Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials via Single-Source Precursors: Synthesis, Processing and Applications presents recent results and overviews of synthesis, processing, characterization and applications of advanced materials for energy, electronics, biomedicine, sensors and aerospace. A variety of processing methods (vapor, liquid and solid-state) are covered, along with materials, including metals, oxides, semiconductor, sulfides, selenides, nitrides, and carbon-based materials. Production of quantum dots, nanoparticles, thin films and composites are described by a collection of international experts. Given the ability to customize the phase, morphology, and properties of target materials, this "rational approach to synthesis and processing is a disruptive technology for electronic, energy, structural and biomedical (nano)materials and devices. The use of single-source chemical precursors for materials processing technology allows for intimate elemental mixing and hence production of complex materials at temperatures well below traditional physical methods and those involving direct combination of elements. The use of lower temperatures enables thin-film deposition on lightweight polymer substrates and reduces damage to complex devices structures such as used in power, electronics and sensors. - Discusses new approaches to synthesis or single-source precursors (SSPs) and the concept of rational design of materials - Includes materials processing of SSPs in the design of new materials and novel devices - Provides comprehensive coverage of the subject (materials science and chemistry) as related to SSPs and the range of potential applications

This book was released on 2018-03-07 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2018 in the subject Chemistry - Anorganic Chemistry, grade: 10, , language: English, abstract: Nanoscience is the study of phenomena exhibited by materials at atomic, molecular and macromolecular levels, of dimensions ranging from a few nanometres to less than a hundred nanometres. In chemistry, this size range has been associated with colloids, micelles, polymer molecules and similar structures. In physical and electrical engineering, nanoscience is often associated with quantum behaviour, and electron behaviour in nanoscale structures. The area of research in the field of nanotechnology is as diverse as physics, chemistry, material science, microbiology, biochemistry and also molecular biology. The interface of nanotechnology in combination with biotechnology and biomedical engineering has emerged with the use of nanoscale structures in diagnosis, gene sequencing, and drug delivery. Nanoparticles have attracted great interest in recent years because of their unique chemical and physical properties, which are different from those of either the bulk materials or single atoms. Nanostructure materials have potential applications in ceramics, optoelectronics and catalysis. Research on the synthesis of nanomaterials using metal complexes as precursors have been less reported. Application of metal complexes as precursors may be helpful to control the physical properties of metal nanoparticles. In the last few years, researchers have characterized the tunable properties by altering the nanostructure size, shape, and chemical composition and have developed reproducible strategies to make nanostructures of desired properties. It has been already proved that by controlling the size of the particle and manipulating surface structures of the semiconductor materials, the electronic, magnetic, mechanical, and chemical properties can be modified to suit a wide range of device application in many fields. The present book deals with the synthesis of Schiff base complexes of Cd(II), Zn(II) and Hg(II) with different sulphur containing ligand and preparation of metal sulphide nanoparticle by the thermal decomposition of complex precursor. During this academic journey four new sulphur containing ligands and their thirty complexes were synthesized. These ligands and complexes were characterized by spectroscopic methods like UV-Vis, FT-IR, 1H-NMR, 13C-NMR, 2D-NMR, FAB-MS / ESI-Ms spectra.

This book was released on 2005-09-29 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Material synthesis by the transformation of organometallic compounds (precursors) by vapor deposition techniques such as chemical vapor deposition (CVD) and atomic layer deposition (ALD) has been in the forefront of modern day research and development of new materials. There exists a need for new routes for designing and synthesizing new precursors as well as the application of established molecular precursors to derive tuneable materials for technological demands. With regard to the precursor chemistry, a most detailed understanding of the mechanistic complexity of materials formation from molecular precursors is very important for further development of new processes and advanced materials. To emphasize and stimulate research in these areas, this volume comprises a selection of case studies covering various key-aspects of the interplay of precursor chemistry with the process conditions of materials formation, particularly looking at the similarities and differences of CVD, ALD and nanoparticle synthesis, e.g. colloid chemistry, involving tailored molecular precursors.

