Machine learning-assisted discovery of many new solid Li-ion conducting materials
Austin D. Sendek, Ekin D. Cubuk, Evan R. Antoniuk +3
We discover many new crystalline solid materials with fast single crystal Li ion conductivity at room temperature, discovered through density functional theory simulations guided b…
Bright sub-20 nm cathodoluminescent nanoprobes for multicolor electron microscopy
Maxim B. Prigozhin, Peter C. Maurer, Alexandra M. Courtis +18
Electron microscopy (EM) has been instrumental in our understanding of biological systems ranging from subcellular structures to complex organisms. Although EM reveals cellular mor…
First-principles Approaches to Simulate Lithiation in Silicon Electrodes
Qianfan Zhang, Yi Cui, Enge Wang
Silicon is viewed as an excellent electrode material for lithium batteries due to its high lithium storage capacity. Various Si nano-structures, such as Si nanowires, have performe…
LiMn1-xFexPO4 Nanorods Grown on Graphene Sheets for Ultra-High Rate Performance Lithium Ion Batteries
Hailiang Wang, Yuan Yang, Yongye Liang +6
Following the successful utilization of LiFePO4 as a novel cathode material for rechargeable lithium batteries, interest and efforts have grown in the research of another olivine s…
Graphene-Wrapped Sulfur Particles as a Rechargeable Lithium-Sulfur-Battery Cathode Material with High Capacity and Cycling Stability
Hailiang Wang, Yuan Yang, Yongye Liang +5
We report the synthesis of a graphene-sulfur composite material by wrapping polyethyleneglycol (PEG) coated submicron sulfur particles with mildly oxidized graphene oxide sheets de…
Rapid Surface Oxidation as a Source of Surface Degradation Factor for Bi2Se3
Desheng Kong, Judy J. Cha, Keji Lai +8
Bi2Se3 is a topological insulator with metallic surface states residing in a large bulk bandgap. It is believed that Bi2Se3 gets additional n-type doping after exposure to atmosphe…
