Issue No. 168Time: 10:00 a.m. April 24Location: B-515 Lee Shau Kee Building of Science and TechnologyHost: Prof. Xuefei XUAbstract:Owing to the impressive growth of computational power and of the development of novel computational techniques, including data-driven approaches, nowadays it is possible to simulate the behavior of matter under disparate conditions with unprecedented reliability. In.…

Issue No. 167Time: 10:00-11:30 a.m. April 15Location: B-518 Lee Shau Kee Building of Science and TechnologyHost: Prof. Chao SunAbstract:The freezing of water within porous media entails a variety of dynamics in which micro-and macro-scale phenomena blend. Among many, soil expansion, produced by ice segregation and underground water drawn therein by the freezing process itself, is one of the mos.…

Issue No. 166Time: March 25, 19:20Location: B-518 Lee Shau Kee Building of Science and TechnologyHost: Prof. Yixiang Shi and Prof. Ran SuiAbstract:The talk focuses on alternative electro- and thermo-catalytic pathways for the production and decomposition of ammonia related to its use as carrier of renewable energy. Recent advances in electrocatalytic ammonia synthesis in proton-conducting ceram.…

Issue No. 165时间: 2026年1月7日(周三)下午15:00地点: 李兆基科技大楼会议室B518邀请人: 张亮 副教授Abstract:以清洁电能为驱动的CO₂还原反应（CO₂RR）是实现“双碳”目标的潜在技术。随着气体扩散电极（GDE）的应用，CO₂RR反应速率已接近工业化水平。然而，受限于对GDE中反应物传输机制、催化剂表面微环境及高活性位点分布的认识不足，高效电极结构与反应器件仍需优化。本文研究发现，在釜式电解池中，CO₂主要通过GDE背面.…

Issue No. 164Time: 14:00-15:15 p.m. December 25Location: B-515 Lee Shau Kee Building of Science and TechnologyHost: Prof. Chao SunAbstract:Convection in rapidly rotating fluids and mixing through porous media are often treated as distinct problems: one is constrained by Coriolis forces and Ekman layers, the other by Darcy drag and permeability. Yet both systems share a unifying feature: momentu.…

Issue No. 163Time: 15:00 p.m. on November 11, 2025Location: B-518 Lee Shau Kee Building of Science and TechnologyHost: Prof. Chao SunAbstract:We show how to apply optimal control theory to catch a passive drifting target in a turbulent flow by an autonomous flowing agent with limited maneuverability. For the case of a perfect knowledge of the environment, we show that Optimal Control theory can.…

Issue No. 162Time: 14:00 p.m. on November 11, 2025Location: B-518 Lee Shau Kee Building of Science and TechnologyHost: Prof. Chao SunAbstract:Lagrangian turbulence lies at the core of numerous applied and fundamental problems. However, despite decades of theoretical, numerical, and experimental research, no existing model can accurately reproduce particle trajectories’ statistical and topologi.…

Issue No. 161Time: 9:30 a.m. on November 11, 2025Location: B-518 Lee Shau Kee Building of Science and TechnologyHost: Prof. Chao SunAbstract:In physics, noise is usually associated with small, fast perturbations to the system under study — something we want to eliminate. However, in complex systems such as turbulent flows and climate dynamics, noise should be considered the result of different.…
