Low-pressure appraoch to the formation and study of exciplex systems. [VPI and SU, Blacksburg, Virginia]

Description: Studies on the formation and properties of new materials for high-energy, gas-phase lasers are described. Attention is directed mainly to systems having bound excited states but unbound ground states. An important class of such excimer/exciplex systems has a van der Waals dimer/oligomer as its ground state. This research attempts to probe the relative rates of electron pumping of excited-state manifolds and the preferentially pumped vibronic states within each manifold. Reactive quenching of em… more

Restoring Sustainable Forests on Appalachian Mined Lands for Wood Products, Renewable Energy, Carbon Sequestration, and Other Ecosystems Services Quarterly Report

Description: The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. We are currently estimating the acreage of lands in VA, WV, KY, OH, and PA mined under SMCRA and reclaimed to non-forested post-mining land uses that are not currently under active management, and therefore can be considered as availab… more

CROSSCUTTING TECHNOLOGY DEVELOPMENT AT THE CENTER FOR ADVANCED SEPARATION TECHNOLOGIES

Description: The U.S. is the largest producer of mining products in the world. In 1999, U.S. mining operations produced $66.7 billion worth of raw materials that contributed a total of $533 billion to the nation's wealth. Despite these contributions, the mining industry has not been well supported with research and development funds as compared to mining industries in other countries. To overcome this problem, the Center for Advanced Separation Technologies (CAST) was established to develop technologies tha… more

Heat transfer in oscillatory flow: Final report

Description: This is the final report on a 4-year research effort funded by DOE. The bulk of the material has been included in numerous publications which are listed in a later section. Most of these have appeared already in archival journals. The most recent work is included in two Ph.D. dissertations. Since most of the material is already documented in detail in the publications mentioned above, we confine the discussion here to highlights of the results.

Engineering Development of Advanced Physical Fine Coal Cleaning Technologies: Froth Flotation. Quarterly Technical Progress Report No. 19, April 1, 1993--June 30, 1993

Description: The first system to test in the advanced DOE POC was the grinding circuit. The grinding circuit consists of the mill classifying cyclones in reverse closed circuit with the ball mill. Reverse closed circuit means the incoming feed and ball mill product are sized in the mill classifying cyclones ahead of the ball mill. This permits removal of natural-sized material and ground-sized material before recirculation through the ball mill. Numerous tests were conducted to establish the correct combina… more
