Chapter 4, "Vapor-Grown Carbon Fiber Synthesis, Properties, and Applications" discusses synthesis and properties of carbon fibers and vapor-grown carbon nanofibers as well as their mechanical, electrical, and thermal properties. In addition, several potential applications of fibers, such as in composites and

batteries, are also discussed. Carbon nanofibers and their composites can be utilized in numerous fields, including sensors, electrode materials, and electromagnetic shielding. Electrode materials and the realization of extraordinary structural designs to ensure large specific areas without sacrificing mechanical performances

Chapter 5, "Fiber composites made of low-dimensional carbon materials," provides an overview of the research on carbon nanotubes (CNTs), carbon fibers (CFs), and graphene-based fibers (GBFs) in composite materials. It also summarizes the main preparation methods, properties, and application fields of CNTs, CFs, and GBFs. Through various methods of modification, researchers continue to prepare CNT composite nanomaterials with excellent performance. Finally, the chapter examines existing problems and future development trends of carbon-based

Chapter 6, "Reinforce Fabricated Nano-Composite Matrixes for Modernization of S & T in New Millennium" is a brief review of certain recent advances in assembly and reconfiguration of polymeric nanostructure composites and highlights their role in computer simulation. In addition, it presents the fundamental principles of assembly science as well as provides critical design tools for assembly engineering of complex nanostructured materials. The chapter also discusses the advantages of

Chapter 7, "Composite nanofibers: recent progress in adsorptive removal and photocatalytic degradation of dyes," reviews the state of the art of a new generation of nanomaterials based on electrospun composite nanofibers for dye removal from wastewater. Natural polymers-based nanofibers, nanofibers with unique morphology, and carbon nanofibers are reviewed. The various nanostructures, adsorption capacity, advantages, and drawbacks are discussed along with mechanistic actions in the adsorption process and photocatalytic performance. The chapter covers multiple intriguing topics with in-depth discussion. This is a valuable reference for researchers who are working on nanomaterials and the

Chapter 8, "Nanosilica composite for greenhouse application," presents the results of experiments on silicon dioxide insulation materials mixed with low-density polyethylene (LDPE) at a different proportion to prevent the transmittance of IR domain and to allow the transmittance of UV–Vis domains. Several ratios of nanosilica particles are employed to fabricate LDPE composites using melt mixing and hot molding methods. The mechanical properties of nanocomposites such as tensile strength are evaluated and discussed. The advantages of using nanosilica in the nanocomposite materials are summarized and the use of these LDPE/silica nanocomposites to build a mini greenhouse is

are key factors in enhancing the performances of these materials.
