HIU Seminar | Assist. Prof. Siraprapha Deebansok
Assist. Prof. Siraprapha Deebansok from the Tohoku University will be guest during the upcoming HIU Seminar taking place on Friday, 29th May 2026 at 2:00 pm: The talk will be held in person in the large seminar room (230) at the HIU and streamed under the usual Zoom link: The title of the talk will be "Multiscale analysis of electrochemical interfaces in energy materials: In-situ imaging and the most lightweight AI-assisted tool”.
Abstract
Electrochemical interfaces are key components for energy storage but are inherently heterogeneous across scales from the bulk to the nanoscale. We previously used in-situ optical imaging to observe solid–electrolyte interphase formation in water-in-salt electrolyte system, gaining real-time microscopic insights. Recently, we extended this approach to the nanoscale with in-situ electrochemical atomic force microscopy (EC-AFM) to examine electrode surface topology and mechanics during charge storage. Our focus is on MXene, a key 2D energy storage material valued for its high electrical conductivity, layered structure, and tunable surface chemistry.
In the first part, I will share our recent progress using EC-AFM to image MXene local structural features and surface evolution under electrochemical conditions, revealing degradation mechanisms in real-time.
In the second part, I will introduce our concept of integrating Deep Learning (DL) with material characterization using image data such as SEM images, creating an automated microscopy framework for high-throughput, quantitative analysis of particle morphology, composition, and impurities. We strongly aim to provide the lightest model so that any users without GPUs can easily use this AI workflow in their daily research.
By combining in-situ imaging and AI-based image analysis, this framework will open the door to a multiscale, quantitative approach relevant to functional materials in a wide range of applications.
