene platelets that are uniformly distributed through the thickness of the nanoplate. The material properties of the nanocomposite plate are determined based on the modified Halpin-Tsai model. To capture the nanoscale effects, the nonlocal strain gradient theory is applied. Moreover, the principle of virtual work is employed to establish the nonlinear stability equations in the framework of classical theory. The differential quadrature method is utilized to solve the governing equations. Among the important aims of the paper is to study the influences of various parameters such as graphene weight fraction, elastic foundation parameters, external applied electric field, humid conditions, and boundary conditions on the thermal buckling of the smart nanocomposite circular nanoplates. It is found that the increase in graphene components and elastic foundation stiffness enhances the strength of the plates; therefore, the buckling temperature will increase.

Abstract:
Graphene-related two-dimensional nanomaterials possess very technically promising characteristics, but gaps exist regarding their potential adverse health effects. Based on their nano-thickness and lateral micron dimensions, nanoplates exhibit particular aerodynamic properties, including respirability. To develop a lung-focused, in vitro/in vivo screening approach for toxicological hazard assessment, various graphene-related nanoplates, i.e., single-layer graphene (SLG), graphene nanoplatelets (GNP), carboxyl graphene, graphene oxide, graphite oxide and Printex 90® (particle reference) were used. Material characterization preceded in vitro (geno)toxicity screening (membrane integrity, metabolic activity, proliferation, DNA damage) with primary rat alveolar macrophages (AM), MRC-5 lung fibroblasts, NR8383 and RAW 264.7 cells. Submerse cell exposure and material-adapted methods indicated material-, cell type-, concentration-, and time-specific effects. SLG and GNP were finally chosen as in vitro biologically active or more inert graphene showed eosinophils in lavage fluid for SLG but not GNP. The subsequent 28-day inhalation study (OECD 412) confirmed a toxic, genotoxic and pro-inflammatory potential for SLG at 3.2 mg/m3 with an in vivo-ranking of lung toxicity: SLG > GNP > Printex 90®. The in vivo ranking finally pointed to AM (lactate dehydrogenase release, DNA damage) as the most predictive in vitro model for the (geno)toxicity screening of graphene nanoplates.

Abstract:
A hybrid heat-conducting filler based on graphene nanoplates and multi-walled nanotubes was obtained to increase the thermal conductivity of an epoxy binder, exhibiting a synergistic effect. This effect is achieved due to the embedding of multi-walled nanotubes between graphene nanoplates and the formation of effective percolation networks in the composite. The dependence of an increase in the thermal conductivity of an epoxy composite on the mass ratio of graphene nanoplates and multi-walled nanotubes in a mixture of a hybrid filler has been established. The effect of the hybrid filler concentration in the epoxy matrix and the mixing method of graphene nanoplates and multi-walled nanotubes on the thermal conductivity of the composite was found. A synergistic effect between graphene nanoplates and multi-walled nanotubes has been demonstrated, leading to a sixfold increase in the thermal conductivity of epoxy composites at a filler concentration of 5 wt%.

Abstract:
Graphene loaded hexagonal CuS/Ag2S nanoplates have been successfully synthesized. Scanning electron microscopy and transmission electron microscopy observations show that hexagonal CuS/Ag2S nanoplates are tightly anchored onto graphene. The experimental results show that these nanocomposites have a highly visible-light photocatalytic performance. The high visible photocatalytic activities can be attributed to direct photoinduced interfacial charge transfer in the hexagonal CuS/Ag2S nanoplates and the further electrons transfer from CuS/Ag2S to graphene.

