Patent number: 11952298Abstract: A method for deodorizing sludge with a metal salt and a tannin extract together, deodorized sludge, and use thereof are provided. The present invention provides a sludge deodorization technology that has high treatment efficiency, environmental friendliness, and low investment costs, and satisfies harmless requirements of subsequent resource utilization such as incineration, pyrolysis, or carbonization. Characterized by containing abundant phenolic hydroxyl groups, the tannin extract is used as a multidentate ligand to undergo a complexation reaction with metal ions, which reduces bioavailability of proteins and other macromolecules, and effectively inhibits production of low-volatile sulfides, thereby significantly deodorizing the sludge during standing and combustion.Type: GrantFiled: October 15, 2021Date of Patent: April 9, 2024Assignee: FUZHOU UNIVERSITYInventors: Minghua Liu, Jiantao Lin, Shuyu Jiang, Yuchuan Yang, Yuxin Zhou, Yifan Liu

Patent number: 11036004Abstract: A compact, low-loss and wavelength insensitive Y-junction for submicron silicon waveguides. The design was performed using FDTD and particle swarm optimization (PSO). The device was fabricated in a 248 nm CMOS line. Measured average insertion loss is 0.28±0.02 dB across an 8-inch wafer. The device footprint is less than 1.2 ?m×2 ?m, orders of magnitude smaller than MMI and directional couplers.Type: GrantFiled: December 10, 2018Date of Patent: June 15, 2021Assignee: Nokia Solutions & Networks OyInventors: Yang Liu, Yangjin Ma, Ruizhi Shi, Michael J.

Publication number: 20190181612Abstract: A hybrid single or multi-wavelength laser using an optical gain element, such as a semiconductor optical amplifier (SOA), for example a QD RSOA, and a semiconductor, e.g. silicon, photonics chip is demonstrated. A plurality, e.g. four, lasing modes at a predetermined, e.g. 2 nm, spacing and less than 3 dB power non-uniformity may be observed, with over 20 mW of total output power. Each lasing peak can be successfully modulated at 10 Gb/s. At 10?9 BER, the receiver power penalty is less than 2.6 dB compared to a conventional commercial laser. An expected application is the provision of a comb laser source for WDM transmission in optical interconnection systems.Type: ApplicationFiled: February 22, 2019Publication date: June 13, 2019Applicant: Elenion Technologies, LLCInventors: Yi Zhang, Shuyu Yang, Michael J.
