X-ray structure studies of oriented phospholipid multilayers

Creator:: Lytz, Robert Keith
Abstract:: Lamellar x-ray diffraction was studied from thin films of L-α-1,2-dipalmitoyl lecithin (DPL) and a 1:1 mixture (BrDPL) of L-α-l-palmitoyl-2-(9- bromopaimitoyl) lecithin and its 10-bromo analog. The specimens had high lamellar order, with an upper bound on the mosaicity of 6 mrad (0.4°) for DPL and BrDPL. With various water contents,...

Water and methanol adsorption on a series of organic complexes of montmorillonite

Creator:: Carter, Loren Sheldon
Abstract:: Water and methanol adsorption isotherms at 25° and 37° C. were determined on a series of organo-bentonite clays. The clays differed in the length of the carbon chain attached to the amine adsorbed in the cation exchange position. The amines used had carbon chains of 4, 6, 8, 10, 12,...

Vibrational spectroscopy of hydrogen bonded species

Creator:: Hopkins, Glen A.
Abstract:: Due to its importance, the phenomenon of hydrogen bonding has been the subject of much research over the years. Among the different techniques used to study hydrogen bonded systems, vibrational spectroscopy is perhaps the most sensitive because of the striking changes induced in molecular spectra by the formation of hydrogen...

Variations in trace element abundances in small fragments from a single terrestrial basaltic flow : applications to 59 Apollo-17 mare basaltic fragments

Creator:: Rivera, Maria Rita Dacanay
Abstract:: Eleven hand specimen whole rock (WR) samples (25-200 g each) and 33 fragments (0.5-0.8 g each) from a single basaltic flow at Picture Gorge, Oregon were analyzed via instrumental neutron activation analysis (INAA) for 12 elements (Na, Fe, Cr, Sc, Co, La, Sm, Eu, Yb, Lu, Hf and Ta). Standard...

Trans-Pacific and regional atmospheric transport of anthropogenic semivolatile organic compounds in the western U.S.

Creator:: Primbs, Toby
Abstract:: The atmospheric transport of anthropogenic semivolatile organic compounds (SOCs) from Asian sources to the Western U.S. was investigated. In addition, the SOC extraction method was optimized. Hansen solubility parameter plots were used to aid in the pressurized liquid extraction (PLE) solvent selection of air sampling media in order to minimize...

Theory of negative thermal expansion

Creator:: Tao, Ju Zhou
Abstract:: Two framework oxide materials of the MO₃ network type have been synthesized and structurally characterized by synchrotron and X-ray powder diffraction and the Rietveld method in the temperature range 25~500 K. The results show one of them to be a low thermal expansion material. Theoretical studies of negative thermal expansion...

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...
