Abstract: We have demonstrated controlled growth of epitaxial h-BN on a metal substrate using atomic layer deposition. This permits the fabrication of devices such as vertical graphene transistors, where the electron tunneling barrier, and resulting characteristics such as ON-OFF rate may be altered by varying the number of epitaxial layers of h-BN. Few layer graphene is grown on the h-BN opposite the metal substrate, with leads to provide a vertical graphene transistor that is intergratable with Si CMOS technology of today, and can be prepared in a scalable, low temperature process of high repeatability and reliability.

Abstract: An apparatus and method for laser-assisted machining (LAM) of bone without raising the temperature of the surrounding bone is discussed. The method of LAM of bone involves determining a target bone needing to be machined an then scanning a high power density laser beam along the bone at a machining rate that produces low-heat affected zones (HAZ) on the target bone. The process and apparatus is advantageous over conventional technologies because it provides a chemically clean, coherent, and monochromatic beam to the region to be machined.

Abstract: A sustainable Low Water Footprint Re-circulating Aquatic System for cultivating aquatic organisms and plants. The system conserves water and energy by using gravity to move water and nutrients from the clarifier into the low water footprint management system. The novel water management system controls the volume of water in the plant grow bed such that it never rises to or above the surface, limiting evaporative water loss. Water flow to the plant grow bed is intermittent and the water management system retains water within the grow bed by capillary action, even when there is no water input. The grow bed contains microflora that convert nitrogenous wastes produced by the aquatic organisms to nitrogenous compounds useable by the plants. The clarified water is then pumped back into the animal tanks. The system is sustainable, cost effective, and highly productive, and uses 50-80% less water than conventional re-circulating aquatic production system.

Abstract: Tunable polymer-based sonic structures (“TuPSS”) are made up of sonic structures and polymers. The TuPSS has three general requirements: a) The sonic structure is composed of one or materials engineered to behave as a lens, filter, cloak, or dampener; b) Stimulus sensitive polymer is incorporated into the sonic structure; and c) The actuation of the polymer tunes the acoustic behavior of the structure in a predictable manner. The tunable polymer-based sonic structures utilize stimuli-driven physical properties of the polymers in these acoustic structures to produce a stimulus driven, or tunable, sonic structure or device. The sonic structures actively modulate mechanical vibrations that propagate through the structures, but are passive in that they do not produce mechanical vibrations. The stimuli for the structures include electric, magnetic, electromagnetic, chemical, thermal, and shaking/orientation.

Abstract: Provided is an insert adapter for direct ink writing printers (DIW) and methods of fiber alignment in direct ink writing. The insert adapter is sized to fit snugly inside a print barrel DIW 3D printer. The adapter includes channels. The DIW printer with insert adapter, can be used in a passive method for microfiber alignment in DIW printing. The method includes feeding a non-Newtonian ink including microfibers through the print barrel such that the ink flows into the channels of the insert adapter before exiting through a print nozzle, causing the microfibers to align along the direction of ink flow.
