This book was released on 2008 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal chalcogenides possess a wide range of interesting chemical and physical properties, including low-temperature superconductivity, semiconductivity, ionic conductivity, intercalation, and optical properties. To expand chalcogenides beyond their traditional applications, it is desirable to generate novel chalcogenide materials with multifunctionality for uses in the areas of catalysis, separation, ion exchange, and gas storage by modifying the framework architectures and tuning the chemical components. The primary focus of my Ph. D. study is to design and synthesize chalcogenide materials with new structures and interesting multifunctional properties. The large variety of chemical compositions and structures make it possible to tune the properties, such as band gap, luminescence, pore size, surface area, and thermal stability. Most of the synthesis has been carried out using solvothermal reactions refs in pyrex tube or teflon lined autoclaves. Novel three-dimensional (3D) microporous chalcogenides constructed on building units [M-Sn-Q]n- (M=Zn, Cd, Mn; Q=S, Se) have been obtained. Their structures have been characterized by both single crystal and powder X-ray diffraction methods. Optical diffuse reflectance experiments have indicated that these compounds are semiconductors with intermediate band gaps between 1.5~2.9eV. The successful doping/substitution of 5%~20% Mn and Se in the [Zn-Sn-S]n- structure allows systematic tuning of the band gap and optical properties of this semiconductor compound. All compounds show a high thermal stability over 400°C. Our studies also show that the guest molecules and cations residing in the open frameworks are exchangeable. Another novel two dimentional ion sulfide [Fe(en)3]·[Fe16S20]·en compound was synthesized as well. UV-Vis reflectance spectroscopy showed a very low absorption coefficient and small band gap ~0.5eV. Doping/substitution experiments with Co and Mn replacing Fe were carried out and the properties will be discussed. In summary, this work has provided examples of rational synthesis and property tuning of new functional materials with new structure types, and demonstrated structure-property correlation in metal chalcogenide based compounds. It has provided useful information for the future developments of material synthesis with desired multifunctionality.

Available in PDF, EPUB and Kindle. Book excerpt: The technology involved in lubrication by nanoparticles is a rapidly developing scientific area and one that has been watched with interest for the past ten years. Nanolubrication offers a solution to many problems associated with traditional lubricants that contain sulphur and phosphorus; and though for some time the production of nanoparticles was restricted by the technologies available, today synthesis methods have been improved to such a level that it is possible to produce large quantities relatively cheaply and efficiently. Nanolubricants develops a new concept of lubrication, based on these nanoparticles, and along with the authors’ own research it synthesises the information available on the topic of nanolubrication from existing literature and presents it in a concise form. Describes the many advantages and potential applications of nanotechnology in the tribological field. Offers a full review of the state-of-the-art as well as much original research that is yet unpublished. Includes sections on boundary lubrication by colloïdal systems, nanolubricants made of metal dichalcogenides, carbon-based nanolubricants, overbased detergent salts, nanolubricants made of metals and boron-based solid nanolubricants and lubrication additives. Authored by highly regarded experts in the field with contributions from leading international academics. Nanolubricants will appeal to postgraduate students, academics and researchers in mechanical engineering, chemical engineering and materials science. It should also be of interest to practising engineers with petroleum companies and mechanical manufacturers.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current climate crisis is a great concern to humankind due to the devastating effects of the consistent rise of anthropogenic greenhouse gases. A viable alternative to reducing greenhouse gas emissions is the development of solar harvesting technologies. The need to develop new semiconductor materials with more capacity to absorb light and convert it into electricity is rapidly growing. A promising class of materials for this purpose are copper-based ternary chalcogenides such as CuCrS2, CuSb1-xBixS2, and Cu3VS4.The synthesis and characterization of copper-based ternary chalcogenides nanocrystals (NCs) have gained popularity in the scientific community due to their novel, physical, chemical, optical, electronic, magnetic, and mechanical properties. NCs can be precursors to the next-generation nanoparticle-based thin film solar cells. This generation of thin film solar cells is advantageous in terms of the compounding benefits. Materials in the forms of NCs offer size, and morphology-dependent properties, high absorption coefficients, and tunable bandgaps. Nanoparticle-based thin film solar cells use very thin layers of material, lowering their production cost while making the systems flexible, more efficient, and compatible with new and existing infrastructure.This dissertation addresses several challenging issues and realizes the successful fabrication of novel CuCrS2, CuSb1-xBixS2 (x=1, 0.18), and Cu3VS4 NCs-based thin films. These systems were synthesized using two different thermal decomposition methods: heat-up (HU) and hot-injection (HI). This dissertation presents a detailed study involving the synthesis and characterization of the above-mentioned semiconductors by applying the developed nano-to-thin film approach. Their optical and electrical properties were explored, and their respective optical bandgaps were determined using UV-vis and electron energy loss spectroscopy (EELS). The ability of the fabricated thin films to generate a photocurrent under sunlight irradiation was explored, reporting their responsivities and current conversion efficiencies.
