Patent number: 10813585Abstract: An exemplary breath analysis system may include a sampling chamber having a molecule collector disposed therein. The molecule detector may be configured such that volatile organic compounds (VOCs) present in a breath sample introduced to the sampling chamber adhere to the molecule collector. A heating element may introduce heat within the sampling chamber, causing release of at least a portion of the VOCs adhered to the molecule collector. An analysis device (e.g., a mass spectrometer or tetrahertz (THz) spectrometer) may identify one or more target VOCs from among at least the portion of the VOCs released from the molecule collector and generate an output representative of the identified one or more target VOCs. The output may include information that quantitates a concentration of the one or more target VOCs with respect to a source of the breath sample.Type: GrantFiled: December 16, 2019Date of Patent: October 27, 2020Assignee: The University of North TexasInventors: Guido Fridolin Verbeck, IV, John Redmond, Tim Wing

Patent number: 8748608Abstract: Dopamine D3 receptor antagonists and partial agonists are known to modulate the reinforcing and drug-seeking effects induced by cocaine and other abused substances. By introducing functionality into the butylamide linking chain of the 4-phenylpiperazine class of ligands, improved D3 receptor affinity and selectivity, as well as water solubility, is achieved. A series of linking-chain derivatives are disclosed wherein functionality such as OH or OAc groups have been introduced into the linking chain. In general, these modifications are well tolerated at D3 receptors and achieve high selectivity over D2 and D4 receptors.Type: GrantFiled: June 15, 2007Date of Patent: June 10, 2014Assignees: The United States of America as Represented by the Secretary of the Department of Health and Human Services, The University of North Texas Health Science Center at Fort WorthInventors: Amy Hauck Newman, Peter Grundt, George C. Cyriac, Robert Luedtke, Jianjing Cao

Publication number: 20130130014Abstract: A method and chemical composition and material structure for improving fretting wear in substrates, particularly carbon-carbon composite (CCC). The invention relates to trilayer coatings, comprising a base of hard ZrO2, a middle layer of Al2O3, and atop layer of lubricious ZnO. The coatings of the present invention exhibit conformality and pore-filling down to approximately 100 microns into a carbon-carbon composite to which they are applied. The methods for preparing the coatings include a chemical vapor infiltration route, such as an atomic layer deposition (ALD) process, to uniformly and conformally coat the porous and open structure of CCC with a solid lubricant trilayer of ZnO/Al2O3/ZrO2 that results in significant improvement (65%) in fretting wear.Type: ApplicationFiled: May 18, 2012Publication date: May 23, 2013Applicant: The University of North TexasInventors: Thomas W. Scharf, Hamidreza Mohseni, Jaimie S. Tiley

Publication number: 20130112496Abstract: An acoustic material can be electromagnetically tuned to produce alterations in its acoustical properties without physical contact. The acoustic material should contain a periodic structure and a medium that has acousto-elastical properties that can be altered through the application of electromagnetic radiation. Changes in volumetric properties such as density result in changes to the velocity at which sound passes through the material. The acoustic material can be a phononic crystal that undergoes a change in its acoustic bandgap after being subjected to electromagnetic radiation. This electromagnetic tuning ability results in the ability to change the acoustic properties of various phononic devices without physical contact.Type: ApplicationFiled: May 2, 2012Publication date: May 9, 2013Applicant: The University of North TexasInventors: Arup Neogi, Ezekiel Walker

Publication number: 20120143495Abstract: Methods and systems for indoor navigation utilize a smartphone equipped with various sensors. When a person whose initial position is unknown, and in some circumstances whose sight has been impaired, specifies a destination, the navigation system will calculate the coordinates of his/her present location from the sensor readings. It will then calculate the distance to be traveled to the destination and form routes to direct him/her towards the desired location. These steps are carried out using sensor readings and in some cases magnetic maps of the interiors of buildings stored on the smartphone. In some cases dynamic time warping (“DTW”) is used to align a recorded signature of the person's movement through the building with a stored magnetic map in order to identify the person's location within the building.Type: ApplicationFiled: October 13, 2011Publication date: June 7, 2012Applicant: The University of North TexasInventor: Ramanamurthy Dantu

Publication number: 20120118153Abstract: Fluorinated metal-organic frameworks (“FMOFs”) are capable of adsorbing and desorbing hydrocarbons, namely, C6-C8 hydrocarbon oil components (n-hexane, cyclohexane, benzene and toluene). FMOFs can be arranged in a variety of configurations and have internal hollow channels and cavities. In FMOFs, hydrogen atoms have been substituted completely or partially with fluorine atoms or fluorinated groups in each linking organic ligand. These FMOFs can adsorb C6-C8 hydrocarbons, up to 500 kg/m3 as demonstrated for toluene, through a combination of superhydrophobicity and capillary action. No water adsorption was detectable even under extreme conditions including moist air near 100% relative humidity and immersion in water for multiple weeks, demonstrating far superior water resistance to BPL carbon and zeolites. These materials are stable and can be readily recycled by simple desorption many times.Type: ApplicationFiled: October 7, 2011Publication date: May 17, 2012Applicant: The University of North TexasInventors: Mohammad A. Omary, Chi Yang
