Patent number: 7572872Abstract: Nanostructured chemicals such as polyhedral oligomeric silsesquioxanes, polyhedral oligomeric silicates, and polyhedral oligomeric metallasesquioxanes are attached to living and nonliving systems as biomaterials to provide a nanoscopic topology that favors biomimetic function and cellular modulation. The resulting surface is nanoscopically thin, nanoscopically dispersed, provides systematic chemistry, surface area, surface volume, surface topology, and is essentially free of impurities, and has controllable properties through selection of composition, R groups, nanostructure size and topology. Highly shape specific and chemically tailorable nanostructured molecules are sized to biological material dimensions and are compatible with all sterilization methods.Type: GrantFiled: April 24, 2006Date of Patent: August 11, 2009Inventors: Jason T. Flodin, Joseph D. Lichtenhan, Joseph J. Schwab, Yi-Zhong An, Xuan Fu, Zachary Kemp

Patent number: 7501479Abstract: A method for the cationic polymerization of unsaturated biological oils (e.g., vegetable oils and animal oils) based on the cationic reaction of double bonds initiated by superacids is provided. The process occurs under very mild reaction conditions (about 70-110° C. and atmospheric pressure) and with short reaction times. The polymerized oils have a viscosity about 10 to 200 times higher than the initial oil and relatively high unsaturation (only about 10-30% lower than that of initial oils).Type: GrantFiled: May 7, 2007Date of Patent: March 10, 2009Assignee: Pittsburg State UniversityInventors: Mihail Ionescu, Zoran S.
