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 Production
(Freiberg Online Geosciences; Vol. 27.2011)
-
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 ... -
Metallic Iron for Water Treatment: Lost Science in the West
(Bioenergetics: Open Access, 2017)

Metamorphic gabbro and basalt in ophiolitic and continental nappes of the Zermatt region (Western Alps)
; (Swiss Journal of Geosciences, 2021-04-12)
The composition of meta-gabbro and meta-basalt occurring abundant and widespread in all nappes of the nappe stack exposed in the Zermatt region of the Western Alp shows distinct patterns related to the geodynamic origin ... -
Metapelite from the high‐ to ultrahigh‐pressure terrane of the Eastern Alps (Pohorje Mountains, Slovenia)—New pressure, temperature and time constraints on a polymetamorphic rock
; Massonne, Hans‐Joachim; Koller, Friedrich; Zhang, Junfeng (Journal of Metamorphic Geology, 2021-03-31)
The Austroalpine nappe stack of the Pohorje Mountains (Mts.) in northeastern Slovenia comprises a suite of eclogite facies metamorphic rocks that were partially assigned to Eo‐Alpine ultrahigh‐pressure metamorphism (UHPM). ... -
Metastability and HP metamorphism at fluid deficient conditions, an example from the Bergen Arcs (Western Norway)
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)In the Lindæs Nappe, Bergen Arcs Western Norway, Precambrian granulites facies anorthosites (P<10 kbars, T=800°C) and their Caledonian eclogite (P<17 kbars, T=700°C) and amphibolite facies equivalents alternate on meter scale. ... -

Methode zur Lösung lokaler Planungsprobleme im städtebaulichen Kontext
(Reimer Verlag Berlin, 1998)Die städtebaulichen Probleme, die heute zu transponieren sind, stellen sich überwiegend als unübersichtlich und vielgestaltig — komplex — dar. Für die Elaborierung dieser Probleme soll eine Darstellung entwickelt werden, ... -
Methoden und Anwendbarkeit geomorphologischer Detailkarten - Beiträge zum GMK-Schwerpunktprogramm II

Methodisch-stratigraphische Studien und paläomorphologische Untersuchungen zum Pleistozän südlich der Ostsee
(Selbstverl. des Inst. für Phys. Geographie der Freien Univ. Berlin, Berlin, 1989)Nach einer Übersicht über die methodische Entwicklung der Geschiebe- und Kieszählungen zur Erforschung der Moränenstratigraphie in pleistozän vereisten Gebieten südlich und westlich der Ostsee werden der pleistozäne ... -
Methodische Untersuchungen am Kreta-Detachment (Kreta, Griechenland): Anzeichen für eine alpidische Metamorphose der Hangendscholle
Klein, Thomas; Zulauf, Gernold; Craddock, John; (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Die Insel Kreta bildet den südlichen Rand der externen Helleniden, welche üblicherweise in zwei Deckenstapel untergliedert werden: Die unteren Decken (Plattenkalk und Phyllit-Quarzit- Einheit) sind durch eine alpidische ... -
Methods for the reconstruction of large scale anisotropies of the cosmic ray flux
(Univ. Siegen, 2010)In cosmic ray experiments the arrival directions, among other properties, of cosmic ray particles from detected air shower events are reconstructed. The question of uniformity in the distribution of arrival directions is ...
