With the help of synthesis experiments, in-situ laser diagnostics and molecular dynamics simulations, it investigates the growth of nanoparticles in flames and their deposition in boundary layers at a macroscopic flow field scale, as well as particle and molecular scale issues such as the interaction force between particles, how the collision rate is enhanced by attractive forces, and how the nano-scale coalescence process is influenced by the high surface curvature – all of which are crucial to understanding nanoparticle transport phenomena at high temperatures. The book also reports on a novel in-situ laser diagnostics phenomenon called phase-selective laser-induced breakdown spectroscopy and related applications for tracing gas-to-particle transitions and measuring local particle volume fractions in nano-aerosols.

Book excerpt: Pulsed laser–based techniques for depositing and processing materials are an important area of modern experimental and theoretical scientific research and development, with promising, challenging opportunities in the fields of nanofabrication and nanostructuring. Understanding the interplay between deposition/processing conditions, laser parameters, as well as material properties and dimensionality is demanding for improved fundamental knowledge and novel applications. This book introduces and discusses the basic principles of pulsed laser–matter interaction, with a focus on its peculiarities and perspectives compared to other conventional techniques and state-of-the-art applications. The book starts with an overview of the growth topics, followed by a discussion of laser–matter interaction depending on laser pulse duration, background conditions, materials, and combination of materials and structures. The information outlines the foundation to introduce examples of laser nanostructuring/processing of materials, pointing out the importance of pulsed laser–based technologies in modern (nano)science. With respect to similar texts and monographs, the book offers a comprehensive review including bottom-up and top-down laser-induced processes for nanoparticles and nanomicrostructure generation. Theoretical models are discussed by correlation with advanced experimental protocols in order to account for the fundamentals and underline physical mechanisms of laser–matter interaction. Reputed, internationally recognized experts in the field have contributed to this book. In particular, this book is suitable for a reader (graduate students as well as postgraduates and more generally researchers) new to the subject of pulsed laser ablation in order to gain physical insight into and advanced knowledge of mechanisms and processes involved in any deposition/processing experiment based on pulsed laser–matter interaction. Since knowledge in the field is given step by step comprehensively, this book serves as a valid introduction to the field as well as a foundation for further specific readings.

