DOI: 10.1016/j.actamat.2018.09.051
Abstract: Abstract Different point defect interactions were found to govern the defect chemistry of SrFeO3-δ and La0.6Sr0.4FeO3-δ. Conventional defect structure model based on two reactions – oxygen release by oxide lattice and the charge disproportionation in… read more here.

DOI: 10.1038/s41598-020-68812-7
Abstract: In this study, molecular dynamics simulations were performed to understand the defect structure development of polyacrylonitrile-single wall carbon nanotube (PAN-SWNT) nanocomposites. Three different models (control PAN, PAN-SWNT(5,5), and PAN-SWNT(10,10)) with a SWNT concentration of 5… read more here.
