This book was released on 2012 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work will demonstrate the ability of a ZnO nanowire interphase to reinforce the interface of both aramid and carbon fiber composites. The interfacial shear strength of single fiber aramid composites is enhanced by 41% and single carbon fiber composite are improved by 110% with this process. Lamina scale testing on unidirectional carbon fiber composites demonstrates a 37% increase in shear strength and a 38% increase in shear modulus for the affected fibers. Given that ZnO nanowires are grown directly onto the underlying fiber, the interface between the nanowires and fiber will have low surface area and minimal interlocking, which implies that the chemical adhesion of the nanowires is strong. This work develops new functionalization procedures that directly control the interface chemistry to enhance the adhesion of the ZnO nanowires to the fiber. A critical contribution of this work, beyond the development of this new interfacial reinforcement material, is the identification of the mechanism controlling the strong adhesion which can be used to engineer other materials or achieve further advances.

This book was released on 2017-12-14 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book primarily focuses on methodologies to enable marine structures to resist high velocity impact loadings. It is based on invited talks presented at the recent India–USA workshop on “Recent Advances in Blast Mitigation Strategies in Civil and Marine Composite Structures” The book comprises content from top researchers from India and the USA and covers various aspects of the topic, including modeling and simulation, design aspects, experimentation and various challenges. These failure modes significantly reduce the structural integrity of the marine structures unless they are designed to resist such harsh loadings. Understanding the mechanics of these structures under harsh loadings is still an open area of research, and the behavior of these structures is not fully understood. The book highlights efforts to reduce the effects of blast loadings on marine composite structures. Intended for researchers/scientists and practicing engineers, the book focuses not only the design and analysis challenges of marine composite structures under such harsh loading conditions, but also provides new design guidelines.

Book Synopsis Fundamental Study of the Fabrication of Zinc Oxide Nanowires and Its Dye-sensitized Solar Cell Applications by : Mallarie DeShea McCune
Download or read book Fundamental Study of the Fabrication of Zinc Oxide Nanowires and Its Dye-sensitized Solar Cell Applications written by Mallarie DeShea McCune and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of its excellent and unique physical properties, ZnO nanowires have been widely used in numerous scientific fields such as sensors, solar cells, nanogenerators, etc. Although it is believed that single crystal ZnO has a much higher electron transfer rate than TiO2, it was found that ZnO nanowire-based dye-sensitized solar cells (DSSCs) have lower efficiencies than TiO2 nanoparticle-based DSSCs because the density and surface area of ZnO nanowires are usually lower than that of TiO2 nanoparticles, limiting the cell's light absorption, and because the open-root structure of ZnO nanowires results in electron back transfer that causes charge shortage of the cell. Here, experimental studies were performed that utilize strategic manipulations of the design of the ZnO nanowire based DSSCs in efforts to address and solve its key challenges. It was shown that by incorporating various blocking layers into the design of the cell, the performance of the DSSC can be improved. Specifically, by placing a hybrid blocking layer of TiO2-P4VP polymer between the substrate and the ZnO nanowires, the conversion efficiency of the cell was 43 times higher than that of a cell without this blocking layer due to the reduction of electron back transfer. Furthermore, in efforts to improve the surface area of the ZnO nanowire array, unique three dimensional structures of ZnO nanowires were fabricated. It was found that by significantly improving the overall density and surface area of the ZnO nanowire array through distinctive hierarchal nanowire structures, the light harvesting efficiency and electron transport were enhanced allowing the DSSC to reach 5.20%, the highest reported value for 3D ZnO NW based DSSCs. Additionally, the development of a theoretical model was explored in efforts to investigate how the geometry of ZnO nanowires affects the incident photon-to-current conversion efficiency of 1D ZnO nanowire-based N719-sensitized solar cells at the maximum absorption wavelength of 543 nm.

