Vice President for International Affairs
Prof. Hsiao-Wei Yuan on International Collaboration in the Age of the Pandemic

Due to the impact of the COVID-19 pandemic and border control measures imposed by the CECC (Central Epidemic Command Center), most physical interactions between NTU and its international partners had to be suspended or postponed since the second semester of the 2019 academic year. According to Prof. Hsiao-Wei Yuan, Vice President for International Affairs, the sudden limitation of in-person exchanges in the international higher education system took the Office of International Affairs by surprise. However, solutions always emerge when there is a willingness to adapt, and NTU has responded with bold alternatives.

NTU and its partner institutions have brainstormed many innovative models to advance international collaboration. First of all, courses for international students are now offered online. Furthermore, the “COVID-19 Special Visiting Student Program” was launched for over 300 Taiwanese students who are not able to study abroad, allowing them to become visiting students while still at NTU.

With the vaccination program, border controls are gradually being loosened worldwide. During the 2021 academic year, many NTU students have embarked on exchange programs abroad. Prof. Yuan has urged the government to loosen border control measures as vaccine coverage increases so that more foreign students can come to Taiwan, revitalizing international exchange in higher education.

While many barriers have arisen in response to the pandemic, it has also brought unexpected benefits. For example, advances in video conference software and equipment have made online meetings the new norm, enhancing efficiency in communicating with our partner institutions. International seminars now utilize a hybrid format with local participants attending in person while those overseas join online. To accommodate students in different time zones, class lectures and discussions are recorded and uploaded to the NTU teaching platform, NTU COOL, for maximum flexibility. Moreover, NTU has collaborated with the Association of East Asian Research Universities (AEARU) in developing the “Global Learning Initiatives Program (GLIP),” so that students may take advantage of an international environment and collaborative resources as they learn together.

For Prof. Yuan, crisis is opportunity. It is true that the pandemic has greatly impacted regular international exchange, but it has also revealed NTU’s incredible ability to adapt and grow during a crisis.

ACHIEVEMENTS

Beyond 2nm Technology Nodes: The Tallest Transistor in the World

Prof. Chee Wee Liu and his research team at TSMC-NTU Joint Research Center conduct experiments on technology nodes beyond 2nm. The team’s latest findings were published in the 2021 IEEE VLSI Symposium on Technology and Circuits (VLSI) as the highlight paper. Their work also appeared in the Research Highlights section of Nature Electronics.

TSMC has used the high mobility channel (HMC) in the 5nm node. The HMC operates like a sports car that achieves the high speed with high horsepower, yielding a high-performance transistor. Samsung (3nm), Intel (2nm), and TSMC (2nm) take advantage of the gate-all-around (GAA) transistor structure for advanced technology nodes. The GAA structure is like a powerful, no-leak faucet, providing the transistor with low leakage current to save energy. Moreover, the GAA structure with channel stacking functions like a multi-level bridge which accommodates much more traffic flow than an ordinary single-level bridge. Therefore, the GAA structure with channel stacking provides large drive current for a given footprint to achieve high performance and area scaling (for example, Intel has 4 stacked channels and TSMC has 3 stacked channels). Consequently, the highly stacked GAA transistor with HMC is the key for advanced nodes.

In June 2021, Prof. Chee Wee Liu and his research team at National Taiwan University reported the first 7 stacked Ge0.95Si0.05 nanowires (figure 1) and 8 stacked Ge0.75Si0.25 nanosheets (figure 2) in VLSI 2021. Outside of industry, National Taiwan University is the only university with the ability to demonstrate highly stacked GAA transistors. The 7+ stacked Ge0.95Si0.05 nanowires are also named SpineFET due to their shape that resembles the human spine. The team’s drive current of 7 stacked Ge0.95Si0.05 nanowires was the highest achieved among reported Ge/GeSi 3D nFETs. The team’s results were also featured in the Research Highlights of Nature Electronics in July 2021.

Figure 2: 8 stacked Ge0.75Si0.25 nanosheets.

