A Preliminary Study On The Separation Of Bovine Plasma Albumin-Copper Ion Dimer And Trimer Reaction Products By Ion-Exchange Chromatography, James T. Miller

Honors Theses

When bovine plasma albumin is in the presence of copper metal ions at pH values below the isoelectric point, a dimerization reaction takes place between the protein molecules. The kinetics of this reaction have been previously studied by using light scattering techniques. These techniques involve monitoring the amount of light scattered as the dimerization reaction proceeds. As the amount of dimer present increases, more light is scattered due to increased molecular size in the solution. Accurate calculations of the rate of this reaction depend upon knowing the ratio of dimer to monomer concentrations at any given time. Unfortunately, evidence has …

A Study Of Dislocations In Crystals Using The Technique Of Chemical Etching, Ramona R. Dennis

Honors Theses

The beauty of many of the crystalline solids has attracted man's attention from the earliest times. Eventually the science of crystallography developed from studies of their shapes. The word crystal sterns from the Greek word "krystallos" meaning "clear ice." The word was first applied to describe the clear quartz crystals found in the Swiss Alps. The crystals were thought to be formed from water under conditions of extreme cold.

The earliest recorded crystallographic observation was in 1597 by Andreas Libarius. He noticed that crystals of different substances often have characteristic shapes. He suggested that the salts in mineral water could …
