Hall, Drew A. (author), Makinwa, K.A.A. (author), Jang, Taekwang (author)There has been a long-standing interest in controlling and instrumenting the human body. Whether to restore lost function with neural prosthetics, monitor blood glucose levels, or augment human capabilities, there are countless opportunities for sensors inside ( e.g., ingestible, injectable, and implantable) and outside ( e.g., wearable) the...journal article 2023

Okonkwo, Bright O. (author), Jeong, Chaewon (author), Lee, Hyeon Bae (author), Jang, Changheui (author), Rahimi, E. (author), Davoodi, Ali (author)In this study, we developed and optimized a trivalent chromium coating electrodeposited on 304L stainless steel (SS) from a Cr-trivalent bath. The results reveal that the Cr coatings at all bath temperatures except for 80 °C showed clusters of polyhedral grains, however, the grain sizes decreased with an increase in bath temperature. Also,...journal article 2023

(author), Baek, Ju Hyun (author), Do, Hyeon Seok (author), Choi, Yeon Taek (author), Gwon, Hojun (author), Suh, Jin Yoo (author), Kim, Hyoung Seop (author), Lee, Byeong Joo (author), Zargaran, Alireza (author), Sohn, Seok Su (author)Complex concentrated alloys (CCAs) with a face-centered-cubic (FCC) structure exhibit remarkable mechanical properties, introducing the expansion of compositional space in alloy design for structural materials. The formation of a single solid-solution phase is enabled by configuring various 3d-transition elements, while doping other elements...journal article 2023

Yoon, Jaeho (author), Jang, Hanhwi (author), Oh, Min Wook (author), Hilberath, T. (author), Hollmann, F. (author), Jung, Yeon Sik (author), Park, Chan Beum (author)Heat is a fundamental feedstock, where more than 80% of global energy comes from fossil-based heating process. However, it is mostly wasted due to a lack of proper techniques of utilizing the low-quality waste heat (<100 °C). Here we report thermoelectrobiocatalytic chemical conversion systems for heat-fueled, enzyme-catalyzed...journal article 2022

Sun, Bingrong (author), Gong, Lin (author), Shim, J. (author), Jang, Kitae (author), Park, B. Brian (author), Wang, Hongning (author), Hu, Jia (author)Real-world route navigation data indicate that nontrivial portion of drivers do not prefer the system-recommended best routes. Current navigation systems have simplified assumptions about drivers’ route choice preferences and do not adequately accommodate drivers’ heterogeneous route choice preferences, mainly because of: (i) difficulty in...journal article 2022

Hwang, Jiyoon (author), Krylov, Denis (author), Elbertse, R.J.G. (author), Yoon, Sangwon (author), Ahn, Taehong (author), Oh, Jeongmin (author), Fang, Lei (author), Jang, Won Jun (author), Cho, Franklin H. (author)Recent advances in improving the spectroscopic energy resolution in scanning tunneling microscopy (STM) have been achieved by integrating electron spin resonance (ESR) with STM. Here, we demonstrate the design and performance of a homebuilt STM capable of ESR at temperatures ranging from 1 to 10 K. The STM is incorporated with a homebuilt...journal article 2022

(author), Choi, Pyuck Pa (author), Sohn, Seok Su (author)Precipitation strengthening has been the basis of physical metallurgy since more than 100 years owing to its excellent strengthening effects. This approach generally employs coherent and nano-sized precipitates, as incoherent precipitates energetically become coarse due to their incompatibility with matrix and provide a negligible...journal article 2021

Choi, Woojun (author), Lee, Yongtae (author), Kim, Seonhong (author), Lee, Sanghoon (author), Jang, Jieun (author), Chun, Junhyun (author), Makinwa, K.A.A. (author), Chae, Youngcheol (author)This paper presents a compact resistor-based CMOS temperature sensor intended for dense thermal monitoring. It is based on an RC poly-phase filter (PPF), whose temperature-dependent phase shift is read out by a frequency-locked loop (FLL). The PPF's phase shift is determined by a zero-crossing (ZC) detector, allowing the rest of the FLL to be...journal article 2018

Jang, S.H. (author), Na, Seon Hong (author), Park, Yong Lae (author)This article presents a soft pneumatic bending actuator using a magnetically assisted bilayer composite composed of silicone polymer and ferromagnetic particles. Bilayer composites were fabricated by mixing ferromagnetic particles to a prepolymer state of silicone in a mold and asymmetrically distributed them by applying a strong non-uniform...journal article 2017
