You are cordially invited to attend the Lecture of Sustainability and Energy Technologies. We are pleased to have Professor Tetsu Yonezawa, Division of Materials Science and Engineering, Hokkaido University as our speaker. The topic of the lecture is " Preparation and Dispersion of Cu Nanoparticles for Semiconductor Packaging ". Further details are as follows: 1.Topic: Preparation and Dispersion of Cu Nanoparticles for Semiconductor Packaging 2.Speaker: Professor Tetsu Yonezawa 3.Abstract: Copper nanoparticles are promising for next-gen interconnects due to high conductivity and low-cost processing. However, oxidation under ambient conditions limits their performance. We present oxidation-tolerant core–shell Cu nanoparticles with Cu64O/Cu8O-rich surfaces, enabling thermal stability and sinterability. Using sugar alcohol-based solvents, we formulate >80 wt% copper pastes with excellent dispersion and film-forming properties. Thermal analysis, in situ XRD, and sintering studies show strong bonding and conductivity below 200°C under reducing/inert atmospheres. This approach suits 3D integration, power devices, and flexible electronics, offering a practical route for copper nanoparticle use in semiconductor packaging with enhanced reliability and low-temperature processing. 4.

You are cordially invited to attend the Lecture of Sustainability and Energy Technologies. We are pleased to have Professor Chih-Wei Hu from Institut de Chimie de la Matière Condensée de Bordeaux (ICMCB-CNRS) as our speaker. The topic of the lecture is " A Scientific Adventure Across Borders: The Journey of Developing Hydrogen Sensing Materials ". Further details are as follows: 1.Topic: A Scientific Adventure Across Borders: The Journey of Developing Hydrogen Sensing Materials 2.Speaker: Professor Chih-Wei Hu 3.Abstract: Professor Chih-Wei Hu will share his more than decade-long scientific journey spanning Taiwan, Japan, and France, with a focus on the innovative development of hydrogen sensing materials. As an emerging clean energy carrier, hydrogen offers high energy density and eco-friendly properties. However, its use and storage pose potential safety risks, making the development of high-performance hydrogen sensing materials a central issue in global materials science. After receiving his Ph.D. in Polymer Science from National Taiwan University, Professor Hu spent ten years at Japan’s National Institute of Advanced Industrial Science and Technology (AIST), where he specialized in nanomaterials and gasochromic sensing technologies, actively collaborating with academia, industry, and government sectors in Japan and Taiwan to promote material commercialization. More recently, he joined the French National Centre for Scientific Research (CNRS) to explore new mechanisms in sensing materials, reflecting a strong commitment to international exchange and interdisciplinary collaboration. His talk will cover the full spectrum from fundamental material design and nanostructure synthesis to hydrogen visualization sensing solutions under extreme environments. Drawing on his multinational research experiences, he will highlight how materials science can drive energy safety and contribute to a sustainable future. 4.Date: 2025/10/14 (Tue) 10:30~12:00 5.

You are cordially invited to attend the Lecture of Sustainability and Energy Technologies. We are pleased to have Distinguished Professor Fu-Ming Wang from Graduate Institute of Applied Science and Technology at National Taiwan University of Science and Technology as our speaker. The topic of the lecture is " Investigations of organic coverage (OC) design on lithium-ion battery and the beyond ". Further details are as follows: 1.Topic: Investigations of organic coverage (OC) design on lithium-ion battery and the beyond 2.Speaker: Distinguished Professor Fu-Ming Wang 3.Abstract: The performance of lithium batteries is critically dependent on efficient ionic conduction within the electrolyte and electronic conduction in the electrode materials. Advancing high-performance electric vehicles and next-generation energy storage systems requires achieving high energy density without compromising the intrinsic properties of both electrolytes and electrodes. Furthermore, lithium battery recycling and the development of alternative energy storage technologies are central to the circular economy strategies of many countries and represent a strategic focus for the post-lithium battery era. 4.Date: 2025/05/29 (Thu.) 10:30~12:00 5.Venue: 1st Meeting Room of Engineering College (Engineering Building 1F) 6.Registration Deadline: 2025/5/28(Wed) Campus Information System iCGU URL: https://i.cgu.edu.tw Important Notes: This lecture qualifies for 1.5 hours of training for the teaching quality seminar.

To address the high energy consumption and carbon emissions of the traditional Haber-Bosch process, the team developed a Joule heating method to rapidly synthesize homogeneous copper-based bimetallic catalysts (CuNi, CuFe, CuPd). This ultra-fast method—completed in just seconds—uses high-temperature decomposition and rapid quenching to form nano-alloy catalysts with uniform dispersion and small particle sizes. Among the catalysts, CuNi exhibited the best performance, achieving an ammonium selectivity of 98% and a yield of 49%, outperforming monometallic Cu catalysts significantly in the electrochemical reduction of nitrate (NO₃⁻) to #ammonium (NH₄⁺). More importantly, this approach not only tackles nitrate-polluted wastewater but also transforms pollutants into valuable resources—an ideal embodiment of the Circular Economy: turning waste into wealth with high efficiency and sustainability.
