The purpose of the present program is to develop soluble analogs of surface confined catalysts that can be impregnated directly into the coal structure at low temperatures. This approach should avoid problems related to surface area dependence, a two phase (surface-liquid) reaction system and, mass transport limitations. Heteropolyanions (HPAs) offer the opportunity to develop soluble forms of surface confined catalysts. HPAS, are inexpensive, well-characterized, water soluble metal oxide clusters, e.g. [EM{sub 12}O{sub 40}]{sup 4-} where E = Si or P and M = Mo or W. They are easily modified to contain other transition metals such as Co, Ni or Ru and, can be made soluble in organic solvents. The protic forms exhibit extremely high acidities pK{sub a} {approx} = 0--2. In addition, selectively modified HPAs can function as low temperature hydrogenation catalysts that exhibit microporosity. HPAs are multi-functional catalysts that could be used to promote both hydroliquefaction and hydrotreating. In theory, these functions could be employed sequentially or simultaneously and could permit exceptional control of liquefaction reactions and reaction conditions. Thus, the current research program involves efforts to evaluate HPAs as soluble liquefaction and hydrotreating catalysts, with the goal of developing soluble analogs of surface confined catalysts.

High power and radiance copper-vapor laser technology developed at Lawrence Livermore National Laboratory shows great promise for many materials processing tasks. The authors recently transmitted the visible light produced by these lasers through fiber optics to perform hole drilling experiments. They found the tolerances on the hole circulatory and cylindricity to be excellent when compared to that produced by conventional optics. This technique lends itself to many applications that are difficult to perform when using conventional optics, including robotic manipulation and hole drilling in non-symmetric parts.

A closure and postclosure plan for the Hanford Site Nonradioactive Dangerous Waste Landfill (NRDWL) was prepared by Westinghouse Hanford Company (WHC) and submitted for regulatory agency review in 1990. In the closure plan, construction of a final cover over the NRDWL is proposed. The design specifies a topsoil component consisting of layers of compacted and noncompacted fine-textured soil. The objective of compacting a portion of the topsoil layer is to impede infiltration of soil moisture. The McGee Ranch area on the Hanford Site is proposed as the source area for fine-textured soils to support cover construction. A number of data needs are identified in the closure plan for definitive design of the NRDWL final cover. Specifically, the plan identifies a need to characterize potential borrow areas for fine-textured soil, to ensure that (1) material properties vary within acceptable limits for the application, and (2) sufficient quantities of suitable material are available.

The Nijmegen YN potential models are reviewed. Differences with the models constructed by the Juelich group are highlighted. A mini- review is given of the status of the scalar mesons and their relevance for the NN and YN interactions. Finally, the reactions {bar N}N {yields} {bar Y}Y are discussed.

The Notre Dame Radiation Laboratory is a facility of the Department of Energy operated for the DOE by the University of Notre Dame under contract No. DE-AC02-76ER00038. This quarterly report summarizes the progress on the programs within the Laboratory for the period of October 1, 193 through December 31, 1993. The activities of the staff during this period are noted. A list of publications is presented. A listing and a brief description of each of the reports issued during this quarter are provided.

The authors present a recursive diagrammatic method for evaluating tree-level Feynman diagrams involving multi-fermions which interact through gauge bosons (gluons or photons). Based on this method, a package called COMPUTE, which can generate and calculate all the possible Feynman diagrams for exclusive processes in perturbative QCD, has been developed (available in both Mathematics and Maple). As an example, a calculation of the nucleon Compton scattering amplitude is given.

Letter opinion issued by the Office of the Attorney General of Texas in Austin, Texas, providing an interpretation of Texas law. It provides the opinion of the Texas Attorney General, Dan Morales, regarding a legal question submitted for clarification: Whether article I, section 16 of the Texas Constitution precludes the Texas Workers' Compensation Insurance Facility from denying workers' compensation insurance coverage to an employer that, prior to the effective date of section VII.f.6 of the facility's rules, committed the conduct that section VII.f.6 describes.
