Mie-tronics under microscopy

Since a millennium ago, it is well known that grinding metals yields various colors, presented as the beautiful colored windows in churches or the famous Lycurgus Cup. However, the underlying physics was not elucidated until Gustav Mie developed the corresponding electromagnetic wave scattering theory in the early 20th century. The Mie theory explains how structuring metals to sizes comparable to light wavelengths, not much smaller nor much larger, creates new optical resonances, enhancing absorption/scattering of specific wavelengths, and producing vivid colors. In the 21st century, the nanoscale Mie resonance phenomenon has been…

Anticipating the occurrence and type of critical transitions

Chun-Wei Chang and Chih-hao Hsieh Prof. Chih-hao Hsieh from the Institute of Oceanography and Prof. Chun-Wei Chang from the Institute of Fishery Sciences, NTU lead an international team and develop a novel method that successfully anticipates the occurrence and type of a variety of critical transition events. This study, published in Science Advances (Jan 2023), overcomes the long-lasting challenge in revealing a quantitative threshold as well as distinguishing types of critical transition by early warning signals using empirical data collected in real-world systems. The proposed method also provides a powerful…

Split westerly winds over Europe – A breakthrough by an international project led by Department of Geosciences

Europe, even located at the mid-high latitude at 40-70oN, the autumn and winter are mild and comfortable. Such pleasant weather is regulated by the warm and humid westerly winds from the North Atlantic Ocean. During the 15th to 19th century, Europe experienced the coldest winters over the last ten thousand years, known as the “Little Ice Age” (LIA). The LIA was suggested to be caused by volcanic eruptions and low solar activity. However, the detailed climate pattern in Europe remains unclear.Dr. Hsun-Ming Hu, the first author, and Prof. Chuan-Chou Shen,…

Exploring global pollution and cycling of mercury using ocean migratory fish

Profs. Chun-Mao Tseng and Jen-Chieh Shiao from the Institute of Oceanography, NTU, and the US cooperative colleagues worked together as the mercury research team (referred to Team Mercury (Hg) hereinafter). The research provides them to initiate a new tool of the mercury accumulation rate (MAR) using top predators to examine global patterns in the cycling and pollution of Hg across the world's oceans. It also confirms the unchanging truth of "You are what you eat, and You have what you are" since time began. The results of this study, published…

Professor Ching-Ray Chang and his collaborators publish “Yang–Mills physics in spintronics” paper in <Physics Reports>

The National Taiwan University has, in an international team effort, collaborated with the Chinese Culture University, the University of Taipei, the National University of Singapore, the Royal Melbourne Institute of Technology, and the Tokyo Institute of Technology, to write a review article on the physics of Yang-Mills in spintronics. This article was recently published in the Physics Reports (Oct 2020). Physics Reports has always been one of the academic journals with the highest impact factor in physics community. The 5-Year Impact Factor is 24.659, which is much higher than the…

Prominent studies by NTU Institute of Oceanography research team published in prestigious journal “Nature Communications” 2020.8.14

Life histories determine divergent population trends for fishes under climate warming Hui-Yu Wang, Sheng-Feng Shen, Ying-Shiuan Chen, Yun-Kae Kiang, and Mikko Heino Dr. Hui-Yu Wang (IO NTU), Dr. Sheng-Feng Shen (AS BRC), and Dr. Mikko Heino (UiB, Norway) have conducted the first assessment of warming-induced effects on various types marine fishes in the Indo-Pacific. Their findings reveal that warming impacts are not uniform; instead, warming impacts are contingent on life histories of fishes. Their study was published in Nature Communications on Aug 14, 2020. The research team investigated temperature effects…
