The effects of spatial confinement and oxygen stoichiometry on complex metal oxides
… and understand the spatial confinement and oxygen stoichiometry effect on complex metal oxides to pave the way for oxide electronics. To achieve this goal, I first investigate the properties of the La2/3Sr1/3MnO3 (LSMO) thin films of different thicknesses with different oxygen deficient …

Dynamics of oxygen penetration and diffusion into horse skeletal myoglobin revealed by quenching of zinc protoporphyrin IX fluorescence
Oxygen quenching of tryptophan fluorescence in a number of globular proteins provided some of the early experimental evidence for conformational fluctuations in proteins. Gratton et al. (Biophysical J. 1984. 45:789-794) proposed a sequential two step model called the dynamic model for oxygen …

Voltage programmable materials
… and magnetism all depend sensitively on oxygen stoichiometry and defect structure at the metal/metal-oxide interface. The possibility to dynamically control interface characteristics through electric-field-induced oxygen transport and electrochemical interface reactions paves the way …

Lipidic Cubic Phase Microcrystallization and its Application in Serial Crystallography
… cell to thrive. In humans and other organisms, oxygen is used as the final electron acceptor to drive reactions that pump protons across the membrane to create an electrochemical proton gradient. This electrochemical proton gradient is then harvested for the production of ATP, the currency of …

Switching hybrid polymers with physically and covalently entrapped organic photochromes
… presence of stabilisers, also the reduction of oxygen migration into the coating (by a hard top coat and an inorganic anti reflective coating) strongly increases stability of photochromes. Finally, it was found that the separation of photochromes within two (or more) different layers leads to a …

Synthetic and mechanistic aspects of the reactions of α-diazosulfoxides
… However, a competing reaction pathway involving oxygen migration from sulfur to oxygen was also observed. Critically, isomerisation of α-oxosulfine stereoisomers was observed directly by 1H NMR spectroscopy in this work and this observation accounts for the stereochemical outcomes of the various …

In-situ plasmon-enhanced characterization of optically accessible ultra-thin film ferroelectric devices
… on MoS2. In chapter 4, Evidence of vacancy migration assisted phase change in FE memories, this study shows the optical tracking of oxygen migration induced phase change in ultra-thin film (≤5 nm) ferroelectric devices. While Hafnia-based films have achieved ferroelectricity at single-digit …
