Evidence of symmetry breaking in a Gd di-nuclear molecular polymer.

A chiral 3D coordination compound, [Gd(L)(ox)(HO)], arranged around a dinuclear Gd unit has been characterized by X-ray photoemission and X-ray absorption measurements in the context of density functional theory studies. Core level photoemission of the Gd 5p multiplet splittings indicates that spin orbit coupling dominates over j-J coupling evident in the 5p core level spectra of Gd metal. Indications of spin-orbit coupling are consistent with the absence of inversion symmetry due to the ligand field.

Exploring the Diversity of Biofilm Formation by the Food Spoiler .

is considered as a major spoiler of meat and seafood products. This study explores the biofilm formation ability and the biofilm structural diversity of 30 multi-origin strains using a set of complementary biofilm assays (biofilm ring test, crystal violet staining, and confocal laser scanning microscopy). Two major groups corresponding to low and high biofilm producers were identified.

Magnetic and luminescent coordination networks based on imidazolium salts and lanthanides for sensitive ratiometric thermometry.

The synthesis and characterization of six new lanthanide networks [Ln(L)(ox)(HO)] with Ln = Eu, Gd, Tb, Dy, Ho and Yb is reported. They were synthesized by solvo-ionothermal reaction of lanthanide nitrate Ln(NO)·HO with the 1,3-bis(carboxymethyl)imidazolium [HL] ligand and oxalic acid (Hox) in a water/ethanol solution. The crystal structure of these compounds has been solved on single crystals and the magnetic and luminescent properties have been investigated relying on intrinsic properties of the lanthanide ions.

Microwave-assisted functionalization of the Aurivillius phase BiSrTaO: diol grafting and amine insertion alcohol grafting.

Microwave-assisted functionalization of the layered Aurivillius phase BiSrTaO by alcohols is thoroughly investigated. The grafting of linear aliphatic and bulky alcohols is studied as a function of the starting material, underlining the importance of the prefunctionalization of the layered perovskite, for instance by butylamine. In addition, the functionalization by α,ω-alkanediols is explored.
