“…Recently, carbon-based reinforcements have been used to impart improvements in the properties of Al-MMCs [ 19 ]. Carbon materials such as carbon fibers [ 20 , 21 ], graphite [ 22 , 23 ], carbon nanotubes (CNTs) [ 24 , 25 ], graphene (G) [ 26 , 27 ] and graphene oxide (GO) [ 28 , 29 ] have been used as reinforcements in Al-MMCs. In graphene-reinforced aluminum matrix nanocomposites, an improvement of 79, 49 and 44% in yield strength, ultimate strength, and Vickers hardness have been reported with 1 wt.% GO addition, and the increase in GO content has led to grain refinement of the composite [ 30 ].…”

Aluminum matrix composites are among the most widely used metal matrix composites in several industries, such as aircraft, electronics, automobile, and aerospace, due to their high specific strength, durability, structural rigidity and high corrosion resistance. However, owing to their low hardness and wear resistance, their usage is limited in demanding applications, especially in harsh environments. In the present work, aluminum hybrid nanocomposite reinforced with alumina (Al2O3) and graphene oxide (GO) possessing enhanced mechanical and thermal properties was developed using spark plasma sintering (SPS) technique. The focus of the study was to optimize the concentration of Al2O3 and GO content in the composite to improve the mechanical and thermal properties such as hardness, compressive strength, heat flow, and thermal expansion. The nanocomposites were characterized by FESEM, EDS, XRD and Raman spectroscopy to investigate their morphology and structural properties. In the first phase, different volume percent of alumina (10%, 20%, 30%) were used as reinforcement in the aluminum matrix to obtain (Al+X% Al2O3) composite with the best mechanical/thermal properties which was found to be 10 V% of Al2O3. In the second phase, a hybrid nanocomposite was developed by reinforcing the (Al + 10 V% Al2O3) with different weight percent (0.25%, 0.5%, 1%) of GO to obtain the optimum composition with improved mechanical/thermal properties. Results revealed that the Al\10 V% Al2O3\0.25 wt.% GO hybrid nanocomposite showed the highest improvement of about 13% in hardness and 34% in compressive strength as compared to the Al\10V% Al2O3 composite. Moreover, the hybrid nanocomposite Al\10 V% Al2O3\0.25 wt.% GO also displayed the lowest thermal expansion.

“…[17,20,21] Holographic metasurfaces (HMSs) offer unique advantages in optical imaging applications, including multi-color and three-dimensional displays, [22] virtual reality, [23] augmented reality, [24] and multi-information encoding and display. [25,26] These advantages stem from their ability to manipulate the properties of light, such as phase, [27] amplitude, [28] and polarization. [29] The precise wavefront control is enabled by arranging the meta-atoms in subwavelength scale arrays to generate intricate interference patterns, which form the target holographic images over a wide range of wavelengths, from visible to ultraviolet.…”

Optical curvature sensors find regular use in deformation analysis, typically requiring pre‐calibration and post‐processing of the gathered data. In this work, a self‐calibrated curvature sensor based on flexible holographic metasurfaces operating in the visible range is presented. In contrast to existing solutions, the sensor can be fabricated independently from the target objects and provides an immediate readout of their curvature. The sensor consists of distinct patterned areas that create images of a reference scale and of a position indicator, which shift with respect to each other, as the metasurface is deformed. The results of this sensor are validated with an external calibration and critically discuss the types of deformations that the sensor can detect. This feature makes the sensor particularly attractive for applications where real‐time curvature monitoring is essential, such as in robotics, biomechanics, and structural health monitoring.

“…However, enhancing the strength of metal matrix composites by introducing graphene is often at the expense of their plasticity, and its inverse relationship of strength and toughening limits the further development and application of graphene/metal matrix composites, which is essential. The fundamental reason is that during the deformation of the material, the stress concentration at the interface is prone to crack formation, and the crack expansion cannot be effectively hindered in the subsequent deformation [ 20 ]. Numerous studies [ 21 , 22 ] have shown that optimizing the toughness of composites by adjusting the configuration and distribution of graphene is an effective way.…”

Graphene has become an ideal reinforcement for reinforced metal matrix composites due to its excellent mechanical properties. However, the theory of graphene reinforcement in graphene/aluminum matrix composites is not yet well developed. In this paper, the effect of different temperatures on the mechanical properties of the metal matrix is investigated using a classical molecular dynamics approach, and the effects of the configuration and distribution of graphene in the metal matrix on the mechanical properties of the composites are also described in detail. It is shown that in the case of a monolayer graphene-reinforced aluminum matrix, the simulated stretching process does not break the graphene as the strain increases, but rather, the graphene and the aluminum matrix have a shearing behavior, and thus, the graphene “pulls out" from the aluminum matrix. In the parallel stretching direction, the tensile stress tends to increase with the increase of the graphene area ratio. In the vertical stretching direction, the tensile stress tends to decrease as the percentage of graphene area increases. In the parallel stretching direction, the tensile stress of the system tends to decrease as the angle between graphene and the stretching direction increases. It is important to investigate the effect of a different graphene distribution in the aluminum matrix on the mechanical properties of the composites for the design of high-strength graphene/metal matrix composites.
