Investigation of the relationships between laser energy and vaporized target material, continuum intensity, and plume energy in laser plume spectroscopy

Creator:: Flugstad, Paul Morris
Abstract:: A focused Q-switched neodymium-doped glass laser with power levels ranging from 1-6 MW and with a 50-nsec halfwidth, was used to vaporize copper metal. Experimental measurements showed that the amount of material vaporized away from the target was not linear with laser power and was much less than could be...

Heats of immersion and swelling of quaternary ammonium complexes of montmorillonites

Creator:: St. Clair, Akos Dominic
Abstract:: Heats of immersion were obtained for four different organophilic clay complexes in a series of normal alcohol-heptane mixtures with alcohols of increasing chain length. The immersion calorimeter employed was the Dewar type with a sensitivity of approximately 5 x 10⁻⁵°C. Gel volumes were determined for two of the clay complexes...

CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

Creator:: Loughran, Ryan P.
Abstract:: We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

Large volume (1,800 µL) injection HPLC/MS/MS for the quantitative determination of illicit drugs and human urinary biomarkers in municipal wastewater

Creator:: Chiaia Hernandez, Aurea C.
Abstract:: A sensitive, selective, rapid analytical method based on large-volume injection (LVI) liquid chromatography/ tandem mass spectrometry was developed using commercially-available hardware that eliminates the need for either off-line or on-line solid phase extraction. Centrifugation followed by the direct injection of 1,800 µL was used for the quantification of illicit drugs,...

A critical comparison of methods for the determination of phytoplankton chlorophyll

Creator:: Salinas, John T.
Abstract:: The concentration of chlorophyll in natural bodies of water is commonly determined as a means to rapidly estimate the phytoplankton biomass. The literature gives numerous warnings, however, as to the problems involved with accurately determining chlorophyll concentrations. The author's work at Crater Lake, Oregon enticed him to explore critically the...

Analytical methods for the study of migration of chloride ions in reinforced concrete under cathodic protection

Creator:: Orlova, Nadejda V.
Abstract:: The migration of chloride ions in concrete with steel reinforcement under cathodic protection was investigated. Mortar blocks (15 cm x 15 cm x 17 cm) of various composition (water to cement ratio, chloride ion content) were cast with an iron mesh cathode embedded along one face and a thermally sprayed...

A method for investigation of selective adsorption from binary vapor mixtures

Creator:: Stoner, John Thomas
Abstract:: An apparatus and procedure are described for investigating selective adsorption from a binary vapor mixture as a function of pressure. The technique measures both total mass adsorption and adsorbed-phase composition. Development of the method is outlined. Possible sources of error are analyzed and are found to be either nonexistent or...

Theoretical study of beryllium borohydride Be(BH₄)₂

Creator:: Alghamdi, Maha D.
Abstract:: Ab initio calculations using the B3LYP and CCSD(T) methods were employed in this work to explore the most stable structure of the intriguing compound Be(BH₄)₂, for which as many as seven different structures have been proposed in the literature. Use of the B3LYP density functional method with several large basis...

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...
