The Synthesis Of Novel Macrocyclic Multidentate Compounds From Dioxodioic Acids (1), R. Elliott Asay

Theses and Dissertations

A series of novel macrocyclic multidentate crown compounds have been prepared from a series of dioxodioic acids. The dioxodioic acids were prepared by treating various oligoethylene glycols or amines with maleic, succinic, citraconic, and glutaric anhydrides. The crown compounds were then synthesized from the dioxodioic acid chlorides obtained from the diacids and various oligoethylene glycols or ethylene diamine.

The Dependence Of The Apparent Pk Of Ion Exchange Celluloses Of Ionic Strength, Paul Cyril Gillespie

Theses and Dissertations

Diethylaminoethyl cellulose was titrated with acid and base in various concentrations of NaCl. The pK values were determined from titration curves using a graphical technique. Two titratable groups were observed from the acid titration curve, a major and a minor group. The minor group, which represented 20% of the acid titration, was barely detectable in the base titration curve and had a salt-independent pK of 6.0. The pK of the major group was strongly salt-dependent and was approximately a linear function of log N NaCl. An equilibrium shift caused by the counter ion may explain the salt dependence. Hydrogen bonding …

Quantitative Analysis Of Thin Films By Dc Arc Optical Emission Spectroscopy, Arnold W. Hogrefe

Retrospective Theses and Dissertations

The use of DC arc optical emission spectroscopy (OES) for quantitative analysis of thin films deposited on graphite electrodes was investigated as a process control tool. Three binary systems were evaluated: nickel-chromium, phosphorous-silicon, and silicon-aluminum. Sampling by direct deposition onto graphite electrodes placed in the deposition chamber with product runs proved to be a rapid, representative, and non-disruptive technique. Standard electrodes were prepared for each system either by evaporation of solutions of known concentration onto the tips of electrodes or by weighing out powdered standards of the appropriate concentrations. Standard curves were then prepared by burning multiple sets of standard …

Isoviscosity Curves In The Analysis Of The Pressure--Temperature Dependence Of Liquid Viscosity., Gayle Nathaniel King

University of the Pacific Theses and Dissertations

The temperature and pressure dependence of liquid viscosity has been extensively discussed in the chemistry, physics, and engineering literature for over half a century. Thus far, theoretical ab initio calculations of temperature and pressure effects on viscosity have been unsuccessful. Therefore there have been numerous attempts to relate fundamental properties of liquid state models with experimental viscosity, temperature, pressure, and density (η,T, P, ρ) data. This work has resulted in many semi-empirical equations expressing η as functions of temperature, pressure, volume, density, chain length, molecular weight, degrees of freedom, etc.

The Effects Of Ultrasonic Vibration, Tension And Torsion On The Charge Acceptance Of The Alkaline Silver Electrode ; Ii. Potentiostatic Studies Of The Oxide Growth Rate Law For The Alkaline Silver Electrode ; Iii. The Determination Of Ionic Transport In Silver Oxide Using Radiotracer Techniques With Ag[Superscript 110m], Reed Harold Chase

Theses and Dissertations

The effect of ultrasonic vibration on the anodic oxidation of silver foil in KOH was studied. An increase in charging capacity of approximately 20% was found to be the result of cavitation erosion. Silver wire was exposed to tension and torsion during oxidation but no change in charge acceptance was caused by these stresses. The oxide growth rate on silver foil electrodes was compared to rate equations that have been proposed for other metals. Uhlig's equations for the growth of semiconductor oxides was found to describe most of the data. The data did not fit other rate equations. Determination of …

A Review Of The Limnology Of And Water Quality Standards For Lake Mead, Charles R. Goldman

Publications (WR)

1. The waters of Las Vegas Bay, a heavily utilized recreational resource, receive discharges from a variety of municipal and industrial waste sources. The U.S. Environmental Protection Agency has determined, on the basis of numerous studies, that the present water quality violates state and federal standards and constitutes a public nuisance. Consultants have advised the Sewage and Wastewater Advisory Committee that rapid abatement of the alleged pollution conditions can be achieved by an advanced wastewater treatment (AWT) plant.

2. The major problems in Las Vegas Bay are an objectionable water color, excessive turbidity, noxious odors, and oxygen depletion in certain …

The Chemistry Of Chromium (Vi) And Chromium (V) Oxide Fluorides, Patrick Jay Green

Dissertations and Theses

New preparative routes to chromyl fluoride were sought. It was found that chlorine monofluoride reacts with chromium trioxide and chromyl chloride to produce chromyl fluoride. Attempts were made to define a mechanism for the reaction of ClF and Cr0₃ in light of by-products observed and previous investigations. Carbonyl fluoride and chromium trioxide react to form chromyl fluoride and carbon dioxide. A mechanism was also proposed for this reaction. Chromium trioxide with MoF₆ or WF₆ reacts to produce chromyl fluoride and the respective oxide tetrafluoride.

Here Is Where We Are, M. H. Baker

Journal of the Minnesota Academy of Science

Industrial chemistry in the Upper Midwest consists principally of compounding, formulating and specialty manufacturing rather than the production of basic chemicals. The economic position of industrial chemistry is, nevertheless, significant because many of the region's major corporations are employers of technically-trained personnel and are substantial chemical users. This paper provides a non-quantitative overview of chemical technology applications and developments in some of the area's key industries as a record of the past, a measure of current activity, and as a possible indicator for the future. The paper also notes that the large investment demands, complexity of regulations and distance from …

Experimental Testing Program In Elementary Chemistry: A Preliminary Report, Billie G. Broach, Howard L. Hodges

Journal of the Arkansas Academy of Science

An experimental testing program is described which utilizes questions that are partly computer composed, in addition to a section composed by the instructor, and a retesting option to the student. Results from a trial of the program for one term indicate that (1) course grades were improved, (2) the student withdrawal failure rate was unaffected, and (3) the employed students took greater advantage of the retest than did the unemployed students.

