Journal ArticleDOI
Microscopic Evidence for Liquid-Liquid Separation in Supersaturated CaCO3 Solutions
Adam F. Wallace,Adam F. Wallace,Lester O. Hedges,Alejandro Fernandez-Martinez,Alejandro Fernandez-Martinez,Paolo Raiteri,Julian D. Gale,Glenn A. Waychunas,Stephen Whitelam,Jillian F. Banfield,Jillian F. Banfield,James J. De Yoreo,James J. De Yoreo +12 more
TL;DR: This study uses molecular dynamics simulations to probe the structure, dynamics, and energetics of hydrated CaCO3 clusters and lattice gas simulations to explore the behavior of cluster populations before nucleation and predicts formation of a dense liquid phase through liquid-liquid separation within the concentration range in which clusters are observed.
Journal ArticleDOI
Selenium environmental cycling and bioavailability: a structural chemist point of view
TL;DR: In this article, a review of the important advances made during these last years in the mechanistic understanding of processes which govern selenium cycling and bioavailability, such as adsorption at the mineral/water interface, precipitation of elemental Selenium, or bioavailability of nanoscaled precipitates, is presented.
Journal ArticleDOI
Electron transfer at the mineral/water interface: Selenium reduction by ferrous iron sorbed on clay
Laurent Charlet,Andreas C. Scheinost,Christophe Tournassat,Jean-Marc Greneche,Antoine Géhin,Alejandro Fernandez-Martinez,S. Coudert,Delphine Tisserand,Jocelyne Brendle +8 more
TL;DR: In this article, the authors investigated the long-term kinetics of selenite ( Se(IV)O 3 - ) sorption to montmorillonite in the presence of Fe2+ under anoxic conditions.
Journal ArticleDOI
Recovery of Rare Earth Elements and Yttrium from Passive-Remediation Systems of Acid Mine Drainage
Carlos Ayora,Francisco Macías,Ester Torres,Alba Lozano,Sergio Carrero,J.M. Nieto,Rafael Pérez-López,Alejandro Fernandez-Martinez,Hiram Castillo-Michel +8 more
TL;DR: The findings suggest that the proposed AMD remediation process can represent a modest but suitable REY source, and the IPB could function as a giant heap-leaching process of regional scale in which rain and oxygen act as natural driving forces with no energy investment.
Journal ArticleDOI
X-ray absorption and photoelectron spectroscopy investigation of selenite reduction by FeII-bearing minerals
Andreas C. Scheinost,Regina Kirsch,Dipanjan Banerjee,Alejandro Fernandez-Martinez,Harald Zaenker,Harald Funke,Laurent Charlet +6 more
TL;DR: Comparison of these spectroscopic results with thermodynamic equilibrium modeling provides evidence that the nature of reduction end product in these FeII systems is controlled by the concentration of HSe(-); Se0 forms only at lower HSe(-) concentrations related to slower HSeO3(-) reduction kinetics.
