Rapid, Selective Heavy Metal Removal from Water by a Metal-Organic Framework/Polydopamine Composite

Emad Oveisi, Wendy Lee Queen, Seyedmohamad Moosavi, Daniel Teav Sun, Li Peng, Davide Tiana

Drinking water contamination with heavy metals, particularly lead, is a persistent problem worldwide with grave public health consequences. Existing purification methods often cannot address this problem quickly and economically. Here we report a cheap, wa ...

Hydrogen storage in the carbon dioxide/formic acid system, using homogeneous iron(II)-phosphine catalysts in aqueous solution

Mickael Montandon-Clerc

The valorization of carbon dioxide and its transformation into useful chemicals is essential as mankind consumes more and more fossil fuels, thus producing equivalent wastes. The storage of hydrogen, a promising energy carrier, is also of great interest in ...

Modulation of the endogenous production of protoporphyrin IX in a yeast - based model organism

Georges Wagnières, Jaroslava Joniová, Emmanuel Louis Arthur Gerelli

The main aim of this study was to assess conditions at which simple yeast-based model organism produces maximal levels of protoporphyrin IX (PpIX) after an exogenous administration of its precursor, 5-aminolevulinic acid (ALA), and the ferrous-ion chelator ...

Recent Advances in the Synthesis and Applications of Multimodal Gold-Iron Nanoparticles

Francesco Stellacci

Bimetallic particles based on gold and iron have been gathering increasing interest in biomedical applications because of the synergic combination of the plasmonic features of the inert gold component with the magnetic properties of the iron or iron oxide ...

Chelating agents as coating molecules for iron oxide nanoparticles

Heinrich Hofmann, Josefina Adriana Maria Bastiaansen, Marijana Mionic Ebersold, Débora Bonvin

Due to their high chemical affinity towards metal ions, chelating agents (CAs) have been used for decades for water purification, but also for protection against metal intoxication and in nanomedicine as linking molecules at the surface of nanoparticles. H ...

Understanding Digestive Ripening of Ligand-Stabilized, Charged Metal Nanoparticles

Hubert Girault, Pekka Eero Peljo

Most syntheses of thiolate-protected metal nanoparticles (NPs) include a thermochemical step in which the as-prepared, polydisperse NPs are transformed to a narrower size distribution in a poorly understood process known as digestive ripening (DR). Previou ...

Investigation of Key Parameters Affecting Ion-Capturing Abilities of Mixed-Ligand Protected Gold Nanoparticles

Elif Ertem Bekdemir

Over the past decades, there has been a dramatic change in the types and amounts of metal ions in the biosphere, since we have introduced huge amount of metal waste into our environment in the course of industrialization of our society. Most of the metal c ...

Bacterial inactivation with iron citrate complex: A new source of dissolved iron in solar photo-Fenton process at near-neutral and alkaline pH

César Pulgarin, Andrzej Sienkiewicz, Cristina del Socorro Lonfat

This study reports the first application of Fe-citrate-based photo-Fenton chemistry for the inactivation of Escherichia coil. Promising results of bacterial inactivation at near-neutral and alkaline pH conditions were obtained, while using low iron concent ...

Quantitative aqueous phase formic acid dehydrogenation using iron(II) based catalysts

Gabor Laurenczy, Andrew Francis Dalebrook, Mickael Montandon-Clerc

We present here the results of our investigation on aqueous phase formic acid (FA) dehydrogenation using non-noble metal based pre-catalysts. This required the synthesis of m-trisulfonated-tris[2-(diphe nylphosphino)ethyl]phosphine sodium salt (PP3TS) as a ...
