“…XRD observed no impurities peaks and in proper plan concerning copper as (111), (200), and (220). The XRD pattern of synthesis particles' findings reinforces the general belief that there is no change in the shift in the crystal structure of Cu; the results of this method are in agreement with JCPDS card no 98−005−3247 [29]. The diameter of the copper particles was less than 20 µm, and they were spherical in shape.…”

Particle synthesis has seen significant advances in current trends. However, the synthesis of metal particles without oxidation is a challenge for researchers. The current study presents a straightforward, convenient, and convincing approach for manufacturing copper (Cu) particles free of surface oxide. The die-sink Electrical Discharge Machine (EDM) of copper alloys with oleic acid resulted in the formation of Cu particles with diameters between 10 to 20 µm. X-ray diffraction (XRD) was used for particle examination after cleaning and sonication with distilled water. Cu particles with oleic acid coating retained a Cu phase without oxidation after synthesis. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to determine the size and morphology of generated particles. Fourier transforms infrared (FT-IR) analysis revealed the oleic acid-coated Cu surface bonded with an oxygen atom. Also, the agglomeration and change of size involving Cu particles with increasing voltages in the pulse supply in EDM were reported.

“…In Figure 12 is also shown a comparative between representative 3D topographies of the surface for the samples C3M (non‐reinforced) and C3MR. It is worth mentioning that such improvements of rugosity accompanied by an adequate mechanical response are properties highly desired for materials to be harnessed in different sectors such as aeronautics and automotive industries 1,52,53 …”

The development of innovative engineered epoxy composites aiming to manufacture cost-efficient materials with reduced weight and enhanced physical properties remains as a current industrial challenge. In this work we report an original procedure for manufacturing glass-fiber epoxy reinforced nanocomposites (GFECs) by employing electrospun fiber-mats as a reinforcing phase. These fibers have been produced from polyacrylonitrile and multiwalled carbon nanotubes solutions. Optimal protocols are designed by combining Taguchi method with the morphological, structural and mechanical properties obtained by scanning electron microscopy, profilometry and tensile tests. It is demonstrated that GFECs fabricated using GF800 glass fiber show an improvement/enhancement of the mechanical properties with a fracture strain up to 500 MPa (around 20% higher than the nonreinforced epoxy composite counterpart). It is also shown that GFECs fabricated using GF3M glass fiber exhibited a reduction of the roughness up to 56%, which corresponds with a roughness improvement from N8 to N7 following the guidelines provided by the ISO 1302. These results suggest that this type of nanocomposites would be suitable to be used in the aeronautics and automotive industries.

“…Metal-based nanomaterials with different compositions, morphologies, sizes, and aggregation states, especially 2D materials, can be prepared by controlling components and processing methods, which exhibit various antibacterial activities. [50] Generally, metal-based particles are positively charged due to the dissolution of metal ions, and they are strongly attracted to the bacterial cell wall with opposite charges. [51] This causes physical environmental changes in which bacteria live.…”

The global pandemic and excessive use of antibiotics have raised concerns about environmental health, and efforts are being made to develop alternative bactericidal agents for disinfection. Metal‐based nanomaterials and their derivatives have emerged as promising candidates for antibacterial agents due to their broad‐spectrum antibacterial activity, environmental friendliness, and excellent biocompatibility. However, the reported antibacterial mechanisms of these materials are complex and lack a comprehensive understanding from a coherent perspective. To address this issue, a new perspective is proposed in this review to demonstrate the toxic mechanisms and antibacterial activities of metal‐based nanomaterials in terms of energy conversion and electron transfer. First, the antimicrobial mechanisms of different metal‐based nanomaterials are discussed, and advanced research progresses are summarized. Then, the biological intelligence applications of these materials, such as biomedical implants, stimuli‐responsive electronic devices, and biological monitoring, are concluded based on trappable electrical signals from electron transfer. Finally, current improvement strategies, future challenges, and possible resolutions are outlined to provide new insights into understanding the antimicrobial behaviors of metal‐based materials and offer valuable inspiration and instructional suggestions for building future intelligent environmental health.
