摘要： A super-hard material is a late transition metal doped B4C ceramic. The lightweight ceramics can display Vickers Hardness in excess of 45 GPa. Transition metals, such as Ni, Co, Rh, and Pd can be doped into the boron carbide at levels up to about 2.5%. A spark plasma sintering (SPS) of an evacuated powder of B4C and the transition metal at temperatures up to 2000° C., and pressures of up to about 100 GPa forms a super-hard material as a body. The late transition metal doped B4C ceramic can be used for armor, grinding materials, thermoelectric materials, and catalysts.

摘要： Embodiments of the invention are directed to a method for production of a nuclear fuel pellet by spark plasma sintering (SPS), wherein a fuel pellet with more than 80% TD or more than 90% TD is formed. The SPS can be performed with the imposition of a controlled uniaxial pressure applied at the maximum temperature of the processing to achieve a very high density, in excess of 95% TD, at temperatures of 850 to 1600° C. The formation of a fuel pellet can be carried out in one hour or less. In an embodiment of the invention, a nuclear fuel pellet comprises UO2 and a highly thermally conductive material, such as SiC or diamond.

摘要： The present disclosure relates to compact waveguides. One example includes a primary bar, and an impedance-matched series of secondary bars that is impedance-matched with the primary bar at a connection point that joins at least one secondary bar of the impedance-matched series of secondary bars to the primary bar. The secondary bars are noncollinear and nonconcentric with the primary bar.
