The double-resonance Raman spectra in single-chirality (n, m) carbon nanotubes

, 2017
Single-chirality (n, m) carbon nanotubes exhibit the same richness in physics of graphene including an additional phenomenon: the quantum confinement of electrons and phonons along the nanotubes circumference.

Enhancing the electrochemical performance of semicoke‐based hard carbon anode through oxidation‐crosslinking strategy for low‐cost sodium‐ion batteries

Carbon Energy
Semicoke, a coal pyrolysis product, is a cost‐effective and high‐yield precursor for hard carbon used as anode in sodium‐ion batteries (SIBs). However, as a thermoplastic precursor, semicoke inevitably graphitizes during high‐temperature carbonization ...

Capacitance-enhanced sodium-ion storage in nitrogen-rich hard carbon

, 2017
We demonstrate an approach to prepare nitrogen-rich hard carbon (N-HCS) from biomass as a robust anode material for sodium-ion batteries. A reversible capacity of similar to 520 mA h g(-1) at a current density of 20 mA g(-1) along with an excellent rate ...

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...
