Shear modulus, heat capacity, viscosity and structural relaxation time of Na2O–Al2O3–SiO2 and Na2O–Fe2O3–Al2O3–SiO2 melts
(
- Physics and Chemistry of Minerals
, 2010)
The configurational heat capacity, shear modulus and shear viscosity of a series of Na2O–Fe2O3–Al2O3–SiO2 melts have been determined as a function of composition. A change in composition dependence of each of the physical ...
Evolution of the tRNALeu (UAA) Intron and Congruence of Genetic Markers in Lichen-Symbiotic Nostoc.
(
- PloS one
, 2015)
The group I intron interrupting the tRNALeu UAA gene (trnL) is present in most cyanobacterial genomes as well as in the plastids of many eukaryotic algae and all green plants. In lichen symbiotic Nostoc, the P6b stem-loop ...
Recent developments in neutron imaging with applications for porous media research
(
- Solid Earth
, 2016)
Computed tomography has become a routine
method for probing processes in porous media, and the use
of neutron imaging is especially suited to the study of the
dynamics of hydrogenous fluids, and of fluids in a ...
Elemental metals for environmental remediation: learning from cementation process.
(
- Journal of hazardous materials
, 2010-09-15)
The further development of Fe(0)-based remediation technology depends on the profound understanding of the mechanisms involved in the process of aqueous contaminant removal. The view that adsorption and co-precipitation ...
On the mechanism of microbe inactivation by metallic iron
(
- Journal of Hazardous Materials
, 2011)
This letter challenges the concept that the metallic iron (Fe0) surface contributes directly to the process of micro-organism inactivation in aqueous solutions. It is shown that any antimicrobial properties of Fe0 is related ...
Testing the Suitability of Zerovalent Iron Materials for Reactive Walls
(
- Environmental Chemistry
, 2005)
Zerovalent iron (ZVI) has been proposed as reactive material in permeable in-situ walls
for contaminated groundwater. An economically feasible ZVI reactive wall requires cheap but
efficient iron materials. From an uranium ...
A horizontal gene transfer supported the evolution of an early metazoan biomineralization strategy
(
- BMC Evolutionary Biology
, 2011)
Background The synchronous and widespread adoption of the ability to biomineralize was a defining event for metazoan evolution during the late Precambrian/early Cambrian 545 million years ago. However our understanding on ...
Comment on "effect of groundwater iron and phosphate on the efficacy of arsenic removal by iron-amended biosand filters".

Imbalanced nutrients as triggers for black shale formation in a shallow shelf setting during the OAE 2 (Wunstorf, Germany)
(
- Biogeosciences
, 2012-10-29)
During the oceanic anoxic event 2 (OAE 2) in the
Mid-Cretaceous Period, widespread black shale (BS) formation
occurred, reflecting perturbations in major biogeochemical
cycles. Here we present geochemical and biomarker ...