Download or read book Controllable Fabrication of Zinc Oxide Functional Nano-/micro-structure in Aqueous Solution written by Xiaodong Yan and published by . This book was released on 2010 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanostructures of ZnO show intriguing chemical, electrical, and physical properties and are promising for a broad range of applications in catalysis, electronics and photonics. Cost-effective techniques that can be used to prepare structures with controllable compositional, structural, and functional properties are fundamental to the utilization of ZnO in small scale devices with enhanced performance. Although many methods have been developed to fabricate ZnO nanostructures, systematic research on functional materials development based on ZnO is still needed as this fascinating material probably has the richest family of low-dimensional nanostructures. The research reported in this thesis aims to develop ZnO-based nanostructural materials using a facile and low-temperature aqueous solution growth approach, to analyze their compositional, mechanical, structural, and functional properties using advanced characterization techniques, to get a better understanding of the mechanisms behind nanostructure growth, and to explore their potentials in catalytic, optical, and electronic applications. In the first part of this thesis, low-dimensional ZnO nano-/micro-rods with tailored structural property (growth direction, aspect ratio, and surface distribution density) were grown on glass substrates in aqueous solutions containing zinc salt and hexamethylenetetramine at temperatures generally lower than 95oC. The substrates were pre-deposited with a thin layer of ZnO seeds using a magnetron sputter. The potential influences of growth conditions, typically including concentration, pH, type of zinc salt, solution temperature, reaction duration, and inorganic or organic additive, have been subjected to systematic investigation. This led to an improved understanding of the chemical reactions and nucleation/growth processes involved in the morphological evolution of ZnO-based hierarchical nanostructures. The second part of the thesis, ZnO nano-/micro-rod arrays with controllable distribution density have been successfully synthesized by adjusting the initial pH of the weak acidic growth solution. ZnO arrays with a large inter-rod space provide a good opportunity for characterizing the property of an individual rod. In this research, mechanical property tests have been successfully peformed directly on a single rod without the need of any complicated sample preparation. The electronic properties of these aligned ZnO nanorod arrays have also been explored by studying the I-V characteristics of both heterojuction and homojuction p-n devices. In next two chapters, complex ZnO structures, including nanotubes and three-dimensional ball-shaped clusters have been presented and disscussed, respectively. The morphology and microstructure of these structures were characterized by scanning electron microscopy, transmission electron microscopy, and in-situ cathodoluminescence. The corresponding growth mechanisms were proposed based on the analysis of the characterization results. Chapter 7 describes that aligned ZnO nano-rod arrays were further used as templates to prepare a novel composite nanostructure. By coating these ZnO nanorods with TiO2 nanowires using magnetron sputtering technique, a ZnO/TiO2 core-brush structure has been successfully achieved. Their morphology and microstructure have been investigated using scanning electron microscopy, transmission electron microscopy, powder X-ray diffractometer, energy-dispersive X-ray spectroscopy and X-ray Photoelectron Spectroscopy. This composite nanostructure shows a significantly enhanced photocatalytic activity in decomposition of a typical organic dye under UV and sunlight irradiation. This new structure has many other interesting properties and may have great potential in other optoelectronic applications. In the last part of this thesis, conclutions and future works are addressed according to the synthesis, characterization and application results.

