Patent number: 11524279Abstract: A MXene support for a noble metal that forms a catalyst having active sites comprising single metal-layer nanostructures. The catalyst is stable under conditions for methane conversion to higher hydrocarbons and provides reduced coke formation. The results show a supported metal catalyst using the MXene where Pt atoms form one or more layers of atoms on the surface of the Mo2TiC2Tx support after it is reduced at 750° C. The catalyst shows high selectivity for C2-hydrocarbons with reduced coke formation, which can cost effectively convert methane into other valuable products.Type: GrantFiled: November 18, 2020Date of Patent: December 13, 2022Assignees: Iowa State University Research Foundation, Inc., Purdue Research FoundationInventors: Zhe Li, Yue Wu, Arvind Varma, Yang Xiao

Publication number: 20220386531Abstract: A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.Type: ApplicationFiled: June 4, 2021Publication date: December 8, 2022Applicants: Deere & Company, Iowa State University Research FoundationInventors: Brandon C.

Patent number: 11515066Abstract: Improved manufacturing processes and resulting anisotropic permanent magnets, such as for example alnico permanent magnets, having highly controlled and aligned microstructure in the solid state are provided. A certain process embodiment involves applying a particular orientation and strength of magnetic field to loose, binder-coated magnet alloy powder particles in a compact-forming device as they are being formed into a compact in order to preferentially align the magnet alloy powder particles in the compact. The preferential alignment of the magnet alloy powder particle is locked in place in the compact by the binder after compact forming is complete. After removal from the device, the compact can be subjected to a subsequent sintering or other heat treating operation.Type: GrantFiled: November 7, 2018Date of Patent: November 29, 2022Assignee: Iowa State University Research Foundation, Inc.Inventors: Aaron G.

Patent number: 11506553Abstract: We present a microelectromechanical system (MEMS) graphene-based pressure sensor realized by transferring a large area, few-layered graphene on a suspended silicon nitride thin membrane perforated by a periodic array of micro-through-holes. Each through-hole is covered by a circular drum-like graphene layer, namely a graphene “microdrum”. The uniqueness of the sensor design is the fact that introducing the through-hole arrays into the supporting nitride membrane allows generating an increased strain in the graphene membrane over the through-hole array by local deformations of the holes under an applied differential pressure. Further reasons contributing to the increased strain in the devised sensitive membrane include larger deflection of the membrane than that of its imperforated counterpart membrane, and direct bulging of the graphene microdrum under an applied pressure. Electromechanical measurements show a gauge factor of 4.4 for the graphene membrane and a sensitivity of 2.Type: GrantFiled: September 21, 2020Date of Patent: November 22, 2022Assignee: Iowa State University Research Foundation, Inc.Inventors: Liang Dong, Qiugu Wang, Wei Hong

Patent number: 11439126Abstract: Modern broilers are selected for fast growth and a large proportion of breast tissue, contributing to a top-heavy phenotype, leg disorders, and inactivity as birds reach market weight. Therefore, the objective was to motivate broilers to move through environmental enrichment. Twelve hundred Ross 308 broilers were housed in pens of 30 for 6 wk; 600 birds were exposed to a novel laser enrichment device (LASER) and 600 were control. Each device projected 2 randomly moving red laser dots onto the floor 4 times/day for 4-min “laser periods”. Seven LASER and 7 control pens, with 5 focal birds/pen (n=70), were randomly selected to be video-recorded d0-8 and once weekly for the remainder of the trial. Videos were analyzed to measure broiler time-budget and behaviors such latency to feed and distance walked during laser periods. Focal birds were gait scored weekly on-farm. A test of the Human-Approach Paradigm was carried out on wk 1 and 6 on all pens.Type: GrantFiled: October 10, 2019Date of Patent: September 13, 2022Assignee: Iowa State University Research Foundation, Inc.Inventors: Elizabeth Ann Kraayenbrink, Anna Butters-Johnson, Derek Kraayenbrink
