Electrostatic control of Li+ density and transport rate in double-gated van der Waals devices
E. Hoenig, X. Zhang, C. Li +7
Ion transport in crystalline hosts is controlled by an applied potential that simultaneously sets ionic distribution and transport rate, restricting operation to a one-dimensional…
Layer-selective hydrogenation and proton transport in twisted bilayer graphene
J. Tong, G. Chen, H. Li +13
Recent work investigated graphene's hydrogenation with independent control of the electric field, E, and charge density, n, in the crystal and showed that the process is controlled…
Tuneable ion selectivity in vermiculite membranes intercalated with unexchangeable ions
Zhuang Liu, Yumei Tan, Jianhao Qian +8
Membranes selective to ions of the same charge are increasingly sought for wastewater processing and valuable element recovery. However, while narrow channels are known to be essen…
Mechanism of the electrochemical hydrogenation of graphene
Y. -C. Soong, H. Li, Y. Fu +17
The electrochemical hydrogenation of graphene induces a robust and reversible conductor-insulator transition, of strong interest in logic-and-memory applications. However, its mech…
High proton conductivity through angstrom-porous titania
Y. Ji, G. -P. Hao, Y. -T. Tan +10
Two dimensional (2D) crystals have attracted strong interest as a new class of proton conducting materials that can block atoms, molecules and ions while allowing proton transport…
