This review presents a summary of the research conducted thus far on the recovery of various types of valuable metals from red mud. The composition, properties, environmental hazards, and current status of comprehensive utilization of red mud were studied. A number of studies have been conducted on the use of red mud as a modifying additive for cement, the development of various catalysts based on red mud, and the recovery of various valuable metals from red mud. Furthermore, we examine several techniques for extracting various types of valuable metals from red mud, including pyrometallurgical recovery, wet leaching recovery, and emerging biobased technology recovery. We investigate the underlying principles, processes, research progress, and the potential for industrial application of these methods, and assess the advantages and disadvantages of each from the perspectives of economic and environmental benefits. Although these methods have certain disadvantages, in general, the recovery of various types of valuable metals from red mud is an effective way to solve the problem of red mud and the supply of metal raw materials. In conclusion, this paper presents an overview of the current state of red mud development and utilization, as well as the various methods employed for the recovery of valuable metals from red mud.

Dear Editor,This letter studies the bipartite consensus tracking problem for heterogeneous multi-agent systems with actuator faults and a leader's unknown time-varying control input. To handle such a problem, the continuous fault-tolerant control protocol via observer design is developed. In addition, it is strictly proved that the multi-agent system driven by the designed controllers can still achieve bipartite consensus tracking after faults occur.

由于硅纳米谐振器在量子计算、传感器、医学等方面存在广泛的应用,使其物理性质的研究具有重要意义.本文通过分子动力学模拟方法研究了掺杂元素、空位缺陷、掺杂浓度对单层硅烯纳米梁振动特性的影响.研究结果表明,单层硅烯纳米梁的振动频率随着纳米梁长度的增加而减小.单元素、双元素掺杂均会导致单层硅烯纳米梁的振动频率的增加,且随着掺杂浓度的增加纳米梁的振动频率整体呈现增大的趋势.此外,单空位缺陷会导致单层硅烯纳米梁的振动频率随着缺陷浓度的增加而减小.掺杂-单空位缺陷的单层硅烯纳米梁的振动频率则呈现了随着掺杂浓度的增加先减小后增加的变化趋势.这些变化规律均是由掺杂元素、空位缺陷以及它们共同作用的结果.此研究结果对硅烯纳米谐振器,振荡器等纳米器件的设计具有一定的理论指导意义.

Journal of Harbin Institute of Technology(New Series) 2014年第2期21卷 75-82页

作者： Wei-Guo Wu wen-Qian du Humanoid and Gorilla Robot & Its Intelligent Motion Control Lab Harbin Institute of Technology

The concept of legged-robot stability training with a training platform is proposed and a serial-parallel mechanism platform with 6 degrees of freedom is designed for this target. The designed platform is composed of 4-DOF parallel mechanism with spherical joints and prismatic pairs,and 2-DOF serial mechanism with prismatic pairs. With this design,the platform has advantages of low platform countertop,big workspace,high carrying capacity and high stiffness. On the basis of DOF analysis and computation of space mechanism,weight supporting auxiliary mechanism and raceways-balls supporting mechanism are designed,so as to improve the stiffness of designed large platform and payload capacity of servo motors. And then the whole structure design work of the platform is done. Meanwhile,this paper derives the analytical solutions of forward kinematics, inverse kinematics and inverse dynamics. The error analysis model of position and orientation is established. And then the simulation is done in ADAMS to ensure the correctness and feasibility of this design.
