Patent number: 11951461Abstract: A solid acid catalyst has a macropore specific volume of about 0.30-0.50 ml/g, a ratio of macropore specific volume to specific length of catalyst particles of about 1.0-2.5 ml/(g·mm), and a ratio of specific surface area to length of catalyst particles of about 3.40-4.50 m2/mm. The macropore refers to pores having a diameter of more than 50 nm. An alkylation catalyst is based on the solid acid catalyst and can be used in alkylation reactions. The solid acid catalyst and alkylation catalyst show an improved catalyst service life and/or trimethylpentane selectivity when used in the alkylation of isoparaffins with olefins.Type: GrantFiled: January 20, 2020Date of Patent: April 9, 2024Assignees: CHINA PETROLEUM & CHEMICAL CORPORATION, RESEARCH INSTITUTE OF PETROLEUM PROCESSING, SINOPECInventors: Yongxiang Li, Xuhong Mu, Chengxi Zhang, Hexin Hu, Qiang Fu, Xingtian Shu

Publication number: 20230182200Abstract: A microdroplet-based three-dimensional (3D) laser printing system, which includes a laser beam subsystem, a transparent donor substrate, voxel arrays, and the receiver substrate. By irradiating the voxel array with a pulsed laser beam deriving from the laser beam subsystem through the transparent donor substrate, the voxel array is melted and driven away from the transparent donor substrate to generate the ejecting microdroplet array and then deposited onto the receiver substrate. The 3D microstructure is printed in parallel by sequentially irradiating the voxel array and controlling the depositing locations of microdroplet arrays onto the receiver substrate. The system can avoid the satellite microdroplets generating, improve the printing efficiency and resolution, and obtain a wide process window.Type: ApplicationFiled: May 13, 2021Publication date: June 15, 2023Applicant: SHANGHAI JIAO TONG UNIVERSITYInventors: Yongxiang HU, Guohu LUO, Di WU, Yu ZHOU, Zhenqiang YAO

Patent number: 10775537Abstract: A remote sensing system includes a primary beam configured to carry orbital angular momentum and characterized by a mode number (m), with the mode number (m) being a non-zero integer. The primary beam is configured to be directed at a target. A photon sieve is configured to receive a secondary beam emanating from the target. The secondary beam at least partially includes a portion of the primary beam. The photon sieve includes a plurality of holes forming one or more respective spiral patterns. The quantity of the respective spiral patterns in the photon sieve corresponds to the mode number (m) of the primary beam. The plurality of holes may be configured to have a minimum diameter such that the minimum diameter is greater than a predefined wavelength of the primary beam. The respective spiral patterns extend between a respective first hole and a respective final hole.Type: GrantFiled: March 20, 2018Date of Patent: September 15, 2020Assignee: UNITED STATES OF AMERICA AS REPRESENTED BY THE ADMINISTRATOR OF NASAInventors: David G. MacDonnell, Wenbo Sun, Yongxiang Hu

Patent number: 10393863Abstract: A lidar system includes an optical transmitter having a laser light source that is configured to generate a beam of light that is azimuthally polarized or has Orbital Angular Momentum (OAM). The lidar system further includes an optical receiver having an optical sensor defining a focal plane. A photon sieve is configured to produce a ring pattern on the focal plane corresponding to a laser return signal. The ring pattern comprises azimuthally polarized or Orbital Angular Momentum (OAM) light that is transmitted by the transmitter and reflected towards the receiver. The photon sieve is also configured to cause stray light that is not polarized to produce a central region at the center of the ring pattern that is distinct from the ring pattern.Type: GrantFiled: September 19, 2016Date of Patent: August 27, 2019Assignee: UNITED STATES OF AMERICA AS REPRESENTED BY THE ADMINSTRATOR OF NASAInventors: Wenbo Sun, Yongxiang Hu, David G.
