Although nitro-1,2,5-oxadiazoles (nitrofurazans) possess excellent energetic properties such as a favorable oxygen balance and high heat of formation, their use as plasticizers has received little attention in the scientific literature. Four nitrofurazanyl ethers were synthesized by substitution of dinitrofurazan with linear alkoxides. The synthesized compounds were extensively analyzed by Fourier-transform infrared (FT-IR) spectroscopy, Raman spectroscopy, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), electrospray ionization (ESI) mass spectroscopy, mechanical sensitivity test, <small>¹</small>H nuclear magnetic resonance (NMR) spectroscopy and <small>¹³</small>C NMR spectroscopy. They have lower mechanical sensitivity (&gt;40 J) compared to modern energetic plasticizers in use, including 2,2-dinitropropyl formal/acetal (BDNPA/F), <em>n</em>-butylnitratoethylnitramine (BuNENA), and dinitrodiazaalkane (DNDA-57). In addition, the most promising compound 3-(2-(2-(2-azidoethoxy)ethoxy)ethoxy)-4-nitro-1,2,5-oxadiazole (NFPEG3N3) exhibits competitive thermal properties, with a lower glass transition temperature of −72 °C compared to BNDPA/F (−67 °C) and a higher thermal decomposition temperature of 179 °C compared to BuNENA (173 °C). The enthalpy of formation and heat of explosion of NFPEG3N3 were calculated to be −41.7 kJ mol<small>⁻¹</small> and 3421 J g<small>⁻¹</small>, respectively. The impact of NFPEG3N3 on the glass transition temperature, viscosity and decomposition of the energetic binder glycidyl azide polymer (GAP)-diol was investigated and showed a remarkable decrease in viscosity (45.4%) and glass transition temperature (−3.3 °C) when compared to benchmark plasticizers in 10 wt% mixtures.

Tuning the magnetic anisotropy of soft zinc ferrite nanoparticles was achieved in this work <em>via</em> doping of ferromagnetic cobalt ions for controlled hyperthermia therapy. We synthesized four nanocrystalline zinc ferrites doped with cobalt ions of varying concentrations [Co<small>_<em>x</em></small>Zn<small>_{1−<em>x</em>}</small>Fe<small>₂</small>O<small>₄</small> (<em>x</em> = 0.00, 0.10, 0.30, and 0.50)] using the standard chemical co-precipitation method. The role of doping Co<small>²⁺</small> ions in modifying the physical properties, including microstructural, electronic, optical and magnetic characteristics, of pure zinc ferrite nanoparticles was thoroughly investigated using several characterization techniques. The obtained TEM images verified good homogeneity in both the size and shape of the studied nanocrystalline ferrites. The optical indirect bandgap was estimated to be 1.55 ± 0.03 eV for the nanosized ferrites. Substitution of ferromagnetic cobalt ions in appropriate amounts improved the magnetic responses of the doped zinc ferrite nanoparticles, and thereby, several magnetic parameters such as coercivity, magnetic anisotropy and magnetization were observed to increase gradually.
