Park, Ji Won (author), Kim, S. (author), Noh, Jin Hyung (author), Bae, Young Ho (author), Lee, Jae Woo (author), Maeng, Sung Kyu (author)From 2022, industrial wastewater discharge regulations in South Korea will replace chemical oxygen demand (COD<sub>Mn</sub>) with total organic carbon (TOC). A shift from COD<sub>Mn</sub> to TOC is a pioneering change in protecting water bodies from organic contaminants. However, several industries are struggling to meet these TOC...journal article 2022

(author), Kim, Youngsok (author), Lee, Jinho (author)Sequence alignment forms an important backbone in many sequencing applications. A commonly used strategy for sequence alignment is an approximate string matching with a two-dimensional dynamic programming approach. Although some prior work has been conducted on GPU acceleration of a sequence alignment, we identify several shortcomings that limit...conference paper 2022

Kim, Jinhyun (author), Um, Yunna (author), Han, Seunghyun (author), Hilberath, T. (author), Kim, Yong Hwan (author), Hollmann, F. (author), Park, Chan Beum (author)The pulp and paper manufacturers generate approximately 50 million metric tons of lignin per annum, most of which has been abandoned or incinerated because of lignin's recalcitrant nature. Here, we report bias-free photoelectrochemical (PEC) oxidation of lignin coupled with asymmetric hydrogenation of C=C bonds. The PEC platform consists of a...journal article 2022
