TL;DR: In this paper, a hydrogen annealing method was used to increase the oxidation stability of Ti3C2 MXene in two different aspects: (1) dramatic improvement in the oxidation resilience of pristine MXene films against harsh conditions (100% relative humidity, 70 °C), and (2) large recovery in the electrical conductivity of previously oxidized Ti3c2 MXenes films.

Indentation size effect and shear transformation zone size in a bulk metallic glass in two different structural states
In-Chul Choi,Yakai Zhao,Yong-Jae Kim,Byung Gil Yoo,Jin-Yoo Suh,Upadrasta Ramamurty,Jae-il Jang +6 more
TL;DR: The existence of an indentation size effect (ISE) in the onset of yield in a Zr-based bulk metallic glass (BMG) was investigated by employing spherical-tip nanoindentation experiments.
Journal ArticleDOI
Estimation of the shear transformation zone size in a bulk metallic glass through statistical analysis of the first pop-in stresses during spherical nanoindentation
In-Chul Choi,Yakai Zhao,Byung-Gil Yoo,Yong-Jae Kim,Jin-Yoo Suh,Upadrasta Ramamurty,Jae-il Jang +6 more
TL;DR: The size of the shear transformation zone (STZ) that initiates the elastic to plastic transition in a Zr-based bulk metallic glass was estimated by conducting a statistical analysis of the first pop-in event during spherical nanoindentation as discussed by the authors.
Journal ArticleDOI
Increased time-dependent room temperature plasticity in metallic glass nanopillars and its size-dependency
Byung-Gil Yoo,Ju-Young Kim,Yong-Jae Kim,In-Chul Choi,Sanghoon Shim,Ting Y. Tsui,Hongbin Bei,Upadrasta Ramamurty,Jae-il Jang +8 more
TL;DR: In this paper, the authors investigated the influence of sample size on the time-dependent plastic deformation behavior in amorphous alloys and found that at a given stress, higher total strains accrue in the smaller specimens.
