The Exchange Of Antimony Between Antimony Trichloride And Antimony Pentachloride In Carbon Tetrachloride Solution, Franklin Brett Barker

Chemistry and Chemical Biology ETDs

In the investigation of any chemical reaction, the main points of interest are the conditions of equilibrium, the rate at which equilibrium is approached, and the mechanisms by which the reaction occurs. The first of these is determined by the standard free energy change, a thermodynamic quantity which depends only upon the initial and final states of the system. However, two reactions having the same value of the standard free energy change may approach equilibrium at radically different rates, one being practically instantaneous and the other almost infinitely slow. The field of chemical kinetics is concerned with the study of …

A Semi-Micro Spectrophotometric Method Of Copper Analysis, Edgar Miller Layton

Honors Theses

The Manhattan Project of the United States atomic energy program was designed essentially to produce methods and instruments of atomic warfare. Out of the many investigations made by the scientists and engineers working to attain this primary goal, much information of value was necessarily placed in the background and, as a consequence, a vast amount of material was only cursorily studied by these workers. The type of relationship between the per cent transmission and concentration decrease was to be investigated in the hope of establishing an empirical formula for use in a certain concentration range. As an added check on …

Electrodeposition And Cathode Potential, Kenneth Frederick Greenough

Honors Theses

When two electrodes are placed in a solution of an electrolyte and a voltage is applied, a continuous current will flow only when the voltage is equal to or greater than the decomposition potential of the electrolyte. At voltages above the decomposition potential, the current is proportional to the applied voltage, i.e. Ohm’s law where I = E/R. At voltages below, there is a temporary flow of current, existing until the products of electrolysis accumulate and produce an opposing voltage, causing the residual current to diminish. A plot of current versus applied voltage is at first almost horizontal, and the …

Geology Of The Ragged Point Oil Field Musselshell County, Montana, David M. Amos

Bachelors Theses and Reports, 1928 - 1970

The Ragged Point oil field is located in Northwest Musselshell County, in the Lake Basin field of central Mon­tana, and on the western border of the Great Plains region. The surface topography is that of a plain marked by erosion and moderate folding. The stratigraphy of central Montana shows periodic marine invasions from the Cordilleran trough, with normal marine limestones interbedded with sandstone sand shales. These sediments are over 12,000 feet thick, with the Creta­ceous Eagle and Colorado formations exposed at the surface on the Ragged Point anticline. Undifferentiated Cambrian lime­stones and shales are the oldest rocks encountered in drilling.

Growth And Nutrition Of Plants As Affected By Various Levels Of Exchangeable Sodium, Mohammad B. Choudhri

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In saline soils, which are characterized by an appreciable quantity of neutral soluble salts, plant growth is adversely affected due to the increase in osmotic pressure and the consequent decrease in the physiological availability of water. In addition, growth may also be restricted through the accumulation of toxic quantities of various ions within the plant.

On the other hand, alkali soils, whether saline or non-saline, are characterized by a high content of exchangeable sodium in the cation-exchange complex. One reason of low productivity on these soils is the unfavorable physical conditions induced by the dispersing action of the sodium ions. …

The Content Of Essential Amino Acids In 1950 Alfalfa Hay Grown In Utah Soil Treated With Different Fertilizers, Adriana Lanting Kunkel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Application of fertilizers to soils to increase production yields has raised questions concerning the effect of fertilizer on chemical composition of plants. With the development of accurate, sensitive microbiological methods for the determination of amino acid in protein, speculations concerning amino acid content have been supplanted by acquisition of facts.

The effect of the different fertilizer applications on alfalfa yield has been discussed by Jones, et al (5). Also, some work has been done to determine the effect different fertilizers might have on the amino acid content of plant material. Some values (1,3,12) have been reported for the amino acid …

A process of column chromatography of human erythrocyte acetylcholinesterase, using a cationic exchange resin, was investigated as a possible method for the primary partial purification of the enzyme on a large scale. The investigation was based, first; on a detailed study of the enzymatic stability to variation in hydrogen-ion and salt concentrations for periods of time extending to forty eight hours and, second; on an investigation of the degree of adsorption by the resin of the enzyme at various pH values within the pH range of enzyme stability. A method for the analysis of the enzyme activity of large numbers …

Soil Additives And Their Effect On The Yield Of Various Crops And The Physical Properties Of An Agricultural Soil, Gaylen L. Ashcroft

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is generally accepted that soil structure is very important in keeping productivity at a high level. When soils are loose and friable, mechanical impedance to root growth and seedling emergence is greatly reduced. Such soils infiltrate greater quantities of precipitation, are better aerated, and possess a more favorable temperature than puddled soils. Essential plant nutrients are also more easily available in well aggregated soil.

In the last few years, several synthetic soil additives have been placed on the market. Extravagant claims have been made about the ability of these amendments to maintain soil structure, without a sound body of …

The Synthesis Of 10-Methyl-3, 4-Benzpyrene And 8,10-Dimethyl-3, 4-Benzpyrene, Jules Adelfang

Chemistry and Chemical Biology ETDs

In 1953 Cook, Hewett, and Rieger found a highly carcinogenic hydrocarbon in coal tar. By a variety of solvent extraction methods, fractional distillation, and crystallization several pure hydrocarbons were isolated from the crude pitch. Two new pentacyclic aromatic hydrocarbons were isolated and since only small quantities of them were available it was decided to ascertain their structures by synthesis instead of degradetive experiments. The hydrocarbon samples were obtained with great difficulty from two tons of crude pitch. The problem was simplified since ten of the possible fifteen pentacyclic hydrocarbons were known. From certain similarities of these hydrocarbons to perylene its …
