Journal ArticleDOI
Selective spin-state switch and metal-insulator transition in GdBaCo 2 O 5.5
TL;DR: In this article, an anomalous expansion of the octahedra of Ba-cobaltite pyramids is observed at the phase transition on heating, while the pyramids show the normal shrinking at the closing of the gap.
Journal ArticleDOI
Local Environments of Dilute Activator Ions in the Solid-State Lighting Phosphor Y3–xCexAl5O12
Nathan C. George,Andrew J. Pell,Géraldine Dantelle,Katharine Page,Anna Llobet,Mahalingam Balasubramanian,Guido Pintacuda,Bradley F. Chmelka,Ram Seshadri +8 more
TL;DR: In this article, a combination of powerful experimental methods is determined and is correlated with the macroscopic luminescent properties of the oxide garnet Y3Al5O12 (YAG), when substituted with a few percent of the activator ion Ce3+ to replace Y3+, is shown to play a key role in the high quantum yield and resistance toward thermal quenching of luminescence.
Journal ArticleDOI
Modeling the structural evolution of carbide-derived carbons using quenched molecular dynamics
Jeremy C. Palmer,Anna Llobet,Sun-Hwa Yeon,Julia Fischer,Yunfeng Shi,Yury Gogotsi,Keith E. Gubbins +6 more
TL;DR: This article developed morphologically realistic models for amorphous carbon using quenched molecular dynamics and found that as the thermal quench rate is decreased, the model structures become more highly ordered, forming large graphene-like fragments and regularly shaped porous features.

Journal ArticleDOI
Observation of local non-centrosymmetry in weakly biferroic YCrO3
TL;DR: In this article, the average and local structure of YCrO3 has been determined using high-resolution neutron powder diffraction in order to explain the recently reported properties of the material, which is inconsistent with the development of weak electric polarization above the dielectric transition around 440 K.
