    Abstract: Sinter-resistant catalyst systems include a catalytic substrate comprising a plurality of metal catalytic nanoparticles bound to a metal oxide catalyst support, and a coating of oxide nanoparticles disposed on the metal catalytic nanoparticles and optionally on the metal oxide support. The oxide nanoparticles comprise one or more lanthanum oxides and optionally one or more barium oxides, and additionally one or more oxides of aluminum, cerium, zirconium, titanium, silicon, magnesium, zinc, iron, strontium, and calcium. The metal catalytic nanoparticles can include ruthenium, rhodium, palladium, osmium, iridium, and platinum, rhenium, copper, silver, and/or gold. The metal oxide catalyst support can include one or more metal oxides selected from the group consisting of Al2O3, CeO2, ZrO2, TiO2, SiO2, La2O3, MgO, and ZnO. The coating of oxide nanoparticles is about 0.1% to about 50% lanthanum and barium oxides. The oxide nanoparticles can further include one or more oxides of magnesium and/or cobalt.

    Abstract: A method in a multiprocessor system for processing multiple perception streams is disclosed. The method comprises: reading data from a plurality of perception streams according to a reading schedule determined by a predetermined policy, each perception stream comprising perception data from a different perception sensor; assigning a unique identification tag to each perception stream; writing each perception stream with its unique identification tag to a server input queue based on the predetermined policy; and processing the tagged perception streams using a server. The processing includes: retrieving tagged perception streams from the server input queue; applying a processing algorithm to process the retrieved tagged perception streams; and outputting the processed perception streams to a server output queue. The method further includes retrieving the processed perception streams from the server output queue and dispatching each retrieved processed perception stream to an appropriate post-processing destination based on the tag associated with the retrieved processed perception stream.

    Abstract: Vehicles and methods are provided for monitoring the health of a substrate and a protective coating disposed on the substrate. A vehicle includes a substrate, a protective coating, a coating deformation sensor, and a controller. The protective coating is disposed overtop the substrate. The coating deformation sensor is operatively coupled with the protective coating and configured to measure a deformation value of the protective coating. The controller is configured to: determine a deformation recovery rate of the protective coating based on the deformation value; determine whether the deformation recovery rate corresponds with an expected recovery rate of the protective coating; and indicate that the protective coating may be impaired in response to determining that the deformation recovery rate does not correspond with the expected recovery rate.

    Abstract: Catalysts that are resistant to high-temperature sintering and methods for preparing such catalysts that are resistant to sintering at high temperatures are provided. The catalyst may be prepared by contacting a solution comprising an ionic species with one or more charged surface regions of a catalyst support. A surface of the catalyst support further includes one or more catalyst particles disposed adjacent to the one or more charged surface regions. The ionic species has a first charge opposite to a second charge of the one or more charged surface regions. Next, the ionic species is associated with the one or more charged surface regions to form a layer on the one or more select surface regions. The layer is calcined to generate a coating comprising metal oxide on the one or more select surface regions, where the coating is formed adjacent to the one or more catalyst particles.
