  • Publication number: 20220195549
    Abstract: Methods for forming carbon-based lubricious and/or wear-protective films in situ on the surface of steel alloys are provided. The methods use chromium-containing steel alloys, molybdenum-containing steel alloys, and steel alloys that contain both copper and nickel. When such alloys are subjected to a rubbing motion in the presence of a hydrocarbon fluid, the chromium, molybdenum, copper, and nickel in the steel alloy catalyzes the formation of solid carbon-containing films that reduce the friction, wear, or both of the contacting surfaces.

  • Publication number: 20220188264
    Abstract: An SoC maintains the full flexibility of a general-purpose microprocessor while providing energy efficiency similar to an ASIC by implementing software-controlled virtual hardware architectures that enable the SoC to function as a virtual ASIC. The SoC comprises a plurality of “Stella” Reconfigurable Multiprocessors (SRMs) supported by a Network-on-a-Chip that provides efficient data transfer during program execution. A hierarchy of programmable switches interconnects the programmable elements of each of the SRMs at different levels to form their virtual architectures. Arithmetic, data flow, and interconnect operations are also rendered programmable. An architecture index” points to a storage location where pre-determined hardware architectures are stored and extracted during program execution. The programmed architectures are able to mimic ASIC properties such as variable computation types, bit-resolutions, data flows, and amount and proportions of compute and data flow operations and sizes.

The heterocyclic derivative of Formula I has high electron mobility and great hole blocking performance, and thus the organic electroluminescent device prepared by using the heterocyclic derivative as the electron transport region material, especially the hole blocking material, has low drive voltage and high luminous efficiency. The organic electroluminescent device can also include a hole transport region, and the hole transport region, especially the emissive auxiliary layer, contains the triarylamine compound of Formula II. Since the electron transport region and the hole transport region of the device can effectively balance carriers, which reduces the quenching of excitons and improves the recombination probability of carriers, the device shows low drive voltage and high luminous efficiency.
