Patel K. K. Effects of Annealing on Structural Properties of Copper Zinc Tin Sulphide (CZTS) Material [Електронний ресурс] / K. K. Patel, D. V. Shah, V. Kheraj // Journal of Nano- and Electronic Physics. - 2013. - Vol. 5, № 2. - С. 02031-1-02031-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnep_2013_5_2_33 Copper Zinc Tin Sulphide compound was synthesized from its elemetal precursurs using simple solid state method. Being quarternary material, there is a large probability of formation of secondary phases like SnS, ZnS, CuS during the material growth process and it requires a detail investigation on the effects of synthesis parameters on the composition and structural properties of the CZTS compound. Here we report the study of effects of annealing on the synthesized compound. The annealing was performed at two different temperatures in the presence of Sulphur. The structural and compositional properties of the asgrown and annealed samples were examined by X-ray diffraction (XRD) and Energy Dispersive Analysis of X-Ray (EDAX). The formation of Kesterite CZTS phase was confirmed by Raman Spectroscopy.

Shaikh I. A. Investigating the Effect of Sintering Treatment on Structural and Magnetic Properties of Fe3O4 Nanoparticles [Електронний ресурс] / I. A. Shaikh, A. V. Raval, D. V. Shah // Journal of nano- and electronic physics. - 2020. - Vol. 12, no. 2. - С. 02009-1-02009-4. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2020_12_2_12 The magnetite Fe3O4 nanoparticles with a size range of 8 - 9 nm were synthesis by the chemical coprecipitation of ferrous chloride, ferric chloride and NaOH as reducing agent with some modifications in the reported methods. The synthesized magnetic nanoparticles were heated at different temperature in the range of <$E250~symbol Р roman C> to <$E850~symbol Р roman C>. The effect of heating on structural properties of synthesized sample was studied by X-ray diffraction (XRD) and field effect scanning electron microscope (FESEM). The XRD patterns confirm the formation crystalline phase of Fe3O4 nanoparticles. The pattern formation of the nanoparticles was observed upon sintering treatment. Also there was a phase transition from magnetite (Fe2O3) to hematite (<$Ealpha - roman {Fe sub 2 O} sub 3>) was observed when the samples was heated above <$E55~symbol Р roman C>. The vibrating sample magnetometer (VSM) was used to study the magnetic properties, hysteresis curve and the saturation magnetisation. The saturation magnetisation decreases as the annealing temperature increases which is attributed to the phase transformation.

Jain V. M. Surfactant Free Synthesis and Study of Vanadium Pentoxide Nanostructure [Електронний ресурс] / V. M. Jain, D. V. Shah, K. K. Patel, M. S. Shah // Journal of nano- and electronic physics. - 2020. - Vol. 12, no. 2. - С. 02017-1-02017-3. - Режим доступу: http://nbuv.gov.ua/UJRN/jnef_2020_12_2_20 The varied oxidation state and layered structure are two importance features of vanadium pentoxide which makes it more special. Here, vanadium pentoxide nanostructure has been synthesized by a surfactant free and ecofriendly method using ammonium vanadate as a precursor salt. Synthesized nanostructure were characterized using X-ray diffraction method (XRD), Energy Dispersive X-Ray Analysis (EDAX), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and UV-Visible spectroscopy to study its structural, compositional, morphology, vibrational modes and optical behavior. XRD and FTIR confirm the orthorhombic phase of the vanadium pentoxide with a layered structure of irregular plates as observed from the SEM micrograph. Moreover, the band gap of material is 2,13 eV as evaluated from UV-Visible data.
