Patent number: 12122901Abstract: One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti-jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti-jamming characteristics of the product in the hopper.Type: GrantFiled: March 28, 2023Date of Patent: October 22, 2024Assignee: Iowa State University Research Foundation, Inc.Inventors: Martin Thuo, Paul Ramon Gregory, Boyce S.

Publication number: 20240294675Abstract: This patent document provides a caged catalyst comprising a catalyst encapsulated in a cage compound of Formula I represented [ZrIV6O4(OI)4(linker)6]). The catalysts demonstrated excellent activities and size selectivity in a model RCM reaction, suggesting successful encapsulation into MOFs. ROMP of cyclopentene mediated by G3@UiO-67 achieved significantly higher molecular weight and lower dispersity than the counterpart mediated by the free catalyst. The ultra-high molecular weight polymers generated by the encapsulated catalysts demonstrated significantly improved mechanical and adhesive properties compared to the low molecular weight counterparts and commercial polymers. The simplicity and generality make this method readily applicable to the ROMP of a wide range of low-strain cyclic olefins.Type: ApplicationFiled: February 28, 2024Publication date: September 5, 2024Applicants: The Trustees of Boston College, Iowa State University Research Foundation, Inc.Inventors: Jia Niu, Wenyu Huang, Zefeng Zhou
