In situ atomistic insight into the growth mechanisms of single layer 2D transition metal carbides
Xiahan Sang,Yu Xie,Dundar E. Yilmaz,Roghayyeh Lotfi,Mohamed Alhabeb,Alireza Ostadhossein,Babak Anasori,Weiwei Sun,Xufan Li,Kai Xiao,Paul R. C. Kent,Adri C. T. van Duin,Yury Gogotsi,Raymond R. Unocic +13 more
TL;DR: In situ aberration-corrected scanning transmission electron microscopy is used to reveal the homoepitaxial growth mechanisms of a single TiC adlayer from a Ti3C2 monolayer substrate, which could lead to the development of bottom-up synthesis methods using substrates terminated with similar hexagonal-metal surfaces.
Tracking ion intercalation into layered Ti3C2 MXene films across length scales
Qiang Gao,Weiwei Sun,Weiwei Sun,Poorandokht Ilani-Kashkouli,Alexander Tselev,Paul R. C. Kent,Nadine Kabengi,Michael Naguib,Mohamed Alhabeb,Wan-Yu Tsai,Arthur P. Baddorf,Jingsong Huang,Stephen Jesse,Yury Gogotsi,Nina Balke +14 more
TL;DR: In this article, the authors report a highly integrated study with multiscale theory/modelling and experiments to track the intercalation of aqueous Li+, Na+, K+, Cs+, and Mg2+ ions into Ti3C2 MXene.

Double transition metal MXenes with wide band gaps and novel magnetic properties
TL;DR: This work studies MXenes with a central Ti layer and different surface early 3d metals, and various terminations, and predicts surface metal and termination dependent metal-insulator transitions in the Cr-N and Mn-N series.

Effects of Surface Terminations of 2D Bi2WO6 on Photocatalytic Hydrogen Evolution from Water Splitting.
Sujuan Wu,Sujuan Wu,Jianguo Sun,Jianguo Sun,Qi Li,Zachary D. Hood,Zachary D. Hood,Shize Yang,Tongming Su,Tongming Su,Rui Peng,Zili Wu,Weiwei Sun,Paul R. C. Kent,Bin Jiang,Matthew F. Chisholm +15 more
TL;DR: This work highlights an effective way to design photocatalysts with efficient hydrogen generation from water splitting by tuning the surface terminations by exploiting the thermodynamic driving potential for efficient electron injection.
