Establishment of Biel-PolyU Glass Research Joint Laboratory

Dr Ruan Haihui, Associate Professor of the Department of Mechanical Engineering at PolyU, has received an industrial support of 5 million HKD from the Biel Crystal (HK) Manufactory Limited for collaborative research on precision glass manufacturing. The upcoming technologies have called for more usage of curved cover glasses in many areas including smartphones, wearable electronics, VR/AR glasses, and electronic vehicles. Such needs stem from the fact that human-machine interfaces must be transparent and anti-scratch. While glass covers can be thermoformed to have curved profiles that suit such needs, precision glass thermoforming is still extremely difficult owing to various quality issues arising from the lack of detailed know-how of the manufacturing process and in-depth knowledge in glass science. In the past decade, the development of a manufacturing process for curved glass covers was extremely time-consuming and costly owing to enormous trials and errors; therefore, an upgrade to a computation-based process development protocol is urgently needed. To lay such a foundation for the industrial partner and the glass manufacturing industry, we establish the Biel-PolyU Glass Research Joint Laboratory (伯恩光學 - 香港理工大學玻璃研究聯合實驗室) to develop: computational models that predict stress buildup, relaxation, and deformation in chemical strengthening, computational protocols that assist the design of molds to compensate form errors due to shrinkage and chemical strengthening, and novel molding materials and mold manufacturing technology that keep the transparency of thermoformed glass and ensure high-volume production.

Prof. Wallace Leung's new book on nanofiber filter technologies published by Elsevier

Prof. Wallace Leung has recently written a new book, “Nanofiber filter technologies for filtration of submicron aerosols and nanoaerosols”, published by Elsevier, 2021.   More than 26 cities in the world have high PM2.5 with over 10,000 counts/cubic centimeter. Hong Kong is no exception due to severe pollution from traffic emissions and the transport of pollutants across the border. The aerosols are dominated by submicron aerosol sizes less than one micrometer/micron and nanoaerosols of less than 100 nanometers. Novel coronavirus (SARS-CoV-2 virus) leading to the COVID-19 pandemic that has paralyzed the entire world in magnitude far beyond anyone’s imagination is in the same size category. Unfortunately, failure to recognize one of the modes of transmission by air of the coronavirus and its variants by the health authorities, experts, and the General Public leads to widespread disease and deaths globally during the first half of 2020 and in some cases even as of today. The book provides strong definitive evidence collected worldwide on the air transmission mode of the virus from residence, hospitals to laboratories. The virus is 60-140 nanometers and when attached to a carrier, it can be easily airborne. The book also provides nanofiber technologies on how the airborne virus can be effectively filtered. The book is written in layman’s language in 14 chapters, 533 pages, covering “fundamentals, deeper understanding, technologies, and applications”, with questions and answers at the end of each chapter. It is suitable for 3rd and 4th year undergraduates, or graduate courses, with contents related to pollution control, aerosols, fluid engineering, material sciences and engineering, and health technologies. To date, it is the first and most comprehensive text on air filtration using nanofiber technologies.  Topic Coverage 4 areas are being covered in the book – Fundamentals, Deeper understanding, Technologies and Applications.

International Conference on Applied Nonlinear Dynamics, Vibration, & Control

The International Conference on Applied Nonlinear Dynamics, Vibration and Control (ICANDVC-2021) was initiated by the PolyU Department of Mechanical Engineering last year and successfully held in Zhuhai Charming Holiday Hotel during 23-25 Aug 2021.  The conference name abbreviation ICANDVC implies “I See AND We See” which is in line with its objective. Through exchange and collaboration, we advanced the interdisciplinary R&D in applied nonlinear dynamics, applied vibration analysis and design, and applied control theory and methods across the globe. This is also the very core R&D activity of the research group – Nonlinear Dynamics, Vibration and Control led by Dr Jing Xingjian. Amid the pandemic period, we however received some 200 paper submissions and over 150 registrations for the conference. Among the submissions, 88 papers were selected to publish in a Springer proceedings book “Advances in Applied Nonlinear Dynamics, Vibration and Control-2021” which was edited by Dr Jing and the other Co-chairs from Shanghai University and Nanjing University of Aeronautics and Astronautics. We had 10 invited sessions and 12 in-parallel sessions at the conference. There were 3 online and 3 onsite plenary speeches and 9 session keynotes covering all three main themes in nonlinear dynamics, vibration and control. Besides the on-site participants, we had more than 150 attendees from the Chinese mainland, Australia, the United Kingdom, Hongkong and other places via our synchronized online platform. As a conclusion of the conference, we had 12 best presentation paper awards based on onsite marking by Session Chairs from 12 parallel sessions, 7 best paper awards and several outstanding paper awards for recognizing the great efforts and engagements of the conference attendees.
