Publication number: 20240262700Abstract: A selective postsynthetic surface modification process of mesoporous Y zeolite (Meso-Y) is provided. The process results in a thin silica, alumina or aluminosilicate overlayer on the external surface without causing significant pore blockage, which otherwise results in the absence of surfactant. The approach relies on occluded CTAB surfactant in as-synthesized Meso-Y acting as a soft template, which protects internal microporosity and mesoporosity during inorganic overlayer synthesis, by directing its deposition to selectively occur on the external surface. The process is conducted under dry conditions.Type: ApplicationFiled: February 5, 2024Publication date: August 8, 2024Applicants: Chevron U.S.A. Inc., The Regents of the University of CaliforniaInventors: Alexander KATZ, Le XU, Alexander OKRUT, Alexander KUPERMAN

Publication number: 20190370408Abstract: Mechanisms to modify a dataflow execution graph that processes a data stream. An intermediate dataflow execution graph is used during modification of the dataflow execution graph from one configuration (the old dataflow execution graph) to the next (the new dataflow execution graph). Data messages of the data stream may continue to feed into the intermediate dataflow execution graph, thereby reducing latency and maintaining throughput during reconfiguration of the dataflow execution graph. Control message(s) that are structured to accomplish the reconfiguration is/are also passed into the intermediate dataflow execution graph during reconfiguration. As the control message(s) are all processed by the intermediate dataflow execution graph, the intermediate dataflow execution graph assumes the topology of the new dataflow execution graph.Type: ApplicationFiled: May 31, 2018Publication date: December 5, 2019Inventors: Rahul POTHARAJU, Kai ZENG, Paolo COSTA, Terry Yumin KIM, Sudheer DHULIPALLA, Saravanan MUTHUKRISHNAN, Shivaram VENKATARAMAN, Le XU, Lao MAI, Steve D.
