Effects of radiation, curvature, and preferential diffusion on the extinction of laminar non-premixed flames [PDF]
AIP Advances, 2022 The combined effects of radiative heat loss, curvature, and preferential diffusion on laminar non-premixed flames (or flamelets) are investigated in this work by using asymptotic analysis.

Direct observation of substitutional and interstitial dopant diffusion in oxide grain boundary [PDF]
Nature CommunicationsGrain boundaries (GBs) serve as fast diffusion paths for dopant atoms, and the segregated dopants can significantly alter the materials’ properties. However, the exact mechanism of fast dopant diffusion along the GBs, particularly at atomic scale, is ...
