Comparison Of Stirred And Immobilized Cell Reactors For Ethanol Production, Oliver C. Sitton, J. L. Gaddy

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Biomass can be converted to sugars by hydrolysis with enzymes or mineral acids. These sugars can be converted into a number of chemical intermediates in biological reactors. Biological reactions are generally slow and selection of the most efficient reactor is important in these applications.

Immobilized cell reactors allow high cell densities and high throughput by attaching microorganisms to a fixed support. This paper compares the rate of production of ethanol from glucose by Saccharomyces Cerevisiae in a packed column and a stirred reactor.

Continuous stirred reactor studies showed a washout rate of .27 hr^-1. The optimum rate of …

The Formation And Decomposition Of Nickel Carbide In Evaporated Nickel Films On Graphite, S. Sinharoy, L. L. Levenson

Physics Faculty Research & Creative Works

Auger electron spectroscopy and X-ray photoelectron spectroscopy were used to study nickel carbide (Ni3C) formed during the evaporation of nickel onto the surface of single-crystal graphite. It is shown that Ni3C formed in this manner extends from the surface to close to the interface. A model is proposed to explain the mechanism of Ni3C formation. The 1s photoelectron peak from Ni3C is observed to have a binding energy 0.6 eV lower than that of pure graphite. This is attributed to the lack of any significant ionic bonding in Ni3C. © 1978.

Webs For Cold Formed Steel Flexural Members Structural Behavior Of Transversely Reinforced Beam Webs, Wei-Wen Yu, Nguyen Phung

CCFSS Library (1939 - present)

Since 1973, a research project on webs for cold-formed steel flexural members has been conducted at the University of Missouri-Rolla under the sponsorship of American Iron and Steel Institute. This study deals with the structural behavior of beam webs subjected to bending stress, shear stress, combined bending and shear, web crippling and the effect of bending on web crippling load. In addition, it includes a study of beam webs reinforced by either transverse or longitudinal stiffeners. This report presents the research findings on transversely reinforced cold-formed steel beam webs. The results obtained from the study of beam webs subjected to …

Angular Differential Cross Sections For 25-, 50-, And 100-Kev-Proton Excitation Of Helium To The N=2 Level, John T. Park, Jacob M. George, Jerry Peacher, John E. Aldag

Physics Faculty Research & Creative Works

Differential cross sections for 25-, 50-, and 100-keV-proton excitation of helium to the n=2 level have been determined for center-of-mass scattering angles from 0 to 1.2 mrad. The cross sections were obtained from an analysis of the angular distribution of the scattered protons which had lost an energy corresponding to the excitation of the helium target to its n=2 level. The differential cross section is very sharply peaked in the forward direction and decreases by a factor of 45 in 1.0 mrad at 25 keV and by a factor of 650 in 1.0 mrad at 100 keV. The data are …

Thermodynamics Of The Lanthanide Trifluorides. I. The Heat Capacity Of Lanthanum Trifluoride, Laf₃ From 5 To 350°K And Enthalpies From 298 To 1477°K, William G. Lyon, Darrell W. Osborne, Howard E. Flotow, Fernande Grandjean, Ward N. Hubbard, Gerald K. Johnson

Chemistry Faculty Research & Creative Works

The heat capacity of a sample of LaF₃ was determined in the temperature range 5-350°K by aneroid adiabatic calorimetry and the enthalpy from 298.15 to 1477°K by drop calorimetry. The heat capacity at constant pressure C°_p(298.15°K), the entropy S°(298.15°K), the enthalpy [H°(298.15°K)-H°(0)] and the Planck function -[G°(298.15°K)-H°(0)]/298.15°K; were found to be (90.29±0.09) J °K^-1·mole^-1, (106.98±0.11) J °K^-1·mole^-1, (16717±17) J mole^-1, and (50.91±0.05) J °K ^-1·mole^-1. The thermal functions from the present research were extended up to the melting temperature (1766°K) by combination with previously …
