Abstract: A process of producing ceramic-ceramic composites, including but not limited to nuclear fuels, and composites capable of exhibiting increased thermal conductivities. The process includes milling a first ceramic material to produce a powder of spheroidized particles of the first ceramic material, and then co-milling particles of a second ceramic material with the spheroidized particles of the first ceramic material to cause the particles of the second ceramic material to form a coating on the spheroidized particles of the first material. The spheroidized particles coated with the particles of the second ceramic material are then compacted and sintered to form the ceramic-ceramic composite, in which the second ceramic material forms a continuous phase completely surrounding the spheroidized particles of the first ceramic material.

Abstract: The present invention includes purified and isolated quassinoids and synthetically derived quassinoid analogs based on a picrasane carbon skeleton. Novel sidechains at C-15 incorporating water solubilizing agents such as glycine are discussed. Therapeutic methods taking advantage of anticancer, antiviral, and herbistatic properties of these quassinoids are disclosed, including use against solid tumors and human immunodeficiency virus infected cells.
