Nanomaterials Based on Collaboration with Multiple Partners: ZnNbO Doped with Eu and/or Amino Substituted Porphyrin Incorporated in Silica Matrices for the Discoloration of Methyl Red.

Designing appropriate materials destined for the removal of dyes from waste waters represents a great challenge for achieving a sustainable society. Three partnerships were set up to obtain novel adsorbents with tailored optoelectronic properties using silica matrices, ZnNbO oxide doped with Eu, and a symmetrical amino-substituted porphyrin. The pseudo-binary oxide with the formula ZnNbO was obtained by the solid-state method.

Controlled Synthesis and Characterization of Micrometric Single Crystalline Magnetite With Superparamagnetic Behavior and Cytocompatibility/Cytotoxicity Assessments.

A new class of magnetite (FeO) particles, coined as "Single Crystalline Micrometric Iron Oxide Particles" (SCMIOPs), were obtained by hydrothermal synthesis. Both the single FeO phase content and the particle sizes range, from 1 µm to 30 µm, can be controlled by synthesis. The notable finding states that these particles exhibit vanishing remanent magnetization (σr=0.
