Vertical changes of the Co and Mn speciation along a lateritic regolith developed on peridotites (New Caledonia)

Gabrielle Dublet, Vincent Noel

Because they can host significant amounts of Co, the Mn-oxides are commonly considered as the major Co-bearing mineral species in lateritic environments. However, little is known about the process leading to the formation and/or the weathering of these Co- ...

Chelating agents as coating molecules for iron oxide nanoparticles

Heinrich Hofmann, Marijana Mionic Ebersold, Josefina Adriana Maria Bastiaansen, 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 ...

Effects of coating spherical iron oxide nanoparticles

Tao Li

We investigate the effect of several coatings applied in biomedical applications to iron oxide nanoparticles on the size, structure and composition of the particles. The four structural techniques employed - TEM, DLS, VSM, SAXS and EXAFS - show no signific ...

Folic acid on iron oxide nanoparticles: platform with high potential for simultaneous targeting, MRI detection and hyperthermia treatment of lymph node metastases of prostate cancer

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

The overexpression of the folate receptor in most cancers has been widely exploited to specifically deliver folic acid (FA) coupled nanomedicines to tumors. However, complex coupling chemistry is often used to bind FA to the nanoparticles. Furthermore, ver ...

Controlling structural and magnetic properties of IONPs by aqueous synthesis for improved hyperthermia

Heinrich Hofmann, Alla Arakcheeva, Débora Bonvin, Marijana Mionic Ebersold

Iron oxide nanoparticles (IONPs) were synthesized by a novel aqueous synthesis route which combines co-precipitation (CP) and hydrothermal (HT) treatment, termed CP + HT, and compared with IONPs obtained by the standard CP method. Properties of both types ...

Versatility of Pyridoxal Phosphate as a Coating of Iron Oxide Nanoparticles

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

Pyridoxal 5'-phosphate (PLP) is the most important cofactor of vitamin B-6-dependent enzymes, which catalyses a wide range of essential body functions (e.g., metabolism) that could be exploited to specifically target highly metabolic cells, such as tumour ...

Hydrothermal growth of iron oxide NPs with a uniform size distribution for magnetically induced hyperthermia: Structural, colloidal and magnetic properties

Heinrich Hofmann, Kurt Schenk, Olivier Jordan

Magnetic iron oxide nanoparticles with a narrow size distribution were synthesized by hydrothermally treating suspensions of iron oxide nanoparticles. Ricinoleic-acid-coated magnetic nanoparticles were co precipitated at room temperature from an aqueous so ...

The electronic, chemical and electrocatalytic processes and intermediates on iron oxide surfaces during photoelectrochemical water splitting

Michael Graetzel, Yelin Hu, Artur Braun, Florent Alexandre Boudoire

We re-assess experimental soft X-ray absorption spectra of the oxygen K-shell which we recorded operando from iron oxide during photoelectrochemical water splitting in KOH electrolyte. In particular, we refer to recently reported transitional electron hole ...

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 ...
