Investigation into the thermal dehydroxylation and decomposition of hydroxylapatite during atmospheric plasma spraying
(TU Freiberg, 2004)
Hydroxylapatite (HA) is a frequently used bioceramic material for replacement of bone matter subjected to low loading conditions, for osseoconductive coatings on implants and for utilisation as a drug carrier. Plasma ...
Processes of Contaminant Removal in Fe0-H2O Systems Revisited: The Importance of Co-Precipitation
(
- The open environmental journal
, 2007)
The mechanism of aqueous contaminant removal by elemental iron (Fe0) materials (e.g., in Fe0-H2O systems) has been largely discussed in the iron technology literature. Two major removal mechanisms are usually discussed: ...
On the validity of specific rate constants (kSA) in Fe0/H2O systems
(
- Journal of hazardous materials
, 2009)
The validity of the specific reaction rate constants (kSA) in modelling contaminant removal in Fe0/H2O systems is questioned. It is shown that the current kSA-model does not consider the large reactive surface area provided ...
Implications of Reactions Between SO2 and Basaltic Glasses for the Mineralogy of Planetary Crusts
(
- Journal of Geophysical Research: Planets
, 2019)
Basalts are ubiquitous in volcanic systems on several planetary bodies, including the Earth, Mars, Venus, and Jupiter's moon Io, and are commonly associated with sulfur dioxide (SO2) degassing. We present the results of ...
X‐ray dichroism in polyimide caused by non‐resonant scattering
(
- Journal of Synchrotron Radiation
, 2020-12-22)
Dichroism is one of the most important optical effects in both the visible and the X‐ray range. Besides absorption, scattering can also contribute to dichroism. This paper demonstrates that, based on the example of polyimide, ...
Moisture origin and stable isotope characteristics of precipitation in southeast Siberia
(
- Hydrological Processes
, 2019-09-02)
The paper presents oxygen and hydrogen isotopes of 284 precipitation event samples systematically collected in Irkutsk, in the Baikal region (southeast Siberia), between June 2011 and April 2017. This is the first ...
The potential of ryegrass as cover crop to reduce soil N2O emissions and increase the population size of denitrifying bacteria
(
- European Journal of Soil Science
, 2020-11-05)
Nitrogen (N) fertilization is the major contributor to nitrous oxide (N2O) emissions from agricultural soil, especially in post‐harvest seasons. This study was carried out to investigate whether ryegrass serving as cover ...
Laboruntersuchungen zur Freisetzung von Unat aus einem Gestein unter oxischen naturnahen Bedingungen
(
- Grundwasser
, 2005)
The effects of carbonate concentration and the presence of iron hydroxide phases on uranium release into the environment were investigated under oxic conditions and in the pH range from 6 to 9. For this purpose not-shaken ...
High-Resolution Imaging of Texture and Microstructure by the Moving Detector Method
(
- Textures and Microstructures
, 2003)
In order to describe texture and microstructure of a polycrystalline material completely, crystal orientation g={?1F?2} must be known in all points x={x1?x2?x3} of the material. This can be achieved by locationresolved ...