This book was released on 2017-12-21 with total page 69 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology can profoundly benefit our health, environment and everyday life. In order to make this a reality, both technological and theoretical advancements of the nanomaterial synthesis methods are needed. A nanoparticle is one of the fundamental building blocks in nanotechnology and this thesis describes the control of the nucleation, growth and oxidation of titanium particles produced in a pulsed plasma. It will be shown that by controlling the process conditions both the composition (oxidationstate) and size of the particles can be varied. The experimental results are supported by theoretical modeling. If processing conditions are chosen which give a high temperature in the nanoparticle growth environment, oxygen was found to be necessary in order to nucleate the nanoparticles. The two reasons for this are 1: the lower vapor pressure of a titanium oxide cluster compared to a titanium cluster, meaning a lower probability of evaporation, and 2: the ability of a cluster to cool down by ejecting an oxygen atom when an oxygen molecule condenses on its surface. When the oxygen gas flow was slightly increased, the nanoparticle yield and oxidation state increased. A further increase caused a decrease in particle yield which is attributed to a slight oxidation ofthe cathode. By varying the oxygen flow, it was possible to control the oxidation state of the nanoparticles without fully oxidizing the cathode. Pure titanium nanoparticles could not be produced in a high vacuum system because oxygen containing gases such as residual water vapour have a profound influence on nanoparticle yield and composition. In an ultrahigh vacuum system titanium nanoparticles without significantoxygen contamination were produced by reducing the temperature of the growth environment and increasing the pressure of an argon-helium gas mixture within whichthe nanoparticles grew. The dimer formation rate necessary for this is only achievable at higher pressures. After a dimer has formed, it needs to grow by colliding with a titanium atom followed by cooling by collisions with multiple buffer gas atoms. The condensation event heats up the cluster to a temperature much higher than the gas temperature, where it is during a short time susceptible to evaporation. When the clusters’ internal energy has decreased by collisions with the gas to less than the energy required to evaporate a titanium atom, it is temporarily stable until the next condensation event occurs. The temperature difference by which the cluster has to cool down before it is temporarily stable is exactly as many kelvins as the gas temperature.The addition of helium was found to decrease the temperature of the gas, making it possible for nanoparticles of pure titanium to grow. The process window where this is possible was determined and the results presented opens up new possibilities to synthesize particles with a controlled contamination level and deposition rate.The size of the nanoparticles has been controlled by three means. The first is to change the electrical potential around the growth zone, which allows for size (diameter) control in the order of 25 to 75 nm without influencing the oxygen content of the particles. The second means is by increasing the pressure which decreases the ambipolar diffusion rate of the ions resulting in a higher growth material density. By doing this, the particle size can be increased from 50 to 250 nm, however the oxygen content also increases with increasing pressure when this is done in a high vacuum system. The last means of size control was by adding a helium flow to the process where higher flows resulted in smaller nanoparticle sizes. When changing the pressure in high vacuum, the morphology of the nanoparticles could be controlled. At low pressures, highly faceted near spherical particles were produced. Increasing the pressure caused the formation of cubic particles which appear to ‘fracture’ at higher pressures. At the highest pressure investigated, the particles became poly-crystalline with a cauliflower shape and this morphology was attributed to a lowad atom mobility. The ability to control the size, morphology and composition of the nanoparticles determines the success of applying the process to manufacture devices. In related work presented in this thesis it is shown that 150-200 nm molybdenum particles with cauliflower morphology were found to scatter light in which made them useful in photovoltaic applications, and the size of titanium dioxide nanoparticles were found to influence the selectivity of graphene based gas sensors.

Available in PDF, EPUB and Kindle. Book excerpt: In this study, we demonstrated nanoparticle manipulation and its application in advanced nanofabrication and chemical sensing by using a laser-induced surface bubble. A laser-induced surface bubble refers to a bubble that is generated on a liquid-solid interface by using a laser. The laser-induced surface bubble is generated on a gold-coated glass substrate by focusing a continuous-wave (CW) laser on a solid-liquid interface. The laser heats up the solid surface and generates a surface bubble on the solid-liquid interface. We call it a surface bubble because the bubble stick on the surface and is easy to manipulate. Once a surface bubble is generated on the solid-liquid interface, a strong convective flow is induced in the liquid, which can be used to fabricate ring-shaped disk structures for chemical sensing. The size and position of the surface bubble can be dynamically adjusted by changing the power and position of the laser spot. Nanoparticles of different sizes and materials are fabricated on a glass substrate by using the surface bubble. We studied this surface-bubble based fabrication process by investigating different fabrication parameters, such as laser power, laser exposure time, and laser chopping frequency. The possibility of multiple-layer nanofabrication is also investigated by fabricating gold and silver nanoparticles in a layer-upon-layer manner. The final fabricated ring-shaped nanostructure is used as a chemical sensor for the detection of Rhodamine 6G. The nanoparticle manipulation method based on the laser-induced surface bubble enables the possibility of advanced nanofabrication and chemical sensing.

