MATERIAL SEPARATING ASSEMBLIES AND METHODS (iEdison No. 0685901-22-0268)
Here we disclose a Boycott Separator to separate, dilute/concentrate, or remove particles from flows. To perform particle separations, this new class of separators uses the Boycott effect, in which which settling particles interact with an angled surface to accelerate particle motion toward the bottom of the channel. Here the angled surface is oriented with at least partially with some orthogonality with respect to the flow. Fin arrangements of such surfaces are also disclosed. Numbering up of such surfaces or fins is also disclosed. We also disclose a shallow angle of entry to minimize the length of the device by eliminating recirculating entry zones. Please see subsequent sections for history, problem, relative advantages, etc.

METHODS, SYSTEMS, AND COMPUTER-READABLE STORAGE MEDIA FOR ENHANCED PHASE-CONTRAST X-RAY IMAGING
This invention is a test object for phase contrast x-ray imaging, which is used to test that artifacts which may adversely affect the scatter measurement have been properly removed. The test object consists of three or more materials which are homogeneous, with no large density variations on length scales between 10 nm and 200 microns, and represent a range of atomic numbers. The materials are machined to a thickness suited to the energy of the x-rays used, such that 10-90% of the beam intensity is transmitted through the object. A phase contrast measurement is performed, with corrections for spurious signals due to spectral changes during attenuation, and the resulting scatter image of the test object will be consistent with background if the correction is successful.
METHODS AND TOOLS FOR FRICTION EXTRUSION OF COMPOSITE EXTRUDATES (iEdison No. 0685901-22-0003, ARPA-E)
Sponge iron is an intermediate product from direct reduction ironmaking (DRI) process, which has much lower carbon emission compared with conventional blast furnace ironmaking. In currently steel industry process, sponge iron is fed into electric arc furnace (EAF) to be melted, purified, followed with addition of alloying elements, including carbon, to make steels. We demonstrate the process of directly making Fe-based alloys from sponge iron without adding greenhouse gas-emitting ingredient, namely carbon and its associated products. In addition, such process will eliminate the energy-intensive melting step in steelmaking, saving energy and indirectly reduce emission. Such process also takes advantage of wastes in steelmaking process, namely SiO2 and Al2O3 impurities contained in iron ore, and incorporates them as strengthening phases in so-produced Fe-based alloys.
Framework for Network Co-Simulation (FNCS) 2.0 (Open Source)
FNCS 2.0 is a brand new implementation of the concepts established by FNCS 1.0 (https://github.com/GridOPTICS/FNCS). Cooperative simulation, or co-simulation, is the process in which at least two simulators solve initial-value differential equations that are coupled to each other. Data is exchanged at fixed time steps and no iteration is allowed between simulators to converge to a solution at any particular time step. In literature, this type of co-simulation is referred to as quasi-dynamic coupling, loose coupling, or Ping-Pong coupling (Hensen 1999, Zhai and Chen 2005). FNCS 1.0 extended these concepts by allowing variable time steps and speculative synchronization. FNCS 2.0 extends these concepts further by allowing simulators to reiterate during synchronization points. FNCS 2.0 also distills the concepts of FNCS 1.0 down to a simple, yet powerful, application programmer interface library.