Abstract:
This work presents the buckling investigation of embedded orthotropic nanoplates by using a new hyperbolic plate theory and nonlocal small-scale effects. The main advantage of this theory is that, in addition to including the shear deformation effect, the displacement field is modeled with only three unknowns and three governing equation as the case of the classical plate theory (CPT) and which is even less than the first order shear deformation theory (FSDT) and higher-order shear deformation theory (HSDT). A shear correction factor is, therefore, not required. Nonlocal differential constitutive relations of Eringen is employed to investigate effects of small scale on buckling of the rectangular nanoplate. The elastic foundation is modeled as two-parameter Pasternak foundation. The equations of motion of the nonlocal theories are derived and solved via Navier's procedure for all edges simply supported boundary conditions. The proposed theory is compared with other plate theories. Analytical solutions for buckling loads are obtained for single-layered graphene sheets with isotropic and orthotropic properties. The results presented in this study may provide useful guidance for design of orthotropic graphene based nanodevices that make use of the buckling properties of orthotropic nanoplates. Verification studies show that the proposed theory is not only accurate and simple in solving the buckling nanoplates, but also comparable with the other higher-order shear deformation theories which contain more number of unknowns. Keywords: Buckling; orthotropic nanoplates; a simple 3-unknown theory; nonlocal elasticity theory; Pasternak’s foundations. * Corresponding author; Email-tou_abdel@yahoo.com

Abstract:
L’étude analytique proposée porte sur le comportement en vibration de nanotubes de carbone et de nanoplaques de graphène. Pour ce faire, il s’agira dans un premier temps d’étudier les traditionnelles théories de Bresse-Timoshenko pour les poutres et de Uflyand-Mindlin pour les plaques. Des modèles de cisaillement alternatifs sont développés, notamment basés sur des approches asymptotiques issues du milieu élastique tri-dimensionnel. Les interactions interatomiques, ne pouvant pas être négligées à une échelle nanoscopique, seront ensuite prises en compte dans les modèles à travers la présence de paramètres non locaux. Ainsi, différentes approches continues seront considérées : phénoménologiques, asymptotiques et continualisées. Ce dernier type d’approche est récent et est basé sur le développement de modèles continus à partir des équations discrètes de poutres et plaques épaisses et de l’utilisation des approximants de Padé et des développements en séries de Taylor. Pour chaque modèle développé au cours de cette étude, les fréquences propres seront déterminées pour différentes conditions aux limites. Il s’agira ainsi de définir le meilleur cadre pour l’utilisation de chaque modèle et de déterminer l’éventuelle supériorité d’un modèle sur les autres
This thesis deals with the analytical study of vibration of carbon nanotubes and graphene plates. First, a brief overview of the traditional Bresse-Timoshenko models for thick beams and Uflyand- Mindlin models for thick plates will be conducted. It has been shown in the literature that the conventionally utilized mechanical models models overcorrect the shear effect and that of rotary inertia. To improve the situation, two alternative versions of theories of beams and plates are proposed. The first one is derived through the use of equilibrium equations and leads to a truncated governing differential equation in displacement. It is shown, by considering a power series expansion of the displacement, that this is asymptotically consistent at the second order. The second theory is based on slope inertia and results in the truncated equation with an additional sixth order derivative term. Then, these theories will be extended in order to take into account some scale effects such as interatomic interactions that cannot be neglected for nanomaterials. Thus, different approaches will be considered: phenomenological, asymptotic and continualized. The basic principle of continualized models is to build continuous equations starting from discrete equations and by using Taylor series expansions or Padé approximants. For each of the different models derived in this study, the natural frequencies will be determined, analytically when the closed-form solution is available, numerically when the solution is given through a characteristic equation. The objective of this work is to compare the models and to establish the eventual superiority of a model on others

Abstract:
Phase change materials (PCMs) have the ability to store thermal energy as latent heat over a nearly isothermal temperature range. Compared to sensible heat storage, properly chosen PCMs can store an order of magnitude more energy when undergoing phase change. Organic PCMs present several advantages including their non-corrosive behavior and ability to melt congruently, which result in safe and reliable performance. Because of these qualities, organic PCMs have been proposed for use in latent heat thermal storage systems to increase the energy efficiency or performance of various systems such as cooling and heating in buildings, hot water heating, electronics cooling, and thermal comfort in vehicles. Current performance is hindered by the low thermal conductivity, which significantly limits the rate of charging and discharging. Solutions to this challenge include the insertion of high conductivity nanoparticles and foams to increase thermal transport. However, performance validation remains tied to thermal conductivity and latent heat measurements, instead of more practical metrics of thermal charging performance, stability of the composite, and energy storage cost. This thesis focuses on the use of graphite nanoplatelets and graphite foams to increase the thermal charging performance of organic PCMs. Stability of graphite nanoplatelets in liquid PCM is realized for the first time through the use of dispersants and control of the viscosity, particle distribution, and oxidation. Thermal charging response of stable graphite nanoplatelet composites is compared to graphite foam composites. This study includes a correlation of thermal conductivity and latent heat to material concentration, geometry, and energy storage cost. Additionally, a hybrid PCM storage system of metal foam combined with graphite nanoplatelet PCM is proposed and evaluated under cyclic thermal conditions.

