Air gun test evaluation

Description: A mechanical shock testing apparatus is used for testing the response of components subject to large accelerations in hostile environments. The test acceleration is provided by the impact of a bullet against a plate on which the component to be tested is mounted. This report describes a series of experiments that were performed to determine the dependence of the air gun test apparatus performance on incremental changes in the hardware configurations, changes in the pressure used to drive the bu… more

Electrochemical and optical studies of model photosynthetic systems

Description: The objective of this research is to obtain a better understanding of the relationship between the structural organization of photosynthetic pigments and their spectroscopic and electrochemical properties. Defined model systems were studied first. These included the least ordered (solutions) through the most highly ordered (Langmuir-Blodgett (LB) monolayers and self-assembled monolayers) systems containing BChl, BPheo, and UQ. Molecules other than the photosynthetic pigments and quinones were a… more

Enchancing the use of coals by gas reburning-sorbent injection

Description: The objective of this project is to evaluate and demonstrate a cost effective emission control technology for acid rain precursors, oxides of nitrogen (NO{sub x}) and sulfur (SO{sub x}), on two coal fired utility boilers in Illinois. The units selected are representative of pre-NSPS design practices: tangential and cyclone fired. Work on a third unit, wall fired, has been stopped because of funding limitations. The specific objectives are to demonstrate reductions of 60 percent in NO{sub x} and… more

Evaluation of gas-reburning and low NO{sub x} burners on a wall fired boiler. Technical progress report No. 5, October 1--December 31, 1991

Description: Low NO{sub x} burners operate on the principle of delayed mixing between the coal fuel and burner air, so that less NO{sub x} is formed. Gas reburning is a combustion modification technique that consists of firing 80--85 percent of the fuel corresponding to the total heat release in the lower furnace. Reduction of NO{sub x} to molecular nitrogen (N{sub 2}) is accomplished via the downstream injection of the remaining fuel requirement in the form of natural gas (which also reduces the total SO{s… more

Role of structure in ion movement of glasses

Description: Can the structure of a melt much above the glass transition temperature (Tg) determine the structure and (transport) properties of glass In other words, are there extremely long lasting configurations in a melt which would affect ion transport in the glassy state A major effort during the past year has been to address these very fundamental questions. An important consideration here is to separate the effect of the variable melt structure from that of a variable cooling rate in the glass transf… more

Studies of nuclear reaction at very low energies

Description: The deuteron radiative capture reactions on {sup 2}H, {sup 6}Li and {sup 10}B have been measured between center of mass energies of 20 and 140 keV. Of note is the observation that the gamma ray-to-charged particle branching ratio for the DD reaction appears independent of energy down to a center of mass energy of 20 keV, consistent with some and contrary to other theoretical models. We have investigated the ratio of the reactions D(d,p)T and D(d,n){sup 3}He down to c.m. energies of 3 keV and th… more
