Fabrication Method for Hexagonal Boron Nitride Layers
Computer memory devices may employ any of various mechanisms for storing data, e.g., using memory cells each of which may be programmed to be in any of two or more states. Non-volatile memory includes memory cells each of which operates by changing the resistance across an active switching layer, e.g., an insulator, through the formation of conductive...

Doped Diamond Growth Using a Solid-State Diffusion Source
Diamond is a wide bandgap material with superior electric properties that has been studied in recent years for use in high power and high frequency electronics applications. Doping of the diamond material is necessary for effective control of defect formation, and is typically achieved by incorporating the dopant (e.g., phosphorous, boron) into the...

Bio-Grafted Plastic Granules (BCPG)
Background Removal and immobilization of metal leachates from various compounds (industrial waste, mine tailings, waste engine oil, etc.) used in construction and the built environment is critical. Specifically, the use of mine tailing in construction of roadway base and sub-base could lead to leaching of metals to surface and ground water. In response...

Synthesis of Graphene-Coated Nickel Wires and its Enhanced Mechanical Properties
Background Continuously manufacturing technology that is more compact, lighter, and sturdier than the last is a driving force in many different fields. Among the materials used for this, graphene stands out for its durability on its own and stability when combined with metals. Graphene has been integrated with conventional bulk-scale materials, e.g.,...

Safe Explicable Robot Planning
Background Effective human-robot interaction must be informed by human expectations and knowledge of the world, including how robots are expected to act/interact in various situations. However, knowledge about the robot may be inconsistent with the ground truth, which can result in the robot not meeting expectations, and the interaction integrity being...

WooplyMatt
Background According to the U.S. Environmental Protection Agency (EPA), volatile organic compounds (VOC) are compounds that have a high vapor pressure and low water solubility. Many VOCs are human-made chemicals that are used and produced in the manufacture of paints, pharmaceuticals, and refrigerants. These VOCs break down and harm the atmosphere,...

Dynamic Non-Line-of-Sight Tracking with Mobile Robots
Background The rise of autonomous machines navigating the changing outdoor environment requires not only the use of line-of-sight tracking, but also non-line of sight (NLOS) tracking. NLOS imaging techniques are divided into active and passive approaches. Active methods employ high-temporal-resolution light sources and time-resolved detectors which...
