Understanding Forest Health with Remote Sensing-Part II—A Review of Approaches and Data Models
(Remote Sensing, 2017)Stress in forest ecosystems (FES) occurs as a result of land-use intensification, disturbances, resource limitations or unsustainable management, causing changes in forest health (FH) at various scales from the local to ... -
Heterogeneous vesiculation of 2011 El Hierro xeno-pumice revealed by X-ray computed microtomography
(Bulletin of Volcanology, 2016)During the first week of the 2011 El Hierro submarine eruption, abundant light-coloured pumiceous, high-silica volcanic bombs coated in dark basanite were found floating on the sea. The composition of the light-coloured ... -
Arsenic Release from a Natural Rock under Near-natural Oxidizing Conditions
(Engineering in Life Sciences, 2008)The effects of carbonate concentration and the presence of iron hydroxide phases on the process of arsenic release from an ore material were investigated under experimental oxic conditions and in the pH range from 6.0 to ... -
Reducing the ambiguity of karst aquifer models by pattern matching of flow and transport on catchment scale
(Hydrology and Earth System Sciences, 2015) -
Multi-stage emplacement of the Götemar Pluton, SE Sweden: new evidence inferred from field observations and microfabric analysis, including cathodoluminescence microscopy
(International Journal of Earth Sciences, 2011)The emplacement of the Mesoproterozoic Götemar Pluton into Paleoproterozoic granitoid host rocks of the Transscandinavian Igneous Belt is re-examined by microfabric analysis, including cathodoluminescence microscopy. Field ... -
Oxygen and Carbon Isotope Variations in a Modern Rodent Community – Implications for Palaeoenvironmental Reconstructions
(PLoS ONE, 2012-11-19)Background: The oxygen (d18O) and carbon (d13C) isotope compositions of bioapatite from skeletal remains of fossil mammals are well-established proxies for the reconstruction of palaeoenvironmental and palaeoclimatic ... -
Comments on "Stoichiometry of Cr(VI) Immobilization Using Nanoscale Zerovalent Iron (nZVI): A Study with High-Resolution X-Ray Photoelectron Spectroscopy (HR-XPS)" by Li et al. [Ind. Eng. Chem. Res. 47, 2131–2139]"
(Industrial & Engeneering Chemistry Research, 2008) -
Comment on "pH Dependence of Fenton Reagent Generation and As(III) Oxidation and Removal by Corrosion of Zero Valent Iron in Aerated Water"
(Environmental Science & Technology, 2009) -
Fe0-based alloys for Environmental Remediation: Thinking outside the Box

Biomass yield development of early, medium and late Maize varieties under a future climate in Lower Saxony, Germany
(Biogeosciences Discussions, 2014)Lower Saxony, with a total land area of about 46 500 km2, constitutes one of the most important agricultural areas in Germany and thus within Europe. Roughly one third of its agricultural area is used for maize cultivation ... -
On the Validity of Specific Rate Constants (kSA) in Fe0/H2O Systems
(Journal of Hazardous Materials, 2008)The validity of the specific reaction rate constants (k(SA)) in modelling contaminant removal in Fe-0/H2O systems is questioned. It is shown that the current k(SA)-model does not consider the large reactive surface area ... -
Greenhouse gas emissions from soils—A review
(Chemie der Erde - Geochemistry, 2016)Soils act as sources and sinks for greenhouse gases (GHG) such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). Since both storage and emission capacities may be large, precise quantifications are needed ... -
Russian boreal peatlands dominate the natural European methane budget
(Environmental Research Letters, 2016)About 60% of the European wetlands are located in the European part of Russia. Nevertheless, data on methane emissions from wetlands of that area are absent. Here we present results of methane emission measurements for ... -
Formin Is Associated with Left-Right Asymmetry in the Pond Snail and the Frog
(Current Biology, 2016)While components of the pathway that establishes left-right asymmetry have been identified in diverse animals, from vertebrates to flies, it is striking that the genes involved in the first symmetry-breaking step remain ... -
Effects of selected ligands on U (VI) immobilization by zerovalent iron
(Journal of Radioanalytical and Nuclear Chemistry, 2006) -
Efficient synthesis and reaction kinetics of readily water soluble esters containing sulfonic groups.
(Molecules (Basel, Switzerland), 2014)A series of various readily water soluble esters were synthesized by a very efficient procedure. These compounds can be useful as thermosensitive tracers for studying the cooling progress in a low enthalpy georeservoir ... -
A Rare Glimpse of Paleoarchean Life: Geobiology of an Exceptionally Preserved Microbial Mat Facies from the 3.4 Ga Strelley Pool Formation, Western Australia.
(PloS one, 2016)Paleoarchean rocks from the Pilbara Craton of Western Australia provide a variety of clues to the existence of early life on Earth, such as stromatolites, putative microfossils and geochemical signatures of microbial ... -
Deciphering fluid inclusions in high-grade rocks
(Geoscience Frontiers, 2014)The study of fluid inclusions in high-grade rocks is especially challenging as the host minerals have been normally subjected to deformation, recrystallization and fluid-rock interaction so that primary inclusions, formed ... -
Chaotic three-dimensional distribution of Ba, Rb, and Sr in feldspar megacrysts grown in an open magmatic system
(Contributions to Mineralogy and Petrology, 2011)As has been demonstrated in recent years, the heterogeneities of coeval magmas can be more successfully revealed by zoned megacrysts rather than by analysis of the whole rocks hosting them. Here, the geochemical ... -
Rescuing Fe0 remediation research from its systemic flaws
(Research and Review Insights, 2017)The well-accepted assumption of metallic iron (Fe0) acting as electron donor for environmental remediation has created an unstable domain of knowledge for the past 23 years. This assumption is discouraging some outstanding ... -
