Hydrothermal Synthesis of Cobalt ‎Disulfide Nanostructures and Adsorption ‎Kinetics, Isotherms, and Thermodynamics ‎of Tetracycline‎

   Surfaces of synthesis cobalt disulfide has high electron density that could interact with polycyclic aromatic compounds by π-π stacking. Cobalt disulfide was synthesized with the hydrothermal method and characterized by field emission scanning electron microscopy, X-ray diffraction and energy-dispersive X-ray. Using tetracycline as a model analyte, the batch adsorption experiments were c...

Chromium isotope fractionation during subduction-related metamorphism, black shale weathering, and hydrothermal alteration

Article history: Received 28 June 2015 Received in revised form 4 January 2016 Accepted 8 January 2016 Available online 12 January 2016 Chromium (Cr) isotopes are an emerging proxy for redox processes at Earth's surface. However, many geological reservoirs and isotope fractionation processes are still not well understood. The purpose of this contribution is to move forward our understanding of ...

Laboratory Hydrothermal Alteration of Basaltic Tephra by Acid Sulfate Solutions: an Analog Process for Martian Weathering

Introduction: Sulfur is a major chemical component of the Martian surface materials and is thought to have a volcanic origin. Pathfinder and Viking chemical analyses revealed SO3 compositions of “soils” and dust from about 4 to over 7 wt. % [1,2]. Although we know that S is chemically important, we do not know its speciation. Small amounts of sulfates (e.g., Ca and Mg sulfates) and sulfides (e....
