Radiation damage quantification in elemental copper using Wigner energy storage
… of radiation damage, the irradiation and calorimetry of elemental copper were simulated using molecular dynamics code. A custom defect analysis script was used to determine the energy stored as a function of irradiation energy and defect type. Wigner energy peaks were clearly visible in …

Uranium Enrichment Signatures of Fluorinated Epoxy
… to acquire weapons. Through the use of Fast Scanning Calorimetry, this thesis shows that alpha radiation from uranium can cause a detectable change in the glass transition temperature in UV cured fluorinated epoxy (a material which can be used uranium enrichment cascades) at doses …

Assessing differential scanning calorimetry as a retrospective dosimetry method for the verification of uranium enrichment activities
… and the thermal analysis techniques differential scanning calorimetry (DSC) and fast scanning calorimetry (FSC). The DSC-PTFE system shows statistically significant sensitivity in the dose ranges expected. The FSC-PTFE system demonstrates reduced precision compared to the DSC-PTFE system, but it …

Crystallization Behavior, Tailored Microstructure, and Structure-Property Relationships of Poly(Ether Ketone Ketone) and Polyolefins
… rates on the physical and chemical properties of fast crystallizing polymers. The primary objectives were to 1) utilize advanced methodologies to accurately determine the fundamental thermodynamic value of equilibrium melting temperature (Tmo) for the semi-crystalline polymer poly(ether ketone …

Additive manufacturing of polyolefins via powder bed fusion
… and then used these temperature profiles in fast scanning calorimetry (FSC) to emulate a printed layer's thermal history. This emulation enabled prediction of the crystallinity and the shape and temperatures covered by the melting endotherm during the printing process. Investigations of …

Design, Processing, and Characterization of Nanocomposites
… process-relevant conditions were explored using fast scanning calorimetry. It was found that the PA 11 composite would need at least 0.5 s above 100 °C in order to crystallize via heterogeneous nucleation and that in the heterogeneous regime, the nucleated samples exhibited much quicker peak …

Thermomechanical Processing of Metallic Glasses
… used to form it upon quenching from the melt. A faster cooling rate will give rise to a glass of higher energy with a more disordered structure. The energy, structure and properties of a glass can also be modified after glass formation. Through various thermomechanical methods, it is possible to …
