“…In a study by Chengini et al [38], they developed a bioinspired composite based on carbon fiber and cellulose for use in aircraft components. They found that the composite exhibited excellent mechanical properties and could withstand high temperatures, making it a promising material for aerospace applications [39]. In the field of engineering, bioinspired composites have the potential to improve the performance of structures and machinery.…”

Bioinspired composites have become an increasingly popular area of research in materials science, as they offer a promising approach to developing high-performance materials. By drawing inspiration from the structures and properties of natural materials, researchers can design composites with enhanced mechanical, thermal, and other properties. This review article discusses the lessons that can be learned from nature for materials design and performance, with a focus on the structures and properties of biological materials such as bone, spider silk, and nacre. We explore the key mechanisms that give these materials their unique properties, including hierarchical structures, nanoscale building blocks, and interfacial interactions. By understanding these mechanisms, researchers can develop new materials with improved strength, toughness, and other desirable properties. We also discuss the potential applications of bioinspired composites in fields such as aerospace, engineering, and biomedical science. Overall, this review highlights the importance of nature as a source of inspiration for materials design and provides insights into the development of high-performance composites.

“…In addition to its applications in materials science, the sol-gel method has also found use in the fabrication of thin films and coatings, as well as in the production of catalysts and sensors. After synthesis, the product is purified to remove any impurities or by-products that may have formed during the reaction [22,23]. DNA analysis is a powerful tool for identifying the source of raw materials, particularly in cases where visual inspection or traditional analytical methods are insufficient.…”

Modern material processing methods are revolutionizing the biomedical and health care sectors while offering previously unexplored possibilities for the development of cutting-edge biomaterials. The development of materials with distinctive optical, mechanical, and biological characteristics can be made feasible by innovative techniques such as chemical vapor deposition (CVD) & sol-gel processing. These developments have a wide range of applications such as biological sensing technologies, drugs delivery systems, as well as tissue engineering. The present investigation examines the application of chemical vapor deposition (CVD) and sol-gel techniques for producing biomaterials customized for certain biomedical applications. The development of nanomaterials, such as mesoporous silica nanoparticles, biologically active glass nanoparticles, and graphene-based coatings, will be discussed in particular. These materials were chosen for their adaptability and demonstrate promise in a number of medical domains, including the advancement of diagnostic imaging techniques, medication delivery systems, and wound healing processes.

“…The factor of safety is the most straightforward and extensively utilized strategy in handling variability and uncertainty in engineering design (Nigro and Arch, 2023;Moreland, 2009). The application of safety considerations to ensure that a building can fulfill its intended function reduces the chance of failure to an acceptable level (Amitrano et al, 2023;Sarma et al, 2020). Both materials have the same safety factor of 15, which is relatively high and considerably above one, indicating that neither material will fail under the current conditions.…”

Injury to the brachial plexus prevents the arm, wrist, and hand from communicating with the spinal cord in whole or in part. The 'patient's upper arm limb appears to be completely incapable of performing any type of independent movement. The aim of this project is to design and develop a customized adaptive assistive device for patients with brachial plexus injury and to fabricate the prototype using 3D printing technology. The development of the device involved adapting the mechanical engineering design process, including conceptual design and finite element analysis, to predict the performance of the design and to select the best printing materials. The patient's left arm was 3D scanned to create a customized part that perfectly fit the patient. The 3D model of the prototype was developed using Autodesk Fusion 360 and Autodesk TinkerCAD. Two different materials, namely Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS), were considered in the computational analysis. Results show that the maximum von Misses stress of PLA is observed at 2.464 MPa, slightly higher than the ABS material (2.451 MPa), indicating a greater stress tolerance imposed on the material's strength. However, PLA has a smaller maximum displacement than ABS, at 0.019 mm and 0.030 mm, respectively. The PLA material was chosen for 3D printing based on several considerations, including mechanical qualities, cost, printing time, durability, and data evaluation. The adaptive device for brachial plexus injury was successfully delivered to the patient and demonstrated the capability to assist in arm movement.
