  • Publication number: 20240262700
    Abstract: 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.

  • Publication number: 20190370408
    Abstract: 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.
