Visualizing the Role of Bi 6s “Lone Pairs” in the Off-Center Distortion in Ferromagnetic BiMnO3
Ram Seshadri,Nicola A. Hill +1 more
TL;DR: In this article, the role of electron lone pairs in stabilizing the highly distorted perovskite structure is examined using real-space visualization of the electronic structure, drawing comparisons with the electronic structures of hypothetical cubic BiMnO3 and with the prototypical perovsite manganite, LaMn O3.
Journal ArticleDOI
Phosphors for Solid-State White Lighting
TL;DR: A review of the current needs and key aspects of the conversion process is given in this paper, where the authors describe some currently used families of phosphors and consider why they are suitable for solid-state lighting.
Journal ArticleDOI
Ordered mesoporous metallic MoO2 materials with highly reversible lithium storage capacity.
Yifeng Shi,Bingkun Guo,Serena A. Corr,Qihui Shi,Yong-Sheng Hu,Kevin Ray Heier,Liquan Chen,Ram Seshadri,Galen Stucky +8 more
TL;DR: Primary test found that mesoporous MoO(2) material exhibits a reversible electrochemical lithium storage capacity as high as 750 mA h g(-1) at C/20 after 30 cycles, rendering it as a promising anode material for lithium ion batteries.
Journal ArticleDOI
The role of magnesium in stabilising amorphous calcium carbonate and controlling calcite morphologies
TL;DR: In this article, it was demonstrated that amorphous calcium carbonate (ACC) was the first phase formed and the magnesium content of the ACC was defined by the Mg:Ca ratio in the solution.
Journal ArticleDOI
Crystal structure and the paraelectric-to-ferroelectric phase transition of nanoscale BaTiO3.
Millicent B. Smith,Katharine Page,Theo Siegrist,Peter L. Redmond,Erich C. Walter,Ram Seshadri,Louis E. Brus,Michael L. Steigerwald +7 more
TL;DR: Although structural distortions are robust to changes in particle size, what is affected is the coherency of the distortions, which is decreased in the smaller particles, in contrast to the sharp transition that is found for the bulk sample.
