    Abstract: Provided are electron emitters based upon diamondoid monolayers, preferably self-assembled higher diamondoid monolayers. High intensity electron emission has been demonstrated employing such diamondoid monolayers, particularly when the monolayers are comprised of higher diamondoids. The application of such diamondoid monolayers can alter the band structure of substrates, as well as emit monochromatic electrons, and the high intensity electron emissions can also greatly improve the efficiency of field-effect electron emitters as applied to industrial and commercial applications.

    Abstract: Diamond clusters are used as a polishing material of free abrading particles, each being a combination of artificial diamond particles having primary particle diameters of 20 nm or less and impurities that are attached around these diamond particles. The density of non-diamond carbon contained in the impurities is in the range of 95% or more and 99% or less, and the density of chlorine contained in other than non-diamond carbon in the impurities is 0.5% or more and preferably 3.5% or less. The diameters of these diamond clusters are in the range of 30 nm or more and 500 nm or less, and their average diameter is in the range of 30 nm or more and 200 nm or less. Such polishing material is produced first by an explosion shock method to obtain diamond clusters and then removing the impurities such that density of non-diamond carbon contained in the impurities and density of chlorine contained in other than non-diamond carbon in the impurities become adjusted.

    Abstract: The present invention relates to a method for producing colorless, single-crystal diamonds at a rapid growth rate. The method for diamond production includes controlling temperature of a growth surface of the diamond such that all temperature gradients across the growth surface of the diamond are less than about 20° C., and growing single-crystal diamond by microwave plasma chemical vapor deposition on the growth surface of a diamond at a growth temperature in a deposition chamber having an atmosphere, wherein the atmosphere comprises from about 8% to about 20% CH4 per unit of H2 and from about 5 to about 25% O2 per unit of CH4. The method of the invention can produce diamonds larger than 10 carats. Growth rates using the method of the invention can be greater than 50 μm/hour.

    Abstract: Methods of synthesizing polycrystalline bodies using rhombohedral graphite materials are disclosed and described. One procedure includes providing a particulate graphite source having a majority of carbon atoms oriented in a rhombohedral polytype configuration. The particulate graphite source can be shaped into a desired shape having a porosity from about 0% to about 30%. A sufficient amount of heat and pressure can be applied to the desired shape to form diamond and consolidate the diamond into a polycrystalline body.

    Abstract: Carbon components contained in large quantities in bone components are isolated. The isolated carbon components are gasified and plasma-processed by means of microwave or high-frequency heating and the etching curing of hydrogen atoms is utilized to form diamond-like film on the surface of the base material to produce an esthetically pleasing ornament.
