Title: Materials and device designs for battery–supercapacitor hybrid energy storage devices
标题：用于电池 - 超级电容器混合能量存储装置的材料和装置设计
Abstract: Energy storage industry is becoming highly significantly in modern times as all nations are giving paramount importance to zero-emission and renewable technologies (synonymously called green technologies) and, consequently, electrically powering the devices and services. As a result, many new battery concepts such as sodium batteries, lithium-air, lithium-sulphur, and battery-supercapacitor hybrid (BSH) are currently under intensive research. Among them BSH is a promising technology owing to its high power density (≥5 kW/kg) and cycle life (>100,000) than batteries. In the BSH technology, a battery-type material take-up the positive electrode and electrochemical double layer (EDLC) capacitive (supercapacitive) material take-up the negative electrode, they make an interface with an electrolyte and they are separated by permeable membrane. There are a number of criteria the two types of electrodes, electrolytes, and separator must possess; having all these properties in a single material is limited by cost. In this research, cheap materials for the fabrication of BSH has been designed and developed: (a) nanofibers and nanobelts containing materials of different functionalities were designed as developed in large scales for battery-type electrodes; (b) pore-filled porous carbon with a conformal coating of pseudocapacitive materials are designed and developed as the supercapacitor electrodes; (c) electrolytes with tailored oxidation and reduction potentials are designed and developed; and (d) finally, porous membranes from local renewable sources (empty fruit bunch from oil palm industry) are designed and developed.1-7 Furthermore, BSH devices of industrial capacity has been designed from the above innovative materials. These design developments will be detailed in the lecture.

Title: Path Planning of Robot: Challenges, Unsolved Problems and Future Solutions
题目：机器人路径规划：挑战，未解决的问题和未来的解决方案
Abstract: Path planning in robotic research is one of the most complicated problems that can occur during autonomous navigation in unknown environments. In path planning approaches, the path trajectory is planned continuously between the start and goal positions while attempting to avoid colliding with obstacles and other objects within the path. Two kinds of path planning approaches for mobile robot have been established, namely the global and local path planning. In the former, the surroundings of the environments are totally known and the collision-free trajectory is usually accomplished off-line whereas in the latter, the surroundings of the environments are unknown and feedbacks from sensors are required for real-time path planning In general, the process of path planning involves three main tasks: (i) sketch clearly and informatively the robot’s terrain, (ii) determine the collision-free path from start to target points and (iii) seek for optimum path to reach the goal. The current path planning methods have been utilized widely to find the shortest path, optimum path to determine the goal, collision avoidance and collision-free path navigation in difficult environments. However, none of these approaches can be used effectively in constrained environments such as the road and factory settings, where there are some rules and constraints that must be strictly adhered. Owing to the constraints, current classical path planning algorithms are no longer suitable for path determination in the maps of the constrained environment. In addition, the generated path has to guarantee low computational and path costs, avoid obstacles and follow a smooth path to reach the goal.

Title:New Lightweight Materials For Automotive Application: Some Recent Developments And Potential Opportunities
题目：适用于汽车应用的新型轻质材料：最新发展与潜在机遇
Abstract: In recent years, magnesium (Mg) alloys have made inroads into applications in transportation industries. Lightweight alloys are being increasingly used for applications, such as automotive and aerospace industries, where weight savings are critical. Their favorable property profile promotes increased usage. Despite magnesium alloys being in service for years, there is still lack of knowledge on potential of Mg alloys. New or optimized alloys are inventing new ideas to to substitute traditional materials. Developments in the last decade have led to an improvement of the property profile and effectiveness of magnesium alloys. In order to develop new alloy to achieve higher strength to compete with currently used metal alloys, it is important to understand the effects of alloying elements on the microstructure and mechanical properties. Rare earth metals as alloying components in Mg alloys open new opportunities in tailoring of property profile and functionality. The strength of Mg alloys can be enhanced by adding proper amounts of certain alloying elements. This presentation will give an overview of the status of alloy development and discuss the challenges in extension of use of magnesium alloys.
