Dimensional Nanomaterials examines synthesis methods—both bottom-up and top-down—alongside characterization techniques and applications. The text covers synthesis approaches, safety, toxicity, and regulatory aspects receiving thorough attention, promoting responsible nanomaterials development. Content explores zero-dimensional quantum dots, one-dimensional nanowires and nanotubes, two-dimensional graphene and transition metal dichalcogenides, and three-dimensional nanostructures systematically. Readers examine fabrication techniques including chemical vapor deposition, sol-gel methods, and self-assembly processes. Key topics include size-dependent properties, quantum confinement effects, surface phenomena, and interface engineering. The text addresses characterization methods including electron microscopy, atomic force microscopy, spectroscopy, and diffraction techniques. Through comprehensive coverage of dimensional nanomaterials, the material develops understanding of structure-property relationships at nanoscale. Applications span electronics, photonics, energy storage, catalysis, biomedicine, and environmental remediation. This essential resource serves materials scientists, nanotechnology researchers, and engineers seeking advanced understanding of dimensional nanomaterials. The book balances synthesis methodologies with practical applications and safety considerations for comprehensive perspective on emerging nanomaterials.
