A Cu2B2 monolayer with planar hypercoordinate motifs: an efficient catalyst for CO electroreduction to ethanol

J. Mater. Chem. A, 2020, Advance Article
DOI: 10.1039/D0TA02471F, Paper
Jingjing Jia, Haijun Zhang, Zhongxu Wang, Jingxiang Zhao, Zhen Zhou
By means of first-principles computations, we identified that metallic Cu2B2 monolayer with planar heptacoordinate motifs could effectively reduce CO to ethanol through the “carbene” mechanism with a low limiting potential and a small barrier for C–C coupling.

Semiconducting polymer contributes favorably to the Seebeck coefficient in multi-component, high-performance n-type thermoelectric nanocomposites

J. Mater. Chem. A, 2020, Advance Article
DOI: 10.1039/D0TA02388D, Paper
Junhui Tang, Ruisi Chen, Lidong Chen, Guillermo C. Bazan, Ziqi Liang
n-Type Co NWs/N2200 TENCs yield a high S, mainly from the semiconducting polymer, yet σ is limited by poor connectivity between inorganic and organic domains. By adding flexible n-doped SWCNTs to yield more conductive paths, σ and mechanical bendability are greatly enhanced.

WATCH LIVE - Opening Celebration of “Rosa Parks: In Her Own Words”

Starting at 7 p.m EST., tonight Dec. 4, 2019. 

A new Library of Congress exhibition,“Rosa Parks: In Her Own Words,” opens December 5. Celebrate Rosa Parks with us at this opening event. Hear from Librarian of Congress Carla Hayden, the Honorable John Lewis & others.

WELCOME: Carla Hayden, Librarian of Congress

REMARKS: The Honorable John Lewis, Representative from Georgia

DISCUSSION: Fred Gray and Jane Gunter, Moderated by Michelle Miller, CBS News The exhibition will immerse visitors in Parks’ words, reflections, handwritten notes and photographs, allowing her to tell her own life story. It is the first exhibition of Rosa Parks’ personal collection.

The exhibition offers an intimate view of this seminal figure’s life – beyond her famous refusal to give up her seat to a white man on a city bus – to reveal the real Rosa Parks, a seasoned activist with a spirit forged over decades of challenging inequality and injustice.
