    Impact of Graphene Oxide on the Mechanical Properties of Portland Cement Composites
    (Springer, Singapore, 2025) Mohd. Sufian Abbasi, Noureen Ansari, Mohd. Azhar, Mohd. Samiullah, Neda Tabassum, Syed Aqeel Ahmad, Qazi Inamur Rahman
    This chapter investigates the transformative influence of Graphene Oxide (GO) on the strength properties of Portland Cement composites, delving into the realm of nanomaterial reinforcement for advanced construction materials. Focusing on the enhancement of compressive, flexural, and tensile strength, Impact and Fracture Toughness, the study explores the multifaceted interactions between GO and the cementitious matrix. Beginning with an overview of the essential characteristics of GO, the chapter provides insights into synthesis and incorporation techniques for GO in Portland Cement composites, setting the stage for understanding its potential as a reinforcement agent in Portland Cement composites. The findings from this chapter contribute to the evolving landscape of nanomaterial-modified cementitious systems, offering a deeper understanding of how GO can be harnessed to propel the strength performance of Portland Cement composites. As the construction industry seeks sustainable and high-performance solutions, this chapter provides a valuable resource for scholars, engineers, and practitioners aiming to advance the frontier of modern construction materials.

    Mitigation of Metal Toxicity in Plants Using Silver Nanoparticles
    (Springer Nature, 2024) Kulsum Hashmi, Tahmeena Khan, Saman Raza, Seema Joshi
    Certain metals like Ca, Mg, Cu, and Fe are essential for plant growth while several others, like As, Cd, and Pb are not; the presence of these metals in soilc above a certain threshold concentration is toxic to plants. They lead to several cellular and structural changes in the plants by increasing oxidative stress and modifications in certain metabolic pathways. The plant in turn responds to this stress by several methods like increasing the production of antioxidants and other enzymes. Metal toxicity hampers water uptake, nutrient assimilation and consequently plant growth. As a result, there is a decrease in plant productivity as well as quality, leading to financial loss for the farmers and health problems for the consumers. Several methods are used for the remediation of this toxicity in the soil and the plants, including leaching, use of chelators, phytoremediation, etc. However, most of these techniques have drawbacks like being expensive, hazardous to the environment, unsuitable for varied use and not being target specific. In recent years, nanotechnology has emerged as a safe and effective tool with many desirable outcomes. Its use is being explored in agriculture as well, with nanoparticles being employed in soil fertilizers, disease management and removal of toxins. This chapter describes in detail, the effect of metal toxicity in plants and the use of nanoparticles, for its remediation. AgNPs are of particular interest here, owing to their beneficial effects on plants which have been widely investigated.
