Inertisation of heavy metals in municipal solid waste incineration fly ash by means of colloidal silica – a synchrotron X-ray diffraction and absorption study

Many efforts have been undertaken in past decades to minimize pollution from municipal solid waste incineration fly ash (MSWI FA). This residue is toxic, because of its high concentration of heavy metals, mainly Pb and Zn. A new method for heavy metals ent ...

Fe, Co, and Ni Ions Promote the Catalytic Activity of Amorphous Molybdenum Sulfide Films for Hydrogen Evolution

Xile Hu, Heron Vrubel, Stéphane Fierro, Daniel Andreas Merki, Lorenzo Rovelli

Molybdenum sulfide materials had been shown as promising non-precious catalysts for hydrogen evolution. This paper describes the study of the promotional effect of certain transition metal ions on the activity of amorphous MoS3 films. Ternary metal sulfide ...

The role of roots in the phytoextraction of bioavailable zinc

Charlotte Pfistner

Phytoextraction is a non-invasive remediation method using plants. Phytotech Foundation and AGB in Berne are performing phytoextraction on an old landfill of a former hot dip galvanization plant, using sunflowers and tobaccos as extractors. Every year sinc ...

On the scaling of polar codes: II. The behavior of un-polarized channels

Rüdiger Urbanke, Seyed Hamed Hassani

We provide upper and lower bounds on the escape rate of the Bhattacharyya process corresponding to polar codes where transmission takes place over the the binary erasure channel. More precisely, we bound the exponent of the number of sub-channels whose Bha ...

EBSD: a powerful microstructure analysis technique in the field of solidification

Michel Rappaz, Emmanuelle Boehm Courjault, Alain Jacot, Mario Alberto Salgado Ordorica, Aurèle Mariaux, Christoph Niederberger

This paper presents a few examples of the application of electron back-scatter diffraction (EBSD) to solidification problems. For directionally solidified Al-Zn samples, this technique could reveal the change in dendrite growth directions from < 100 > to < ...

Twinned dendrite growth in binary aluminum alloys

Michel Rappaz, Mario Alberto Salgado Ordorica

The formation of twinned dendrites (feathery grains) in binary Al-Zn, Al-Mg, Al-Cu and Al-Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G approximate to 100 K cm(-1), v approximate to 1 mm s(-1), ...

Growth directions in directionally solidified Al-Zn and Zn-Al alloys near eutectic composition

Michel Rappaz, Martin Rhême

Growth directions and crystallographic orientations of solidification microstructures have been measured in Al-Zn alloy near the eutectic composition. Al dendrites in Al-92 wt.% Zn alloy were found to grow along the I 10) directions while Zn dendrites in A ...

Experimental and theoretical characterization of the Zn-Zn bond in [Zn2([eta]5-C5Me5)2]

Philip Pattison

The experimental electron density obtained from a multipole refinement of the synchrotron X-ray data for the title complex, together with theoretical ab initio calculations of the electron density at the molecular geometry obtained from neutron diffraction ...

A Promising Technique to Increase Metal Concentration and Extraction in Sunflowers

Jean-Paul Schwitzguebel, Erika Nehnevajova

Since most of the metal-hyperaccumulating wild plants only produce very low biomass and many high-yielding crops accumulate only moderate amounts of metals, the current research is mainly focused on overcoming these limitations and the optimization of meta ...
