Patent number: 11937596Abstract: An improved ultra-fast cooling system is disclosed for cryopreservation of biomaterials. The ultra-fast cooling system is designed to uniformly vitrify or partially vitrify biomaterials, including but not limited to, human biomaterials, proteins, peptides, cells, stem cells, antibodies, neurons, human tissue, organs, cornea, skin, retina, eggs, sperm, embryos, body fluids, blood, serum, lymph fluid, animal tissue, plant biomaterials, plant tissue, germ plasma, pollen, plant sap, and bioengineered tissue, without cryoprotectants or with a low concentration of cryoprotectants. Cooling rates are sufficient to uniformly cryopreserve biomaterials, and can be used in diagnostic cytology and biological cryofixation applications. Other materials also can be cooled uniformly, such as inorganic materials for processing.Type: GrantFiled: April 5, 2019Date of Patent: March 26, 2024Assignees: THE CURATORS OF THE UNIVERSITY OF MISSOURI, CRYOCRATE LLCInventors: Xu Han, Henry W.

Publication number: 20190133450Abstract: An improved optical fluorescence optical imaging system is disclosed having an excitation radiation source and an emission imaging camera. The imaging system is designed for capturing video fluorescence emission images of live animal tissue in blood containing fluorescent dye. The excitation radiation source unit can easily be adapted for use with different excitation wavelengths as can the imaging camera. Hence, the system is amenable for use with a variety of different fluorescent dyes, including those with exciting wavelengths in the ultraviolet, visible, and infrared spectral regions. The small size of both the optical excitation radiation source and emission imaging camera make the entire system relatively unobtrusive to surgeons and other health care personnel in a surgical suite.Type: ApplicationFiled: November 9, 2018Publication date: May 9, 2019Inventors: Raghuraman Kannan, Ajit Tharakan, Anandhi Upendran, Henry W.

Publication number: 20130181210Abstract: A layered heterostructure field effect transistor (HFET) comprises a substrate, a first semiconductor oxide layer grown on the substrate, and a second semiconductor oxide layer grown on the first layer semiconductor layer and having an energy band gap different from that of the first semiconductor layer, and the second layer also having a gate region and a drain region and a source region with electrical contacts to gate, drain and source regions sufficient to form a HFET. The substrate may be a material, including a single crystal material, and may contain a buffer layer material on which the first semiconductor layer is grown. The conductivity type of the first and second semiconductor layers and the composition of the semiconductor oxide layers can be selected to improve performance for desired operational features of the HFET. This layered structure can be applied for the improvement in the function and high frequency and high power performance of semiconductor HFET devices.Type: ApplicationFiled: October 29, 2008Publication date: July 18, 2013Applicant: MOXTRONICS, INC.Inventors: Yungryel Ryu, Tae-Seok Lee, Jorge Lubguban, Henry W.
