• Beyond lexical towards to better document representations 

  Kong, Yuqi (University of Delaware, 2021)

  How documents are represented is essential for downstream text applications. In this dissertation, we break the boundary of lexical-based document representation. Endeavor to find new directions in achieving a more ...
• Activity studies of pentamethylcyclopentadienyl chromium complexes in N2 activation 

  Ahmadi Darani, Farzaneh (University of Delaware, 2021)

  The discovery of mild methods for metal mediated cleavage of the dinitrogen triple bond to produce metal nitride derivatives is a fundamental aspect of nitrogen fixation. An important step in this process is to understand ...
• How changes predict changes: a longitudinal study on mathematics motivation and engagement in first year secondary mathematics classes 

  Zhang, Xiaoxue (University of Delaware, 2021)

  Student mathematics motivation and engagement in the first year of high school is critical because of its volatility (Mangu, Middleton, & Lee, 2016) and importance for future academic advancement and career opportunities ...
• Mechanistic insights into the electrochemical CO2 reduction reaction using surface enhanced infrared spectroscopy 

  Malkani, Arnav S. (University of Delaware, 2021)

  The electrochemical CO2 reduction reaction (CO2RR) is a method to convert a greenhouse gas, CO2, into chemicals and fuels using electricity generated from renewable sources. CO is an intermediate in this process which can ...
• A logit-based stochastic user equilibrium model for the integrated scenario-based hurricane evacuation framework 

  Ha, Di (University of Delaware, 2021)

  This dissertation introduces a new traffic assignment model for use in hurricane evacuation modeling. The logit-based stochastic user equilibrium (SUE) model is designed to capture the stochastic route choice behaviors ...
• The effects of persistent mild traumatic brain injury symptoms on the neurophysiological health of adults 

  Bryk, Kelsey N. (University of Delaware, 2021)

  BACKGROUND: Mild traumatic brain injury (mTBI) accounts for approximately 70-90% of the 2.8 million TBIs sustained annually, and up to 40% of those may result in persistent symptoms lasting beyond a normal clinical recovery ...
• Bulk and surface investigation of narrow bandgap Cu(In,Ga)Se2 solar cells 

  Valdes, Nicholas (University of Delaware, 2021)

  Single-junction solar cell efficiency is limited to 33%, in which the majority of losses are due to thermalization of carriers. Thermalization can be reduced by creating solar cells with two junctions, or tandem solar ...
