Three-dimensional topological insulators in the octahedron-decorated cubic lattice

, 2011
We investigate a tight-binding model of the octahedron-decorated cubic lattice with spin-orbit coupling. We calculate the band structure of the lattice and evaluate the Z_2 topological indices.

Synergistic Effects of Entropy Tuning in Niobium‐Based Oxide Anode for Fast‐Charging Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
An entropy‐tuned niobium‐based oxide (ETNO) anode for fast‐charging lithium‐ion batteries are presented, engineered via multi‐cation doping. The synergistic effects of entropy tuning result in excellent rate capability and long‐term durability under ultrafast charging conditions.

Computational Analysis of Composition-Structure-Property-Relationships in NZP-type Materials for Li-Ion Batteries

, 2019
Compounds crystallizing in the structure of NaZr$_2$(PO$_4$)$_3$ (NZP) are considered as promising materials for solid state electrolytes in Li-ion batteries. Using density functional theory (DFT), a systematic computational screening of 18 NZP compounds,

Remodeling Interfacial Electrical Field for Superhigh Capacity and Ultralong Lifespan Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
The design of cathode materials is the key to solving the practical application of AZIBs. In this work, the formation of the built‐in electric field in the NVO@CC material adjusts the electronic structure, showing high specific capacity and ultra‐long cycle stability, and achieving rapid diffusion of ions and good electrochemical kinetics.

Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6

Advanced Functional Materials, EarlyView.
This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...
