Abstract: A high-throughput method for identifying single crystal hexagonal-SiC off-axis surfaces that support surface chemistries and kinetics to selectively produce various epitaxial growth modes of the metastable 3C-SiC polytype is provided. In execution of the aforementioned method, the present invention also encompasses the use of a single crystal hexagonal-SiC domed substrate, and a method for manufacturing thereof. Said method for screening silicon carbide growth surfaces is comprised of: fabrication of a silicon carbide domed substrate; forming a step-terrace growth surface on the domed surface of said silicon carbide domed substrate by hydrogen etching; performing silicon carbide deposition upon said growth surface, thereby creating an silicon carbide epitaxial domed wafer; and characterization of said silicon carbide epitaxial domed wafer. Silicon carbide deposition upon a silicon carbide domed growth surface allows for the modulation of the supersaturation ratio under a single set of growth conditions.

Abstract: An aerosolized HVAC/R system solvent for decontaminating HVAC/R components and line sets The solvent contains 25-90 wt % propellant, and 10-75 wt % solvent mixture which is about 60-95 wt % trans-1,2,dichloroethylene, about 5-20 wt % n-propanol, and an inerting constituent providing a weight percent ratio of the inerting constituent to n-propanol of less than 1.5. The solvent is packaged in a container that is connected to the HVAC/R components or line sets to be decontaminated for supplying the solvent mixture under pressure to the HVAC/R components or line sets.

Abstract: A mounting pad system for securing equipment, such as an HVAC outdoor unit or a standby generator, is provided in the form of a lightweight fillable pad member having a plurality of receivers located on a top surface of the pad member. The receivers are associated with attachment points located on the equipment and are used to secure the equipment to the pad. The pad member contains a filling port on its top surface and is configured as a molded hollow shell containing a gelling material which, when mixed with water, provides support to reduce deflection of the pad member caused by the equipment secured to the pad, prevents damage to the pad that would otherwise be caused by the expansion of internal contents upon freezing and prevents leakage of internal contents of the fillable pad in the event of an unintended breach in the hollow shell. The pad member is provided with at least one through-hole that acts as a supporting structure.

Abstract: The present invention is an apparatus for curing composites out-of-autoclave and out-of-oven. The apparatus is a multilayered composite tool for shaping and curing composites. It also contains a sealant layer and composite resistive heating element on the tool's surface. This heating element provides heat to the composites during cure while binding it to the other layers, eliminating the need for external heat from autoclave and oven sources. A ceramic layer is applied to the top surface of the resistive heater for electrical insulation, heater protection and to provide a smooth surface for finish for the composite components being processed with the invention. A method for using the invention is also described. Finally, one embodiment of the invention is presented where a negative composite tool is created to apply additional pressure to the composite component during curing. This additional pressure enables the current invention to more closely mimic autoclave composite processing.

Abstract: A process is disclosed for cooling a material that includes semiconductor nanoparticles in matrix material by anti-Stokes up-conversion. The semiconductor nanoparticle matrix is irradiated by a laser with a photonic wavelength matched to the anti-Stokes photoluminescence of the semiconductor nanoparticle bandgap. The semiconductor nanoparticles absorb the laser photon and phonons (heat) from lattice vibrations to photoluminescence photons with higher energy than the photon that were absorbed. A net cooling effect is generated from the lower energy and lower temperature in the material after anti-Stoke up-conversion.

Abstract: A window assembly heat transfer system is disclosed in which a window member has a selected transparency to monitored or sensed electromagnetic wavelengths. One or more passages are provided in the window member for flowing a single-phase or two-phase heat transfer fluid. A mechanism allows either evaporation or condensation of the fluid and/or balancing of a flow of the fluid within the passages. In one embodiment, the window assembly can be made by producing passages in a top surface of a first single plate, optionally producing passages in a bottom surface of a second single plate and bonding the top surface of the first plate to a bottom surface of a second single plate to form the window member with the passage or passages. In another embodiment, the window assembly can be made by providing a core around which the window member material is grown and thereafter removing the core to produce the passage or passages.

Abstract: An air conditioning apparatus for cooling and/or dehumidifying an interior space, such as the interior of a shelter or tent that provides for simplified manufacturing, simplified inspection and servicing, reduced noise, reduced vibration, reduced weight, increased ruggedness and health monitoring. Structural components of the apparatus are fabricated from foam-filled molded parts with interlocking components, and the unit is assembled and tested without any outside cover, but once the cover is installed, additional structural strength is obtained from the cover. A refrigerant flow sensor along with other sensors are used to determine actual real time cooling capacity measurements and health monitoring.
