The lecture commenced with a welcome speech and speaker introduction by Ir Prof. MAN Hau-chung, Dean of Faculty of Engineering and Director of the Research Institute for Advanced Manufacturing (RIAM). In Prof. Lin presentation, he primarily indicated the increasing global requirements for reducing energy use and carbon dioxide emission of transportation vehicles, lightweight passenger cars have become an inevitable trend. Ultra-high strength steel (UHSS) can save the production cost of vehicles, improve productivity and car performance. Next, he introduced the “HFQ®-Technology” developed by his team in recent years that has enabled high strength alloys to be stamped into complex-shaped automotive components. He outlined the use of thermomechanical experimental tests for generating high quality data for modelling, and the use of spatio-temporal method for determining necking and fracture strains of sheet metals. He also explained the computational steps for evaluating the formability of sheet metals under hot stamping. To conclude, Prof. Lin emphasised that improvements in experimental sciences, technologies and standardised testing are important for supporting the development of new materials processing technologies.

Smaller, faster-charging batteries are the answer for affordable and sustainable electric vehicles (EVs) for everyone, everywhere. The ability to quickly refill energy is profoundly important in order to reduce EV cost and demand for critical minerals. In this talk I will present asymmetric temperature modulation (ATM) approach to enabling 10-minute fast charging of energy-dense Li-ion batteries in any temperatures (even at -60°C) while still delivering remarkable cycle life. Recent disastrous events at EV charging stations caused by an arctic blast in Chicago will be given as an example of the dire need for quick energy refill in the extreme cold. Battery fast charging must also work in hot summers along with high-temperature stability of cycling and storage. We shall present novel thermal management concepts for extreme fast charging in both extreme cold and hot conditions. Overall, our development points to a new paradigm of battery design and thermal management without having to trade-off among fast charge, safety, lifetime, and cost.

The lecture commenced with a warm welcome address by Prof. CHEN Qingyan, Director of PAIR, followed by a brief speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation) of PolyU. In his presentation, Prof. Yang highlighted that urgent need for tissue/organ biomanufacturing owing to the shortage of donation for organ transplantation. He pointed out some challenges in the in vitro manufacturing of tissues/organs, particularly in relation to accurate design, precise fabrication, and functional induction, which underscore the imperative need for new methods for tissue/organ manufacturing. Next, Prof. Yang outlined the development roadmap of biomanufacturing and shared specific examples demonstrating the research progress in 3D bioprinting. In concluding his presentation, Prof. Yang shared his insights on the future direction for biomanufacturing, as well as some significant accomplishments by him and his team at Zhejiang University in the field.
A question-and-answer session moderated by Prof. Wang was followed. Both the online and on-site audience had a fruitful discussion with Prof. Yang.

PAIR distinguished lecture series: an overview of high performance computing and future requirements
In this talk, we examine how high performance computing has changed over the last ten years and look toward the future in terms of trends. These changes have had and will continue to impact our numerical scientific software significantly. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic, distributed, and parallel environments. Some of the software and algorithm challenges have already been encountered, such as the management of communication and memory hierarchies through a combination of compile-time and run-time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run-time environment variability will make these problems much harder.

Overcoming the COVID-19 pandemic, public interests for healthcare innovations significantly increase. In order to prepare the next pandemic, POSTECH is initiating a new engineering-based medical school. This new program aims to solve practical medical problems via innovative technology and put significant efforts for commercialisation. As a Program Chair for the new Medical Science and Engineering Program, I will share my experience and future plans. Further, we spin-off a start-up company, “Opticho”, from the research outcomes in my lab. I will share my experience how translate the lab toys to commercial products: not only excitement but also difficulty.

Water shortage is one of the biggest challenges that humanity faces. Novel technologies to tackle the challenge of water scarcity are urgently needed. However, all the existing studies are based on bare fibers with diameter in the order of mm. This talk introduces a novel fog collection technology using microfibers fabricated by near-field electrospinning. The collection efficiency reaches a record high level. Systematic investigation reveals that the waterdrops are “visible” to fog droplets in the incoming air flow because of the relatively small size of the microfibers. Thus, the large waterdrops deflect the fog-carrying airflow to the satellite small waterdrops, which effectively intercept the fog droplets.
