Publication number: 20230292686Abstract: Disclosed herein are markers which are associated with chilling tolerance and provide for breeding methods to identify such plants to integrate this trait into cereal plants and further to identify analogous markers in other cereal plants. Importantly, these markers are not linked with deleterious traits such as tall plant height or tannin content, providing for the creation of plant varieties and elite plant varieties with chilling tolerance, dwarf plant height and lack of tannins.Type: ApplicationFiled: March 22, 2021Publication date: September 21, 2023Inventors: Geoffrey P.

Patent number: 9943467Abstract: Provided are dental articles, and methods of making articles, having an aesthetic inorganic coating based on zirconia at least partially stabilized with yttrium oxide, calcium oxide, cerium oxide, or magnesium oxide. Stabilized zirconia coatings were found to provide a smooth, low friction surface having high abrasion resistance. These coatings are particularly applicable to orthodontic appliances. While virgin stabilized zirconia coatings can often have an undesirable color cast, it was discovered that this color cast can be substantially eliminated by heat treating the coated appliance in an oxygenated environment. The combination of depositing a stabilized zirconia coating and subsequently heat treating to decolorize the coating provides a surprisingly robust, stable, low-friction coating that is also aesthetic.Type: GrantFiled: December 22, 2016Date of Patent: April 17, 2018Assignee: 3M Innovative Properties CompanyInventors: Geoffrey P. Morris, William E. Wyllie, II, Steven D. Theiss

Publication number: 20110171591Abstract: The invention provides an orthodontic composition, related methods and packaged articles that include a hardenable component, a hardener, and a heat-modified inorganic mineral filler. The composition displays improved hardened remnant cleanup compared with compositions using traditional hard mineral fillers, while maintaining acceptable handling, bond strength and mechanical properties. Bond strength enhancement is achieved by heat-modifying a soft mineral filler, a process by which water of hydration is eliminated from the microstructure of the mineral to form a non-hydrated phase. By using heat-modified mineral fillers that are soft relative to human enamel, the hardened orthodontic composition can be conveniently removed using a lowspeed abrasive disk or other mild abrasion process that is safer and more comfortable for the patient. The composition is especially beneficial for use in bonding orthodontic appliances to teeth.Type: ApplicationFiled: September 8, 2009Publication date: July 14, 2011Inventors: David T. Amos, Geoffrey P. Morris
