Toward The Synthesis And Characterization Of Pb-Doped Zns Nanocrystals For Solar Energy Applications, Allison Durr
Toward The Synthesis And Characterization Of Pb-Doped Zns Nanocrystals For Solar Energy Applications, Allison Durr
Online Theses and Dissertations
Efficient and affordable energy conversion and energy storage technologies are required to meet society’s increasing demands. Semiconductor nanocrystals are particularly attractive materials for solar energy conversion applications, as their tunable optoelectronic properties can be manipulated to both optimize the absorbance of solar photons and to afford desirable electronic properties. Further tunability of binary semiconductor nanocrystal systems can be realized through substitutional doping. However, doping can be difficult, as the dopants can cause significant lattice strain in the host crystals. Lead-doped ZnS nanocrystals are one promising material for the conversion of solar photons into storable fuels such as hydrogen gas. The …
Effects Of De-Polymerization Of Cellulose In Producing Sugar From Cellulosic Biomass At Low-Temperature, Lin Ling Wu
Effects Of De-Polymerization Of Cellulose In Producing Sugar From Cellulosic Biomass At Low-Temperature, Lin Ling Wu
Online Theses and Dissertations
Lignocellulosic biomass is an abundant, renewable and environmentally friendly raw materials that can be converted into biofuels as an efficient alternative energy source. Sugar production is one of the key steps in converting biomass to fuels and chemicals. In order to enhance the accessibility of lignocellulosic biomass to catalytic enzyme, microorganism, and other types of catalysis during bioprocessing, the pre-treatment of lignocellulosic biomass is needed. To depolymerize the lignocellulosic materials, a 7% NaOH/12% urea solution was used. Selection of enzyme from Novozyme was performed, as a result, NS22074, a Cellulase complex was used throughout the research. Under the same reaction …
Deuterium Enrichment And The Kinetic Isotope Effect During Ruthenium Catalyzed Fischer-Tropsch Synthesis, Jennifer Naumovitz
Deuterium Enrichment And The Kinetic Isotope Effect During Ruthenium Catalyzed Fischer-Tropsch Synthesis, Jennifer Naumovitz
Online Theses and Dissertations
Fischer Tropsch Synthesis is a highly researched field that is still widely debated today. Research in this field could lead to many different advances, such as alternative fuel sources, explanations of abiogenic hydrocarbons and the formation of organic matter in the solar nebula. Analysis of this synthesis was carried out with a ruthenium catalyst at controlled temperatures and pressures. Two types of experiments were performed: H2/D2 switching and competitive methods. The products showed that the hydrocarbon production rate was slightly increased when syngas was switched to D2/CO. Also, the H/D ratios of the hydrocarbons produced by the FT reaction using …
