The design of an easily operated dc argon plasma arc for atomic spectroscopic analysis

Creator:: Murdick, Dewey A.
Abstract:: A long path dc plasma arc operated in an atmosphere of argon is described. The arc is easily ignited and operated, and is inexpensive to use. Samples were introduced into the arc as solution aerosols. Radially resolved emission measurements are reported for calcium, copper, and hafnium. The detection limit for...

The effect of oxide impurity on the conductivity of potassium chloride

Creator:: Kouts, Daberath
Abstract:: Direct current conductivity measurements on KC1:O[superscript]= crystals were used to determine an enthalpy of 0.42 ev for the dissociation for anion-vacancy-oxide ion complex. The entropy of dissociation was found to be approximately -4x 10⁻⁴ev deg⁻¹. The intrinsic "activation" energy was found to be 1.91 ev as compared to 1.95 ev,...

Gas phase x-ray photoelectron spectroscopy of compounds containing multiply-bonded oxygen

Creator:: Smith, Steven Reid
Abstract:: A new x-ray source capable of operating at up to 80 watts has been designed and developed, and put to use with the Oregon State University Cylindrical Electrostatic Analyzer. The new source produces over four times the photoelectron intensity of its predecessor, from gaseous samples, and accommodates a wider selection...

The conductivity of lead oxide doped potassium chloride single crystals

Creator:: Knepp, Donald Jack
Abstract:: A comparison was made of the d.c. conductivity of KCI:Pb²⁺ and KCl:PbO single crystals at temperatures greater than 325°C. The energy of activation was 0.72 ev for all crystals. Lead concentration was determined by chemical, optical and electrical methods. The half band width of the UV absorption band at 273...

A chemical study of the minerals from L-6 chondritic meteorites

Creator:: Curtis, David Ballantyne
Abstract:: Major and minor minerals have been separated from three L-6 chondritic meteorites (Alfianello, Colby (Wisconsin), and Leedey). Olivine, hypersthene, diopside, feldspar, troilite, chromite, phosphate minerals, and metallic minerals were analyzed for major, minor and trace elements using instrumental neutron activation analysis and radiochemical neutron activation analysis techniques. Concentrations df the...

A study of simultaneous diffusion of Ca²⁺ and Sr²⁺ in alkali chlorides

Creator:: Machida, Hisashi
Abstract:: The simultaneous diffusion of Ca 2+ and Sr 2+ ions in purified single crystals of KC1 and NaC1 was studied over the temperature ranges from 451°C to 669°C in KC1 and from 448°C to 683°C in NaCl. A radioactive tracer technique was used in two types of measurements: diffusion from...

Thermal [pi]-route rearrangement of 4-cycloheptane-1-methyl acetate

Creator:: Schick, Lawrence Edward
Abstract:: Pyrolysis of 4-cycloheptene-l-methyl acetate under flow conditions at 285° gives only rearranged bicyclic acetates and hydrocarbons rather than the anticipated simple elimination product methylenecyclohept- 4-ene. These rearranged acetates have the same structures and are formed in virtually the same relative percentages as those observed in the "π- route" solvolysis of...

The reaction between O-ions and F centers

Creator:: Staible, Thomas Fredrick
Abstract:: The photochemical reaction between O⁻ ions and F centers was investigated. The activation energy was determined by the Arrhenius law to be 0.10 + 0.04 eV for temperature below 180°K. The diffusion of alpha centers towards the oxide ion was eliminated as the rate limiting step and the low trapping...
