Journal ArticleDOI
Nanoporous Copper with Tunable Nanoporosity for SERS Applications
TL;DR: In this article, the effect of acid concentration and etching potential on the formation of nanoprosity is systematically investigated and it is reported that nanoporous copper with a tunable nanopore size can be fabricated by controlling the dealloying process.
Journal ArticleDOI
Grain rotation mediated by grain boundary dislocations in nanocrystalline platinum
TL;DR: At atomic-scale images, it is demonstrated directly that the evolution of the misorientation angle between neighbouring grains can be quantitatively accounted for by the change of the Frank–Bilby dislocation content in the grain boundary.
Journal ArticleDOI
Atomic structure of nanoclusters in oxide-dispersion-strengthened steels
TL;DR: This study provides compelling evidence that the nanoclusters have a defective NaCl structure with a high lattice coherency with the bcc steel matrix, which seems to be the most important reasons for the unusual stability of the clusters at high temperatures and in intensive neutron irradiation fields.
Journal ArticleDOI
A Layered P2- and O3-Type Composite as a High-Energy Cathode for Rechargeable Sodium-Ion Batteries
Shaohua Guo,Pan Liu,Haijun Yu,Yanbei Zhu,Mingwei Chen,Masayoshi Ishida,Haoshen Zhou,Haoshen Zhou,Haoshen Zhou +8 more
TL;DR: A layered composite with P2 and O3 integration is proposed toward a sodium-ion battery with high energy density and long cycle life, which can deliver a high reversible capacity and good capacity retention over 150 times of sodium extraction and insertion.
Journal ArticleDOI
Zinc-Mediated Template Synthesis of Fe-N-C Electrocatalysts with Densely Accessible Fe-Nx Active Sites for Efficient Oxygen Reduction.
Guangbo Chen,Pan Liu,Zhongquan Liao,Fanfei Sun,Yanghua He,Haixia Zhong,Tao Zhang,Ehrenfried Zschech,Mingwei Chen,Gang Wu,Jian Zhang,Jian Zhang,Xinliang Feng +12 more
TL;DR: Here, a novel zinc-mediated template synthesis strategy is demonstrated for constructing densely exposed Fe-Nx moieties on hierarchically porous carbon (SA-Fe-NHPC) that exhibits an unprecedentedly high ORR activity with a half-wave potential of 0.93 V in a 0.1 m KOH aqueous solution.