Abstract:
Environmental changes and extreme climate-related events are mainly attributed to greenhouse gas (GHG) emissions and are becoming a growing concern. The reported scientific evidence, highlighting such interrelationships, has convinced researchers to look for clean energy sources and improve operational efficiencies, and capture and convert the waste heat into electricity. Since almost two-thirds of energy is converted to heat and wasted, the recovery of waste heat will boost savings in fossil fuel consumption as an abundant source of energy. In this regard, thermoelectric (TE) compounds can be employed to convert the waste heat into electricity, thereby increasing the efficiencies of energy generating operations. Such an approach is even applicable to renewable energy (RE) sources. However, the applications of the thermoelectric converters necessitate the development of advanced, efficient thermoelectric materials with a high level of thermomechanical stability. This doctoral research project aims to develop and modify thermoelectric compounds by manipulating their microstructure and improving their mechanical properties by reinforcement with graphene nanoplates (GNPs). To the best of our knowledge, there is no specific report in the open literature to determine the reinforcing effects of graphene nanofillers (e.g., GNPs) on thermoelectric products. There is a lack of a comprehensive assessment in the scientific and industrial communities in evaluating the advantages and drawbacks of GNPs, as the reinforcing agent on TE compounds. In this dissertation, to assess the performance of the GNPs, three potential thermoelectric compounds, namely MnTe, CoVSn, and CuSbTe2, have been investigated. These designated compounds address the requirements for covering an extended working temperature range from low to high, examining various crystal structures (e.g., Chalcogenides and half-Heusler), and developing environmentally-friendly (i.e., lead-free) TE products. The bulk samples with the addition of small quantities of GNPs (0.25, 0.5, 0.75, and 1 wt. %) were synthesized using powder metallurgy and fabricated by spark plasma sintering (SPS). The thermoelectric factors, magnetic behavior, microstructure, and mechanical properties of the samples were evaluated and analyzed. Grain growth inhibition is the main consequence of the reinforcing GNPs, which results in an enhancement in the thermoelectric and mechanical characteristics of the nominated TE products. Scattering of electrical carriers and phonons due to the precipitation of the reinforcing GNPs in the matrix, thus providing a higher density of microstructural boundaries, improves the thermoelectric properties. Furthermore, microstructural manipulation, such as crystal/particle size reduction caused by the segregation of the reinforcing GNPs as a second phase in the matrix, enhances the mechanical characteristics of TE compounds, for example, the fracture toughness (𝐾𝐼𝐶) and hardness.

The purpose of this research is to adopt mixture of Benzoxazine and epoxy resin as matrix and mixture of multi-wall nanotubes and graphene Nanoplates as nano-reinforcement through modification between Benzoxazine and epoxy resin and utilizing nano-reinforcements, to improve the mechanical properties and fatigue life of composite. The study investigates: (1)The influence of Benzoxazine content of resin on mechanical properties; (2)The impact of reinforcing effect and concentration when adopting nanotubes or graphene Nanoplates individually as reinforcement; (3)The best ratio of the mixture of nanotubes and graphene Nanoplates; (4)The influence of concentration of reinforcements in best proportion on mechanical strength and fatigue life of laminated composites. The experimental results show that addition of Benzoxazine can greatly improve tensile and flexural properties, but the material would become hard and brittle with drop of impact strength at the same time. Nanotubes or graphene have beneficial efficiency on materials, because they both can occur micro crack deviation and increase energy to failure. However, when the concentration of nano-reinforcement exceeds certain concentration, the aggregation phenomenon should incur stress concentration, thus the mechanical properties will decrease. According to the experimental result of mixing nano-reinforcement, the 9:1 mixing ratio of nanotubes and graphene Nanoplates is the best ratio for enhancing the mechanical properties. The reinforcements in best ratio added to the laminated composites show good enhancement, improving the tensile strength by 22.28%, the flexural strength by 9.64%, the impact strength by 33.75% and the torsion fatigue life by about three times in contrast with those of neat resin laminated composites. The properties are improved, because the nano-reinforcements enhance the interfaces between matrix and fibers, thus the load can be effectively transferred to fibers. This mechanism is confirmed by observing SEM images of failure surface.

