Joint Online Conference by NTNU and the University of Glasgow on Climate Change Initiatives

On October 1, 2021, National Taiwan Normal University (NTNU) and the University of Glasgow (UOG) hosted an international conference online, inviting faculty from both institutions to deeply consider environmental education for sustainability. Specifically, the two universities discussed practical actions being implemented in Taiwan and the UK, related curriculum to be established in both schools, and measures for sharing research findings between NTNU and UOG to increase academic collaboration opportunities.

Taiwan's men's recurve bow archery team Bagged Bronze at the 2021 World Archery Championships

The 2021 World Archery Championships took place at Yankton in South Dakota. Taiwan's men's recurve bow archery team is mainly made up of NTNU alumni and students, including Coach Lee Tao Ming, Athelte Wei Chun Heng, Hung Cheng Hao are all from the Department of Athletic Performance. Wei just received silver medal from the 2020 Olympics and is now studying PhD in NTNU. He is the first NTNU trained athlete to receive a silver medal at the Olympics. Now, with Yu Guan Lin and Hung Cheng Hao and teammates, Taiwan’s men’s recurve team bagged bronze at 2021 World Archery Championships on September 25th.

Fruitful Discussion at the 25th Global Chinese Conference on Computers in Education

The 25th Global Chinese Conference on Computers in Education (GCCCE 2021) organized by The Education University of Hong Kong, Beijing Normal University, Taiwan Normal University and National Institute of Education, Nanyang Technological University in blended mode on 11 - 15 September 2021.

Association of hearing loss with dementia

In this study, HL was positively associated with dementia occurrence, especially in patients aged 45-64 years. Therefore, early hearing care, screening, and hearing aid use could be strategies to reduce dementia incidence.

Transformers in The Porous Materials Field: Extremely Fast Lattice Rearrangement of the MOF Structures

In this work, we present a case system that can achieve rapid structural rearrangement of the whole lattice of a metal–organic framework (MOF) through a ‘domino’ alteration of the bond connectivity under mild conditions. Topological transitions between significantly different phases typically require extreme conditions to collectively break chemical bonds and overcome the stress caused to the original structure by altering its correlated bond environment. Our system transforms from a disordered and less crystalline MOF with low porosity to a highly crystalline and porous isomer within few minutes upon activation (solvent exchange and desorption), resulting in a significant increase in surface area, from 725 to 2,749 m2/g. Spectroscopic measurements show that this counter-intuitive lattice rearrangement involves a metastable intermediate with defect frameworks that results from solvent removal on coordinately unsaturated metal sites. This less crystalline–crystalline switch between two topological distinct MOFs is shown to be reversible over four cycles through activation and re-immersion in polar solvents. The aim of this study was to investigate the partial defects in real MOF crystalline structures and to focus on defect-induced MOF properties, which are expected to enhance and develop the physical, mechanical, electronic and optical material properties and chemical activities of MOF materials. This research adopted an exploratory experimental procedure that facilitated the synthesis of highly porous MOFs, which were previously not easy to synthesize, and functional applications for defective and highly porous MOFs were further developed.
