Dedication To my parents, Gary and Carol, and to my loving girlfriend Connie. v Acknowledgements I would like to express my gratitude to my supervising, Professor Joe C. Campbell, for showing me the exciting world of nitride-based optoelectronic devices. His wise advice and constant support has been the most important aspect of my research, inspiring all of the work I have accomplished. Joe Cam...
Carbonitride Coatings from Tetrakis(diethylamido)chromium and Pyrolysis Mechanism of this Single-Source Precursor Francis Maury* and Franco Ossola Laboratoire de Réactivité et Protection des Matériaux, CNRS-INPT, Ecole Nationale Supérieure de Chimie, 118 route de Narbonne, 31077 Toulouse cedex 4, France Istituto di Chimica e Tecnologie Inorganiche e dei Materiali Avanzati, Area della Ricerca de...
Abstract Foeniculum vulgare Mill. is a medicinal plant, used as flavouring agent. The essential oil from F. has potential antimicrobial and insecticidal effects, can be in food industry order to protect the resources products against microbial pest’s contamination. aim of research was characterize volatile components by Gas Chromatography/Mass Spectrometry (GC/MS) Chromatography (GC-FID) observ...
Thin film composite membranes of polyamide prepared by vapour phase interfacial polymerization between a diamine and an acyl chloride are applied to nanofiltration.
Zinc oxide is a unique material that exhibits semiconducting and piezoelectric dual properties. Using a solid–vapour phase thermal sublimation technique, nanocombs, nanorings, nanohelixes/nanosprings, nanobelts, nanowires and nanocages of ZnO have been synthesized under specific growth conditions. These unique nanostructures unambiguously demonstrate that ZnO probably has the richest family of ...
Vapour and liquid phases of a simple batch distillation may be separated theoretically at equilibrium at a certain pressure and temperature state. A small separation effect can be achieved by this, because only one equilibrium stage between liquid and vapour phase is thereby realised. Contacting again vapour and liquid flows leaving one single stage in co-current mode, no further separation eff...
The formation of organic films on gold employing N-heterocyclic carbenes (NHCs) has been previously shown to be a useful strategy for generating stable organic films. However, NHCs or NHC precursors typically require inert atmosphere and harsh conditions for their generation and use. Herein we describe the use of benzimidazolium hydrogen carbonates as bench stable solid precursors for the prepa...
Hydride vapour phase epitaxy grown allepitaxial p-i-n structures were studied by synchrotron X-ray topography. Three types of process induced dislocations were found: short threading dislocations, long straight interfacial dislocations and circular arc dislocations. The majority of the dislocations observed are short straight threading dislocations, the density of which is typically about 5000 ...
Thermodynamic analysis of III-V semiconductor alloys grown by metalorganic vapor phase epitaxy Toshihiro Asai and David S. Dandy Dept. of Chemical Engineering, Colorado State University, Fort Collins, Colorado 80523-1370 A thermodynamic analysis has been applied to systematically study III-V semiconductor alloy deposition, including nitrides grown by metalorganic vapor phase epitaxy. The predic...
