Patent number: 11542042Abstract: A matrix thruster that may be used to reposition and/or stabilize a CubeSAT satellite. The matrix thruster includes a conductive plate with an opening, a plurality of wires within the opening, a power supply electrically connected to the conductive plate or each of the plurality of wires via an inductor, and an electrical switch. The electrical switch creates a current change that creates an electric potential spike across the inductor. The electric potential spike across the inductor initiates an arc discharge between one of the wires and the conductive plate, which forms plasma that ejects cathode particles from the matrix thruster. Using multiple wires (e.g., four titanium wires) extends the lifetime of the thruster, as each wire restores an inter-electrode film needed for the other wires to continue generating plasma.Type: GrantFiled: September 15, 2020Date of Patent: January 3, 2023Assignee: The George Washington UniversityInventors: Keir Daniels, Zachary Switzer, Dimitris Kiaoulias, Michael Keidar

Patent number: 11542495Abstract: A sample containing particles having high-molecular-weight (HMW) DNA is entrapped in a gel matrix, and the gel matrix is exposed to a lysis reagent configured to release the HMW DNA from the particles. The HMW DNA may be purified by subjecting the gel matrix to an electrophoretic field that removes the HMW DNA from the particles, lysis reagents, and/or other sample constituents, from the gel matrix such that the HMW DNA remains. The gel matrix may be subjected with DNA cleavase reagents configured to cleave at specific DNA sequences within the HMW DNA to liberate defined segments of the DNA as fragments of reduced size. The gel matrix may also be subjected to an electrophoretic field, which moves and separates the DNA fragments from uncleaved DNA of the HMW DNA, which remains substantially immobile. The electrophoretically separated DNA fragments may be isolated from the gel matrix.Type: GrantFiled: November 21, 2016Date of Patent: January 3, 2023Assignees: Sage Science, Inc., Washington UniversityInventors: Robi David Mitra, Jeffrey Milbrandt, Ezra Solomon Abrams, Todd J.

Patent number: 11530245Abstract: Mussels strongly adhere to a variety of surfaces by secreting byssal threads that contain mussel foot proteins (Mfps). Recombinant production of Mfps presents an attractive route for preparing advanced adhesive materials. Using synthetic biology strategies, Mfp5 together with Mfp5 oligomers containing two or three consecutive, covalently-linked Mfp5 sequences (named Mfp52 and Mfp53) were synthesized. Positive correlations were found between Mfp5 molecular weight and underwater adhesive properties, including adhesion force, adhesion work, protein layer thickness, and recovery distance. Dopa-modified Mfp53 displayed a high adhesion force (201±36 nN ?m?1) and a high adhesion work (68±21 fJ ?m?1) for 200 s cure times, higher than previously reported Mfp-mimetic adhesives. Results disclosed herein highlight the power of synthetic biology in producing biocompatible and highly adhesive Mfp-based materials.Type: GrantFiled: August 28, 2019Date of Patent: December 20, 2022Assignee: Washington UniversityInventors: Fuzhong Zhang, Eugene Kim
