SHEAR-ASSISTED EXTRUSION ASSEMBLIES AND METHODS (iEdison No. 0685901-21-0123)
This invention is about creating a co-extruded bi-metallic tubes where two distinct properties are required at the outer and inner part of a tube in a single step and with a minimal billet preparation. Co-extrusion of 6061 (shell) and 7075 (core), 1100 (shell) and 7075 (core), and 1100 (shell) and 2024 (core) Al alloys were completed and a sound bonding at the interface was noted. Furthermore, thickness of the sleeve and core can be controlled via the area ratio of the constituent billet material.
Solar Thermochemical Processing System and Method (iEdison No. 0685901-11-0013)
The purpose of the invention is to capture concentrated solar radiation, converting the energy to chemical energy. This is accomplished by operating a high temperature endothermic reaction such as methane steam reforming where the heat of reaction is largely or completely provided by solar energy.
DEVICES AND METHODS FOR PERFORMING SHEAR-ASSISTED EXTRUSION AND EXTRUSION PROCESSES
A process for forming extruded products using a device having a scroll face configured to apply a rotational shearing force and an axial extrusion force to the same preselected location on material wherein a combination of the rotational shearing force and the axial extrusion force upon the same location cause a portion of the material to plasticize, flow and recombine in desired configurations. This process provides for a significant number of advantages and industrial applications, including but not limited to extruding tubes used for vehicle components with 50 to 100 percent greater ductility and energy absorption over conventional extrusion technologies, while dramatically reducing manufacturing costs.

DIAMINE SOLVENT SYSTEM FOR CO2 CAPTURE (iEdison No. 0685901-18-0018)
We have developed a novel solvent system comprising of diamine molecules and ether functionality that have the lowest CO2rich viscosity of any known concentrated amine based capture solvents. Additionally, these solvents do not undergo hydrolysis and disproportionation like closely related aminosilicone General Electric (GE)solvents. Most amine-based capture solvents require co-solvent in order to lower viscosity or dissolve solid carbamates formed upon CO2 capture, this invention eliminates the need for co-solvents. These diamine solvents developed at PNNL in collaboration with GE have shown CO2-rich viscosity of 43 cP at 50 mol% loading. The diamine solvent has shown good recyclability over five CO2addition and stripping cycles and thermal stability, which makes it good candidate for keeping overall solvent costs low.
Solid Phase Joining of Dissimilar Material Extrusions in a Butt Weld Configuration
Shear assisted processing and extrusion (ShAPE (Trademark) ) will be used to join dissimilar materials such as magnesium and aluminum alloys in a butt joint configuration. Combinations of 2XXX, 6XXX, and 7XXX aluminum or other alloys or other materials could also be joined in extruded form. Because joining will occur in the solid-phase and in the presence of extreme shear ,the joint composition will transition gradually from one material to another which will improve mechanical properties compared to conventional fusion welding. This a solution for joining extruded materials such as Mg-Al and precipitation hardened high strength aluminum alloys which are not readily joined by fusion welding. This new joining concept builds upon recent discoveries, and years of experience, gained using ShAPE (Trademark) to extrude magnesium and aluminum alloys. This concept is an entirely new joining method.

CAPTURE AND RELEASE OF ACID GASSES USING TUNABLE ORGANIC SOLVENTS WITH AMINOPYRIDINE
A class of water lean, organic solvents that can bind with various acid gasses to form acid gas bound molecules having a high degree of intramolecular hydrogen bonding which enables their use as regenerable solvents for acid gas capture. Unlike the other devices described in the prior art, the present invention takes advantage of shortened distances between the portions of the molecule that form hydrogen bonds within the structures when loaded with an acid gas so as to create a molecule with a higher internal bonding affinity and a reduced proclivity for agglomeration with other molecules.
METHODS AND DATA STRUCTURES FOR EFFICIENT CROSS-REFERENCING OF PHYSICAL-ASSET SPATIAL IDENTIFIERS
The invention is the reference implementation of the Unique Building Identifier (UBID) specification [1]. The reference implementation includes the "buildingid" command-line executable that supports comma-separated values (CSV) files and Environmental Systems Research Institute (ESRI) Shapefiles and provides UBID encoding and decoding, UBID cross-reference and CSV file to/from ESRI Shapefile conversion capabilities. A UBID is a short string of characters (typically, less than 24 characters) that encodes of the center of mass (i.e., centroid) and cardinal direction extents of a land lot on the surface of the Earth. Examples of land lots include building footprints. The input for encoding a UBID is 6 numbers: the latitude and longitude coordinates of the centroid of the land lot and the latitude and longitude coordinates of the south-west and north-east corners of the minimal bounding box of the land lot. In the UBID specification, latitude and longitude coordinates are encoded as short strings using the Open Location Code (OLC) grid reference system [2]. The OLC grid is a recursively-subdivided, rectangular grid. At each level of the recursion, the grid has higher resolution. For example, in the 5th layer, the area of each OLC grid cell is approximately 14x14 meters (at the Equator). The OLC grid also has a "refinement" capability. For example, in the 5th layer with 1 refinement, the area of each OLC grid cell is approximately 2x3 meters (at the Equator). The inventive feature of UBID is that the extents of the OLC grid cell are used to measure the cardinal direction extents of the land lot. In the UBID specification, each extent is the smallest number of OLC grid cells that are required to completely cover a given line. For example, the line from the northern edge of the OLC grid cell to the northern edge of the minimal bounding box of the land lot. (In fact, the selection of OLC is arbitrary. The UBID methodology being applicable to any rectangular grid reference system with a string representation for latitude and longitude coordinates.) Since extents are measured "OLC grid cell units," the UBID specification is robust with respect to the underlying geographic coordinate system (in this case, WGS-84) and its behavior with respect to the position of a given land lot on the surface of the Earth (e.g., at the poles). UBIDs can be assigned to any land lot. (In fact, UBIDs can be assigned at any location rectangle, including those at sea!) One land lot can be assigned multiple UBIDs, where each UBID is dependent upon the OLC resolution. Hence, the OLC resolution itself can be selected with respect to the requirements of each use case. The UBID cross-reference capability of the "buildingid" command-line executable can be used to decide if two UBIDs are assigned to the same land lot or if two UBIDs have an "intersects" and/or "contains"/"within" relationship.