Available in PDF, EPUB and Kindle. Book excerpt: Modification of nanostructures via laser processing is of great interest for a wide range of applications such as aerospace and the storage of nuclear waste. The primary goal of this dissertation is to improve the understanding of nanostructures through two primary routes: the modification of aerogels and pulsed laser ablation in ethanol. A new class of materials, patterned aerogels, was fabricated by photopolymerizing selected regions of homogeneous aerogel monoliths using visible light. The characterization and fabrication of functionally graded, cellular and compositionally anisotropic aerogels and ceramics is discussed. Visible light was utilized due to it's minimal absorption and scattering by organic molecules and oxide nanoparticles within wet gels. This allowed for the fabrication of deeply penetrating, well resolved patterns. Similarly, nanoporous monoliths with a typical aerogel core and a mechanically robust exterior ceramic layer were synthesized from silica aerogels cross-linked with polyacrylonitrile. Simple variations of the exposure geometry allowed fabrication of a wide variety of anisotropic materials without requiring layering or bonding. Nanoparticle solutions were prepared by laser ablation of metal foils (Fe and Mo) in ethanol. Ablation of Fe generated Fe3O4 and Fe3C nanoparticles which were superparamagnetic with a saturation magnetization Ms = 124 emu/g. Zero field cooled (ZFC) measurements collected at an applied field of 50 Oe displayed a maximum magnetic susceptibility at 120 K with a broad distribution. Field cooled (FC) measurements showed a thermal hysteresis indicative of temperature dependent magnetic viscosity. Pulsed laser ablation of a Mo foil in ethanol generated inhomogeneous nanoparticles where Mo and MoC coexisted within the same aggregate. Formation of these unique nanoparticles is likely due to phase separation that occurs when a high temperature carbide phase cools after the laser pulse terminates. Similarly, magnetic nanoparticle suspensions were generated by pulsed laser ablation of Fe and Mo in ethanol. The formation of several carbide phases with no discernable alloy formation was seen. A decrease in magnetization with a decrease in Fe concentration was seen which was reconciled with the decreased Fe content in the system. However, at Fe concentrations below [approximately] 40%, an increase in Ms and Hc was observed which was reconciled with the disappearance of the [epsilon]-Fe3C. TEM analysis showed the formation of core-shell nanoparticles and Energy Filtered TEM showed the distribution of Fe-based nanoparticles in the suspensions.

Available in PDF, EPUB and Kindle. Book excerpt: The slowing of Pt nanoparticles in argon background gas was characterized by Rayleigh scattering imaging using a plume of nanoparticles generated by femtosecond laser through thin film ablation (fs-TTFA) of 20 nanometers-thick Pt films. The ablation was performed at threshold laser energy fluences for complete film removal to provide a well-defined plume consisting almost entirely of nanoparticles traveling with a narrow velocity distribution, providing a unique system to unambiguously characterize the slowing of nanoparticles during interaction with background gases. Nanoparticles of ~200 nm diameter were found to decelerate in background Ar gas with pressures less than 50 Torr in good agreement with a linear drag model in the Epstein regime. Based on this model, the stopping distance of small nanoparticles in the plume was predicted and tested by particle collection in an off-axis geometry, and size distribution analysis by transmission electron microscopy. These results permit a basis to interpret nanoparticle propagation through background gases in laser ablation plumes that contain mixed components.

