Goodnite, Huck, did you happen to read the part about the MIR that I added on edit, take two chip ahoys paste on the morsels. Personal attacks on my hohoincoherant fashion are getting a tad pit too personal, you are not funny, I am. Too bad. Chuckachipsfallwheretheymay P.S.- I thought of you and NUKE together: Chuca on Silicon Investor PS- Permission herebt granted to send to whoever. " Ernest Moniz, the Under Secretary of Energy, said Tuesday in an interview that experiments at a South Carolina storage site in the early 1980's showed the process of concentrating the waste was producing high levels of explosive benzene gas. But rather than trying to develop a new procedure, "some rather poor judgment was used," Dr. Moniz said, and instead, engineers tried to make the process safe. ... The liquids would then be reduced in volume in an evaporator, and the resulting solids, which were not highly radioactive, would be mixed with cement. The solids would go to the glass factory.
But they discovered that copper and palladium already in the tanks were aiding in another reaction, one that produces benzene.
The chemical problems at Hanford are different, but experts there are worried by the problems at Savannah River.
Jerry Pollet, executive director of Heart of America Northwest, an environmental group, said that "from a management point of view, it raises a huge concern here."
The Energy Department signed a contract under which it promises to provide the wastes to a glass factory to be built by BNFL, and if it fails to deliver, Pollet said, it could pay large penalties.

In addition, Rhombic is pursuing agreements with other companies to develop applications based on material modification by the addition of impurities. The market for boron-doped diamond film for the first year is projected to be in excess of $30 million, with markets exploited by Drunker, DeBeers of Europe, and Norton Diamond of the United States.
Nanophase diamond powders are a new material that was developed for the Russian military program. It is a diamond powder made up of very small pieces of diamond with a narrow distribution of sizes about four nanometers in diameter. Rhombic is developing a process to press and bind the nanophase diamond powder to form a hard material. The forced diffusion process can change the mechanical properties of diamond grit by boron doping, making the grit 10 to 15 percent harder than ordinary diamond grit. The market for diamond grit is approximately $70 million a year.
With the release of the Patent "Field Enhanced Diffusion Using Optical Activation", Rhombic Corporation is preparing to establish its first manufacturing/laboratory site at Columbia, Missouri, to produce Positive (P) type diamond film, and to finalize the development of Negative (N) type diamond.
By diffusing certain elements into the diamond interstices, Rhombic has already created a number of integrated N-type diamond circuits, and has immediate plans to produce diamond diodes and switches. Diamond is unique among all materials since it is both heat and radiation resistant, and is so electrically conductive that diamond chip speed is potentially a thousand times faster than silicon. Harder cutting tools and abrasives, diamond tv screens and computer monitors, sensors, bearings and radar are among a number of potential applications of doped diamond which Rhombic Corporation will be developing.

The manufacturing of fine dispersed materials of the size form nanometers with a homogeneous interior and an additional coating is according to the invention realized by a plasma processing of high efficiency. These disperse composite materials (DCM) have specific properties of abrasion or wear resistance, friction, catalytic action or sintering e.g. for high temperature superconductors.
Description:
The invention refers to chemistry, metallurgy, material sciences and micro-technology for manufacturing disperse composite materials as powders which consist of small particles and which are covered with another material. These dispersed composite materials (DCM) can be produced as catalysts, as abrasive, wear-resistant grinding material of high strength of with surfaces without magnetic permeability. A further use of the composite materials applies the structural properties of very small size particles of very high strength as these are needed for composite resistors, or during the process of soldering or welding of ceramic materials (high temperature superconductors, rigid electrolytes etc.) with metals.
In production of disperse catalysts one of the important problems is to produce catalytic coatings thin and strongly connected with an initial disperse material (carrier). It is especially necessary when expensive metals such as platinum, gold, iridium, palladium, or rhodium are used as catalytic active components of coatings since the coating has to have a strong adhesion to the carrier to provide a high life time of the catalyst.
In practice of creating new materials there is a wide use of various disperse composite materials on the base of diamonds, oxides, silicon silicates or nitrides, titanium, tungsten, zirconium, vanadium, molybdenum, boron, aluminum etc., covered with shells of one or several metals: nickel, cobalt, silver, copper, molybdenum, tungsten, titanium, aluminum, tin, lead, zinc, zirconium, metals of the platinum group, etc. These materials are used in the processes of depositing various (for example, strengthening, abrasive, abrasive resistant, heat resisting with no magnetic permeability, and also as a conductive phase in composite resistor) coatings upon the product as well as for creating high-strength structural composite materials. Metalization of initial powders leads to the absence of contacts between the particles of the carrier material among themselves, i.e. to matrix structure of mascroscopic compositions in the product. Besides the deposition of coatings, being diffusion barriers for atoms of initial powders, allows to suppress recrystallization during the process of manufacturing the product by sintering method. It opens a possibility of making the stable materials with a super small sized grain. Besides that the DCM can be used as an intermediate material during soldering or welding various ceramic and other nonmetal items with metals, for example, as a solder for junction of high temperature superconductors (HTSC) of electrolytes with current leads. Coating material for this method can be, for example, silver, which is one of few metals not interacting with oxygen HTSC materials and used for treading low resistive contacts.
Among the requirements for DCM there is a high adhesion of coatings to the disperse carrier and controllability of the coating process necessary to take place under the given parameters of particle structure and content and leading to homogeneity of the produced powders.
All the hitherto known manufacturing methods for these materials have a number of shortcomings. These are: insufficient continuity of the obtained coating, poor adhesion of the deposited component to the particles of the initial material, formation of sinters, containing a few particles of an initial material inside the same shell that results in heterogeneity of the produced powders and, in the final analysis, in a strong degrading of the strength of the produce, its wear resistance and applicability. One of the manufacturing methods coming closest to the methods of the following invention is the plasma deposition (H.S.Shin, D.G. Goodwin, Deposition of diamond coatings on articles in a microwave plasma enhanced fluidized reactor, Materials Letters Vol 19, p. 119-122 (1004); R. Quellette, M. Barbier, P.Cheremisionoff, Low Temperature plasma technology applications, Ann Arbor Science publications, Ann Arbor, 1980).
The difficulties of the hitherto known methods are overcome according to the invention described in the following equipment and method where – according to the invention – the deposition process is essentially better controlled and the exactness of the deposition process of the coating components onto the fine dispersed basic material is performed. Accordingly the sintering of the carrier material is avoided during the process of deposition of the covers and simultaneously the adhesion of the cover on the carrier is improved.
The equipment and the method for producing the DCMs consists in filling of a working chamber with a plasma producing gas which is being excited to plasma, and in injection of the dispersed (dusty) base material as well as the one or other components of the coating material being in the gas or vapor phase.
A special application of this method and apparatus is the manufacturing of coatings which leads to a very low cost conversion of long lived radio nuclides (mostly from nuclear reactors) into stable nuclides or the elimination of plutonium by transmutation into uranium. It is well known that nuclear reactions in host metals (nickel, palladium, titanium, zirconium, thorium etc.) for high concentrations of hydrogen ions of its isotopes are used which are occuring as low energy long time processes in nuclear distances in the range of picometers (H.Hora et al. Transactions fo the American Nuclear Society, 766, 144 (1997)). It is essential that very high surfaces with multilayers of appropriate host metals are made as it is done according to the invention with the DCMs. The material added to the plasma for production the coatings (on glass or similar carrier materials of the size around 10 um) is then one or in a sequence further mentioned host metals as well as charges of the long time radio nuclides for transmutation, preferably into the surfaces or in interfaces. |
