Size dependent spinodal decomposition in Cu-Ag nanoparticles

Size-dependent spinodal and miscibility gaps for intercalation in nanoparticles.

Using a recently proposed mathematical model for intercalation dynamics in phase-separating materials ( Singh , G. K. , Ceder , G. and Bazant , M. Z. Electrochimica Acta 2008 , 53 , 7599. ), we show that the spinodal and miscibility gaps generally shrink as the host particle size decreases to the nanoscale. Our work is motivated by recent experiments on the high-rate Li-ion battery material LiF...

Size Dependent ø(3) for Conduction Electrons in Ag Nanoparticles

Our theoretical study of the third-order susceptibility (ø(3)) for Ag dielectric composite reveals a critical role of saturation of optical transitions between discrete states of conduction electrons in metal quantum dots. The calculated size dependence of the ø(3) for Ag nanoparticles reproduces the published experimental results. Saturation effects lead to a decrease of the local field enhanc...

Programs for the calculation of the spinodal decomposition growth rate and the spinodal gap in nanoparticles

This data article contains the programs for the calculation of the spinodal decomposition growth rate and for the modeling of the spinodal gap and concentration profiles in nanoparticles which were used in our article (Pogorelov et al., 2017) [1]. The modeling is based on the mathematical model of spinodal phase decomposition with intercalation rate conditions on the boundaries (Singh et al., 2...

Spinodal decomposition in microemulsions

Parallel Spinodal Decomposition

Spinodal decomposition encompasses the ordering dynamics of thermodynamically unstable phases. An example of spinodal decomposition is the separation of the metals in a binary alloy. Because physicists have been unable to develop a fully coherent, consistent , and calculable theory on spinodal decomposition, computational studies have served as valuable sources of information. However, since th...
