Book Description
We identified that the growth parameters are vital to control the crystallinity, morphology and the defect levels in the synthesized ZnO nanowires. SEM, XRD, TEM, HRTEM analysis show that the nanostructures are highly crystalline and are vertically oriented. We also report the in-situ growth of PbS nanoparticles without linker on the surface of well -oriented ZnO NWs by (SILAR) technique. The PbS Nanoparticles are packed tightly on the surface of the ZnO Nanowires with different sizes and densities, without insulating nature organic ligands, which might affect both the electronic structure at the interface and the electron - transfer rate. The SEM, TEM, HRTEM, PL and XRD analysis, confirm the attachment of the spherical shape polycrystalline PbS nanoparticles. We propose at the end of the thesis the p-PbS /n-ZnO hetero-junction with its future applications in solar cells.

Book Description
Nanostructured Zinc Oxide covers the various routes for the synthesis of different types of nanostructured zinc oxide including; 1D (nanorods, nanowires etc.), 2D and 3D (nanosheets, nanoparticles, nanospheres etc.). This comprehensive overview provides readers with a clear understanding of the various parameters controlling morphologies. The book also reviews key properties of ZnO including optical, electronic, thermal, piezoelectric and surface properties and techniques in order to tailor key properties. There is a large emphasis in the book on ZnO nanostructures and their role in optoelectronics. ZnO is very interesting and widely investigated material for a number of applications. This book presents up-to-date information about the ZnO nanostructures-based applications such as gas sensing, pH sensing, photocatalysis, antibacterial activity, drug delivery, and electrodes for optoelectronics. Reviews methods to synthesize, tailor, and characterize 1D, 2D, and 3D zinc oxide nanostructured materials Discusses key properties of zinc oxide nanostructured materials including optical, electronic, thermal, piezoelectric, and surface properties Addresses most relevant zinc oxide applications in optoelectronics such as light-emitting diodes, solar cells, and sensors

Book Description
Zinc-Based Nanostructures for Environmental and Agricultural Applications shows how zinc nanostructures are being used in agriculture, food and the environment. The book has been divided into two parts: Part I deals with the synthesis and characterization of zinc-based nanostructures such as biogenic, plant, microbial, and actinobacteria mediated synthesis of zinc nanoparticles, Part II is focused on agri-food applications such as antibacterial, antifungal, antimicrobial, plant disease management, controlling post-harvest diseases, pesticide sensing and degradations, plant promotions, ZnO nanostructure for food packaging application, safe animal food and feed supplement, elimination of mycotoxins, and veterinary applications. Part III reviews technological developments in environmental applications such as risks and benefits for aquatic organisms and the marine environment, antiseptic activity and toxicity mechanisms, wastewater treatment, and zinc oxide-based nanomaterials for photocatalytic degradation of environmental and agricultural pollutants. The book discusses various aspects, including the application of zinc-based nanostructures to enhance plant health and growth, the effect on soil microbial activity, antimicrobial mechanism, phytotoxicity and accumulation in plants, the possible impact of zinc-based nanostructures in the agricultural sector as nanofertilizer, enhancing crop productivity, and other possible antimicrobial mechanisms of ZnO nanomaterials. Explores the impact of a large variety of zinc-based nanostructures on agri-food and environment sectors Outlines how the properties of zinc-based nanostructures mean they are particularly efficient in environmental and agricultural application areas Assesses the major challenges of synthesizing and processing zinc-based nanostructured materials

Book Description
This book presents a review of recent advances in ZnO-based nanomaterials and devices. ZnO as a nanomaterial has gained substantial interest in the research area of wide bandgap semiconductors and is considered to be one of the major candidates for electronic and photonic applications. ZnO has distinguished and interesting electrical and optical properties and is considered to be a potential material in optoelectronic applications such as solar cells, surface acoustic wave devices, and UV emitters. ZnO's unique properties have attracted several researchers to study its electrical and optical properties. As a nanostructured material, ZnO exhibits many advantages for nanodevices. Moreover, it has the ability to absorb the UV radiation.

Book Description
Zinc Oxide nanostructures are important for many applications, specifically for developing novel catalysts and sensors which our research group has been working on. The objectives of this thesis are: (1) synthesis and characterization of complex ZnO nanostructures; (2) development of synthesis protocols for high-yield and reliable synthesis of nanostructures. In this thesis, chapter 1 introduces the background of nanoscience and nanotechnology, with a focus on nanomaterials. In chapter 2, the fundamental knowledge of ZnO and relevant characterization techniques are introduced, specifically the crystallography of ZnO wurtzite structure and the scanning (transmission) electron microscopy. Several goals have been achieved and they are reported in chapter 3 and 4. First, the nano-pyramid decorated microwires were fabricated. A growth mechanism for those complex nanostructures was proposed. Second, surface modification such as grooved surfaces of ZnO nanostructures has been realized. Grooved nanowires, microbelts, and micrometer-scale tetra-pods are discussed. Third, the effects of oxygen partial pressure on the growth of ZnO have been investigated. All the ZnO nanostructures reported in this thesis were synthesized by a physical vapor deposition method. The field-emission scanning electron microscope was used to examine the morphologies of the synthesized nanostructures. Aberration-corrected scanning transmission electron microscopy provided information on the fabricated nanostructures.
