Dielectric Constant-Temperature Relationship In Some Chlorinated Phenyl Ethers, Raymond Stuart Martin Jun 1958

Dielectric Constant-Temperature Relationship In Some Chlorinated Phenyl Ethers, Raymond Stuart Martin

Honors Theses

Dielectric liquids play an important role in the transmission, distribution, and use of electrical energy. A liquid is arbitrarily classed as a dielectric if its volume resistivity is 10(10) ohm-centimeters or greater. (An ohm-centimeter is the resistance between opposite faces of one cubic centimeter of the liquid.) Transformers, circuit breakers, cables, and capacitors are among the more common devices using liquid dielectrics. The chief electrical properties which determine the performance of a dielectric liquid are its ability to resist breakdown under electrical stress, its dielectric constant (or specific inductive capacity), and its loss factor - the energy loss per unit …

Corrosion Behavior Of Zircaloy, Alan Blair Riedinger May 1958

Corrosion Behavior Of Zircaloy, Alan Blair Riedinger

Honors Theses

Zirconium base alloys are widely used in water cooled nuclear reactors where their high cost is offset by their low neutron cross section and relatively good resistance to corrosion in water. Although the amount of corrosion is quite small, an accurate estimate of the amount to be expected is required for good reactor design. 'This estimate is made by extrapolating available data to the expected life of the reactor. For valid approximations it is necessary to know the form of this corrosion rate curve.

A New Electronic Coulometer For Electroanalytical Chemistry, Jack Donald Merry Jun 1957

A New Electronic Coulometer For Electroanalytical Chemistry, Jack Donald Merry

Honors Theses

The failure of electroanalytical chemistry to apply extensively the principles of Faraday's laws, has been due primarily to the lack of a direct reading coulometer. The author has investigated several methods of current integration and has concluded that a direct current amplifier with a feedback capacitor shows best promise as a coulometer.

Controlled Cathode Electrodeposition, Walter Adolf Stock Jun 1957

Controlled Cathode Electrodeposition, Walter Adolf Stock

Honors Theses

The purpose of this project was to gather data on electrodeposition with controlled potential, and furthermore, to establish a suitable punched-card system for the recording of such data. In the course of this project, it was discovered that the latter took precedence over the former, since it was deemed more vital to have a good punched-card system with fewer data than more data rendered difficult to refer to because of an inefficient system.

A New Apparatus For Paper Electrophoresis, Robert John Hodges Jun 1956

A New Apparatus For Paper Electrophoresis, Robert John Hodges

Honors Theses

In paper electrophoresis, taking the idealized case, a charged particle, i.e. a particle which has an excess or deficiency of electrons, resulting in a net electrostatic charge is placed on a strip of moistened filter paper. The moistening is usually done by a buffer solution which serves two purposes: 1. It provides a liquid phase within the structure of the paper through which the particle can travel. 2. It keeps a constant pH throughout the run. After experimenting with several types of apparatus the author decided that a new type of apparatus was needed and could be designed which would …

Preparation Of Several Lactams And Correlation Of Their Structure With Their Infrared Spectra, Kenneth Curtiss Heckeler Dec 1955

Preparation Of Several Lactams And Correlation Of Their Structure With Their Infrared Spectra, Kenneth Curtiss Heckeler

Honors Theses

Simple amides are neutral compounds with infrared absorptions characterized by a strong carbonyl absorption. N-H absorptions, and other less significant and unassigned absorptions. Lack of basic nature of amides has been attributed to strong resonance of the unshared pair of electrons on nitrogen with the C=O double bond. This stabilized the molecule to an extent not possible when the electron pair on nitrogen is protonated, since resonance stabilization of such an ammonium structure is no longer possible.

The Hofmann Degradation Of Oxamide And Urea, Carmen Michael Cusano Jun 1955

The Hofmann Degradation Of Oxamide And Urea, Carmen Michael Cusano

Honors Theses

An amide may be degraded to an amine using the Hofmann reaction. The theoretical product of the Hofmann reaction of oxamide is hydrazine. The objective of this project was the production of hydrazine from oxamide. Since hydrazine could not be obtained from oxamide, an extensive study was made of the production of hydrazine from urea. It was hoped that the background gained in the study of the urea reaction could be applied to the original problem, i.e. the formation of hydrazine from oxamide. However, even with this background, no hydrazine was obtained from oxamide.

Electrodeposition And Cathode Potential, Roland Francis Dapo Jun 1955

Electrodeposition And Cathode Potential, Roland Francis Dapo

Honors Theses

The objective of electrodeposition and control of cathode potential is the qualitative and quantitative separation of metals from their solutions. It involves the problem: (1) measuring the cathode potential in relation to the solution in order selectively to plate any metal; (2) means of treating the solution to prevent the plating of more than one metal at any particular cathode potential. The present research involved the curve of cathode potential versus copper concentration, the designing and constructing of electronic units for automatic control, and the determination of voltage error in passing current through the saturated calomel electrode.

A Study Of The Effect Of Additives On Portland Cement, Sidney Gray Dunbar Jun 1955

A Study Of The Effect Of Additives On Portland Cement, Sidney Gray Dunbar

Honors Theses

First, hydration tests were made on cement samples containing various percentages of Sodium Methyl Siliconate and Sodium Silicate. It was decided that it would be easier to determine what effect an additive would have upon concrete, if concrete blocks were actually made. Therefore, many blocks were made containing different amounts of various additives. Some of the concrete blocks were cut into cubes and slabs. The cubes were tested for their compressive strength. The slabs were tested for their resistance to corrosion from hydrochloric, acetic, and lactic acids. Some slabs were coated with certain substances to see if the coatings would …

Thermal And Arc Resistance Of Polyester Resin Glass Reinforced Laminates, Frederick B. Budnik Jun 1955

Thermal And Arc Resistance Of Polyester Resin Glass Reinforced Laminates, Frederick B. Budnik

Honors Theses

The heat resistance of several types of polyester resins are studied by measuring the flexural strength of glass reinforced laminates before and after conditioning at 200°C. Arc resistance readings are also taken. The type of saturated acid, glycol and monomer is varied. The ratio of saturated to unsaturated acid and the ratio of monomer to base resin is also studied. Chlorendic acid improves the heat resistance over phthalic and isophthalic acids but it lowers the arc resistance. Ethylene glycol yields resins with the highest flexural strengths. Styrene monomer content has little effect on heat resistance up to 40%. In the …

Preparation, Purification And Cis-Trans Isomerization Of 2-Butene-1, 4-Diol, Roman Stephan Slysh May 1955

Preparation, Purification And Cis-Trans Isomerization Of 2-Butene-1, 4-Diol, Roman Stephan Slysh

Honors Theses

The preparation of cis- and trans-2-butene-1,4-diol has been reported in chemical literature by numerous workers. A well established procedure to obtain the cis isomer is to hydrogenate 2-butyne-1,4-diol at two to four atmospheres pressure in the presence of catalysts, such as Raney nickel or colloidal palladium. This reduction is selective and can be stopped easily at the ethylenic stage. The reaction has been studied by Lozac'h who stated that the Raman spectrum of 2-butene-1,4-diol prepared in this way indicates the presence of the cis iomer only. Lozac'h does not mention the degree of purity of this product and nothing could …

A Semi-Micro Spectrophotometric Method Of Copper Analysis, Edgar Miller Layton Jun 1954

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 Jun 1954

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 …