Abstract:
Abstract. Structural health monitoring has proven to be a dependable source for ensuring the integrity of the structure. It also aids in detecting and estimating the progression of cracks and the loss of structural performance. The most compelling components in the structural health monitoring system are sensing material and sensor technology. In health monitoring systems, fiber optic sensors, strain gauges, temperature sensors, shape memory alloys, and other types of sensors are commonly used. Even though the sensors bring monetary value to the system, they have some apparent drawbacks. As a result, self-sensing cement composite was established as a sensor alternative with better endurance and compatibility than sensors. Carbon nanotubes, nanofibers, graphene nanoplates, and graphene oxide are carbon-based nanomaterials with unique mechanical and electrical properties. As a result, this review comprises a complete assessment of the fresh, mechanical, and electrical properties of self-sensing cement composite developed using carbon-based nanoparticles. The research also focuses on the self-monitoring performance of cement composite in concrete beams, both bulk and embedded, by graphing the deviation of fractional change in resistivity with strain. The network channel development of carbon-based nanomaterials in cement composites and their characterization acquired using scanning electron microscopy (SEM), and X-Ray diffraction spectroscopy (XRD) research are also comprehensively discussed. According to the study, increasing carbon-based embedment decreased the relative slump and flowability while increasing the composite's compressive, split tensile, flexural, and post-peak performance. Also, the amount of carbon in the carbon-based nanomaterial directly relates to the composite's conductivity. As a result, the development of piezoresistive and sensing capabilities in carbon-based self-sensing cement composites not only improves mechanical and conductive properties but also serves as a sensor in structural health monitoring of flexural members.

Abstract:
Abstract With the increasing demand for higher performance and progressive miniaturization of electronic packages, power densities and the attendant thermal dissipation requirements are expected to escalate. One of the important strategies to ensure reliable operation at the device and die (chip) levels is the use of Thermal Interface Materials (TIMs) to reduce the thermal resistance between the chip and the heat sink. In this study, we have carried out an experimental investigation to characterize thermal conductance of TIMs composed of commercially available graphene (c-rGO), graphene nanoplatlets (GNPs) of different lateral sizes (5, 15 and 25 μm), and our in-house produced thermally reduced graphene oxide at 600°C (T-rGO-600). These additives were loaded in a silicone rubber matrix where their loading fraction was fixed at 2% by weight. Thermal conductance of the resulting TIMs was determined by measuring heat flow, in steady state, through a TIM sandwiched between two metal blocks. The thermal conductance values representing the combined resistance of the composite material and the contact resistances between the TIM and the metal blocks were measured at different heat flux levels across the TIM. The results show that the thermal conductance values were independent of the heat load across the TIM as well as the TIM temperature. Further, a detailed investigation of the surface functionality and structural properties has revealed that the in-house produced T-rGO-600 has superior thermal conductance when compared to the above-mentioned carbonaceous nanomaterials, which are considered as potential candidates for enhancing thermal performance of TIMs. The data demonstrates that this result is attributable to the formation of the surface functional groups and the associated morphological changes during the reduction of graphene oxide to the T-rGO-600. Among the different GNPs tested, the GNP-15 exhibited superior thermal performance compared to the GNP-5 and GNP-25 samples.
