Characterization of the stellar variability in CoRoT fields with BEST telescopes
(Univ. Berlin, 2009)The first extrasolar planet 51 Peg b around the G-type star has been reported in 1995. The planet with few Jupiter masses orbiting its star very closely was detected by measurement of the oscillation in the radial velocity ... -
Characterization on organic matrix proteins enclosed in high Mg-calcite crystals of the coralline sponge Spirastrella (Acanthochaetetes) wellsi

Characterization on organic matrix proteins enclosed in high Mg-calcite crystals of the coralline sponge Spirastrella (Acanthochaetetes) wellsi
(Globale und regionale Steuerungsfaktoren biogener Sedimentation, 1996)Protein components found in freeze-dried specimens of the coralline sponge Spirastrella (Acanthochaetetes) wellsi were separated and characterized . Proteins extracted from skeleton crystals (matrix proteins) contained ... -
Characterizing As, Cu, Fe and U solubilization by natural waters
(Springer-Verlag, Berlin/HeidelbergSpringer, Berlin/Heidelberg2008)The effects of carbonate concentration and the presence of in-situ generated iron oxide and hydroxide phases (iron oxyhydroxides) on arsenic (As), copper (Cu), and uranium (U) release from natural rocks were investigated ... -
Characterizing As, Cu, Fe and U solubilization by natural waters
(Uranium, Mining and Hydrogeology, 2008)The effects of carbonate concentration and the presence of in-situ generated iron oxide and hydroxide phases (iron oxyhydroxides) on arsenic (As), copper (Cu), and uranium (U) release from natural rocks were investigated ... -
Characterizing hydrological processes within kettle holes using stable water isotopes in the Uckermark of northern Brandenburg, Germany
(Hydrological Processes, 2020-02-18)Understanding the hydrologic connectivity between kettle holes and shallow groundwater, particularly in reaction to the highly variable local meteorological conditions, is of paramount importance for tracing water in a ... -
Characterizing the discoloration of methylene blue in Fe0/H2O systems.
(Journal of hazardous materials, 2009)Methylene blue (MB) was used as a model molecule to characterize the aqueous reactivity of metallic iron in Fe(0)/H(2)O systems. Likely discoloration mechanisms under used experimental conditions are: (i) adsorption onto ... -
Characterizing the effects of shaking intensity on the kinetics of metallic iron dissolution in EDTA.
(Journal of hazardous materials, 2009-10-30)Despite two decades of intensive laboratory investigations, several aspects of contaminant removal from aqueous solutions by elemental iron materials (e.g., in Fe(0)/H2O systems) are not really understood. One of the main ... -
Characterizing the reactivity of metallic iron in Fe0/EDTA/H2O systems with column experiments
(Chemical Engineering Journal, 2010)Characterizing the intrinsic reactivity of iron materials for environmental remediation has received relative little interest. Available results are mostly based on the removal extent of selected contaminants in batch ... -
Characterizing the reactivity of metallic iron in Fe0/UVI/H2O systems by long-term column experiments
(Chemical Engineering Journal, 2011)Aqueous iron corrosion has been identified as a powerful process for environmental remediation and safe drinking water provision. The intrinsic reactivity of conventional micro-scale metallic iron (Fe0) has been mostly ... -
Characterizing the reactivity of metallic iron upon methylene blue discoloration in Fe0/MnO2/H2O systems.
(Journal of hazardous materials, 2009-09-15)A simple method is proposed for testing the reactivity of elemental iron materials (Fe(0) materials) using methylene blue (MB) as reagent. The method is based on the oxidative reactivity of Fe(II) for reductive dissolution ... -
Characterizing uranium solubilization under natural near oxic conditions
(Uranium in the Environment, 2006)A 782 d solubilization study using not shaken batch experiments and involving one uranium-bearing rock and three natural carbonate minerals was conducted to characterize uranium (U) leaching under oxic conditions. Results ... -
Characterizing Water Flow in Vegetated Lysimeters with Stable Water Isotopes and Modeling
(Groundwater, 2019)We have used stable water isotopes (δ18O, δ2H) in combination with lumped-parameter modeling for characterizing unsaturated flow in two lysimeters vegetated with maize. The lysimeters contained undisturbed soil cores ... -

Chemical characteristics (REE, etc.) of Paleozoic and Mesozoic graywackes and sandstones from Central Europe
(Contributions to Mineralogy and Petrology, 2012)During the Variscan orogeny in Central Europe, partial melting in the lower continental crust formed granitic magmas, which intruded into the upper crust and left compounds of Ca (plus Eu2+), Mg, etc. in the lower crust. ... -
Chemical Evolution of the Exceptional Arctic Stratospheric Winter 2019/2020 Compared to Previous Arctic and Antarctic Winters
(Journal of Geophysical Research: Atmospheres, 2021-09-21)The winter 2019/2020 showed the lowest ozone mixing ratios ever observed in the Arctic winter stratosphere. It was the coldest Arctic stratospheric winter on record and was characterized by an unusually strong and long‐lasting ... -
