Dynamometric Investigation on Airborne Particulate Matter from Automobile Brake: Impact of Disc Materials on Brake Emission Factor
Autor: Mu Hyeok Jeong, Won Cheol Shin, Yoon-Suk Oh, Jungju Lee, Seung Hun Huh, Jae-Hwan Pee, Hyungjo Seo, Ho Jang, Jong-Young Kim
Publikováno v: Lubricants, Vol 11, Iss 12, p 526 (2023)
In this work, we evaluated the impact of disc rotors of gray cast iron (GCI), nitrocarburized (NC), and superhard ceramic-coated (SCC) GCI on the brake wear PM emissions of passenger vehicles using dynamometric measurements. The brake emission factor

Dynamometric Investigation on Airborne Particulate Matter (PM) from Friction Materials for Automobile: Impact of Abrasive and Lubricant on PM Emission Factor
Autor: Sung-Hun Kim, Mu Hyeok Jeong, Jaegyeom Kim, Wooyoung Shim, Sung-Uk Kwon, Jung-Ju Lee, Seung Hun Huh, Jae-Hwan Pee, Jong-Young Kim
Publikováno v: Lubricants, Vol 9, Iss 12, p 118 (2021)
Reduction of non-exhaust airborne particulate matter (PM), leading to adverse effects in respiratory system, is an urgent task. In this work, we evaluated the impact of raw materials in friction materials on PM emission due to brake wear for passenge

Bulk Metamaterials Exhibiting Chemically Tunable Hyperbolic Responses
Autor: Myeongjeong Lee, In Chung, Hyungseok Lee, Sunae So, Junsuk Rho, Sung-Pyo Cho, Hyunsung Park, Jae-Hwan Pee, Eunsil Lee, Jaeseok Son, Bumki Min, Tae Won Noh, Bangzhi Ge, Wooyoung Shim, Jong-Young Kim, Zhongqi Shi, Sejin Byun
Publikováno v: Journal of the American Chemical Society. 143:20725-20734
Extraordinary properties of traditional hyperbolic metamaterials, not found in nature, arise from their man-made subwavelength structures causing unique light-matter interactions. However, their preparation requiring nanofabrication processes is high

Enhanced High-Temperature Electrical Resistivity of Aluminum Nitride Obtained by Engineering a Schottky Barrier at Grain Boundaries
Autor: Sung-Min Lee, Wooyoung Shim, Jong-Young Kim, Eunsil Lee, Jae-Hwan Pee
Publikováno v: Journal of the Korean Physical Society. 77:673-679
An enhanced high-temperature electrical resistivity of AlN at high voltage was obtained by using MgO doping to modulate the Schottky barrier. Doped MgO was precipitated in an ∼100-nm-thick layer near grain boundaries, which reduced not only anionic

Effect of alkali metal deintercalation on superconductivity in the KxFe2–ySe2 system
Autor: Jong-Young Kim, Sung-Hun Kim, Wooyoung Shim
Publikováno v: Journal of the Korean Ceramic Society. 57:658-668
In this work, the intercalation and subsequent deintercalation of alkali metal (K) were performed on new tetragonal β-FeSe compounds, and the effect on their superconductivity was studied. The FeSe precursor was intercalated with potassium by solid-