The Internal Chemical Shift - A Key To Bonding In Aromatic Molecules. 2. Substituent Effects On The Carbon-13 Magnetic Resonance Spectra Of The 1,4-Disubstituted Benzenes, Donald W. Beistel, W. Dan Edwards

Chemistry Faculty Research & Creative Works

Carbon-13 magnetic resonance shifts were determined for six families of 1,4-disubstituted benzenes. Linear least-squares correlations between the internal shifts of the families suggest an additivity relationship for 13C substituent effects at all four nonidentical ring carbons and at the α position when one of the substituents has a central carbon. The correlation of 1H and 13C shifts for these compounds is also linear, implying that the additivity relationships derived in a previous 1H study can be generalized to 13C.

The Problem

Introduction

The traditional philosophy that a college-or a university is an exclusive institution in which only highly selected individuals receive a concentrated training in the traditional liberal arts no longer exists. In America, for instance, as early as 1870, Harvard, the colonial college with a narrow curriculum, was transformed rather rapidly into a modern university with many new subjects and the elective system (Garrett, 1949). Also, since 1642, when the first entrance requirements were instituted for American higher education, a continuing debate has developed over what constitutes a sound curriculum for education. There are those who …

The Synthesis Of New Maleimide Addition Polymer Precursors, Richard B. Brown

Chemistry & Biochemistry Theses & Dissertations

1H-2,3-dimethylpyrrolo(1,2-a) benzimidazol-l-one (27) and 1H,9H- 2,3,7,8-tetramethyl-bispyrrolo(1,2-a:6,7-a')benzodiimidazo1-1,9-dione (32) have been synthesized from dimethylmaleic anhydride and o-phenylenediamine and 1,2,4,5-tetraaminobenzene, respectively. The presence of reactive olefinic double bonds in the synthesized compounds was of interest as a site for possible addition polymerization.

The synthetic route involved, in both cases, a simple nucleophilic substitution reaction between the diamine(or tetraamine) and the anhydride to form an intermediate amide-acid-amine which rapidly cyclized to the imide amine. The final ring closure required more rigorous conditions and occurred at melt reaction temperatures.

Concentrations of Ca and Sr in aorta, …

Electrochemical Machining (Ecm) With Alternating Current, S. J. Shine

Tanzania Journal of Science

Electrochemistry has had several practical uses in industry for a long time; but one of the more recent applications is the machining of metals. Direct current ECM has been applied in industry for the last two decades. However, ECM with alternating current is still in the early stage of research and development. This paper shows that ECM with normal a.c supply is feasible and practicable if special tools are used. ECM with d.c. is first introduced to provide a better insight for the machining with a.c.

Process Control Of Activated Sludge Treatment, Phase Ii, Richard I. Kermode, Robert W. J. Brett, Joseph D. Pault Jr.

KWRRI Research Reports

Material balances on substrate and microorganisms were derived in conjunction with various mixing configurations thought to accurately describe the activated sludge process. These models include the completely mixed with bypass, plug flow, and plug flow with bypass. Two sets of kinetic mechanisms for substrate utilization and bacterial growth were employed.

A feed forward controller was designed from linear approximations of the material balances derived in the completely mixed with bypass mixing model. Utilizing frequency response methods, the controller was found essentially identical to a completely mixed modeled controller developed in a prior investigation.

Through computer simulation the controller's effectiveness was …

Gas Phase Hydrogen Bonding Infrared Studies Of Four Simple Alcohols, Lawrence John Anderson

Dissertations and Theses @ UNI

The purpose of this study was to develop methods for studying gas phase hydrogen bonding and to obtain evidence of the gas phase self association of methanol, ethanol, 2-propanol and 1-propanol. A gas sample transfer manifold was designed and constructed. The gas -1 8 -1 phase infrared spectra from 3050 cm to 3800 cm of methanol, ethanol, 2-propanol and 1-propanol were examined at low and saturated pressures at approximately 4o0 c. The measured integrated absorption areas of the methanol spectra were compared to areas calculated from results found in the literature. The areas were found to be in reasonable agreement …

Locating The St. Louis Urban Plume At 80 And 120 Km And Some Of Its Characteristics, J. F. Stampfer, J. A. Anderson

Chemistry Faculty Research & Creative Works

The feasibility of locating the urban plume of a moderately large urban area, as far as 120 km downwind, is shown. The method utilizes a single engine aircraft and aerosol instrumentation. A summary of the data obtained from 34 flights, during an 8-month period, is presented and the problems involved in interpreting the data are discussed. These difficulties include nonuniform background levels outside the plume, changing relative humidity, low wind speeds and stable atmospheric layers. The plume was characterized by concentrations of small particles (0.15 < r < 0.3 μm) ca. 1.5 times that in background air and concentrations of large particles (0.3 < r < 1.3 μm) usually greater than twice that in the background. The ratio of the concentrations of small particles to large particles in the plume was about one-half of that in the background. © 1975.

The U. S. Wind Power Program, Joseph M. Savino

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Today I would like to talk about wind energy in, basically, two parts. I would like to bring to your attention some of the developments that have occurred in the 20th century. Many of us who have gone through school in the last 25-30 years don't recall anywhere in our engineering education much information dealing with wind energy, and that may come as a surprise to you as it did to me, to learn how much has actually been done in the 20th century to develop large scale wind-driven machines. After I get through with that introduction I would like …
