Fabrication and Characterization of Au/TiO2 Catalysts for Low Temperature CO Oxidation
(2024-10-07)CO oxidation is the reaction between carbon monoxide and oxygen forming carbon dioxide, as described by 2CO + O2 → 2CO2. Gold (Au) being chemically highly inert is not expected to be a good catalyst but exhibits an ... -
Simulation of light-absorbing microparticles in an optical landscape
(2024-06-10)Simulating the dynamics of active particles play a key role in understanding the many behaviours active matter can exhibit. Experimental studies are more costly than simulations in this regard, as there is much work that ... -
Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging
(2023-11-29)Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we ... -
Decoding the surface code using graph neural networks
(2023-10-17)Quantum error correction is essential to achieve fault-tolerant quantum computation in the presence of noisy qubits. Among the most promising approaches to quantum error correction is the surface code, thanks to a scalable ... -
Development of a DEM-FEM framework for infrastructure simulations
(2022-09-20)This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with ... -
Quantum Error Correction Using Graph Neural Networks
(2021-06-17)A graph neural network (GNN) is constructed and trained with a purpose of using it as a quantum error correction decoder for depolarized noise on the surface code. Since associating syndromes on the surface code with ... -
Topological Band Theory, An Overview
(2021-06-14)Topological insulators, superconductors and semi-metals are states of ma er with unique features such as quantized macroscopic observables and robust, gapless edge states. ese states can not be explained by standard ... -
Opto-vibrational coupling in molecular solar thermal storage materials: Electronic structure calculations and neural-networkbased analysis Giannis Kostaras Degree project
(2021-01-26)Molecular solar thermal storage materials are proposed as a clean, renewable energy solution for a world with ever increasing energy needs. Norbornadiene is an organic compound suitable for molecular solar thermal storage ...