Prof. Chee Wee Liu and his research team remain dedicated to stacking more channels to achieve even higher drive current to improve chip performance. They have made significant progress working with the 16 stacked channels, and consider the 24 stacked channels
epitaxially possible.

NTU OLED Research Team Deciphers the Role of Host–Guest Interactions in Organic Emitters Using MR-TADF

A research team led by Prof. Pi-Tai Chou of the NTU Department of Chemistry has deciphered the role of host–guest interactions in organic emitters employing multiple resonance (MR)-thermally activated delayed fluorescence (TADF). Prof. Chou co-published the team’s finding with Profs. Wen-Yi Hung of National Taiwan Ocean University and Weiguo Zhu of Changzhou University in Nature Photonics, a finding which will have a far-reaching influence on the development of display technology.

Owing to their slight difference of charge separation, the emerging MR-TADF materials are superior to the standard TADF materials in terms of narrow emission bandwidth and high color purity. Also featuring high emission yield and metal-free organic properties, they have attracted considerable interest in the field of organic light emitting diodes (OLEDs) and the display industry. Despite MR-TADF’s favorable properties, researchers have puzzled over a mystery: several MR-TADF compounds demonstrate strong fluorescence upon photo-excitation but show no sign of delayed fluorescence.

To unravel the mystery, Prof. Chou’s team synthesized a series of novel MR-TADF molecules. They found that host and guest could interact to generate transient charge transfer intermediates. In turn, such intermediates could “bridge” the singlet and triplet states of the guest fluorescent molecules, thereby accelerating the rate of intersystem crossing and reverse intersystem crossing from singlet to triplet, as well as “creating” delayed fluorescence. Figure 1 shows how the formation of host-guest charge transfer intermediates accelerates the rate of the molecules’ intersystem crossing and reverse intersystem crossing to achieve TADF.

While preserving the purity of light and color, the guest/host transient interaction achieves efficient use of dark triplet state excitons. This new mechanism will enable OLED researchers to re-examine some singlet and triplet states whose energy gaps are small enough to be thermally activated, but which lack observable delayed fluorescent properties despite intense prompt fluorescence. Prof. Chou’s laboratory has set several milestones in the photophysics of organic and organometallic molecules. In the past four years, they published three original papers in the leading journal Nature Photonics, demonstrating significant results.

Bluefin Tuna Reveals Global Ocean Pollution and Cycling of Mercury

Bluefin Tuna (BFT), a fish species in high commercial demand, are known to accumulate mercury pollutants as neurotoxic methylmercury (MeHg) with age. BFT is an apex predatory and long-lived pelagic fish species, which migrates widely in the oceans and forages in different ranges of timing and locations. A mercury research team (hereafter Team Hg) led by Prof. Chun-Mao Tseng of the Institute of Oceanography, NTU (IO-NTU), initiated a new tool to measure the mercury accumulation rate (MAR) as a global barometer of Hg pollution and bioavailability in the world’s oceans.


Bluefin Tuna (BFT) reveal global patterns of Hg pollution and cycling in the world’s oceans.

Commenting on the research report, an anonymous reviewer said: “This paper provides a standard basis of comparison to examine spatial and temporal trends of Hg pollution across the world’s oceans using tuna fish as a biological indicator. This article answers the question we have been asking for 50 years: is there a relationship between the mercury accumulation in tuna fish and the MeHg content in seawater? Thus, it’s a breakthrough in understanding the Hg cycle in the oceans.”

Team Hg demonstrated that the MARs in BFT varied considerably, with the highest rates reported for BFT in the Mediterranean Sea, followed by the North Pacific Ocean, the Indian Ocean, and the North Atlantic Ocean, respectively. Moreover, the inter-basin variation in MARs among BFT populations is primarily controlled by the bioavailability of MeHg in seawater and the base of the food webs. Observed global patterns of MARs correspond to levels and inventories of MeHg in each ocean sub-basin, which are closely linked to Hg inputs into each ocean basin from both natural and anthropogenic emissions and global ocean circulation. Overall, variations in Hg bioaccumulation among Bluefin Tuna and other marine fish with widely dispersed populations could be used to help study global Hg pollution, manage marine fisheries, and provide a reference for human health guidelines.

