Mesoskopische Strukturen in kristallinen Systemen an zwei Beispielen aus Natur und Synthese - I. Die Leitfähigkeit der ferroelastischen Domänen in Bleiphosphat; II. Oszillatorische Biomineralisation in Molluskenschalen
(Univ. Hamburg, 2006)In dieser Arbeit werden zwei mesoskopische Systeme untersucht, zum ersten die ferroelastischen Domänen in Calcium-dotiertem Bleiphosphat, zum zweiten die oszillatorische Biomineralisation im Calcit und Aragonit von ... -
Mesospheric Q2DW Interactions With Four Migrating Tides at 53°N Latitude: Zonal Wavenumber Identification Through Dual‐Station Approaches
; ; ; ; (Geophysical Research Letters, 2021-04-28)
Mesospheric winds from two longitudinal sectors at 53°N latitude are combined to investigate quasi‐two‐day waves (Q2DWs) and their nonlinear interactions with tides. In a summer 2019 case study, we diagnose the zonal ... -
Mesozoic deposits of SW Gondwana (Namibia): unravelling Gondwanan sedimentary dispersion drivers by detrital zircon
(International Journal of Earth Sciences, 2020-04-25)The Namibian Mesozoic successions may be remnant of a high dynamic sedimentary system that is characterized by multiple stages of sediment accumulation and erosion with contemporaneous homogenization starting with the ... -
Mesozoische und rezente desmentragende Demospongiae (Porifera, "Lithistidae") - (Paläobiologie, Phylogenie und Taxonomie)
(Selbstverlag Fachbereich Geowissenschaften, FU Berlin, 1993)Innerhalb der Demospongiae werden in allen höheren Kategorien Poriferen mit desmoiden Megaskleren beobachtet. Deshalb wird die polyphyletische Gruppierung der "Lithistida" (Mittelkambrium - Rezent) aufgelöst. Die in der ... -

Metabasic rocks from the Variscan Schwarzwald (SW Germany): metamorphic evolution and igneous protoliths
(International Journal of Earth Sciences, 2021-03-22)In the Variscan Schwarzwald metabasic rocks form small bodies included within anatectic plagioclase-biotite gneisses. Many metabasites first underwent an eclogite-facies metamorphism at about 2.0 GPa and 670–700 °C, resulting ... -

Metallic iron for environmental remediation: learning from electrocoagulation.
; Schöner, A. (Journal of hazardous materials, 2010-03-15)
The interpretation of processes yielding aqueous contaminant removal in the presence of elemental iron (e.g. in Fe(0)/H(2)O systems) is subject to numerous complications. Reductive transformations by Fe(0) and its primary ... -
Metallic iron for environmental remediation: learning from the Becher process.
(Journal of hazardous materials, 2009-09-15)
Metallic iron (Fe(0)) is a moderately reducing agent that has been reported to be capable of reducing many environmental contaminants. Reduction by Fe(0) used for environmental remediation is a well-known process to organic ... -
Metallic iron for environmental remediation: the long walk to evidence
(2013-06-25)
The science of metallic iron for environmental remediation is yet to be established. The prevailing theory of the Fe 0 /H 2 O system is characterized by its inability to fully rationalize the concept that holds up the ... -

Metallic iron for safe drinking water worldwide
(Chemical Engineering Journal, 2010)
A new concept for household and large-scale safe drinking water production is presented. Raw water is successively filtered through a series of sand and iron filters. Sand filters mostly remove suspended particles (media ... -
Metallic iron for water treatment and environmental remediation: A handout to young researchers
Nkundimana, Emmanuel;; Uwamariya, Valentine (Fresenius Environmental Bulletin, 2015)
The premise of this research note is that current research on metallic iron (Fe0) for environmental remediation and water treatment has started on a biased basis. Before expecting experienced researchers to correct flawed ... -
Metallic Iron for Water Treatment: A Critical Review
(CLEAN - Soil, Air, Water, 2013)
Water treatment with metallic iron (Fe0) is still based on the premise that Fe0 is a reducing agent. An alternative concept stipulates that contaminants are removed by adsorption, co-precipitation and size-exclusion in a ... -
Metallic iron for water treatment: A knowledge system challenges mainstream science
(Fresenius Environmental Bulletin, 2011)
A knowledge system (KS) is a knowledge that is unique to a given group of persons. This form of knowledge may have a local or natural origin and is linked to the community that has produced it. On the contrary, the core ... -
Metallic iron for water treatment: Healing a research community
(Journal of New Developments in Chemistry, 2014)
Despite two decades of intensive research on using metallic iron (Fe0) for environmental remediation and water treatment, basic concerns about their efficiency still prevail. This communication presents the basic idea of ... -
