- Description:
- Conventional cross-linked polymers are widely used owing to their outstanding stability and performance. However, permanent cross-links in these polymer networks prevent them from being recycled or reprocessed at the end of life, leading to major sustainability and economic losses. The recycling issue associated with polyurethane (PU) thermoset wastes exemplifies such...

- Description:
- This dissertation offers a novel interpretation of Aristotle’s notion of teaching (didaskalia). In Part I, I defend my claim that we can find in Aristotle’s works a conception of teaching, which is a crucial yet under-explored part of his theory of education. In Part II, I use this interpretation to...

- Description:
- Light trapping with standing waves has been achieved using photonic bandgap crystals, metal-dielectric waveguides and periodic metal nanocavity arrays. Compared with photonic materials, plasmonic metal nanocavities can provide light confinement at the sub-wavelength scale with strong near-field electric enhancement. The localized surface plasmons of individual metal nanoparticles can collectively couple...

- Description:
- The social groups to which individuals belong, as well as the identities that result from these group memberships, exert powerful influences on their political attitudes. Additionally, political elites offer cues that shape these same preferences—often by targeting and interacting with identities. However, there remain underexplored pathways by which elites can...

- Description:
- As technology scales down, challenges in fabrication, thermal stress, and in-field degradation have put the reliability of processors at risk. Among different fault types, transient faults manifest themselves frequently due to high chip density, aggressive voltage scaling, and high clock frequency. Some dependable processor architectures have been proposed to counter...

- Description:
- This thesis investigates various aspects of productivity. In the first chapter I investigate the role of consumer demand in generating productivity dispersion. In particular, I study how differences in consumer preferences across the household income distribution generate dispersion in markups across the Indian manufacturing sector. I find that this consumer...

- Description:
- The high-temperature oxidation/reduction behaviors of iron and its oxides are important to a variety of energy conversion and storage technologies, such as the solid-oxide iron-air battery and chemical looping combustion. The useful lifetime of iron redox materials is limited, however, by structural degradation arising from (i) sintering, accelerated by phase...