This book was released on 2010 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the synthesis of novel nanoparticles that are interesting for catalytic applications. The decomposition of RhCp(C2H4)2 and Rh(hfacac)(CO)2 were investigated, and the complex RhCp(C2H4)2 was successfully shown to decompose to rhodium nanoparticles. Analysis of the decomposition chemistry was used to control nanoparticle seed formation and growth. New stabilizer ligands, both polymeric and molecular, were attempted for the synthesis of rhodium nanoparticles. Polymeric stabilizers were screened as replacements for the widely used polyvinylpyrollidone (PVP) surfactant, however none afforded the high degree of control exhibited by PVP. However, molecular stabilizers were screened and small, monodisperse rhodium nanoparticles were synthesized with the stabilizer octadecylphosphonic acid, with a size and size dispersity of 1.92 +/-0.16 nm. A concurrent hydrogenation catalytic process was also utilized for the synthesis of small rhodium seed particles. In this nanoparticle synthesis, a rhodium precursor and a stabilizer were combined in the presence of an olefin and hydrogen, which aids in decomposition of the rhodium precursor to nanoparticles, and also catalytically converts the olefin to a saturated compound. The rate of hydrogen uptake was monitored and fit to a two-step autocatalytic mechanism correlated to nanoparticle formation and growth. Two new rhodium complexes were synthesized that contained a stabilizer ligand, however the most successful attempt to produce small, monodisperse rhodium nanoparticles by this process was with the rhodium source [(COD)Rh(NCCH3)2]BF4, and the stabilizer (Bu4N)2HPO4 in the presence of an equivalent of Proton Sponge0. Rhodium nanoparticles synthesized by this process have a size and size distribution of 1.88 +/-0.27 nm. The presence of olefin and hydrogen pressure of 42 psi was found to be ideal for the stabilization of nanoparticles during their formation. Also, reactant concentrations and the rate of the cyclohexene consumption are crucial to yield nanoparticles with this excellent size dispersity. Growth reactions with these small rhodium nanoparticles have been successful the synthesis of larger nanoparticles under conditions involving alternate stabilizers. The small nanoparticles were then tested and found to be useful as seed particles in the synthesis of larger rhodium nanoparticles. For each procedure, a mixture of 1-hexadecylamine, adamantane carboxylic acid, and 1,2-hexadecanediol was used to stabilize the nanoparticles. The use of synthesized seed particles allowed for the formation of tetrahedral (average edge length: 4.77 +/- 0.72 nm) or icosahedral shaped particles, depending on reaction temperature. Subsequent characterization revealed that approximately half of the tetrahedrally shaped nanoparticles are in fact triangular flat rafts, where one corner of the tetrahedron appears to be "cut off." However, the use of in situ seeds resulted in the formation of multipod structures. The multipods are single crystals with 2-8 arms per multipod, that propagate both the (110) and (111) directions. The synthesis and characterization of mixed-metal oxide spinel nanoparticles was then attempted for water oxidation catalysis. Nanoparticles of the compositions MnFe2O4 and CoFe2O4 (5.7 nm and 6.1 nm respectively) were synthesized according to a literature procedure with the stabilizers oleic acid and oleylamine, however they were characterized by ICP-OES to have low M:Fe (M = Mn, Co) ratios of 1:5 and 1:4 respectively. Nanoparticles of NiFe2O4 (8.0 nm) were also synthesized by a similar approach, and had the expected Ni:Fe ratio of 1:2 by ICP-OES. Cubic nanoparticles of Co3O4 were also synthesized, and through a subsequent cation exchange reaction with this material, CuxCo3-xO4 and NixCo3-xO4 nanoparticles could be synthesized with varying degrees of copper or nickel incorporation. Linear scan voltammograms were conducted on anodes modified with these nanoparticle materials. For the mixed-metal ferrites, CoFe2O4 showed the lowest overpotentials in the water oxidation reaction in the range of 0-100 mA cm-2. Copper modified Co3O4 nanoparticles had a lower onset potential than Co3O4 and performed with lower overpotentials at low current densities (20 mA cm-2). The nickel modified Co3O4 nanoparticles were superior to the other MxCo3-xO4 materials at all current densities measured (0-100 mA cm-2).

This book was released on 2022-05-06 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doctoral Thesis / Dissertation from the year 2022 in the subject Chemistry - Materials Chemistry, , course: CHEMISTRY, language: English, abstract: This thesis reports the symthesis of five metal complexes, namely bis(piperidinylldithiocarbamato)nickel(II) (1), bis(tetrahydroquinolinyldithiocarbamato)nickel(II) (2), bis(N’-ethyl-N-piperazinyldithiocarbamato)nickel(II) (3), tris(morpholinodithiocarbamato)cobalt(III) (4) and tris(N’-ethyl-N-piperazinyldithiocarbamato)cobalt(III) (5). These heterocyclic dithiocarbamate complexes have been characterised using common techniques such as Fourier Transform Infrared spectroscopy, elemental analysis and nuclear magnetic resonance spectroscopy. Nuclear magnetic resonance spectroscopy measurements were not conducted for complexes, due to their paramagnetic behaviour which adversely interferes with the technique. Single-crystal X-ray diffraction was used instead, which aided in the accurate elucidation of novel chemical structures of the complexes. Three complexes were characterised using the technique; the chemical structures of the rest are already known in literature. Generally, dithiocarbamate complexes have been identified as compounds of technological importance, particularly as single-source molecular precursors for the fabrication of nanomaterials for widespread applications. However, interest has mainly been on alkyl derivatives. Thus, this thesis focuses on the use of heterocyclic dithiocarbamates complexes as single-source molecular precursors for the fabrication of the corresponding metal sulfide thin films and nanoparticles through thermal decomposition routes. Thermal decomposition of the complexes (1)-(5) produced Ni-S, Co-S and Ni-Co-S nanoparticles and thin films which exhibited interesting morphological and optoelectronic properties. The above-mentioned systems were particularly chosen for their increased interest in magnetism, as well as energy generation and storage applications. In this thesis, the nature of the complexes and other reaction parameters were demonstrated to have an influence on the particle size, morphology, and phase purity of the nanoparticles and thin films produced. These properties have a profound impact on the efficiency of the nanoparticles and thin films, towards specific applications.
