Patent number: 11298689Abstract: Disclosed are various combinations of three different metal-oxide photocatalysts with three different bandgaps that can be used to harvest multiple wavelengths of incident solar radiation and to thus efficiently degrade recalcitrant contaminants. The photocatalysts are from the class of transition metal oxides and are non-toxic compounds based on earth-abundant materials. In some embodiments, particles of the photocatalysts are formed to be greater in diameter than about 0.1 ?m in order to make them easier to filter out after treating the contaminant. In some embodiments, the metal-oxide photocatalysts are zinc oxide which is ultraviolet active, hematite which is active in the visible spectrum, and copper oxide which is active in the near infrared spectrum. Various combinations in various embodiments achieve measured contaminant degradation rates greater than the sum of the degradation rates of the individual photocatalysts that make up the combination.Type: GrantFiled: August 20, 2018Date of Patent: April 12, 2022Assignee: UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: Emily Asenath-Smith, Emma K Ambrogi

Patent number: 11293724Abstract: Enclosed structures, such as guard towers, are provided which are designed to be easily transportable, constructed easily onsite and erected in a manner which produces an exceptionally blast resistant structure that is also advantageously designed for positioning within a perimeter wall. In particular, in some embodiments, the guard towers have a pentagon shape and are comprised of a plurality of composite panels. Each panel is able to be constructed onsite. The panels typically have a rectangular shape with at least one half of the panel constructed as a solid composite of concrete and metal. Once the panels are constructed, the panels are erected and arranged in a pentagon shape. The panels are bolted together with the use of vertical face connections. These connections provide better structural integrity, retained over time, particularly after subjection to a blast. In addition, the pentagon shape provides improved safety when positioned along a perimeter wall.Type: GrantFiled: January 14, 2020Date of Patent: April 5, 2022Assignee: UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: John M Hoemann, Justin M Roberts

Patent number: 11290181Abstract: Measurement of entangled photon quantum wavefunction properties is vital for studying the fundamentals of entanglement and for future applications in quantum communications, quantum metrology, quantum sensing and imaging. Despite its importance, measuring the wavefunction is difficult, particularly in pulsed and other systems with system features and wavefunctions changing in space and time. This invention uses ghost imaging techniques to directly measure the entangled photon wavefunction of pulsed origin temporal and polarization entangled photons. The invention may be used to improve wavefunction quality after propagation through turbulent or scattering media.Type: GrantFiled: March 18, 2021Date of Patent: March 29, 2022Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Ronald E.

Patent number: 11287229Abstract: The present invention is directed to a process for making combustible foam celluloid munition parts having high aspect ratios, different densities or having an insert embedded into the foam celluloid munition part. The process for making such foam celluloid munition part requires pre-soaking dry particles of celluloid, placing the celluloid particles into a munition part mold, exposing the celluloid particles to high heat and pressure until the celluloid particles expand and fuse into the shape of the mold. Varying the density or the size of the celluloid particles used in the process produces munition parts having different densities. In addition, the placement of inserts into the particles prior to exposure to high heat and pressure produces munition parts having inserts that are useful for identification and tracking of such parts.Type: GrantFiled: January 29, 2020Date of Patent: March 29, 2022Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Viral Panchal, Chong Peng, Dale Conti, Ming-Wan Young, Tianyi Huang

Patent number: 11280588Abstract: Ready armor modular protective systems that can be rapidly deployed in an urban environment. Exemplary armor systems include a container, and a wall assembly that fits inside of the container when in a collapsed configuration. The wall assembly includes a first end section, a second end section, a constraint mechanism, and first and second locking mechanisms.
