TL;DR: In this paper, the authors measured the brine concentration in a growing ice layer and showed that the lower the plate temperature, the higher the concentration of brine trapped in the ice layer, and as the ice layers thickened the local concentration of entrapped brine falls.

TL;DR: The homoionic calcium-montmorillonite was used to synthesize a red iron oxide/clay pigment in a CO2-rich brine solution by using an agitated batch-reactor (engineer autoclave) and apparently, this oxide produced red coloration in the final product.
Abstract: The homoionic calcium-montmorillonite was used to synthesize a red iron oxide/clay pigment in a CO2-rich brine solution (0.5 M of NaCl) by using an agitated batch-reactor (engineer autoclave). The operating conditions were 15 days of reaction, 200 bars of pressure and 150 °C of temperature. SEM/EDS, STEM/EDS, XRD and Infrared Spectrometry were performed to characterize before and after reaction the solid phase. The results showed the precipitation of spherical nanoparticles (50–500 nm) of iron oxide (Fe2O3) dispersed and/or coagulated in the clay-matrix. Evidently, this oxide produced red coloration in the final product. For this case, the Fe3+ cation was provided to the aqueous solution by the dissolution of Ca-montmorillonite, particularly, the dissolution of most fine particles contained in the starting clay material. The cation exchange process and precipitation of polymorph silica were also observed.

TL;DR: In this article, the effectiveness of dilute nonionic surfactant was evaluated for wettability alteration and enhanced oil recovery in carbonates by performing a suite of measurements such as aqueous stability, surface tension, phase behavior, interfacial tension (IFT), zeta potential, contact angle, and microscopic dynamic oil liberation.
