Journal ArticleDOI
An orthophosphate semiconductor with photooxidation properties under visible-light irradiation
Zhiguo Yi,Jinhua Ye,Naoki Kikugawa,Tetsuya Kako,Shuxin Ouyang,Hilary Stuart-Williams,Hiu Yang,Junyu Cao,Wenjun Luo,Zhaosheng Li,Yun Liu,Raymond Withers +11 more
TL;DR: Ag(3)PO(4) semiconductor is reported, which can harness visible light to oxidize water as well as decompose organic contaminants in aqueous solution, and its potential as a photofunctional material for both water splitting and waste-water cleaning is suggested.
Journal ArticleDOI
Constraints on the superconducting order parameter in Sr2RuO4 from oxygen-17 nuclear magnetic resonance
Andrej Pustogow,Yi Luo,Yi Luo,Aaron Chronister,Yue-Shun Su,Dmitry A. Sokolov,Fabian Jerzembeck,Andrew P. Mackenzie,Andrew P. Mackenzie,Clifford W. Hicks,Naoki Kikugawa,Srinivas Raghu,Eve Bauer,Stuart Brown +13 more
TL;DR: NMR spectroscopy of oxygen-17 reveals a drop of the Knight shift in the superconducting state, contradicting previous work and imposing tight constraints on the order parameter symmetry of the system.
Journal ArticleDOI
Nitrogen-doped Lamellar Niobic Acid with Visible Light-responsive Photocatalytic Activity
Journal ArticleDOI
A comparison study of rhodamine B photodegradation over nitrogen-doped lamellar niobic acid and titanic acid under visible-light irradiation.
TL;DR: The results of the current study suggest that the protonic acidity of the lamellar solid-acid sample is a key factor that influences nitrogen doping and the resultant visible-light photocatalysis.
Journal ArticleDOI
Evolution of the Fermi surface and quasiparticle renormalization through a van Hove singularity in Sr2-yLayRuO4.
Kang Shen,Kang Shen,Naoki Kikugawa,C. Bergemann,Luis Balicas,Felix Baumberger,Felix Baumberger,Worawat Meevasana,N. J. C. Ingle,N. J. C. Ingle,Y. Maeno,Zhi-Xun Shen,Andrew P. Mackenzie +12 more
TL;DR: It is proved that the Fermi level in the gamma band of Sr(2-y)La(y)RuO(4) can be made to traverse a van Hove singularity and the large mass renormalization has little dependence on either k or doping.
