Surface Modifications for Greater Cycle Life and Energy Density in Lithium-Ion Batteries

Creator:: Holstun, Tucker M.
Abstract:: Significant challenges remain before lithium-ion batteries can support the decarbonization of the transportation and power sectors required to avert catastrophic climate change. The energy density of these batteries must be increased, while decreasing the price, and maintaining or increasing their lifespan. To improve the practical energy density of existing materials,...

Understanding And Improving The Activity Of Oxygen Evolution Reaction Catalysts In Alkaline And Chloride-Containing Electrolytes

Creator:: Adiga, Prajwal Prakash
Abstract:: Water electrolysis plays a pivotal role in achieving a green hydrogen economy by sourcing electricity from intermittent renewable sources. However, the efficiency of the electrolysis process is limited by the sluggish oxygen evolution reaction (OER) kinetics, whereas the kinetics of the hydrogen evolution reaction (HER) are more facile. This thesis...

Evaluation of amorphous oxide semiconductors for thin film transistors (TFTs) and resistive random access memory (RRAM) applications

Creator:: Rajachidambaram, Jaana Saranya
Abstract:: Thin-film transistors (TFTs) are primarily used as a switching element in liquid crystal displays. Currently, amorphous silicon is the dominant TFT technology for displays, but higher performance TFTs will become necessary to enable ultra-definition resolution high-frequency large-area displays. Amorphous zinc tin oxide (ZTO) TFTs were fabricated by RF magnetron sputter...

Synthesis, surface treatment, and characterization of copper indium sulfide quantum dots

Creator:: Alemu, Yagenetfere A.
Abstract:: The need for less toxic quantum dots (QDs) has led to a significant number of investigations related to copper indium sulfide (CIS) QDs. Lower toxicity and broad band absorbance width makes CIS QDs appealing for light emitting diodes (LEDs), lasers, sensors, bio-imaging, solar cells, and computing. The optical and electronic...
