Reversible adapting layer produces robust single-crystal electrocatalyst for oxygen evolution.

TL;DR: It is reported that single-crystal Co3O4 nanocube underlay with a thin CoO layer results in a high-performance and high-stability electrocatalyst in oxygen evolution reaction, which exhibits stable, continuous oxygen evolution for >1,000 h.
Journal ArticleDOI

Origin of Thermal Degradation of Sr2–xSi5N8:Eux Phosphors in Air for Light-Emitting Diodes

TL;DR: The origin of the thermal degradation in Sr(2-x)Si(5)N(8):Eu(x) with x = 0.10 is due to the formation of an amorphous layer on the surface of the nitride phosphor grain during oxidative heating treatment, which results in the oxidation of Eu ions from divalent to trivalent.
Journal ArticleDOI

In-Situ X-ray Absorption Spectroscopic Study on Variation of Electronic Transitions and Local Structure of LiNi1/3Co1/3Mn1/3O2 Cathode Material during Electrochemical Cycling

TL;DR: In this paper, the changes of the electronic transitions and local structure at the Mn, Co, and Ni K-edge for the LiNi1/3Co 1/3Mn1/ 3O2 electrode during charging and discharging process were examined.
Journal ArticleDOI

Cation-Size-Mismatch Tuning of Photoluminescence in Oxynitride Phosphors

TL;DR: It is shown that size-mismatch between host and dopant cations tunes photoluminescence shifts systematically in M(1.95)Eu(0.05)Si(5-x)Al(x)N(8- x)O( x) lattices, leading to a red shift when the M = Ba and Sr host cations are larger than the Eu(2+) dopant, but a blue shift when that host is smaller.
