Patent number: 12053746Abstract: The present application provides a high-gravity device for generating nano/micron bubble and a reaction system. In the device, the liquid phase is continuous phase and the gas phase is dispersed phase. A gas enters the interior of the device from a hollow shaft, and the gas is subjected to primary shearing under a shearing effect of aerating micropores to form bubbles; then, the bubbles rapidly disengage from the surface of a rotating shaft under the effect of the rotating shaft rotating at a high speed, and are subjected to secondary shearing under the high-gravity environment with the strong shearing force formed by the rotating shaft to form nano/micron bubbles. The device has the advantages of fastness, stability, and small average particle size. The average particle size of the formed nano/micron bubbles is between 800 nanometers and 50 microns, and the average particle size of the bubbles can be regulated in a range by adjusting the rotating speed of the rotating shaft.Type: GrantFiled: March 5, 2020Date of Patent: August 6, 2024Assignee: BEIJING UNIVERSITY OF CHEMICAL TECHNOLOGYInventors: Yong Luo, Di Wang, Guangwen Chu, Yachao Liu, Zhihao Li, Yong Cai, Haikui Zou, Baochang Sun, Jianfeng Chen

Publication number: 20240238747Abstract: The present invention discloses an immersion type rotating packed-bed reactor and an application thereof. A rotor filler is immersed in materials in the reactor; under the driving of the rotation of a rotor, the materials in the reactor form a loop; and when passing through the filler, the materials are fully sheared and dispersed into fluid micro-elements, so that the mass transfer rate and the reaction rate are increased. A feeding assembly simultaneously introduces materials of different phases to an inner edge of the rotor, a retaining ring and a baffle function to break a vortex, and a heat exchange assembly can maintain a system in a suitable temperature range. The present invention is suitable for heterogeneous systems such as a gas-liquid system and a liquid-liquid system. Compared with a conventional rotating packed bed, the material contact time is long, so that the reaction is more complete.Type: ApplicationFiled: July 1, 2022Publication date: July 18, 2024Inventors: Jianfeng CHEN, Guangwen CHU, Liangliang ZHANG, Baochang SUN, Haikui ZOU, Yong LUO

Patent number: 8000826Abstract: One embodiment of the present invention provides a system that predicts manufacturing yield for a die within a semiconductor wafer. During operation, the system first receives a physical layout of the die. Next, the system partitions the die into an array of tiles. The system then computes systematic variations for a quality indicative value to describe a process parameter across the array of tiles based on the physical layout of the die. Next, the system applies a random variation for the quality indicative parameter to each tile in the array of tiles. Finally, the system obtains the manufacturing yield for the die based on both the systematic variations and the random variations.Type: GrantFiled: January 24, 2006Date of Patent: August 16, 2011Assignee: Synopsys, Inc.Inventors: Jianfeng Luo, Subarnarekha Sinha, Qing Su, Charles C.
