Book Description
CdSe(sub x)Te(sub 1-x) nanoparticles (with different stoichiometry ratio x) dispersed in silicon dioxide films have been grown by magnetron sputtering technique followed by thermal annealing. Effect of Thermal annealing conditions on the structural, compositional, optical and electronic properties of nanoparticles has been studied Using GAXRD, XPS, TEM, and spectroscopic ellipsometry techniques A structural transformation in the nanoparticle core mediated purely by surface layer effects in the case of CdTe and a spontaneous self-organization of nanoparticles into nanorods in the case of CdSe via fractal growth has been observed. Preliminary observations from the ellipsometry measurements carried out on some of these nanoparticle films shows a blue shift of absorption edge.

Book Description
Nanostructures of semiconductors and metals show novel optical and transport properties, and offer the perspective of designing materials properties with unprecedented flexibility and control. This has motivated research in the synthesis and characterization of new materials. This 2004 book brings together scientists with various levels of expertise in the growth, characterization and applications of inorganic nanostructures, such as quantum dots, nanowires and nanorods, to discuss and share developments in the field. Reports focus on techniques to prepare and characterize novel materials, investigations of novel optical and electronic properties, and novel applications, such as those that are biologically inspired. Topics include: synthesis and characterization of semiconductor quantum dots, nanoparticles and nanowires using wet chemistry and molecular beam approaches; synthesis, characterization and novel properties of metallic nanostructures; optical properties of neutral and charged excitons and exciton complexes in self-assembled quantum dots; nanoscale devices and sensors based on nanostructures and their properties; and design and characterization of quantum dot-bioconjugates and their use in assay developments.

Molecularly Imprinted Materials-- 2003

Molecularly Imprinted Materials-- 2003 PDF Author: Peter Kofinas
Publisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 136

Book Description
The availability of materials that can bind selectively to a target molecule is the key to unlocking a host of new technologies. Molecular imprinting is an established technology, which allows the synthesis of materials containing highly specific receptor sites having an affinity for a target compound. For example, molecularly imprinted materials can mimic some of the functions of enzymes through the creation of three-dimensional cavities of specific size and shape for biorecognition of bioactive compounds. This volume offers a forum for technical exchange among members of the worldwide community of scientists and engineers who work in the area of molecular imprinting. Researchers from academia, government and industry present results in applications of molecular imprinting related to catalysis, combinatorial and computational methods, new monomers and recognition strategies, sensors, drug discovery and therapy, and new molecular imprinting formats.

Radiation Effects and Ion-beam Processing of Materials

Publisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 704

Book Description
The catastrophic effect, as well as a potentially advantageous effect, from energetic beams is the instant high-energy deposition in a local volume, down to the nanoscale, and the rapid cooling processes resulting in changes in the structure and properties of materials that are hard to achieve by other methods. The challenging balance between controlling radiation damage and enhancing material properties has intrigued materials scientists and physicists, as well as engineers in the nuclear and semiconductor industry, and caused them to work closely together for many years. As clearly demonstrated in this volume, many new technologies for creating unique functional devices with energetic particle beams are based on the fundamental study of radiation-induced defect production and evolution. Scientists and engineers working in nuclear engineering, environmental sciences and functional materials share a common language and numerous opportunities for collaboration in this truly interdisciplinary area. Exciting and promising results are presented here, including the most recent progress in fundamental understanding of radiation effects using molecular dynamic (MD) and kinetic Monte Carlo (kMC) simulations, processing of monodisperse nanoparticles by ion implantation, production of a wide variety of nanostructures with the application of focused ion beams (FIB), and creating new types of nanoscale functional devices using high-energy ion tracks. These results demonstrate the important relation between fundamental research on radiation effects and the development of new types of nanoscale functional devices using energetic particles over a wide energy range. Topics include: radiation effects in nuclear materials; ion-beam processing of nanostructures; ion-beam processing of semiconductor devices; ion-beam modification of physical properties; modeling and computer simulation of beam-solid interactions; and ion-beam-assisted deposition and surface modification.

Synthesis, Characterization and Properties of Energetic/reactive Nanomaterials PDF Author: Ronald D. Armstrong
Publisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 424

Book Description
The advent of nanomaterials has introduced a new dimension in applications of energetic and reactive materials. A fundamental understanding of their synthesis mechanisms, atomic- and molecular-scale structural characteristics, and an evaluation of properties combined with modeling of the limits to those properties are required to realize the full potential of energetic and reactive nanomaterials. Many techniques have been recently developed that make it possible to exploit the benefits of the "nano" structure and design materials with desired energy release rates and energy densities, while they also improve their safety, reliability and load-bearing capability. Advances in modeling and characterization have made it possible to determine mechanisms controlling the thermal, chemical and mechanical behavior of nanomaterials. This volume brings together researchers from around the world to assess fundamental studies on synthesis, characterization of structure, and evaluation of properties of energetic/reactive nanomaterials. Applications such as new propellant formulations, underwater detonation developments, biomedical research, and combustion of nanolayered metal films for cladding materials are featured. Topics include: applications and toxicology; synthesis; characterization; characterization and theory; theory and modeling; and general discussion.
