The unprecedented crimes of World War Two, especially those committed by the Nazi state, unleashed an equally unprecedented effort to hold perpetrators accountable and secure justice for millions of victims. This effort encompassed hundreds of trials of thousands of individuals in the immediate postwar period and continues to the present...
The anode and cathode are main components in a battery system. In this dissertation, Group IV inter-metallics and LiMn2O4 are studied as anode and cathode materials for Li-ion batteries respectively. Preliminary investigation of a multi-valent cathode material for next generation batteries is also introduced.
Group IV inter-metallics electrochemically alloy with...
The studies presented in this dissertation combine radiogenic and stable strontium isotope ratios (87Sr/86Sr and 88/86Sr, respectively), radiogenic and stable carbon isotope ratios (Δ14C and 13C, respectively), and bulk ion geochemistry to trace the sources and cycling of C in three glaciated environments (New Zealand, Iceland, and Greenland). A primary...
One seismologist’s noise is another seismologist’s signal. What was once disregarded is now routinely processed as dense arrays of broadband seismometers continuously record small amplitude Earth motions, presenting an immense wealth of data. This dissertation presents three projects where ambient seismic noise, generated by ocean wave interactions with the solid...
Greater interest in self-directed professions, like entrepreneurship, have led to a growth in informal workplace communities and social technologies that support new ways of working. However, we have little understanding of how these socio-technical environments support opportunities for professional skill development. The goal of this dissertation is to understand how...
Understanding electrical circuits can be difficult for novices of all ages (Grotzer & Sudbury, 2000; Osborne, 1983; Shipstone, 1984; Tarciso Borges, 1999). Research shows that novices tend to have inadequate understandings of what happens at the level of atoms and electrons, leading to difficulty predicting the outcomes of electrical circuits...
X-ray Fluorescence Microscopy (XFM) is a useful technique for study of biological samples. XFM was used to map and quantify endogenous biological elements as well as exogenous materials in biological samples, such as the distribution of titanium dioxide (TiO2) nanoparticles. TiO2 nanoparticles are produced for many different purposes, including development...
Totipotent cells have the highest developmental potential and can only be created by nuclear transfer into oocytes. Identities of maternal factors that can induce this reprogramming remain a mystery. In this report, we demonstrate induction of totipotency on mouse embryonic stem cells by introducing six factors, Hist1h2aa, H3f3b, H1foo, p-Npm2,...
Metabolic engineering of microorganisms to produce useful compounds from renewable substrates is a promising means for sustainable, on-demand production of chemicals. However, efforts to design and engineer microbial cell factories are constrained by costly and slow “build” times in which each genetic variation requires re-engineering a new strain for each...
