Journal ArticleDOI
Synthesis of MoS2 and MoSe2 Films with Vertically Aligned Layers
TL;DR: This communication presents a synthesis process to grow MoS2 and MoSe2 thin films with vertically aligned layers, thereby maximally exposing the edges on the film surface, and confirmed their catalytic activity in a hydrogen evolution reaction (HER), in which the exchange current density correlates directly with the density of the exposed edge sites.
Journal ArticleDOI
Sulphur–TiO2 yolk–shell nanoarchitecture with internal void space for long-cycle lithium–sulphur batteries
Zhi Wei Seh,Weiyang Li,Judy J. Cha,Guangyuan Zheng,Yuan Yang,Matthew T. McDowell,Po-Chun Hsu,Yi Cui,Yi Cui +8 more
TL;DR: This work demonstrates the design of a sulphur-TiO(2) yolk-shell nanoarchitecture with internal void space to accommodate the volume expansion of sulphur, resulting in an intact TiO( 2) shell to minimize polysulphide dissolution.
Journal ArticleDOI
Hollow Carbon Nanofiber-Encapsulated Sulfur Cathodes for High Specific Capacity Rechargeable Lithium Batteries
TL;DR: The results show that the hollow carbon nanofiber-encapsulated sulfur structure could be a promising cathode design for rechargeable Li/S batteries with high specific energy.
Journal ArticleDOI
Self-limited plasmonic welding of silver nanowire junctions
Erik C. Garnett,Wenshan Cai,Judy J. Cha,Fakhruddin Mahmood,Fakhruddin Mahmood,Stephen T. Connor,M. Greyson Christoforo,Yi Cui,Yi Cui,Michael D. McGehee,Mark L. Brongersma +10 more
TL;DR: A light-induced plasmonic nanowelding technique is demonstrated to assemble metallic nanowires into large interconnected networks and opens new avenues to control light, heat and mass transport at the nanoscale.
Journal ArticleDOI
First-row transition metal dichalcogenide catalysts for hydrogen evolution reaction
TL;DR: A group of first-row transition metal dichalcogenides (ME2, M = Fe, Co, Ni; E = S, Se) were introduced as non-precious HER catalysts in an acidic electrolyte.
