Iron phosphate mediated magnetite synthesis: a bioinspired approach

Giulia Mirabello

The biomineralization of intracellular magnetite in magnetotactic bacteria (MTB) is an area of active investigation. Previous work has provided evidence that magnetite biomineralization begins with the formation of an amorphous phosphate-rich ferric hydrox ...

The chemical evolution of the dwarf spheroidal galaxy Sextans

Pascale Jablonka, Pierre North, Carmela Lardo, Romain Ely Roland Lucchesi, Romaine Theler

We present our analysis of the FLAMES dataset targeting the central 25 ' region of the Sextans dwarf spheroidal galaxy (dSph). This dataset is the third major part of the high-resolution spectroscopic section of the ESO large program 171.B-0588(A) obtained ...

The Pristine survey - X. A large population of low-metallicity stars permeates the Galactic disc

Pascale Jablonka, Pierre North, Nicolas Lawrence Etienne Longeard, Romain Ely Roland Lucchesi

The orbits of the least chemically enriched stars open a window on the formation of our Galaxy when it was still in its infancy. The common picture is that these low-metallicity stars are distributed as an isotropic, pressure-supported component since thes ...

Non-Precious Electrodes for Practical Alkaline Water Electrolysis

Hubert Girault, Alberto Battistel, Alejandro Nicolás Colli

Water electrolysis is a promising approach to hydrogen production from renewable energy sources. Alkaline water electrolyzers allow using non-noble and low-cost materials. An analysis of common assumptions and experimental conditions (low concentrations, l ...

VLT/FLAMES high-resolution chemical abundances in Sculptor: a textbook dwarf spheroidal galaxy

Pascale Jablonka

We present detailed chemical abundances for 99 red-giant branch stars in the centre of the Sculptor dwarf spheroidal galaxy, which have been obtained from high-resolution VLT/FLAMES spectroscopy. The abundances of Li, Na, alpha-elements (O, Mg, Si, Ca Ti), ...

Tailoring thermal properties of functional materials

Xavier François Mettan

Thermal conductivity (k) plays an essential role in functional devices. In some cases, high value is required to transfer heat efficiently. In others, low k assists in maintaining a temperature gradient necessary for device operation. It is profitable to d ...

The last stages of star formation in the dwarf spheroidal galaxy Sextans

Romaine Theler

This thesis is anchored in the research of better understanding of the chemical evolution of galaxies. Many dwarf spheroidal galaxies (dSph) are orbiting the Milky Way displaying various star formation histories. The formation of these dwarf galaxies and t ...

Organometallics versus P4 Complexes of Group 11 Cations: Periodic Trends and Relativistic Effects in the Involvement of (n-1)d, ns, and np Orbitals in Metal-Ligand Interactions

Hui-Chung Tai

The nature of the bonding in ethylene and h2-P4 complexes, M(C2H4)2+ and M(h2-P4)2+, of group 11 metal cations (M = Cu, Ag, Au) has been explored by d. functional calcns. On the basis of the evaluation of symmetry orbitals, the contributions from the inter ...
