Research on carbon black and Cerium co-doped Ti4O7-CB-Ce electrocatalytic oxidation of tetracycline-based antibiotics.

Abstract Elemental doping is a promising way for enhancing the electrocatalytic activity of metal oxides. Herein, we fabricate Ti/ Ti₄O₇-CB-Ce anode materials by the modification means of carbon black and Cerium co-doped Ti₄O₇, and this shift effectively improve the interfacial charge transfer rate of Ti₄O₇and •OH yield in the electrocatalytic process. Remarkably, the Ti₄O₇-CB-Ce anode exhibits excellent efficiency of minocycline (MNC) wastewater treatment (100 % removal within 20 minutes) and the removal rate reduces from 100 % to 98.5 % after 5 cycles, which is comparable to BDD electrode. •OH and ¹O₂ are identified as the active species in the reaction. Meanwhile, it’s discovered that Ti/ Ti₄O₇-CB-Ce anodes can effectively improve the biochemical properties of the non-biodegradable pharmaceutical wastewater (B/C values from 0.25 to 0.44) and significantly reduce the toxicity of the wastewater (luminescent bacteria inhibition rate from 100 % to 26.6 %). This work paves an effective strategy for designing superior metal oxides electrocatalysts.

Fast target recognition and location based on graph model and point cloud model

Journal of Physics Conference Series (2021)

Yuntao Zhao Jiaming Hu Weigang Li

Abstract When using the point cloud model to identify and locate the target, there are some problems, such as low recognition accuracy and slow positioning speed. In order to solve these problems, this paper proposes a fast target recognition and location method based on point cloud model and graph model, which combines the characteristics of graph model processing speed, algorithm efficiency and recognition accuracy. Through the analysis of the characteristics of the target graph model, the pixel coordinates and rotation angle of the target grabbing points are calculated. After the transformation matrix and mapping relationship, the spatial coordinates of the point cloud model are obtained. The efficiency and accuracy of the method are verified by the recognition and positioning experiments on the robot target grabbing platform.

Research on Cb-Ce Co-Doped Ti4o7 Electrocatalytic Oxidation of Tetracycline-Based Antibiotics

Elemental doping is a promising way for enhancing the electrocatalytic activity of metal oxides. Herein, we fabricate Ti/ Ti4O7-CB-Ce anode materials by the modification means of CB and Ce co-doped Ti4O7, and this shift effectively improve the interfacial charge transfer rate of Ti4O7 and •OH yield in the electrocatalytic process. Remarkably, the Ti4O7-CB-Ce anode exhibits excellent efficiency of minocycline (MNC) wastewater treatment (100 % removal within 20 minutes) and its cycling stability is comparable to BDD electrode. Meanwhile, it’s discovered that Ti/ Ti4O7-CB-Ce anodes can effectively improve the biochemical properties of the non-biodegradable pharmaceutical wastewater (B/C values from 0.25 to 0.44) and significantly reduce the toxicity of the wastewater (luminescent bacteria inhibition rate from 100 % to 26.6 %).

Prediction and Control Technology of Stainless Steel Quarter Buckle in Hot Rolling

Metals (2020)

Hui Li Chihuan Yao Jian Shao Anrui He Zhou Zhou

To obtain the good flatness of hot-rolled stainless-steel strips, high-precision shape control has always been the focus of research. In hot rolling, the quadratic wave (centre buckle and edge wave) can usually be controlled effectively. However, the quarter buckle of the strip is still a challenge to solve. In this paper, a prediction model of roll deflection and material flow is established to study the change rule and control technology of the quarter buckle. The effects of the process parameters on the quarter buckle are analysed quantitatively. The process parameters affect the quarter buckle and the quadratic wave simultaneously. This coupling makes the control of the quarter buckle difficult. The distribution of lateral temperature and the quartic crown of the strip have less effect on the quadratic wave but have a great effect on the quarter buckle. Finally, a new technology for work roll contour is developed to improve the quarter buckle. Through industrial application, the model and the new contour are proved to be effective.

Improved algorithm for load distribution in the rolling force mode for hot strip mills

Baosteel Technology (2012)

Weigang Li

To overcome the defect of the draft ratio distribution method,Baosteel plans to develop a new distribution method in the rolling force mode in its 1 580 mm process control system reconstruction project.Because the conventional Newton-Raphson algorithm has the defects such as too much dependence on the initial value and algorithm divergence,an improved algorithm for load distribution in the rolling force mode has been presented.The new algorithm has taken the rolling draft of each finishing mill stand as the decision variable.Non-linear equations have been established based on the proportional principle of the rolling force distribution.The coefficient matrix has been reduced to a diagonal matrix by mathematical derivation,so that matrix inversion can be avoided.In order to meet the constraint that the sum of rolling drafts of all stands should be equal to zero,a correction item has been added to the draft iterative correction for an overall coordination and a process procedure for rolling force or draft overload has been presented.The simulation experiments have proved the validity of the new algorithm,which can be applied to on-line pass schedule calculation.It has advantages such as fast computing and excellent convergence performance.