Team Hg includes Prof. Jen-Chieh Shiao, Master’s student Yi-Sheng Chen, and research assistant Shin-Jing Ang of the IO-NTU, in collaboration with researchers from Rutgers University and University of California-Santa Cruz (UCSC), USA. This study was published in the prestigious Proceedings of the National Academy of Sciences (PNAS).

NTU Awarded for Inventing Solid-State
Na–CO2 Battery with High-Capacity Energy Storage and Carbon Neutral Application

Distinguished Professor Ru-Shi Liu of the Department of Chemistry received the 2021 Future Tech Award from the Ministry of Science and Technology for inventing the solid-state Na–CO2 battery with high-capacity energy storage and carbon-neutral application. The solid-state Na–CO2 battery is the first of its kind anywhere. (See Figure 1)

As countries worldwide become more environmentally conscious, research that promises energy savings and carbon reduction has attracted significant investments. The carbon dioxide battery has been a focus of research interest because it would produce electricity from the main greenhouse gas. Meanwhile, the price of lithium carbonate is soaring with the widespread use of lithium-ion batteries. As a result, the cheap and easily available sodium dioxide offers promise as an important replacement for lithium in batteries. In other words, the Na–CO2 battery promises the best of both worlds as it consists of greenhouse gas and cheap metal.

The Na–CO2 battery can be charged and discharged at room temperature. Moreover, since many countries are engaging in Mars explorations, demand exists for using Na–CO2 batteries in space.

The atmosphere of Mars is very different than the Earth’s atmosphere. Martian air consists of carbon dioxide (95.32%), nitrogen (2.7%), and argon (1.6%). Na–CO2 batteries could utilize the ample carbon dioxide in the Martian atmosphere to produce electricity to power the machines and equipment, manned or unmanned, used to explore Mars. Additionally, plans for Mars immigration would require electricity from carbon dioxide batteries. (See Figure 2)

While Na–CO2 batteries in organic liquid electrolyte form demonstrate excellent performance, they can precipitate explosions during chemical reactions. The solid-state Na–CO2 battery with high-capacity energy storage and carbon-neutral application shows great promise since it can be charged and discharged at room temperature. Under the conditions of a current density of 100 mA g-1 and a cut-off capacity of 500 mAh g-1, the battery can be cycled stably 105 times.

A patent is pending for the invention, and the research finding was published by Prof. Ru-Shi Liu et al. in “Na–CO2 battery with NASICON-structured solid-state electrolyte” (Nano Energy, March 16, 2021).

The event commenced with the rich, insightful presentations by Associate Professor Gina Wen-Chun Chen of National Chung Cheng University and Assistant Professor Keith M. Graham of National Taiwan Normal University. They offered practical tips for conducting English-instructed courses and ways to support students in an all-English classroom.

During the second session, Associate Professor Albert Y. Chen of the NTU Department of Civil Engineering, Distinguished Professor We-Fang Su of the NTU Department of Materials Science and Engineering, and Professor Helen K. Liu of the NTU Department of Political Science shared their EMI strategies and precious personal teaching experiences.

Finally, Associate Professor Heng-Tsung Danny Huang of the NTU Department of Foreign Languages and Literatures led a brainstorming session in which the participants openly discussed their frustrations and expectations about teaching in English. Participants shared observations on their EMI teaching experiences and also developed a list of useful resources.

To help elevate the level of English proficiency in Taiwan as well as promote English as a medium of instruction on campus, the NTU Center for Bilingual Education will remain dedicated to assisting faculty members by providing the insights and resources shared by experienced educators, practitioners, and researchers.

