“…Among them, multifunctional nanocomposites integrating the advantages of two or more base materials have attracted great attention owing to their synergistic effects and enhanced properties when compared to the individual base counterparts [ 9 , 10 ]. The nanocomposite encompasses a diverse category of materials, ranging from 3D and 2D composites to 1D NWs and 0D core shells [ 11–13 ]. The properties of nanocomposites are influenced not only by the used individual components but also by their morphology and interface characteristics.…”

Bacteria-infected wounds healing has been greatly hindered by antibiotic resistance and persistent inflammation. It is crucial to develop multifunctional nanocomposites that possess effective antibacterial properties and can simultaneously accelerate the wound healing process to overcome the above challenges. Herein, we prepared a yolk-shell structured Ag nanowires (NWs)@amorphous hollow ZIF-67 by etching ZIF-67 onto the Ag NWs for infected wound healing for the first time. The etched hollow structure of amorphous ZIF-67 in the nanocomposite makes it a promising platform for loading healing-promoting drugs. We extensively studied the antibacterial and healing-promoting properties of the curcumin (CCM)-loaded nanocomposite (Ag NWs@C-HZ67). Ag NWs, being noble metal materials with plasmonic effects, can absorb a broad range of natural light and convert it to thermal energy. This photothermal conversion further improves the release of antibacterial components and wound healing drugs when exposed to light. During the healing process of an infected wound, Ag and Co ions were released from Ag NWs@C-HZ67 upon direct contact with the wound exudate and under the influence of light irradiation. Simultaneously, the loaded CCM leaked out to repair the infected wound. The minimum inhibitory concentrations of the Ag NWs@C-HZ67 groups against E. coli and S. aureus bacteria decreased to 3 and 3 μg mL−1 when exposed to white light. Furthermore, an in vivo assessment of infected wound healing demonstrated that combining Ag NWs@C-HZ67 with light significantly accelerated the wound healing process, achieving 70% healing by the 6th day and almost complete healing by the 8th day. This advanced nanocomposite, consisting of components that possess antibacterial and growth-promoting properties, offers a safe, effective, and clinically-translatable solution for accelerating the healing process of infected wounds.

“…Nanocomposites generally have improved mechanical strength, stiffness, and toughness compared to the matrix material due to strong interfaces between the filler and matrix. [5] These properties are enhanced by the dispersion method of the filler within the matrix, the bonding type between the filler and matrix, as well as the size and shape of the filler particles. [6,7] The high homogeneity and strong interfaces between the filler and matrix lead to better load transfer and resistance to crack propagation, resulting in improved mechanical properties.…”

The properties of materials used in building are enhanced by adding nanoparticles for improve energy efficiency. The objective of this study is to offer both numerical and analytical modeling methods of the thermal conductivity and mechanical property of composite materials. Various mineral charges were employed to reinforce the organic matrices of saturated polyester resin (UPR) with calcium carbonate (CaCo3) and expanded perlite particles. The study employs the finite‐element software COMSOL to conduct a numerical investigation of thermal transport in an elementary cell. The purpose is to ascertain the thermal conductivity of composites and examine the impact of contact resistance and the volume fraction of nanoparticles on the effective thermal conductivity. The results indicate that the numerical model proposed is consistent with the Hashin‐Shtrikman analytical model and experimental measurements. In another hand, the mechanical property is computed based on Mori‐tanaka analytical model of homogenization and finite element method by Digimat‐MF/FE, which gives enhanced elastic behavior of composite in function of volume fraction of nanoparticles, with high Young modulus and low Poisson ratio. The results indicate the performance of nanoparticles in improving thermomechanical behavior of building materials, and also in other applications.

“…Recently, a significant amount of research effort has been undertaken in the field of MMCs to adopt the advantages offered by carbon nanomaterials [1]. With their distinctive electrical, mechanical, and thermal characteristics, carbon nanotubes and graphene nanosheets are desirable reinforcement materials for making lightweight, highly durable, and highperforming MMCs for applications in functional and structural engineering [1,2]. Due to their extraordinary properties, carbon nanomaterials [1] as well as other nanoparticles such as boron nitride nanotubes, boron nitride nanosheets, MXene, and metal dichalcogenides [2] have become useful nanoscale fillers for creating metal matrix nanocomposites (MMNCs), which are being used to circumvent the performance restrictions of conventional MMCs.…”

Improving the damping capacity of metal matrix composites is crucial, especially for applications in the aerospace industry where reliable performance against vibrations and shocks is mandatory. The main objective of the present study is the numerical prediction of the damping behavior of alpha titanium matrix nanocomposites reinforced with hollow carbon nano-onions at various volume fractions. According to the proposed numerical scheme, a structural transient analysis is implemented using the implicit finite element method (FEM). The metal matrix nanocomposites are modeled via the utilization of appropriate representative volume elements. To estimate the mechanical and damping behavior of the nanocomposite representative volume elements, axial sinusoidally time-varying loads are applied to them. The damping capacity of the metal matrix nanocomposites is then estimated by the arisen loss factor, or equivalently the tan delta, which is computed by the time delay between the input stress and output strain. The analysis shows that the loss factor of alpha titanium may be improved up to 60% at 100 Hz by adding 5 wt% carbon nano-onions. The numerical outcome regarding the dynamic properties of the carbon nano-onions/alpha titanium nanocomposites is used in a second-level analysis to numerically predict their damping performance when they are additionally reinforced with unidirectional carbon fibers, using corresponding representative volume elements and time-varying loadings along the effective direction. Good agreement between the proposed computational and other experimental predictions are observed regarding the stiffness behavior of the investigated metal matrix nanocomposites with respect to the mass fraction of the carbon-onion nanofillers in the titanium matrix.
