Compounds of Cd-Si-As required for sputtering targets and evaporation charges were synthesized by direct fusion. These include CdSiAs/sub 2/, Cd/sub 3/As/sub 2/, CdAs/sub 2/ and SiAs. Polycrystalline ingots of CdSiAs/sub 2/ were found to be porous, with the chalcopyrite structure, and with minor amounts of other phases such as CdAs/sub 2/, SiAs,As and Cd/sub 3/As/sub 2/. Sputtered films were formed in a single target RF system. A homogeneous CdSiAs/sub 2/ target was initially used, followed by composite targets consisting of CdAs/sub 2/ + Si. Films from the latter targets were superior to the others and were more extensively studied. As deposited films were amorphous, off stoichiometry, with resistivities over 10/sup 8/..cap omega..-cm and band gaps of approx. 1.4 eV. Subsequent reactive heat treatments in the 515/sup 0/ to 615/sup 0/C range resulted in crystalline films, resistivities of 1 to 10 ..cap omega.. cm, CdSiAs/sub 2/ compositions within 1% of stoichiometry, energy gap of approx. 1.55 eV, absorption coefficient of 2 x 10/sup 4/cm/sup -1/ at 0.6 ..mu..m, but with poor mechanical properties (mainly cracking). A Ta/Si0/sub 2/ substrate proved to be the best for these films. Thermal evaporation studies of CdSiAs/sub 2/ established that effusion is preferential toward Cd between …

Screening criteria and specifications are recommended to aid in the evaluation of sites proposed for nuclear waste disposal in basalt and domed salt. The recommended new criteria proposed in this report are intended to supplement existing repository-related criteria for nuclear waste disposal. The existing criteria are contained in 10 CFR 60 sections which define siting criteria of the Nuclear Regulatory Commission (NRC), and ONWI 33(2) which defines siting criteria of the Office of Nuclear Waste Isolation (ONWI) for the Department of Energy. The specifications are conditions or parameter values that the authors recommend be applied in site acceptance evaluations. The siting concerns covered in this report include repository depth, host rock extent, seismic setting, structural and tectonic conditions, groundwater and rock geochemistry, volcanism, surface and subsurface hydrology, and socioeconomic issues, such as natural resources, land use, and population distribution.

Brief descriptions of research papers in radiobiology, biochemistry, metabolism, and biophysics published during 1979 are presented. The research was conducted by investigators in the Dept. of Radiation Biology and Biophysics. (ACR)

The compilation has 1702 thermal spring locations in 23 of the 50 States, arranged alphabetically by State (Postal Service abbreviation) and degrees of latitude and longitude within the State. It shows spring name, surface temperature in degrees Fahrenheit and degrees Celsius; USGS Professional Paper 492 number, USGS Circular 790 number, NOAA number, north to south on each degree of latitude and longitude of the listed. USGS 1:250,000-scale (AMS) map; and the USGS topographic map coverage, 1:63360- or 1:62500-scale (15-minute) or 1:24000-scale (7.5-minute) quadrangle also included is an alphabetized list showing only the spring name and the State in which it is located. Unnamed springs are omitted. The list includes natural surface hydrothermal features: springs, pools, mud pots, mud volcanoes, geysers, fumaroles, and steam vents at temperature of 20{sup 0}C (68[sup 0}F) or greater. It does not include wells or mines, except at sites where they supplement or replace natural vents presently or recently active, or, in some places, where orifices are not distinguishable as natural or artificial. The listed springs are located on the USGS 1:250,000 (AMS) topographic maps. (MHR)

The Illinois State Geological Survey is conducting geological and geochemical investigations to evaluate the potential of New Albany Group shales as a source of hydrocarbons, particularly natural gas. Geological studies include stratigraphy and structure, mineralogic and petrographic characterization; analyses of physical properties; and development of a computer-based resources evaluation system. Geochemical studies include organic carbon content and trace elements; hydrocarbon content and composition; and adsorption/desorption studies of gas through shales. Separate abstracts have been prepared for each task reported.

This proceedings covers instruments and process control involved in the conversion of fossil fuels into synthetic fuels, spurred in part by response to the energy crisis of the 1970s and attending inflation.

This first edition of the Atlas provides, in reference form, a central source of information to consumers on key contacts concerned with energy in the US. Energy consumers need information appropriate to local climates and characteristics - best provided by state and local governments. The Department of Energy recognizes the authority of state and local governments to manage energy programs on their own. Therefore, emphasis has been given to government organizations on both the national and state level that influence, formulate, or administer policies affecting energy production, distribution, and use, or that provide information of interest to consumers and non-specialists. In addition, hundreds of non-government energy-related membership organizations, industry trade associations, and energy publications are included.

This is the final volume of a history of the research work of Seaborg and associates in the University of Chicago Metallurgical Laboratory, Chemistry Section C-1. The work was concerned with the development of chemical procedures for the extraction of plutonium, for the purification of plutonium and, in the later phases, for research on the isotopes of other heavy elements including other transuranium elements. The style of the history is that of a diary with footnotes giving additional information.
