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 ...

Chlorination of bromide-containing waters: Enhanced bromate formation in the presence of synthetic metal oxides and deposits formed in drinking water distribution systems

Urs von Gunten, Chao Liu

Bromate formation from the reaction between chlorine and bromide in homogeneous solution is a slow process. The present study investigated metal oxides enhanced bromate formation during chlorination of bromide-containing waters. Selected metal oxides enhan ...

Phytoextraction of zinc, zinc oxide, copper and copper oxide in hydroponic solution with gibberellic acid and EDDS amendments by Lolium perenne

Flore Alice Margot Dupuich

This work was focused on the phytoextraction of zinc, copper, zinc oxide and copper oxide by Lolium perenne cultivated in hydroponic conditions, with gibberellic acid (GA) and ethylenediamine-N,N’-disuccinic acid (EDDS) amendments tested separately and in ...

Convenient synthesis of heterobifunctional poly(ethylene glycol) suitable for the functionalization of iron oxide nanoparticles for biomedical applications

Sandrine Gerber, Davide Städler, Solène Marcelle Françoise Marie Passemard, Phally Kong, Luigi Bonacina

A straightforward route is proposed for the multi-gram scale synthesis of heterobifunctional poly(ethylene glycol) (PEG) oligomers containing combination of triethyloxysilane extremity for surface modification of metal oxides and amino or azido active end ...

Communication: Angular momentum alignment and fluorescence polarization of alkali atoms photodetached from helium nanodroplets

The theory of photofragments angular momentum polarization is applied to the photodetachment of an electronically excited alkali atom from a helium nanocluster (N = 200). The alignment of the electronic angular momentum of the bare excited alkali atoms pro ...

Enhancing Hydrophilicity of Anatase TiO2 Surfaces by Deposition of Alkaline Earths: The Case of Ca

Michel Posternak, Alfonso Baldereschi

We show with DFT calculations within the COSMO framework that the wetting energy of clean or hydroxylated anatase TiO2 surfaces is strongly enhanced by Ca deposition at low coverage. Two mechanisms contribute to this behavior: the ionic character of Ca ads ...

The impacts of acidic in-situ recovery of uranium in southern Kazakhstan on geochemistry and microbial community structure

Rizlan Bernier-Latmani, Pierre Rossi, Brian Carl Reinsch

Acidic in situ recovery (ISR) of uranium is utilized because of its potential to be much cleaner than traditional physical mining techniques. Instead of spreading uranium-laden waste rock across soil, ISR circulates acid below the surface of the Earth with ...

Deterioration of mortar bars immersed in magnesium containing sulfate solutions

Karen Scrivener, Barbara Lothenbach, Wolfgang Kunther

Mortars prepared with a CEM I and a CEM III/B binder were investigated in different magnesium sulfate solutions. The main deterioration mechanism for the CEM I was expansion, while surface erosion was dominant for CEM III/B. The presence of sodium, potassi ...

Assembly of Ligand-Stripped Nanocrystals into Precisely Controlled Mesoporous Architectures

Raffaella Buonsanti

The properties of mesoporous materials hinge on control of their compn., pore dimensions, wall thickness, and the size and shape of the crystallite building units. We create ordered mesoporous materials in which all of these parameters are independently co ...

Ordered Arrays of Size-Selected Oxide Nanoparticles

Luca Gragnaniello

A bottom-up approach to produce a long-range ordered superlattice of monodisperse and isomorphic metal-oxide nanoparticles (NP) supported onto an oxide substrate is demonstrated. The synthetic strategy consists of self-assembling metallic NP on an ultrathi ...
