Abstract: Liquid compositions of ammonia borane and a suitably chosen amine borane material were prepared and subjected to conditions suitable for their thermal decomposition in a closed system that resulted in hydrogen and a liquid reaction product.

Abstract: Method of producing ammonia borane, comprising providing polyborazylene; digesting the polyborazylene with a dithiol-containing agent to produce a boro-sulfide compound and a byproduct; converting the byproduct to the boro-sulfide product of step (b) by reaction with a first alkyl-tin hydride; and, converting the boro-sulfide compound produced in steps (b) and (c) to ammonia borane by reaction with a second alkyl-tin hydride.

Abstract: A method for designing an HVAC system. The method may comprising operating a computer program to create a virtual floor plan, detecting automatically, by the computer program, an enclosed space within the virtual floor plan, and calculating automatically, by the computer program after the detecting, a load corresponding to the enclosed space. The method may further include providing, by the computer program, a palette of HVAC components, instructing the computer program to assign at least one HVAC component from the palette to the enclosed space, and assigning automatically, by the computer program, a capacity to the at least one HVAC component, the capacity corresponding to the load calculated for the enclosed space.

Abstract: A system and method for designing an HVAC system using a database to manage values of properties corresponding to design elements. Elements include substantially all physical components and connections available for creating an HVAC system design. A user interface represents design elements arbitrarily selectable by a user and connectable to one another in a schematic to establish the HVAC system design. The system may provide, automatically, default values corresponding to the properties corresponding to the design elements. A user may select arbitrarily, from the design elements, an arbitrary number of selected design elements to be interconnected in the HVAC system design. A user may place and interconnect each arbitrary design element, while the system calculates, automatically, values of properties characterizing the arbitrary design elements; validating correctness of the interconnections and properties, calculating performance parameters, and providing drawings.
