GO/rGO as Strengthening Nanofiller in Carbon Fiber/Epoxy Resin Composite Materials | Chapter 2 | Chemical and Materials Sciences: Research Findings Vol. 1

 Epoxy polymer composites with carbon fiber as reinforcement have an extensive range of applications in many industrial fields as: wind turbines, construction, aeronautics and aerospace due to their favorable strength-to-weight and stiffness-to-weight ratios, as well as their high thermal stability and excellent corrosion resistance. Interfacial interactions between matrix and composite reinforcement greatly influence the material's final properties. Carbon Fibers are characterized as having low interactions with resins when forming a composite material. In the present study, 0.3 wt% of GO/rGO were incorporated in three epoxy resin/carbon fiber systems as reinforcing fillers, trying to profit from the chemical affinity between aromatics structures of GO/rGO and polar interactions with epoxy resin. GO/rGO was characterized by XPS, TGA was performed on carbon fiber, epoxy resins and composites obtained and SEM was utilized to observe composite samples in detail once mechanical tests were conducted. Composites experienced noticeable enhancements by employing Bisphenol Epoxy (BP) cured with methyl cyclohexane-1,2-dicarboxylic anhydride (MCHDA) as matrix and carbon fiber of 300 g/cm2 as reinforcement; Young's modulus, rupture stress and elongation to failure increased almost twofold compared to non-modified composites by adding GO in the system and even superior boosts can be appreciated with rGO, which additionally improves the flexural stress from 14.6 to 30.1 GPa. Flexural behavior is affected by the presence of GO or rGO, but due to the 3D configuration achieved it is difficult to observe a clear influence of the chemical groups in filler particles.

Eucalyptus Trees as Sources of Medically Related Products: A Brief Overview | Chapter 13 | New Visions in Biological Science Vol. 5

 Eucalyptus species are grown for a range of goods all around the world. We recently discussed their overall significance for energy products as well as their potential as medicinal products, and we are now providing an update on their prospects for specific medically linked products. We also look at some of the most promising strategies for turning potential cellulosic leftovers into high-value commodities. Many items that are currently made with petrochemicals can be made with Eucalyptus biomass. Larvicides, repellants, antibacterial, antifungal, and anticancer agents, biofilm inhibitors, nanoparticles, carbon fibres and derived items (e.g., surgical implants), graphene-based uses, and numerous energy products are among the many applications for eucalyptus bioproducts, which are classified as naturally occurring, generated by biochemical processes, or the result of thermochemical processes.
