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 …
Studies On The Manganese Cycle, Jim Gilbert
Studies On The Manganese Cycle, Jim Gilbert
Honors Theses
The first studies on the manganese cycle in impoundments were concerned with the manganese concentrations in and removal from bottom waters of deep impoundments. But as work progressed, the emphasis was more on the investigation of the mechanism by which manganese is dissolved in impounded waters.
