The particle size, morphology and magnetic properties of CFO depend on the synthesized method. In this paper, we report the synthesis of CFO NPs by co-precipitation method and hydrothermal method at different concentration of sodium hydroxide and treatment temperatures to control size particles and magnetic properties by simple way.

Three kinds of hierarchical Mordenite Framework Inverted (MFI)-type nanozeolites including Si-MFI, Al-MFI and Ti-MFI were successfully synthesized by two-stage varying temperature hydrothermal treatment. Taking toluene as the probe molecule, a series of methods were used to evaluate the adsorption properties of as-synthesized hierarchical zeolites samples including the adsorption breakthrough curves, simulation of adsorption isotherms as well as kinetics models and toluene-TPD (the temperature programmed desorption of toluene).

Finger millet is an important millet owing to its excellent storage properties and the nutritive value. So dehulling or pearling of finger millet is necessary to remove its outer layer to improve its flour quality. Pearling of this millet is quite difficult as its seed coat is bound tightly to the endosperm of the grain.

Mesoporous carbons containing up to 3.6 at.% N and 4.4 at.% O and exhibiting graphitic character have been prepared from Ni(II) and Fe(II) phthalocyanines by direct pyrolysis or by HTC + pyrolysis, and subsequently applied as supercapacitor materials. No mesoporous templates or doping post-treatments were used, and the catalytic effect of Ni(II) and Fe(II), naturally present in the precursor molecules, allowed obtaining graphitic carbons at temperatures 900 C.

Hydrothermal Carbonization is a thermochemical conversion process in which a biomass is processed under hot compressed air to form carbon rich products called as hydrochar. Hydrochar is a hydrophobic, condensed and friable solid product with a fuel property similar to conventional non-renewable energy sources like coal and lignite.

The results showed that the samples heat-treated at low temperature (≤600 ◦C) exhibited anatase phase and for Cr3+-doped anatase TiO2 samples with x ≥ 0.01, Raman spectra showed a new series of peaks at 120, 236, 250, 292, 362, 430, 467 and 550 cm−1 , which were assigned to the localized vibrational modes related to the complexes containing Cr3+ ions. The samples heat-treated at high temperature (1100 ◦C) exhibited rutile phase. It was observed that the characteristic Raman modes (Eg and M) for rutile TiO2 were shifted and broadened with increasing Cr3+ dopant content.

NiFe2O4 superparamagnetic nanoparticles have been prepared by the method of spraying - co-precipitation subsequent by hydrothermal treatment. This procedure allowed to produce efficiently nanoparticles with high performances. Different techniques such as XRD, TEM, EDX, VSM were used to investigate the morphology, structure and magnetic properties of the obtained materials.
