High pressure HC1 conversion of cellulose to glucose

Description: The production of ethanol from glucose by means of fermentation represents a potential long-range alternative to oil for use as a transportation fuel. Today's rising oil prices and the dwindling world supply of oil have made other fuels, such as ethanol, attractive alternatives. It has been shown that automobiles can operate, with minor alterations, on a 10% ethanol-gasoline mixture popularly known as gasohol. Wood has long been known as a potential source of glucose. Glucose may be obtained fr… more

Investigation of the validity of the OZI rule and study of production properties of the anti K*/sup. / resonance in. pi. /sup +/p interactions at 16 GeV/c

Description: Results are reported from a streamer chamber experiment performed at Stanford Linear Accelerator Center (SLAC) to study the production of the phi (1020) in OZI-allowed and forbidden processes in ..pi../sup +/p interactions at 16 GeV/c. Production properties of the anti K*/sup ./(896) are also studied and discussed.

Mass-spectrometric determination of trace elements in aqueous media without preconcentration

Description: Feasibility of using a low pressure glow discharge as an ion source for the mass spectrometric determination of trace elements in aqueous media was investigated. A cryogenically cooled hollow cathode ion source was developed to analyze aqueous samples without external preconcentration. Aqueous solutions containing seventy elements were analyzed and the detection limits, sensitivity factors, and linear regression correlation coefficients were determined. A standard test solution of trace element… more

Production of chi mesons in 225 GeV/c. pi. /sup -/Be interactions

Description: Gamma rays associated with psi mesons have been studied in 225 GeV/c ..pi../sup -/Be interactions. The psi-..gamma.. mass spectrum shows an excess of 47 +- 11 events above background centered at 3.531 GeV/c/sup 2/ with an rms width of 22.4 MeV. Attributing this excess of events to the decay chi ..-->.. psi ..gamma.. implies that 38 +- 9 % of all psi mesons are produced by this mechanism. The experimental setup and results are detailed.

Influence of lead ions on the macromorphology of electrodeposited zinc

Description: The morphology of zinc as it is electrodeposited from acid solutions demonstrates a remarkable imprint of electrolyte flow conditions. The development of macromorphology of zinc deposits has been investigated under galvanostatic conditions on a rotating plantinum disk electrode by use of photomacrography, scanning electron microscopy, electron probe microanalysis and Auger microprobe analysis. Logarithmic spiral markings, which reflect the hydrodynamic flow on a rotating disk, appear in a certa… more

Soft x-ray streak camera for laser fusion applications

Description: This thesis reviews the development and significance of the soft x-ray streak camera (SXRSC) in the context of inertial confinement fusion energy development. A brief introduction of laser fusion and laser fusion diagnostics is presented. The need for a soft x-ray streak camera as a laser fusion diagnostic is shown. Basic x-ray streak camera characteristics, design, and operation are reviewed. The SXRSC design criteria, the requirement for a subkilovolt x-ray transmitting window, and the result… more
