“Fe-x(CoNi)(1-x) (x = 0.14, 0.20, 0.25) ternary alloy nanoparticles were fabricated by a self-catalyzed reduction method at a low temperature. The investigation of static magnetic properties revealed both saturation magnetization and coercive force enhanced with increasing Fe content. By dispersing alloy nanoparticles into paraffin matrix homogeneously, the electromagnetic properties of them were investigated ACY-738 Epigenetics inhibitor experimentally and the electromagnetic

absorption performances were calculated according to transmission line theory. Significant dielectric relaxation was found in the low Fe content sample, which is dominant in dielectric loss. The magnetic loss was attributed to natural resonance and the resonance peaks’ shift to high frequency region with increasing Fe content. The enhanced electromagnetic absorption performances were obtained by adjusting Fe content to balance selleckchem electromagnetic parameters, because the electromagnetic parameters can be varied by structural and magnetic properties.

“Complex mixtures of contaminants with potential adverse effects on human health and wildlife are found in the environment and in the food chain. These mixtures include numerous anthropogenic compounds

of various origins and structures, which may behave as endocrine disruptors. Mixture’s complexity is further enhanced by biotic and abiotic transformations. It is therefore necessary to develop new strategies allowing the identification of the structure of known, as well as unknown, nuclear receptor (NR) ligands present in complex matrices. We explored the possibility to use NR-based affinity

columns to characterize the presence of bioactive molecules in environmental complex mixtures. Estrogen receptor alpha (ER alpha)-based affinity columns were used to trap and purify estrogenic substances present in surface sediment samples collected in AP26113 research buy a French river under mixed anthropogenic pressure. We combined biological, biochemical and analytical approaches to characterize the structure of ligands retained on columns and demonstrate the presence of known active molecules such as bisphenol A and octylphenol, but also of unexpected ER alpha ligands (n-butylparaben, hydroxyl-methyl-benzofuranone). High resolution mass spectrometry results demonstrate that ER alpha affinity columns can be used for the isolation, purification and identification of known as well as unknown estrogenic contaminants present in complex matrices.”
