Pore-scale modelling of ostwald ripening
WebDevelopments in the theory of Ostwald ripening since the classic work of I. M. Lifshitz and V. V. Slyozov (LS) are reviewed and directions for future work are suggested. Recent theoretical work on the role of a finite volume fraction of coarsening phase on the ripening behavior of two-phase systems is reformulated in terms of a consistent set of notation through which … WebDec 17, 2024 · Here, we describe the size-dependent, electrochemically controlled Ostwald ripening of 1.6, 4, and 15 nm-diameter Au nanoparticles (NPs) attached to (3-aminopropyl)triethoxysilane (APTES)-modified glass/indium-tin-oxide electrodes. Holding the Au NP-coated electrodes at a constant negative potential …

WebOstwald ripening is a mechanism that could potentially cause remobilization. We compare the case of bubbles of gas in a free liquid to that of a solid porous matrix. Using a new continuous pore network model, we gain insights on Ostwald Ripening in rocks and estimate time scales of evolution of multi-ganglia systems. Web15 and 25 bar are presented in B. and C. respectively. Though hardly visible, the measured Xenon signal in the pores of the core differs from the void signal at the same pressure as a consequence of pseudo-enhancement. At 15 and 25 bar the Xenon in the pores has a higher (brighter) signal than the sand grains around, opposite to the image at 1 bar.