 


CBA’s Double Degree Program
Reaps Success

The College of Bioresources and Agriculture (CBA) boasts an unparalleled Master Double Degree Program supported by leading experts at leading universities, aimed to equip students with a solid interdisciplinary foundation. By partnering with prestigious agricultural universities in Japan, Indonesia, and France, the program offers students the opportunity to explore varied disciplinary perspectives as well as the experience of studying overseas through academic exchange or interdisciplinary academic collaboration.

The Master Double Degree Program was first launched in 2015 between NTU and the University of Tsukuba in Japan. Since then, the University of Brawijaya in Indonesia, Kyoto University in Japan, and the University of Bordeaux in France subsequently joined the program. To date, CBA has sent 14 NTU students to study abroad and welcomed 16 international students from its partner universities to study in the Departments of Agronomy, Bio-Mechatronics Engineering, Forestry, Plant Pathology and Microbiology, Animal Sciences and Technology, Agricultural Chemistry, Horticulture, and Biotechnology.

The number of international students decreased from 2020 when the pandemic broke out, and many students had to cancel their exchange plans due to safety concerns and mobility restrictions. Some students chose to continue their studies at home while others chose to stick with the original plan. For example, on one hand, two students from the University of Tsukuba and Kyoto University who had originally planned to study in Taiwan decided to stay in Japan, while two NTU students who were scheduled to begin their studies at Kyoto University in April 2021 decided to continue their dual degree program, on the other hand. Although the two NTU students were unable to attend the courses at Kyoto University in person, they completed the registration process and attended the lectures and experiments virtually under the guidance of their Taiwanese and Japanese supervisors.

Despite the many setbacks, this year CBA recruited its first double degree student from the University of Bordeaux, who enrolled in the Department of Agronomy in September. In the future, NTU will continue to promote the Master Double Degree Program and expand its partner university network so that students worldwide will have the opportunity to receive excellent multidisciplinary training at top-ranking institutions.



Journeying into Nature in the Classroom: Presentation of the Forest Adventure Virtual Reality Project

Associate Professor Chia-Pin YU of the Department of Forestry & Resource Conservation utilized VR technology to bring nature into the “Introduction to Forest Recreation” classroom in the spring semester of the 2020 academic year. Through this advanced technology, the students learned wilderness survival tips and observed wild animals from their desks in urban Taipei. The students were divided into 5 groups to prepare and present their term projects on September 13 in the Future Classroom. NTU President Chung-Ming Kuan, Vice President for Academic Affairs Shih-Torng Ding, and Vice President for International Affairs Hsiao-Wei Yuan attended their presentations and complimented the students on their efforts.

In order to promote the “Technology Enabled Active Learning (TEAL),” an innovative teaching approach, the Digital Learning Center of the Office of Academic Affairs has purchased 20 sets of VR equipment and assisted Prof. Yu in organizing the course. Prof. Yu had experienced courses using VR while serving as a visiting professor at Harvard University. He began to incorporate the technology in his courses at NTU with the support of Vice President for Academic Affairs Shih-Torng Ding.


The Epidemic Prevention Pack offered to international students in quarantine by the Office of International Affairs included the VR headset co-created by the Department of Forestry & Resource Conservation and HTC.

President Chung-Ming Kuan experienced VR technology.

Prof. Yu also worked with staff at the palliative care ward of Far Eastern Memorial Hospital in offering introduction to forest recreation to comfort the patients by transporting them into nature with VR. Since the technology has matured and is widely-used in research and teaching, he would like to develop its potential for educational purposes and train students to create VR content for NTU. With the assistance of the Digital Learning Center and HTC, the course combined VR with knowledge of forest recreation resources and outdoor safety. Prof. Yu expects that the VR content created by the students might be used to market forest recreation activities in the future.

With projects focusing on environmental education, wildlife, teaching materials for elementary/junior high school as well as virtual trips into nature, the course is a testament to the Digital Learning Center’s effort to promote digital instruction. The course received generous support from HTC both in procuring the VR equipment and hosting a 3-day workshop on recording and editing VR clips. It is anticipated that more faculty members will utilize VR to conduct cross-disciplinary teaching and facilitate cross-domain learning.