This book was released on 2009 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomanufacturing is a term used to describe either the production of nanoscale materials, or to describe the manufacturing of parts ̀bottom up' from nanoscale material or ̀top down' in smallest steps for high precision. In recent years, nanomanufacturing is facing a new and broadened definition the essential themes lie on low cost, scalability, reliability and sustainability, besides the conventional requirements. The emphasis on this technology is towards realizing the low cost and large area manufacturing with control and benefits from nanoscale structures and nano enabled properties. The newly defined nanomanufacturing is expected to find extensive new applications in the large area electronics and renewable energy industries. Nanomanufacturing based on solution processed nanoparticles is a promising approach towards this goal and is currently under intense research. This process significantly simplifies the manufacturing process and enables potential applications that are low temperature and extremely low cost. The solution deposition eliminates the need of multiple steps and vacuum deposition. It is capable of being integrated into the simple process, i.e. roll-to-roll manufacturing, to increase yield and process area. The suppressed melting temperature of nanoparticles also eliminates the need of high temperature processing. In solution processing, in general, nanoparticles prepared chemically with controlled stability and compositions are deposited in solution phase (e.g. printing) followed by annealing and/or nanopatterning steps for achieving the required spatial resolution and reasonable electrical and optical properties. Laser processing, including annealing/sintering and ablation, of solution deposited nanoparticles is a new and interesting process that has barely been explored. Not only this process can take advantage of laser processing for low cost, low temperature device fabrication, but also a large amount of physics can be explored including laser-nanomaterial interaction, nanoscale heat/mass transport, defects / grain boundaries evolution, semiconductor device physics and photonics, etc. The present study examined various components in the low cost nanomanufacturing process, including laser annealing of semiconductor and metallic nanoparticles, optical characterization of sintering process and scalable nanopatterning techniques. The emphasis is on both demonstration of novel processes and working devices as well as fundamental experimental and numerical studies of transport phenomena involved in laser induced solid state and melt-mediated nanoparticle coalescence. Firstly, to provide insight into the transport phenomena involved in laser induced non-melt and melt-mediated nanoparticle coalescence, experimental and numerical studies were performed. The Molecular Dynamics simulation was adopted to study the solid-state nanoparticle sintering by laser heating. The comparison between MD and macroscopic model reveals the unique mechanisms in sub-10nm nanoparticles sintering suggesting enhanced neck growth rate can be expected for nanoparticle with size below 10nm. The melt-mediated nanoparticle coalescence induced by ns laser is probed in-situ by a pump-and-probe technique. The probing results reveal several important characteristic times during laser annealing that will determine the morphology and crystalline structures of the laser processed film: characteristic coalescence time, cooling and resolidification times. The coalescence time compares favorably with MD simulation. Secondly, the laser annealing of metal oxide nanoparticles for electronics and photovoltaics are demonstrated. Solution deposited ZnO nanoparticles can be transformed into active channel layer of thin film transistors (TFTs) by Excimer laser annealing (ELA). The device shows mobility ̃0.1 cm2/V-s and current on/off ratios of more than 104. The properties of the laser annealed films were characterized by scanning electron microscopy, high-resolution TEM, DC conductance, and photoluminescence measurements. Furthermore, ELA is combined with spray deposition of TiO2 nanoparticle to fabricate dye sensitized solar cells (DSSCs) on glass and plastic substrates. All-laser-annealed TiO2 photoelectrodes achieve efficiency at ̃3.8% with Ruthenium dyes. Optical characterization of optical properties and film thickness by ellipsometry is also demonstrated for silver nanoparticle film sintering. The ellipsometric measurement is found to be robust in capturing the percolation transition, dielectric constant and film thickness evolutions. The non-contact optical measurement is also found to correlate well with DC measurement. Finally, large-area optical near-field nanoprocessing, i.e. nanosintering and nanoablation, of solution deposited nanoparticle is demonstrated. The feature size down to ̃150nm is obtained and annealing in furnace further reduces the feature size down to ̃50nm. Nanoscale organic transistors are fabricated by nanosintered electrodes and solution deposited air-stable semiconductor polymer. Molecular Dynamics simulation is also employed to calculate the effective thermal conductivity of the nanoparticle film to facilitate thermal modeling of the nanoscale laser processing.

Book excerpt: This book deals with gas-phase nanoparticle synthesis and is intended for researchers and research students in nanomaterials science and engineering, condensed matter physics and chemistry, and aerosol science. Gas-phase nanoparticle synthesis is instrumental to nanotechnology—a field in current focus that raises hopes for environmentally benign, resource-lean manufacturing. Nanoparticles can be produced by many physical, chemical, and even biological routes. Gas-phase synthesis is particularly interesting since one can achieve accurate manufacturing control and hence industrial viability. Nanotechnology is popular today. However, basic scientific aspects of the relevant, underlying processes have not received sufficient attention. This book fills the gap in the current literature by addressing certain fundamentals of gas-phase nanoparticle synthesis. Chapters cover topics such as forces within and dynamics of nanoparticle systems, gas evaporation and deposition, laser assisted nanoparticle synthesis, and nanoparticle fabrication via flame processes. A chapter on in-situ structural studies of nanoparticles undergoing growth complements the exposition.
