Fig. 5: Mineralization of barite in the pore network.
From: Microfluidic investigation of pore-size dependency of barite nucleation
a Tracer test (fluorescent dye) conducted before experiments to illustrate the diffusion of solutes across the pore network with a decrease in intensity from left to right; b number of large and small pores containing precipitates after 3 h in experiments with different SI ranges; c micrographs representative of the experiments showing the trends in the location of precipitates as a function of the saturation index (SI); d micrographs of temporal evolution at a selected location from an experiment with 2.4 < SI < 3.2 with arrows indicating the formation of crystallites on the surface of the PDMS.
