Reversible adapting layer produces robust single-crystal electrocatalyst for oxygen evolution.
Ching-Wei Tung,Ying-Ya Hsu,Yen-Ping Shen,Yixin Zheng,Ting-Shan Chan,Hwo-Shuenn Sheu,Yuan-Chung Cheng,Hao Ming Chen +7 more
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
Chiao Wen Yeh,Wei Ting Chen,Ru-Shi Liu,Shu Fen Hu,Hwo-Shuenn Sheu,Jin-Ming Chen,Hubertus T. Hintzen +6 more
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
Photoluminescence Tuning via Cation Substitution in Oxonitridosilicate Phosphors: DFT Calculations, Different Site Occupations, and Luminescence Mechanisms
Guogang Li,Guogang Li,Chun Che Lin,Wei Ting Chen,Maxim S. Molokeev,Victor V. Atuchin,Chang Yang Chiang,Wuzong Zhou,Chin-Wei Wang,Wen-Hsien Li,Hwo-Shuenn Sheu,Ting-Shan Chan,Chong-Geng Ma,Ru-Shi Liu +13 more
TL;DR: In this article, a series of (Sr1-xBax)Si2O2N2:Eu (0 ≤ x ≤ 1) compounds were prepared by solid-state reaction, after which systematic emission variations were investigated.
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.
