Method for Preparing Battery-grade Anhydrous Iron Phosphate from Liquid Crude Monoammonium Phosphate
Publication number: 20240101424Abstract: The present invention provides a method for preparing battery-grade anhydrous iron phosphate from liquid crude monoammonium phosphate, and belongs to the technical field of chemical industry production. In the present invention, ferrous sulfate solution and liquid crude monoammonium phosphate are used as raw materials, and ferrous iron is oxidized to ferric iron and separates out iron phosphate precipitate under the action of an oxidizing agent to obtain iron phosphate intermediate slurry; and then battery-grade anhydrous iron phosphate is finally obtained through solid-liquid separation, washing, aging, solid-liquid separation, washing, drying, dehydration and breaking up. The method provided by the present invention realizes the resource utilization of liquid crude monoammonium phosphate, has simple process and convenient operation and produces less waste water.Type: ApplicationFiled: February 21, 2023Publication date: March 28, 2024Applicant: Sichuan UniversityInventors: Xiaodong Guo, Zhenguo Wu, Yang Song, Tongli Liu, Fa He, Meng Xiao -
Patent number: 11555742Abstract: Systems for confocal Raman spectroscopy of points of interest or regions of interest with concurrent imaging are disclosed. The imaging may be used for real time selection of points of interest or regions of interest for Raman spectroscopy and to monitor for unwanted motions of a sample while Raman spectra are acquired. Disclosed embodiments apply Reflectance confocal microscopy (RCM) in a confocal Raman spectroscopy system. A single laser may be used as a light source for both RCM and micro-Raman spectroscopy. A Faraday optical isolator may be applied to extract RCM signals for imaging Systems as described herein have example application for ex vivo sample and in vivo skin measurement.Type: GrantFiled: September 4, 2019Date of Patent: January 17, 2023Assignee: Provincial Health Services AuthorityInventors: Zhenguo Wu, Haishan Zeng, Jianhua Zhao, Liwei Jiang

Publication number: 20220015638Abstract: Methods and apparatus for obtaining 3D imaging of tissue involve scanning a focused laser beam in xz planes to obtain a set of xz plane images spaced apart in a y direction. The xz plane images are processed to correct distortions and motions and combined to provide 3D image data. Surface flatting is optionally performed. Imaging may be performed using a femtosecond (fs) laser beam. Different components of light returning from the tissue may be detected and processed to yield plural co-registered images using different imaging modalities, for example, reflective confocal microscopy (RCM), two photon fluorescence (TPF) and second harmonic generation (SHG).Type: ApplicationFiled: November 22, 2019Publication date: January 20, 2022Inventors: Haishan ZENG, Zhenguo WU, Harvey LUI, Yunxian TIAN
