When a water drop is impinged upon superhydrophobic surfaces, various interesting physical phenomena can occur depending on physical structures on the surfaces. In this talk, I will focus on two phenomena during drop impact: the contact time between the drop and the surface and the...
A new high-order projection method for simulating incompressible turbulent flows is presented based on weighted essentially non-oscillatory (WENO) schemes. By the combination of successively higher orders of WENO and CD schemes, the desired order of accuracy (up to seventh order) was achieved without appreciable extra...
Title Optical structure engineering of thin films for photonic applications Abstract Flow of light waves propagating inside an optical medium is affected by the light-induced polarizability and interfacial dipolar response of materials. In addition, since the light is electromagnetic waves of which governing equations are generally reducible to...
Design and exploration of advanced materials for lithium-ion batteries and beyond Kisuk KANG Professor College of Engineering, Seoul National University, Korea Abstract High-performance and cost-effective rechargeable batteries are key to the success of electric vehicles and large-scale energy storage systems. Extensive research has thus focused on the development of new high-energy electrodes that can store more lithium at faster rates with stable cycle performance. However, the current status of lithium batteries still remains far below the demands required for the proposed applications. In this presentation, I introduce our approaches to address this issue, which include the discovery of new energy storage mechanism in the electrode for lithium ion batteries, bio-mimetic batteries and some developments made in the field of post lithium ion batteries in our group....
