Spinel–rock salt transformation in LiCoMnO4−δ

The transformation on heating LiCoMnO4, with a spinel structure, to LiCoMnO3, with a cation-disordered rock salt structure, accompanied by loss of 25% of the oxygen, has been followed using a combination of diffraction, microscopy and spectroscopy techniques. The transformation does not proceed by a topotactic mechanism, even though the spinel and rock salt phases have a similar, cubic close-pa...

On 4 - γt - Critical Graphs of Order 4 + Δ ( G )

A graph G with no isolated vertex is total domination vertex critical if for any vertex v of G that is not adjacent to a vertex of degree one, the total domination number of G− v is less than the total domination number of G. We call these graphs total domination critical or just γt-critical. If such a graph G has total domination number k, we call it k-γt-critical. We study an open problem of ...

Interstitialcy diffusion of oxygen in tetragonal La2CoO(4+δ).

We report on the mechanism and energy barrier for oxygen diffusion in tetragonal La(2)CoO(4+δ). The first principles-based calculations in the Density Functional Theory (DFT) formalism were performed to precisely describe the dominant migration paths for the interstitial oxygen atom in La(2)CoO(4+δ). Atomistic simulations using molecular dynamics (MD) were performed to quantify the temperature ...

Layered-to-Rock-Salt Transformation in Desodiated NaxCrO2 (x 0.4)

O3 layered sodium transition metal oxides (i.e., NaMO2, M = Ti, V, Cr, Mn, Fe, Co, Ni) are a promising class of cathode materials for Na-ion battery applications. These materials, however, all suffer from severe capacity decay when the extraction of Na exceeds certain capacity limits. Understanding the causes of this capacity decay is critical to unlocking the potential of these materials for b...

Universal magnetic properties of La 2 − δ Sr δ CuO 4 at intermediate temperatures .

We present the theory of two-dimensional, clean quantum antiferromagnets with a small, positive, zero temperature (T ) stiffness ρs, but with the ratio kBT/ρs arbitrary. Universal scaling forms for the uniform susceptibility (χu), correlation length(ξ), and NMR relaxation rate (1/T1) are proposed and computed in a 1/N expansion and by Monté-Carlo simulations. For large kBT/ρs, χu(T )/T and Tξ(T...
