LBL-11031 STRIPPING OF PROCESS CONDENSATES FROM SOLID FUEL CONVERSION Joel David Hill (M.S. thesis) TWO-WEEK LOAN COPY This is a Library Circulating Copy June 1980 which may be borrowed for two weeks. Prepared for the U.S. Department of Energy under Contract W-7405-ENG-48
The preliminary goal of this study is to determine the effects of processing conditions, compositions and microstructural morphologies of the constituents on the physical and thermo-mechanical properties of alumina (Al_2O_3) reinforced aluminum (Al) composites. Composites with 0, 5, 10, 20 and 25 vol% Al_2O_3 were man…
It is shown that adsorption energy at semiconductor surfaces critically depends on the charge transfer to or from the adsorbed species. For the processes without the charge transfer, such as molecular adsorption of closed shell systems, the adsorption energy is determined by the bonding only. In the case involving cha…
The cumulative phase shift observed in the time-domain reflectivity oscillations was erroneously attributed to an increase in the real part of the refractive index of the diamond specimens in the region of implantation damage, and should instead be attributed to a decrease in the real index.Subsequent analysis has rev…
A major challenge in single particle reconstruction methods using cryo-electron microscopy is to attain a resolution sufficient to interpret fine details in three-dimensional (3D) macromolecular structures. Obtaining high resolution 3D reconstructions is difficult due to unknown orientations and positions of the image…

Copper based catalysts are of importance to a number of industrial processes including the synthesis of methanol, the reduction and decomposition of nitrogen oxides, and treatment of waste water. In copper catalysis surface oxidation and oxidic overlayers are believed to play a crucial role. In this work using density…
Nucleotidylyltransferase inhibitors are designed to target enzymes responsible for one step of cell wall biosynthesis in Gram-positive, Gram-negative and mycobacteria. Glucose 1-phosphate thymidylyltransferase Cps2L/RmlA (EC 2.7.7.24) is an enzyme essential for the growth and proliferation of many bacteria, including…
Piezoelectric bimorph based on k 32 mode of ternary 0.24Pb(In 1/2 Nb 1/2 )O 3 –0.46Pb(Mg 1/3 Nb 2/3 )O 3 –0.30PbTiO 3 (0.24PIN–‐0.46PMN–‐0.30PT) single crystal poled along [011] c has been fabricated and tested. The bimorph features very large electromechanical coupling factor (0.80) and very low working frequency (le…
SiC stability and recession rates were modeled in hydrogen/oxygen combustion environments for the Integrated High Payoff Rocket Propulsion Technology (IHPRPT) program. The IHPRPT program is a government and industry program to improve U.S. rocket propulsion systems. Within this program SiC-based ceramic matrix composi…
This report presents a variety of experimental studies on the polyurethane foam, BX-265. This foam is used as a close-out foam insulation on the space shuttle external tank. The purpose of this work is to provide a better understanding of the foam s behavior and to support advanced modeling efforts. The following expe…
The unique electronic properties and high surface-to-volume ratios of single-walled carbon nanotubes (SWNT) and semiconductor nanowires (NW) 1-4 make them good candidates for high sensitivity biosensors. When a charged molecule binds to such a sensor surface, it alters the carrier density5 in the sensor, resulting in…
Predicting the macroscopic response of heterogeneous materials has been the subject of extensive research in the engineering community, even more so, in the composites guild. With analytical solutions being almost impossible to obtain for such open ended problems, and numerical techniques being computationally expensi…
Lithium-ion batteries are currently widely used in electronics, electrical vehicles and other devices/machines. Along with the mounting demand for much improved performance in these developing technological fields, silicon was recognized to possess much higher energy capacity when used as an anode than graphite that i…
Metal nanoparticles exhibit, on account of their localized surface plasmon oscillations, strong tunable absorption and scattering resonances and surface-enhanced electric fields. These resonances and near-fields can be enhanced and engineered further by coupling metal nanoparticles into defined groupings or assemblies. I…

The process of drug discovery and development involves many stages including drug design, in vitro studies of drug candidate metabolism, evaluation of potential toxicity of drugs and their metabolites, and determination of protein binding and in vivo pharmacokinetics (PK) with animal models. Most of these steps are ve…
Two new metal coordination polymers, {[Ni(bda)(L1)(H2O)2] ·2H2O}n (1) and {[Ni2(bda)2(bib)2]·H2O}n (2) [H2bda = benzophenone -2,4 -dicarboxylic acid, L1 = 1,4-bis (imidazol-1-yl)benzene and L2 = 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene] have been successfully synthesized and structure characterized by IR, elemental…
A 43-year-old man was struck in the left orbit with his board while surfing and sustained a 3-cm laceration above his left eyebrow. The laceration was sutured closed primarily at a local emergency room. When he presented to UCSD oculoplastics for suture removal, he complained of diplopia with upgaze and was found to h…
A44-year-old Moroccan man had sudden onset of speech disturbance, vertiginous sensation, confusion, emesis, and altered mental status. There was no history of fever, trauma, or any major systemic illness. His general and systemic examination was unremarkable. On neurological examination, the patient was oriented to ti…
