Carbonic Acid Pretreatment of Biomass

Description: This project sought to address six objectives, outlined below. The objectives were met through the completion of ten tasks. 1) Solidify the theoretical understanding of the binary CO2/H2O system at reaction temperatures and pressures. The thermodynamics of pH prediction have been improved to include a more rigorous treatment of non-ideal gas phases. However it was found that experimental attempts to confirm theoretical pH predictions were still off by a factor of about 1.8 pH units. Arrhenius e… more

Biochemistry of Dissimilatory Sulfur Oxidation

Description: The long term goals of this research were to define the substrate oxidation pathways, the electron transport mechanisms, and the modes of energy conservation employed during the dissimilatory oxidation of sulfur practiced by various species of the thiobacilli. Specific adhesion of the thiobacilli to elemental sulfur was studied by electrical impedance, dynamic light scattering, laser Doppler velocimetry, and optical trapping methods. The conclusion is that the thiobacilli appear to express spec… more

Bioenergy Crop Breeding and Production Research in the Southeast, Final Report for 1996 to 2001

Description: Switchgrass (Panicum virgatum L.) is a native grass species to much of the US. It has shown great potential for use in production of fuel ethanol from cellulosic biomass (Lynd et al., 1991). Work in Alabama demonstrated very high dry matter yields can be achieved with switchgrass (Maposse et al. 1995) in the southeastern US. Therefore, this region is thought to be an excellent choice for development of a switchgrass cropping system where farmers can produce the grass for either biomass or forag… more

Electronic Banking: The Check Truncation Issue

Description: If all checks were replaced by electronic transactions, the exact cost savings would still be unknown, because estimates of the cost of using a check and the number of checks written each year remain in dispute. Consequently, estimates of cost savings range from $1.4 billion annually for truncation alone to $68 billion for replacing checks with electronic payments. A significant part of the savings comes from eliminating the handling, sorting, and physically transporting of checks to the paying… more

Environmental Streamlining Provisions in the Transportation Equity Act for the 21st Century: Status of Implementation

Description: At the state and local level, many observers have expressed long-standing concerns over delays, duplication of effort, and additional costs frequently associated with the environmental review process for highway projects that must be completed under the National Environmental Policy Act of 1969 (NEPA, P.L. 91-190). To address these concerns, the Transportation Equity Act for the 21st Century (TEA21, P.L. 105-178), enacted in 1998, requires the Federal Highway Administration(FHWA) to streamline … more

The Influence of MSI (Metal-Support Interactions) and the Solvent in Liquid-Phase Reactions

Description: Results were repeatedly obtained that were consistent with a hypothesis proposed at the beginning of this program, i.e., due to Metal-Support Interactions (MSI), unique active sites can be created in the metal-support interfacial region to enhance activity and improve selectivity in certain types of reactions, especially those involving the hydrogenation of carbonyl and unsaturated C=C bonds. Higher turnover frequencies (TOF-molecule/s/site) and increased selectivity for C=O bond versus C=C bon… more