PEOPLE

Responsibilities of Social Media Platforms:
NTU Graduate Institute of Journalism Brings Different Players to the Table

Professors at NTU’s Graduate Institute of Journalism closely follow the issue of digital platform payment. For the Institute’s 30th anniversary symposium on November 12, they organized a dialog with representatives from such platforms as Facebook and Google to explore the possibility of digital platforms issuing payment to local news media outlets.

According to a Google survey, there are approximately 250 small and medium-sized media sources in Taiwan. Anita Chen, Google’s Head of Government Affairs and Public Policy in Taiwan, stated that Google does not make money through Google News. Rather, it hosts 24 billion views for the media per month. Maximilian Chen, the Public Policy Senior Manager of Facebook Taiwan, asserted that Facebook offers a free communication platform and referral traffic. It is up to the media sources whether they want to share news stories on Facebook.

Hsin-fang Wei, a commissioner of Taiwan’s Fair Trade Commission asserted that mainstream platforms, such as Google and Facebook, face little pressure from competition, and the monopoly or oligopoly situation is exacerbated by the rigid market structure. She further pointed out that online companies and news media compete for digital advertising, but the competitive positions of the two sides is asymmetrical. In her opinion, Taiwan needs laws and regulations to protect the media news sources by requiring search engines and platforms to pay them, and Article 25 of the Fair Trade Act might provide a basis for negotiations between the media and social platforms to this end.

Taiwan is not the first country to take up this issue; Australia and France reached agreements with Google and Facebook in 2021 requiring those companies to comply with regulations to pay for the news releases posted on their platforms. Professor Lih-Yun Lin, a commissioner of the National Communication Commission (NCC), confirmed that the NCC is looking into this issue and making efforts in support of legislation to require the digital platforms to issue payment to local news media in order to level the playing field.

Invitees from the government, industry, and academia discussed the current situation of news convergence, news crisis, and the turning point of journalistic practice, innovation, and reconstruction at the 30th Anniversary Symposium of the Graduate Institute of Journalism.



Keep it Flowing: NTU and Taipei City Government Restore Campus Canals

National Taiwan University joined hands with Taipei City Government in developing an amenity-oriented environment on NTU campus where people can take walks and relax around the canal in the Xinsheng South Road area. Since the completion of the restoration and development project, the canal network has drawn camera bugs to the Gongguan area. It’s common to see visitors arriving, relaxing, or waiting to snap an image or two of the Pallas squirrel or the Malayan night heron.

The waterway restoration plan was made in 2017 and the construction commenced in July 2020. After nearly a year of devoted effort, the restored area along Xinsheng South Road Section 3 was unveiled to the public in June 2021, signifying new life. The construction site extended from NTU’s Main Gate to the Sports Center. The old campus walls were torn down and replaced by eco-friendly shrubbery and the old bicycle and motorcycle parking lot was transformed into a hydrologic area with sidewalks flanked by greenery. The design was inspired by agricultural waterways seen in rural areas, creating a pleasant water landscape with humanistic and water detention features.


The hydrologic landscape project of Xinsheng South Road Section 3 executed by NTU and Taipei City Government demonstrates how an amenity-oriented environment can be built around canals.

Historically, Xinsheng South Road was called “Number One Special Route” in the 1932 Taipei City Planning Project during the Japanese colonial era. Later, a canal was dug beneath the road between 1938 and 1942. Known as Hori River, it served water detention and irrigation purposes. Beautiful willow trees lined the two sides of the canal, adding a touch of soft green to the area. Back then, the popular shaved-ice shop Taiyi Milk King was called the Haiyuen Dessert and Teashop(海源飲料總匯). The proprietor would place wooden planks out front so the students could cross the canal to savor their tea and desserts. From 1973, the canal was concealed beneath the cement road surface of Xinsheng South Road.

