Conceptual Design and Demonstration of Space Scale for Measuring Mass in Microgravity Environment
Autor: Youn-Kyu Kim, Joo-Hee Lee, Gi-Hyuk Choi, Ik-Hyeon Choi
Publikováno v: Journal of Astronomy and Space Sciences, Vol 32, Iss 4, Pp 419-425 (2015)
In this study, a new idea for developing a space scale for measuring mass in a microgravity environment was proposed by using the inertial force properties of an object to measure its mass. The space scale detected the momentum change of the specim

To obtain soft electronics, it is essential to develop high-performance and mechanically flexible energy storage at the industry level. Herein, we report flexible high-energy-density lithium-sulfur (Li–S) batteries based on all-fibrous sulfur catho

Finite element analysis of low-velocity impact response of convex and concave composite laminated shells
Autor: Ik Hyeon Choi
Publikováno v: Composite Structures. 186:210-220
The transient response of composite laminated cylindrical shells with convex and concave shapes, subjected to low-velocity impact, was numerically investigated. Geometrically linear analysis without consideration of the membrane effect demonstrated t

A Novel Strategy to Overcome the Hurdle for Commercial All‐Solid‐State Batteries via Low‐Cost Synthesis of Sulfide Solid Electrolytes
Autor: Seong Chan Jo, Yoon-Cheol Ha, Byung Gon Kim, Sang-Min Lee, Sung Kang, Min-Ju Kim, Ik-Hyeon Choi, Kang-Jun Baeg, Jun-Woo Park
Publikováno v: Small Methods. 5:2100793
Unlike commercial lithium-ion batteries, the high cost and low ionic conductivity of solid electrolytes (SEs) continues to be a big hurdle in commercially available all-solid-state batteries (ASSBs). Rather than the conventional dry-process and high-

Low-velocity impact response analysis of composite pressure vessel considering stiffness change due to cylinder stress
Autor: Ik Hyeon Choi
Publikováno v: Composite Structures. 160:491-502
To accurately analyse the transient response and damage of pressurized vessels subjected to a drop impact or foreign object impact, we must consider the change in stiffness due to pre-stress. The pre-stress condition induces a phenomenon where thin p
