Confined cavity on a mass-producible wrinkle film promotes selective CO2 reduction

Autor: Donggyu Kim, Issam Gereige, Seunghwa Ryu, Ju Ye Kim, Kyeong Min Cho, Geun-Tae Yun, Woo-Bin Jung, Yesol Kim, Hannes Jung, Ahmed Al-Saggaf

Publikováno v: Journal of Materials Chemistry A. 8:14592-14599

Reduction of CO2 to carbon monoxide (CO) is the starting point for producing valuable carbon chemicals and liquid fuels. To date, efficient CO2 electroreduction to CO has been accomplished predominantly by using the control of the structural paramete

Facile Fabrication of High-Definition Hierarchical Wrinkle Structures for Investigating the Geometry-Sensitive Fate Commitment of Human Neural Stem Cells

Autor: Soo-Yeon Cho, Sung Gap Im, Jieung Baek, Geun-Tae Yun, Woo-Bin Jung, Eunjung Lee, Younghak Cho, Hannes Jung

Publikováno v: ACS applied materialsinterfaces. 11(19)

As neural stem cells (NSCs) interact with biophysical cues from their niche during development, it is important to understand the biomolecular mechanism of how the NSCs process these biophysical cues to regulate their behaviors. In particular, anisot

Relationship between Hydrogen Evolution and Wettability for Multiscale Hierarchical Wrinkles

Autor: Hannes Jung, Geun-Tae Yun, Woo-Bin Jung, Yesol Kim, Minki Kim

Publikováno v: ACS applied materialsinterfaces. 11(7)

Transition metal dichalcogenides (TMDs) are emerging two-dimensional materials with potential use for the hydrogen evolution reaction (HER) because they express a desired binding energy with protons. To date, TMD-based HER catalytic performance has b
