The Nakhlite Hydrothermal Brine

Introduction: Mineralogical studies have demonstrated that the nakhlite SNC meteorites have preserved the effects of water-rock interaction between a hydrothermal brine and the nakhlite parent rocks on Mars. Brittle fracturing and corrosion of olivine grains and mesostasis associated with the hydrothermal event have left veins of zoned Fe-carbonate, Fe-smectite (with minor serpentine), and an a...

Mars Brine Formation Experiment

Forward Osmosis Brine Drying

The Forward Osmosis Brine Drying (FOBD) system is based on a technique called forward osmosis (FO). FO is a membrane-based process where the osmotic potential between brine and a salt solution is equalized by the movement of water from the brine to the salt solution. The FOBD system is composed of two main elements, the FO bag and the salt regeneration system. This paper discusses the results o...

Formation of brine channels in sea ice.

Liquid salty micro-channels (brine) between growing ice platelets in sea ice are an important habitat for CO2-binding microalgaea with great impact on polar ecosystems. The structure formation of ice platelets is microscopically described and a phase field model is developed. The pattern formation during solidification of the two-dimensional interstitial liquid is considered by two coupled orde...

Abnormal saline: the unphysiological bag of brine

Duburcq and colleagues, in their article published in Critical Care, showed improved oxygenation, hemodynamic parameters, and microvascular reactivity in an experimental porcine endotoxic shock model with use of hypertonic sodium lactate 11.2% [1]. We applaud the authors for embarking on the arduous quest for the ideal resuscitative fluid, which has historically been fraught with shortcomings. ...
