K2Ti6O13 Nanoparticle-Loaded Porous rGO Crumples for Supercapacitors

Autor: Chongmin Lee, Sun Kyung Kim, Hankwon Chang, Hee Dong Jang

Publikováno v: Nano-Micro Letters, Vol 12, Iss 1, Pp 1-9 (2019)

Abstract One-dimensional alkali metal titanates containing potassium, sodium, and lithium are of great concern owing to their high ion mobility and high specific surface area. When those titanates are combined with conductive materials such as graphe

Autor: Ji-Hyuk Choi, Hankwon Chang, Taegong Ryu, Chul-Woo Nam, Byung-Su Kim

Publikováno v: Metals, Vol 10, Iss 11, p 1493 (2020)

The aluminothermic process is used for producing ferrotitanium alloy (FeTi) from an ilmenite concentrate. In this study, based on thermodynamic calculations and experiments, we investigated the effects of adding varying amounts of exothermal agent (N

Aerosol Processing of Graphene and Its Application to Oil Absorbent and Glucose Biosensor

Autor: Sun Kyung Kim, Hankwon Chang, Jeong-Woo Choi, Jiaxing Huang, Hee Dong Jang

Publikováno v: KONA Powder and Particle Journal, Vol 31, Iss 0, Pp 111-125 (2014)

Graphene (GR) is a flat monolayer of sp2-bonded single carbon atoms densely packed into a honeycomb crystal lattice. Due to its unique characteristics, GR is expected to contribute to enhanced nanoelectronic, bio-electronic devices, etc. in the near
