TL;DR: In this paper, the influence of different organic modifiers on structure and optical properties of Fe 3 O 4 nanoparticles has been studied in detail using X-ray diffraction method, transmission electron microscopy, Fourier transform infrared spectroscopy and UV-visible spectrograms.

TL;DR: Calculated electron mobility increases with temperature, which is related to the decreasing value of hopping energy for the tunneling of small polarons, and it has been confirmed that conductivity dispersion is closely related to both the long-range mobility and the short-range Mobility.

TL;DR: The dielectric spectroscopy confirms, that the electrical conductivity and polarization processes are associated with the mobility of electrons in the structure of ferrite and the both, high frequency complex dielectrics permittivity as well as complex magnetic permeability are strongly temperature and frequency dependent.

TL;DR: The results obtained from SEM, TEM and FTIR analyses indicate that both acid treatment and composite formation have no effect on the tubular structure and morphology of halloysite, but modification of theHalloysite nanotubes did influence the drug release rate.

TL;DR: In this article, the influence of reduction by hydrogen in statu nascendi and modification by hydrogen peroxide on the structure and electrical conductivity of electrochemically exfoliated graphite was investigated.
