Fundamental and applied studies of organic photovoltaic systems

Hill, Caleb M. (University of Alabama Libraries, 2014)

Presented here are applied and fundamental studies of model organic photovoltaic (OPV) systems. Graphene oxide (GO) nanosheets were investigated as a potential electron acceptor in bulk heterojunction organic solar cells ...
Hemibiquinones: synthesis and computational validation of an asymmetric d—a biphenyl system

Meany, Joseph E. (University of Alabama Libraries, 2016)

In order to help determine the governing characteristics behind asymmetric current flow in molecules (molecular rectification), it is important to establish size limitations for the electron transfer processes which make ...
Ionic liquids platform for biomass dissolution leading to advanced biocomposite materials

Maxim, Mirela Liliana (University of Alabama Libraries, 2012)

The focus on biomass as a renewable resource has been triggered by the increasing demand for non-renewable supplies and the distress of imminent depletion of petroleum reserves. The term "biorefinery" has been defined in ...
Metal oxide thin films by chemical vapor deposition for photocatalytic water splitting

Panikar, Archana Sathyaseelan (University of Alabama Libraries, 2016)

Photoelectrochemical cells (PEC) are devices which convert solar energy into consumable chemical energy by splitting water into oxygen and hydrogen. Photocatalytic activity at a semiconductor oxide surface forms the backbone ...
Nanostructured silver for applications in surface enhanced Raman spectroscopy and photoelectrochemical reactions

Clayton, Daniel Adam (University of Alabama Libraries, 2014)

Initial work focused on characterizing silver and its surface enhanced Raman spectroscopy (SERS) capabilities. Silver nanowires were chosen as an ideal material and scanning confocal microscopy studies were performed to ...
Plasmonic nanoparticles for applications in light scattering spectroelectrochemistry and photoelectrochemical water splitting

Ma, Yanxiao (University of Alabama Libraries, 2019)

Plasmonic gold nanoparticles (NPs) have interesting properties in both surface plasmon resonance and electrocatalytic reactions. However, the mechanism of local redox events at electrocatalytic Au NPs remains uncertain. ...
Spectroscopic, structural, and electrical characterization of thin films vapor-deposited from the spin-crossover complex Fe(phen)_2 (NCS)_2

Ellingsworth, Edward (University of Alabama Libraries, 2015)

Thin films (~100 nm) have been prepared of the prototypical spin-crossover complex Fe(phen)2(NCS)2 (phen = 1,10-phenanthroline). Initial attempts to prepare these films by direct vapor deposition yielded films of a different ...
Synthesis and applications of hierarchically porous metal and metal oxide monolithic materials

Sayler, Franchessa Maddox (University of Alabama Libraries, 2013)

A nanocasting method for synthesizing a broad range of hierarchically porous, high surface area metal and metal oxide monolithic materials was developed. The importance of a well-connected hard template was established ...
Synthesis and characterization of hierarchically porous metal, metal oxide, and carbon monoliths with highly ordered nanostructure

Grano, Amy Janine (University of Alabama Libraries, 2013)

Hierarchically porous materials are of great interest in such applications as catalysis, separations, fuel cells, and advanced batteries. One such way of producing these materials is through the process of nanocasting, in ...
Synthesis, characterization and applications of metal nanoparticles supported on porous carbon

Thambiliyagodage, Charitha Jayaruk (University of Alabama Libraries, 2017)

Porous carbon incorporating metal nanoparticles has been synthesized by nanocasting. The main two methods of synthesis were used: the formation of nanoparticles during the carbonization of carbon, and the formation of ...
The effect of fluoride on the crystallinity and photoactivity of titania

Brauer, Jonathan Isaac (University of Alabama Libraries, 2012)

This dissertation describes the synthesis and characterization of fluorinated N-doped TiO_2 nanoparticles under ambient conditions. Samples were synthesized by sol-gel methods that utilized the controlled hydrolysis of ...
The synthesis and characterization of metal chalcogenide-pedot: pss polymer composites for thermal energy conversion

Anderson, Kimberly L. (University of Alabama Libraries, 2015)

This dissertation describes the synthesis and characterization of metal chalcogenide/PEDOT:PSS polymer composites as possible thermoelectric materials for thermal energy conversion; specifically, Te, Bi2Te3, Bi2S3, and ...
The use of mesoporous silica as a template for the nanocasting of metal oxide arrays

Staggemeier, Katrina Ann (University of Alabama Libraries, 2015)

The mesoporous silica SBA-15 was used as a template for the formation of metal oxide nanowire arrays using the nanocasting approach. This approach utilizes solutions that fill the mesopores of the silica template with a ...
