Accelerated Material Design Framework using Uncertainty-Quantified Hybrid Machine Learning/Density Functional Theory Approach
Prof. Yousung Jung’s group has developed a new accelerated high throughput screening (HTS) method using uncertainty-quantified machine learning (ML) and density functional theory (DFT) that was applied to explore the Mg-Mn-O chemical space for photoanode application. Notably, the proposed HTS scheme required only 1.5% of the target chemical space for further DFT calculations, accelerating the entire process by > 50 times for the same discovery compared to the brute-force DFT-HTS done previously. This means an improvement of the screening performance (discoverability) by more than a factor of 2 compared to the conventional ML-based HTS approach....read more

Ultra-large and Multi-stimuli-responsive Smart Windows
Prof. Il-Doo Kim, Prof. Hong Jung-Wuk, and Prof. Seokwoo Jeon jointly developed a novel multi-stimuli-responsive (thermochromic and mechanochromic) membrane based on light scattering at strain-induced nanogaps from oxides and elastomers together with thermochromic dyes. The combination of the polymer writing technique with roll-to-roll production effectively expanded the production area of the smart window membrane to an exceptionally large scale of nearly 300 cm2, far beyond those of previously reported optical modulating membranes to date....read more

New Nanoparticle Drug Combination Treats and Prevents Atherosclerosis
Dr. Ji-Ho Park’s group developed a cargo-switching nanoparticle (CSNP) system that can bind to cholesterol and then release an anti-inflammatory drug (statin) in a plaque-containing microenvironment. The as-developed CSNP had a core-shell structure, with a core composed of cyclodextrin and statin and a shell of phospholipids. In vitro, once interacting with cholesterol, which had a higher affinity to cyclodextrin than statin, the CSNP can instantly release statin and scavenge cholesterol by cargo-switching. In vivo, in a mouse model of atherosclerosis, the CSNP administered systemically can effectively target atherosclerotic plaques and reduce their associated cholesterol and macrophages, leading to prevention of atherogenesis and regression of established plaques....read more
