Calcite Growth Kinetics: Dependence on Saturation Index, Ca2+:CO32– Activity Ratio, and Surface Atomic Structure
It is becoming increasingly clear that the rate of crystal growth, even at constant saturation, varies with pH, ionic strength, and solution stoichiometry. Here, we contribute to the limited data set…

The construction of periodic unfolding operators on some compact Riemannian manifolds
Abstract. The notion of periodic unfolding has become a standard tool in the theory of periodic homogenization. However, all the results obtained so far are only applicable to the “flat” Euclidean…

The mechanisms of crystal growth inhibition by organic and inorganic inhibitors
TLDR
A microkinetic model is used to study the mechanisms of several inhibitors of calcite growth, finding that the processes are quite different for inorganic and organic inhibitors.

Calcite Wettability in the Presence of Dissolved Mg2+ and SO42-
The wettability of mineral surfaces controls a range of phenomena in natural and industrial processes. In reservoirs, rock wettability determines the effectiveness of oil production; thus,…

First-principles prediction of surface wetting.
TLDR
This model takes into account the solvation contributions and can be used to predict wetting behavior for a solid surface in contact with two liquids, based on density functional theory and the implicit solvent model COSMO-RS.

Salinity-Dependent Adhesion Response Properties of Aluminosilicate (K-Feldspar) Surfaces
Flooding sandstone oil reservoirs with low salinity water can lead to a significant increase in oil recovery, a phenomenon called “the low salinity effect”. Although there are many factors that…

A Microkinetic Model of Calcite Step Growth.
TLDR
A microkinetic model is presented that accurately reproduces calcite growth over a very wide range of published experimental data for solution composition, saturation index, pH and impurities and demonstrates that polynuclear complexes play a central role in mineral growth at high supersaturation.

Adaptive center determination for effective suppression of ring artifacts in tomography images
Ring artifacts on tomogram slices hinder image interpretation. They are caused by minor variation in the response from individual elements in a two dimensional (2D) X-ray detector. Polar space…
