Niobium nitride based thin films deposited by DC reactive magnetron sputtering

Due to their high hardness, high melting point and high chemical stability, transition metal nitrides present a great interest for various applications. This work constitutes a contribution to the understanding of the properties of Nb based binary and tern ...

Frontiers of Optical Spectroscopy: Investigating Extreme Physical Conditions with Advanced Optical Techniques

We present a review of wave packet dynamics in different systems and stress their relation to information on the ultrafast structural changes. We show how dynamical information is obtained from ultrafast optical pump-probe studies on structural changes in ...

Synthesis, characterization of dihydrolipoic acid capped gold nanoparticles, and functionalization by the electroluminescent luminol

Philippe Gillet, Bruno Garcia

The use of gold nanoparticles as biological probes requires the improvement of colloidal stability. Dihydrolipoic acid (DHLA), a dithiol obtained by the reduction of thioctic acid, appears therefore very attractive for the stabilization and the further fun ...

Thermal treatment of metal-enriched biomass produced from heavy metal phytoextraction

Christian Ludwig, Catherine Keller

Phytoextraction is an environmentally sound method for cleaning up sites that are contaminated with toxic heavy metals. However, the method has been questioned because it produces a biomass-rich secondary waste containing the extracted metals. Therefore, f ...

2005

Fly ash is commonly deposited in special landfills as it contains toxic concentrations of heavy metals, such as Zn, Pb, Cd, and Cu. This study was inspired by our efforts to detoxify fly ash from municipal solid waste incineration by thermal treatment to p ...

Synchrotron X-ray absorption of LaCoO3 perovskite

Rudolf Paul Wilhelm Jozef Struis

LaCoO3 perovskite was prepared at 700degreesC using citrate precursors. The product was then characterized with X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS). The powder XRD pattern indicates rhomboliedral (R (3) over barc) or its monocli ...

Ultrafast X-ray Absorption Spectroscopy

Majed Chergui

A review. Ultrafast x-ray techniques using diffraction and absorption are discussed with an emphasis on the absorption techniques. Ultrafast x-ray sources and detectors for use in x-ray absorption spectroscopy are also reviewed. [on SciFinder (R)] ...

Investigation of the inhibitory effect of silica on the degradation of 1,1,1-trichloroethane by granular iron

Tamar Kohn

Although iron-based permeable reactive barriers are gaining importance for treating groundwater contaminants, little is currently known about the effect of cosolutes on barrier longevity. Because of their corrosion inhibiting properties, dissolved silica s ...

Equilibrium and kinetic aspects of soddyite dissolution and secondary phase precipitation in aqueous suspension

Janet Gordon Hering

The dissolution and transformation of soddyite ([UO2]2SiO4·2H2O) have been examined in aqueous suspension at pH 6 and 0.01 M NaNO3. Soddyite is an important component of the paragenetic sequence of secondary minerals that arises from the weathering of uran ...
