My presentation outlines the research, experimental work and results from my masters of research degree into the reinforcement of silica aerogel materials with oxygen functionalized Graphene, as well as a time effective and efficient process for their manufacturing and production utilizing thermo-press technology. These materials were then tested for thermal conductivities, alongside mechanical properties.
Recent studies exploring ammonia as a green hydrogen energy carrier have established its suitability for a variety of combustion technologies including gas turbines, furnaces, and internal combustion engines. Of significant interest are ammonia/hydrogen blends, which possess combustion benefits over pure ammonia, including an extended stability range and higher laminar burning velocity. However, very few studies explore the suitability of existing materials for the manufacture of ammonia/hydrogen combustors, particularly nickel-based superalloys. In this talk, the impact of ammonia/hydrogen flame chemistry on nickel-base superalloys will be discussed, including results from thermal desorption analysis (TDA) and room temperature tensile testing, to help review their future in the green ammonia sector.
A new mathematical radiation dosimetry model used to simulate principal geometries has been developed. Using recorded stopping data and either explicitly knowing the radionuclides present in a material or determining averages from a detector, this approach can simulate radiation through any material. This unique approach exposes symmetry in simple geometries to reduce complexity and computation load, which in turn allows for modern programming languages to be utilized and results linked to more computationally demanding models (Finite Element Analysis, Monte Carlo Simulators). The reduced complexity of these models does not suffer from increased inaccuracy to similar more complex simulators (MCNP, GEANT4) allowing one to develop and scale complex models, such as spent nuclear fuel dissolution, with relative ease.
