Self-healing Composite of Thermoset Polymer and Programmed Super Contraction Fibers
Issue Date: Aug. 30, 2016
Guoqiang Li and Harper Meng
This patent protects a novel polymer that uses the two-step “close then heal” process for macrocracks. This polymer contains fibers that are programmed into a temporary shape which is then embedded into a conventional polymer matrix. When a macroscopic crack is created in the polymer matrix, the crack is healed by heating the material. The fibers shrink and close the crack. Further heating melts the fibers and the molten thermoplastic molecules are sucked in the narrowed crack by capillary force and diffused into the fractured SMP. When cooled down, the material hardens, thus healing the crack at the molecular level. The invention can be used in any lightweight structure such as aircraft, ships, cars, trains, piping, pressure vessels and non-load bearing electronic devices such as computers and cell phones.
Energy Efficient Job Scheduling in Heterogeneous Chip Multiprocessors Based on Dynamic Program Behavior Using PRIM Model
Issue Date: Sept. 6, 2016
Lu Peng and Bin Li
This patent protects a new computer chip configuration that is optimal at efficiently scheduling multiprocessor time through hardware interfaces. The program scheduler, which is responsible for program-to-core assignments during runtime, is aware of differences between integrated processors and program behaviors and makes optimal job assignments to a given core during runtime. In short, this invention will help improve the battery life of cell phones.
Fatigue Monitoring for Composite Materials
Issue Date: Oct. 25, 2016
Michael Khonsari and Mehdi Naderi Abadi
This patent protects a new method to monitor, analyze and predict when a material will fail under cyclic loading. Specifically, through this methodology, the failure in a material can be anticipated solely on a temperature reading of the material while being loaded. The benefit of the method is that it does not require full load history to be able to anticipate fatigue failure. The anticipated fatigue failure can be achieved with a short history of the temperature of the material in service. This technology has applications in machinery, pumps and turbines.
Inhibitors of PFKFB3 for Cancer Therapy
Issue Date: Nov. 15, 2016
Yong-Hwan Lee and Jeong Do Kim
This patent protects a new analytical tool for small molecules, inhibitors of the enzyme PFKFB3. These inhibitors were tested in cervical and breast cancer cell lines leading to massive cell death. PFKFB3 plays an important role in glycolysis – the metabolic pathway in eukaryotes which has been found to be overexpressed in multiple types of cancer including: thyroid, breast, colon, prostatic and ovarian tumor cell lines. The unique feature of this invention is that it can be applied broadly to many types of cancers.
Thermosetting Shape Memory Polymers with Ability to Perform Repeated Molecular Scale Healing
Issue Date: Nov. 15, 2016
This patent protects a novel polymer and the methods to make the polymer which can mimic the biological healing process of human skin by first closing the wound followed by a healing step. This approach, termed the “close then heal” process, uses a shape memory polymer for purposes of narrowing or closing a microscopic crack and then molten thermoplastic particles are used for healing at the molecular scale. The unique feature of the invention is that it enables a material to close macroscopic defects multiple times even if another wound occurs in a previously healed area. The invention can be used for protecting civilian structures, law enforcement and military equipment and to help seal cracks in any structure such as aircraft, ships, cars, trains, asphalt and concrete.
Apparatus and Method for Nanocomposite Sensors
Issue Date: Dec. 13, 2016
