Modulation engineering of in-situ cathodic activation of FePx based on W-incorporation for hydrogen evolution

Nanoscale, 2020, Accepted Manuscript
DOI: 10.1039/D0NR02661A, Paper
Min Yang, Yu-Ran Zhu, Zhong-Yuan Lin, Xin-Tong Yan, Bin Dong, Ya-Nan Zhou, Qingzhong Li, Yulu Zhou, Jun Nan, Yongming Chai
In-situ electrochemical activation as a new pretreating method to adjust electrocatalytic performance attracts extensive attention. However, the activation mechanisms of electrocatalysts are still ambiguous. Herein, we propose a facile modulation...

Topological semimetal Li2CrN2 sheet as a promising hydrogen storage material

Nanoscale, 2020, Accepted Manuscript
DOI: 10.1039/D0NR02180F, Paper
Lijuan Ma, Qiang Sun
An ideal electrode for electrochemical storage of hydrogen needs to be conductive for electron. The robust conductivity protected by topology in topological quantum materials just meets this requirement. However, such...

Gender Theory in Troubled Times


 
Theorizing gender is more urgent and highly political than ever before. These are times, in many countries, of increased visibility of women in public life and high-profile campaigns against sexual violence and harassment. Challenges to fixed, traditional gender norms have paved the way for the recognition of gay marriage and gender recognition acts allowing people to change the gender assigned to them at birth. Yet these are also times of religious
