A combination of ring-opening polymerization (ROP) and coordination chemistry methodology has been expanded for the synthesis of a multifunctional, biocompatible, magnetic, luminescent nanohybrid complex comprising magnetite (Fe3O4) nanoparticles (MNPs), poly(ε-caprolactone) (PCL) and europium ions (Eu3+). The structural and morphological characteristic of the nanohybrid intricate were studied by appropriate spectrum and physical researches. The superparamagnetic behaviour and unique Eu3+ fluorescence properties with a high emission intensity of MNP-PCL-Eu3+ were investigated via measurements with a superconducting quantum interference equipment magnetism and fluorescence spectroscopy.

The heat-resistance of coating from deposited steel 15N8G6M3FTB at temperature of 900 °С is studied. It is established that this dependence occurs in the first hours. The average mass gain of the metal scale of such coating at 900 °С is 0.0128 kg/(m2 •h). It is shown that the basis of metal scale of the composition 15N8G6M3FTB is hematite Fe2O3 and magnetite Fe3O4, as well as MnO, which have protective properties. The number of other phase compounds with high protective properties is negligible. The coating from steel 15N8G6M3FTB can be used for applying to the surface of parts operating at elevated temperatures.