Book Synopsis Synthesis of Zinc Oxide Nanostructures by Wet Oxidation Process by : Ruiqun Chen
Download or read book Synthesis of Zinc Oxide Nanostructures by Wet Oxidation Process written by Ruiqun Chen and published by . This book was released on 2011 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The studies on zinc oxide (ZnO) nanostructures have been intensified worldwide in the last decade. This is because ZnO as a semiconductor material has some unique properties, such as a wideband gap of 3.37 eV and high exciton energy of 60 meV at room temperature. This makes ZnO a potential and low cost substitute for GaN for blue to ultra-violet (UV) light emitting applications. Furthermore, it is known that ZnO material can easily form various nanostructures such as nanowires and nanobelt, which have the potential for catalysis or solar cell applications due to their high specific surface area and reactivity. Up to now, a large range of ZnO novel nanostructures has been synthesized by different groups with different methods. However, most of the current used techniques either has problems regarding to the requirements for high temperature and/or vacuum conditions incorporating the necessity of using expensive equipments, or difficulties with quality control and pollution. The focus of this thesis research is on the development of an alternative way of producing high quality ZnO nanostructures at moderate temperatures with low requirements in regard to facilities and experimental conditions. The method is wet oxidation, where Zn precursor is prepared by magnetron sputtering and oxidation of the Zn precursor films in wet O2 to produce ZnO nanostructures. In this thesis, various experimental factors were studied for their impacts on the formation of ZnO nanostructures. The growth mechanism of the ZnO nanostructures was then derived and checked with the experimental results. The structural and optical properties of the ZnO nanostructures were characterized by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), cathodoluminescence (CL) and photoluminescence (PL) measurements to gain the understanding of the growth process in wet oxidation. The doping methods for the wet-oxidation technique have been developed in two ways. Ag doping was achieved by mixing small amount of Ag into Zn precursor in advance of wet oxidation; and during the wet oxidation, the Ag atom would diffuse into the ZnO nanostructures to form Ag doping. Ag doping was confirmed by SEM, TEM, X-ray photoelectron spectroscopy (XPS) and PL. However, TEM observation showed that Ag doping was non-uniform in the ZnO nanowires, with a concentration gradient along the nanowire growth direction. XPS results demonstrated that the doped Ag existed in 1+ and 2+ chemical states, rather than in the metallic element state. PL spectra indicated that Ag doped ZnO nanowires had better light emission than the un-doped ZnO. N doping was conducted by introducing NH3 into the wet oxidation atmosphere, so that Zn could react with NH3 at the same time as being oxidized. SEM studies demonstrated that the nanowires grew better from Ag-Zn precursor films than from Zn precursor films with the same oxidation conditions. The presence of Ag reduced the temperature required for the Zn-NH3 reaction to take place. This resulted in the amount of Zn2N3 crystals being so large that it could be observed under TEM. The Zn2N3 crystals would transform to ZnO during the oxidation process with certain amount of N atoms remaining in the crystal lattice: this was confirmed by XPS measurement. Wet oxidation can also be used to produce ZnO and ZnO/TiO2 porous films. The porous structure was formed by reactive sputtering and preserved during wet oxidation. TiO2 nano-clusters in anatase phase were formed on the surface of the ZnO/TiO2 porous film after the wet oxidation, and the porous ZnO/TiO2 film showed enhanced PL spectrum in visible light range. The enhanced PL emission is believed to come from TiO2 due to its resonant effect with ZnO. Due to the large surface area resulted from the high porosity, ZnO and ZnO/TiO2 films have shown great photocatalysis activity for degradation of organic compounds. The ZnO/TiO2 porous film showed a better performance under visible light than the ZnO porous film, and more than 70% of the estrone could be degraded within 4 hr under visible light irradiation, with ZnO/TiO2 porous film as the catalyst. A further increase of TiO2 content in the porous film using the sol-gel method can increase the degradation percentage to more than 80% within the same time period. These tests demonstrated that these porous films would have great potential in the photocatalysis application. Some directions of future development for this research are suggested in the last part of this thesis.

