Effect of storage and curing conditions at elevated temperatures on aerogel-incorporated mortar samples based on UHPC recipe
Ng, Serina; Jelle, Bjørn Petter; Zhen, Yingpeng; Wallevik, Olafur Haralds (Journal article; Peer reviewed, 2016)The effect of elevated temperature during storage and curing of ultra-high performance concrete (UHPC) formulated aerogel-incorporated mortar (AIM) samples was investigated. It was found that an effective aerogel loading ... -
Electrochromic Properties of WO3 Thin Films: The Role of Film Thickness
Zhen, Yingpeng; Jelle, Bjørn Petter; Gao, Tao (Journal article, 2020)Tungsten oxide (WO3) thin films with various thicknesses of approximately 36, 72, 108, and 180 nm were prepared using radio frequency sputtering method. Film thickness can be controlled at nanoscale. In addition, X‐ray ... -

Zhen, Yingpeng (Doctoral theses at NTNU;2022:62, Doctoral thesis, 2022)The main objective of this thesis is to investigate electrochromic nanofilms and ionic liquid ion conductors (electrolyte) to make electrochromic devices for electrochromic smart window development. Electrochromic film and ... -
Measurements of ionic liquids thermal conductivity and thermal diffusivity
Zhao, Yansong; Zhen, Yingpeng; Jelle, Bjørn Petter; Boström, Tobias (Journal article; Peer reviewed, 2017)Thermal conductivity and thermal diffusivity of ionic liquids (ILs) are investigated in this work. A hot disk method for ILs thermal conductivity and thermal diffusivity measurement is utilized. Firstly, the thermal ... -
Rechargeable Iron-Ion Battery Using a Pure Ionic Liquid Electrolyte
Zhao, Yansong; Zhen, Yingpeng; Boström, Tobias Kristoffer (Peer reviewed; Journal article, 2022)A rechargeable iron-ion battery (Fe-ion battery) has been fabricated in our laboratory using a pure ionic liquid electrolyte. Magnetic ionic liquids of 1-butyl-3-methylimidazolium tetrachloroferrate (BmimFeCl4) and ... -
Synthesis and Characterization of Tungsten Oxide Electrochromic Thin Films
Zhen, Yingpeng; Gao, Tao; Jelle, Bjørn Petter (Chapter, 2018)A radio frequency sputtering method was utilized and developed for tungsten oxide film preparation. The thickness of tungsten oxide film can be controlled at nano scale. Tungsten oxide thin films with thickness of ~36 nm ...
