Concerted Metal Cation Desorption and Proton Transfer on Deprotonated Silica Surfaces [PDF]
Journal of Physical Chemistry Letters 9(18), 5379-5385 (2018), 2018 The adsorption equilibrium constants of monovalent and divalent cations to material surfaces in aqueous media are central to many technological, natural, and geochemical processes. Cation adsorption/desorption is often proposed to occur in concert with proton-transfer on hydroxyl-covered mineral surfaces, but so far this cooperative effect has been ...

Proton-transfer Ferroelectricity / Multiferroicity in Rutile Oxyhydroxides [PDF]
, 2018 Oxyhydroxide minerals like FeOOH have been a research focus in geology for studying the Earth interior, and also in chemistry for studying oxygen electrocatalysis activity. In this paper we provide first-principles evidence of a new class of ferroelectrics or multiferroics among them:GaOOH,InOOH,CrOOH,FeOOH, which are earth-abundant minerals and have ...

Physical Characterization of Metal-rich Near-Earth Asteroids 6178 (1986 DA) and 2016 ED85 [PDF]
arXiv, 2021 Metal-rich near-Earth asteroids (NEAs) represent a small fraction of the NEA population that is mostly dominated by S- and C-type asteroids. Because of this, their identification and study provide us with a unique opportunity to learn more about the formation and evolution of this particular type of bodies, as well as their relationship with meteorites

2D Vermiculite Nanolaminated Membranes for Efficient Organic Solvent Nanofiltration
Advanced Functional Materials, EarlyView.Intercalating multivalent cations into 2D vermiculite nanolaminates significantly improves the structural stability and sieving capabilities of membranes in both aqueous and organic media, rendering them effective for organic solvent nanofiltration. Abstract Membrane separation technology has found widespread application in molecular sieving and water ...