Now, water from the Xindian stream flows along the Liugongjun(瑠公圳) waterway and through the canals along Xinsheng South Road, forming a comprehensive hydrologic landscape across the campus. Moreover, the canal connects the green belt area outside NTU, creating a vibrant and idyllic space for people to appreciate the historical and ecological beauty of the area.

 


Twenty Years of Staying the Course—
NTU Swimming Team

Their arms stroking sharply and feet kicking fiercely against the water, the swimmers thrust through the water, forcefully but gracefully. They come within milliseconds of taking the gold medal. Coaches Chien-Ju Lin and Yi-Chung Chen stand at poolside in rapt attention with the team. Every eye is on the swimmers; they await the outcome with bated breath. The NTU swimmer in the center lane suddenly shoots ahead and hits the wall with a huge splash! When his hand strikes the wall, the team cheers in delight. Their jubilant spirit fills the air—the swimmer will bring home another gold medal! This is a moment that will be savored for years to come.

Continuing its thirty-year reign of dominance over collegiate swimming in Taiwan since 1982, the NTU Swimming Team has made a clean sweep of over 20 gold medals in competitions over the past two years. Swimmers in the General group are continuing a winning streak in both individual and relay events, having seized the honor of Team Champions several times over. Hailed as King of the Breaststroke in the General Group, Yu-Ping Huang drew his participation in ten Intercollegiate Athletic Games to a perfect close by winning 9 consecutive championships in the 100-m and 8 consecutive championships in the 200-m breaststroke. Players in the Professional group also stole the spotlight in competition at home and abroad. Mei-Chien Huang, the only Taiwanese female competitor in the swimming events, competed in the Women’s 50-m freestyle at the 2020 Tokyo Olympics. And, Cheng-Chi Cho who is strong in open water competitions has his heart set on competing in the 2024 Paris Olympics.

It is not just glamor and glory. Every NTU swimmer must undergo rigorous training and daily practice so the Swimming Team will achieve ever better and more consistent performances. Outside the pool, the team bonds like an extended family, often hanging out and holding activities together. Nothing beats a pleasant gathering after a difficult day practice, and nothing beats having trusty comrades to share those moments of glory in the pool.

NTU Alumni Keep the Lights Blinking

NTU strives to incorporate sustainability practices into every aspect of campus life, for example by protecting such precious wildlife species as Collared Scops Owls, Malayan Night-herons, Crested Goshawks, Muller's Barbets, and Red-bellied Tree Squirrels. Using the donations raised at the “50th Alumni Reunion” in 2016, NTU Campus Planning Office initiated firefly conservation work on campus and cleared a space at the NTU Experimental Farm to construct a clean, friendly residence for Aquatica ficta.

On August 28, NTU hosted a “Firefly Conservation Project” activity. Recent graduates of NTU nursery school and their parents were invited to release snails into the waters at NTU Experimental Farm. Since the fireflies prefer to dwell in humid areas near standing water and feed on small animals such as snails, the release of snails would provide sustenance for the larva until they pupate and become adults. It is hoped that these actions will help the campus be lit up by fireflies on summer evenings.

“In recent decades, NTU Experimental Farm has made efforts to create an organic environment. We’ve seen a few fireflies in the past, but we want to increase their population and improve our overall ecosystem. With the help of Adjunct Professor Ping-Shih Yang and the generous donations of our alumni, we will create ideal habitat conditions so that humanity can live in harmony with nature and promote environmental education,” asserted Distinguished Professor Huu-Sheng Lur, Dean of the College of Bioresources and Agriculture.

NTU Vice President for Financial Affairs Pei-Cheng Liao especially thanked Yu Wang, a former Dean of the College of Science, for assembling the alumni graduating in 1966 and for encouraging the class to support the cause.

Currently, there are over 300 thousand NTU alumni around the world. Every year they participate in NTU alumni activities and gatherings. Many members graduating in 1996 have immigrated to the United States, yet some of them returned to Taiwan to take part in the “50th Alumni Reunion” and demonstrate their love for their alma mater. In future years, it won't just be the memories that bring them back, but the magical lights of myriad fireflies on campus.
