Nucleation in confinement generates long-range repulsion between rough calcite surfaces

Fluid-induced alteration of rocks and mineral-based materials often starts at confined mineral interfaces where nm-thick water films can persist even at high overburden pressures and at low vapor pressures. These films enable transport of reactants and affect forces acting between mineral surfaces. However, the feedback between the surface forces and reactivity of confined solids is not fully understood.*

In “Nucleation in confinement generates long-range repulsion between rough calcite surfaces» Joanna Dziadkowiec, Bahareh Zareeipolgardani, Dag Kristian Dysthe and Anja Røyne describe how they used the surface forces apparatus (SFA) to follow surface reactivity in confinement and measure nm-range forces between two rough calcite surfaces in NaCl, CaCl2, or MgCl2 solutions with ionic strength of 0.01, 0.1 or 1 M.*

Roughness evolution with time of single, unconfined calcite films in salt solutions was analyzed by Atomic Force Microscopy using NANOSENSORS™ uniqprobe qp-SCONT AFM probes to image the surfaces in contact mode.*

 Figure S7 show the AFM height maps (A, B, E, F, G, J) and histograms of surface heights (C, D, H, I) of the initial set 1 (A-E) and set 2 (F-J) ALD calcite surfaces for two scan sizes of 15x15 μm2(A, C, F, H)and 2x2 μm2(B, D, E, G, I, J). The images E and J show 3D height maps of the B, G height maps, respectively