This book was released on 2013 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: AbstractNano/micro scale devices have attracted a lot of interest due to the emergence of wearable/portable devices. One of the challenging tasks in the miniaturization is to reduce the size and weight of the powering unit. Harvesting mechanical energy and making the device a self-powered one, not only helps in reducing the size/weight ratio but also in designing a maintenance free and sustainable device. Piezoelectric energy harvesting research has gained new momentum with the discovery of piezoelectric charges in semiconducting zinc oxide nanowires (ZnO NWs). Semiconducting ZnO NWs provide an opportunity to integrate with electronic devices and circuits directly unlike non-conducting traditional piezoelectric materials. The coupling of piezoelectric and semiconducting properties was used to design energy generating devices called nanogenerators (NGs). The basic working principle involves application of a mechanical force to create a piezopotential across the wurtzite structured NWs and this piezopotential is channelled employing metal-semiconducting pathways such as p-n junctions. These junctions also play a key role in various other devices such as solar cells, capacitors, fuel cells and water splitting devices. This thesis concentrates mainly on the fabrication of semiconducting piezoelectric nanowires on functionalised flexible substrates and the junctions thereby obtained. It is based on the idea that ZnO NWs can be grown directly on poly(3,4-ethylendioxydithiophene) (PEDOT) or graphene-functionalised substrates using low temperature aqueous synthesis. ZnO NWs can be fabricated using a low temperature aqueous processing route on flexible substrates and fibres. ZnO creates a wide variety of nanostructures due to the polar terminating layers and the surface chemistry of the substrate. The position of the substrate in the growth solution was therefore investigated and found to dictate the morphology and aspect ratio of the nanostructure in seed mediated low temperature aqueous synthesis on polyethersulfone (PES)-based flexible substrates. Vapour phase polymerisation was used to fabricate PEDOT coated 2-D and 3-D PES. To produce graphene-coated flexible substrates, colloidal graphene was synthesized and functionalised onto 2-D and 3-D PES using layer by layer technique (LbL) with polyelectrolytes such as polyallylamine hydrochloride (PAH) and polystyrenesulfonate (PSS). The LbL modification was achieved by exploiting the surface functional groups in the colloidal graphene. Various surface treatments and heat treatments were carried out to tune the system to obtain higher conductivity. ZnO seed solution was coated and NWs were grown on the functionalized substrates. The newly formed junctions were characterised for their I-V characteristics to determine if they have similar function to junctions formed with ZnO on ITO or metals. ZnO NWs grown on PEDOT shows an ohmic contact and gives linear I-V characteristics. On the other hand when a PEDOT coated substrate was made to form a junction at the top of the ZnO NWs, it forms a Schottky contact and gives rectification. However the ZnO-graphene interface shows a Schottky contact. When a top graphene electrode was made to form a junction with ZnO NWs grown on graphene, the I-V characteristics shows a symmetrical and rectifying junction on both sides. Nanogenerators were designed and tested using ZnO NWs grown on PEDOT coated 2-D and 3-D PES. Thus, the fabricated PEDOT-NGs produced a higher current by a factor of 106 and a 102 times increase in the voltage compared to the traditional ITO grown NG design. Vapour phase polymerised PEDOT on flexible substrates eliminated the use of expensive and less efficient electrodes such as ITO and Au. It has also been shown that this approach can be extended to fibre substrates by sandwiching them between PEDOT sheets which make them more suitable for wearable energy harvesting with 102 times improved efficiency compared to ITO sandwiched fibre NG. The higher performance of PEDOT NGs was accounted by the new junctions formed at the interfaces which reduce the screening of free charge carriers in the system. Graphene NGs were fabricated using gold top electrodes. The NG fabricated on surface treated PES was found to outperform the NG fabricated without surface treatment due to the higher conductivity of the surface treated electrode. The output of the surface treated NG was found to be much less than the ITO based or PEDOT based NGs.

This book was released on 2019-09-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with novel aspects and perspectives in metal oxide and hybrid material fabrication. The contributions are mainly focused on the search for a new group of advanced materials with designed physicochemical properties, especially an expanded porous structure and defined surface activity. The proposed technological procedures result in an enhanced activity of the synthesized hybrid materials, which is of great importance when considering their potential fields of application. The use of such materials in different technological disciplines, including aspects associated with environmental protection, allows for the verification of the proposed synthesis method. Thus, it can be stated that those aspects are of interdisciplinary character and may be located at the interface of three scientific disciplines—chemistry, materials science, and engineering—as well as environmental protection. Furthermore, the presented scientific scope is in some way an answer to the continuous demand for such types of materials and opens new perspectives for their practical use

Book Synopsis Stress Analysis of Fiber-reinforced Composite Materials by : M. W. Hyer
Download or read book Stress Analysis of Fiber-reinforced Composite Materials written by M. W. Hyer and published by DEStech Publications, Inc. This book was released on 2009 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updated and improved, Stress Analysis of Fiber-Reinforced Composite Materials, Hyer's work remains the definitive introduction to the use of mechanics to understand stresses in composites caused by deformations, loading, and temperature changes. In contrast to a materials science approach, Hyer emphasizes the micromechanics of stress and deformation for composite material analysis. The book provides invaluable analytic tools for students and engineers seeking to understand composite properties and failure limits. A key feature is a series of analytic problems continuing throughout the text, starting from relatively simple problems, which are built up step-by-step with accompanying calculations. The problem series uses the same material properties, so the impact of the elastic and thermal expansion properties for a single-layer of FR material on the stress, strains, elastic properties, thermal expansion and failure stress of cross-ply and angle-ply symmetric and unsymmetric laminates can be evaluated. The book shows how thermally induced stresses and strains due to curing, add to or subtract from those due to applied loads.Another important element, and one unique to this book, is an emphasis on the difference between specifying the applied loads, i.e., force and moment results, often the case in practice, versus specifying strains and curvatures and determining the subsequent stresses and force and moment results. This represents a fundamental distinction in solid mechanics.
