Invented titanium and zirconium surface modifications for medical implants, including calcium ion donor systems for in vivo formation of HA biointerfaces.Developed a monolithic toxin/CW monitoring medium.(Contract with USMC.) Three US Patent applications for Therapeutic Nitrogen Oxide Generation(Internal R&D). Developed a light metal hydride hydrogen fuel system that surpassed cryogenic storage in energy content under DoE programs. Applied for several patents for this process, as well as two more in the field of nanophase metals. Active and prolific in the R&D of many products and processes, especially in nanocomposite materials. Several patents have been issued in this field. One application prepared nanoscale semiconducting materials for use in Space Nuclear Power. (Recipient, ASME Hatsopoulis Award, Advanced Energy Systems) Another was for grain growth control in Chemical Vapor Composites (SiC). Appointed Licensee and Radiation Safety Officer. Responsible for NRC compliance and nuclear liability control for the Corporation. Many products, including cardiovascular prostheses, were successfully developed and introduced, with FDA approval. Advanced bio-compatible materials created new products in the fields of transdermal drug release systems, occlusive wound dressings, and specialty products with experimental drugs produced patents in this area. Developed a cutting and polishing lap system based on High Fractal Dimension Microstructural alloys that have low Coefficients of Friction, optimized for diamond or CUBN embedment, and sold under the Brand Names of "BATT™" and "BA5T™". Commercialy successful, within small niche market.
Designed the "XS3™" Gem Faceting Machine that featured an integral digital goniometer. Improved the design substantially, and upon announcement of the new version, the design was purchased by a commercial manufacturer.
