Photoaquation Mechanism of Hexacyanoferrate(II) Ions: Ultrafast 2D UV and Transient Visible and IR Spectroscopies

Majed Chergui, Thomas James Penfold, Gerald Auböck, Marco Eli Reinhard

Ferrous iron(II) hexacyanide in aqueous solutions is known to undergo photoionization and photoaquation reactions depending on the excitation wavelength. To investigate this wavelength dependence, we implemented ultrafast two-dimensional UV transient absor ...

Iron phosphate nanoparticles for food fortification: Biological effects in rats and human cell lines

Christian Ludwig

Nanotechnology offers new opportunities for providing health benefits in foods. Food fortification with iron phosphate nanoparticles (FePO4 NPs) is a promising new approach to reducing iron deficiency because FePO4 NPs combine high bioavailability with sup ...

Castles fall from inside: Evidence for dominant internal photo-catalytic mechanisms during treatment of Saccharomyces cerevisiae by photo-Fenton at near-neutral pH

César Pulgarin, Sami Rtimi, Stefanos Giannakis, Cristina del Socorro Lonfat

In this work, the antimicrobial effects of the photo-Fenton process on yeast cells were tested (Saccharomyces cerevisiae), an essential eukaryotic unicellular model of living cells. Near-neutral pH was used in all studies, while iron sulfate and iron citra ...

Degradation mechanism of slag blended mortars immersed in sodium sulfate solution

Wei Sun, Karen Scrivener

Additions of slag are usually considered to give cementitious materials which perform well in sulfate bearing environments. This paper compares the deterioration of slag cement blends to those of plain Portland cement and demonstrates that this occurs more ...

Inactivation by solar photo-Fenton in pet bottles of wild enteric bacteria of natural well water: Absence of re-growth after one week of subsequent storage

César Pulgarin, Juliette Ndounla

Iron photo-assisted inactivation of wild enteric bacteria (total coliforms/E. coil and Salmonella spp.) was carried out in water from the Sahelian wells having different pH (W1:4.9 and W2: 6.3) and a natural iron content of 0.07 mg/L We evaluate the effici ...

Investigation of Sulfate Attack by Experimental and Thermodynamic Means

This work investigates sulfate attack in complex sulfate environments by exposing different binder types to various sulfate solutions and comparing predicted phase and volume changes with experimental data. The most important aspects of this work can be gr ...
