The Effect Of Ph And Counterion On The Size Distribution And Luminescence Lifetime Of Terbium-Doped Lanthanum Nanocrystals, Sarah Baker
Undergraduate Honors Theses
In recent years, nanoparticles have been applied to and have gained prevalence in fields such as chemistry, biology, the medical sciences, and biotechnology,and have attracted the attention of medical researchers as potential microscopic drug delivery systems in the human body. In particular, nanoparticles made with the lanthanides have shown themselves to be useful to many biological applications due to their unique luminescent properties. It is crucial to determine optimum synthetic parameters so that nanoparticles are both small enough to pass through the kidneys and also have the ability to attach different functional groups so that they may be relevant to …
Isotropic Oscillator Under A Magnetic And Spatially Varying Electric Field, David L. Frost Mr., Frank Hagelberg
Isotropic Oscillator Under A Magnetic And Spatially Varying Electric Field, David L. Frost Mr., Frank Hagelberg
Undergraduate Honors Theses
We investigate the energy levels of a particle confined in the isotropic oscillator potential with a magnetic and spatially varying electric field. Here we are able to exactly solve the Schrodinger equation, using matrix methods, for the first excited states. To this end we find that the spatial gradient of the electric field acts as a magnetic field in certain circumstances. Here we present the changes in the energy levels as functions of the electric field, and other parameters.
The Analysis Of The Decomposition Of Hydrogen Peroxide Using A Schiff Base Copper Complex By Cyclic Voltammetry, Gavin James Rustin Mr.
The Analysis Of The Decomposition Of Hydrogen Peroxide Using A Schiff Base Copper Complex By Cyclic Voltammetry, Gavin James Rustin Mr.
Undergraduate Honors Theses
Copper(II) complexes of Schiff bases can be used in the catalysis of hydrogen peroxide to create water and oxygen. The mechanism and the kinetics of this disproportionation reaction by a dimeric copper(II) complex [CuSALAD]2 are studied in this experiment, where SALAD refers to a Schiff Base ligand formed from salicyaldehyde and 1S,2S-D(+)-1-phenyl-2-amino-1,3-propanediol. By using cyclic voltammetry, the oxidation-reduction processes of a reaction may be monitored. The [CuSALAD]2 is initially reacted with a base such as imidazole to form the catalytic species, and the ratio of the copper(II) complex to the imidazole was found to be 1:4, consistent with …
