AB  - Hydrothermal synthesis of Mn2+ doped titanate nanotubes (TNTs), which exhibited room temperature ferromagnetism (RTFM), is reported. Dispersions of 1 and 5 at.% Mn2+ doped anatase TiO2 nanocrystals were used as precursors. Size and shape of Mn2+ doped TNTs and precursor nanocrystals were studied by transmission electron microscopy (TEM). The relatively uniform size distribution of transverse dimension of nanotubes of about 10 nm was observed while their lengths varied up to few hundred nanometers. The X-Ray Diffraction (XRD) analysis and Raman spectroscopy of resultant powder confirmed the hydrogen dititanate (H2Ti2O5 x H2O) crystal phase of Mn2+ doped TNTs with the presence of small amount of sodium titanates. Electron paramagnetic resonance (EPR) experiments were performed to probe the local atomic and electronic structure of Mn in the nanotubes. Room temperature ferromagnetic ordering with saturation magnetic moment (Ms) in the range of 0.6–1.5 μB per Mn atom was observed. © 2019 Elsevier Masson SAS

AB  - Co2+ doped TiO2 nanocrystals were synthetized by a hydrothermal treatment procedure applied to precursor dispersion of titania nanotubes and Co2+ ions. Mixture of polygonal and prolate spheroid-like nanocrystals was obtained. The results of X-ray diffraction (XRD) analysis showed that resulted nanocrystals retain anatase crystal phase for both dopant concentrations (1.69 and 2.5 at%), but the crystal lattice parameters were affected. Reflection spectra revealed altered optical properties compared to bare TiO2. Room temperature ferromagnetic ordering with saturation magnetic moment in the range of 0.001-0.002 mu (B)/Co was observed for both measured films made of Co2+ doped TiO2 nanocrystals.

AB  - Ethylene-co-vinyl acetate/iron nanocomposite films were fabricated by implantation with multiple charged ions at different fluencies. The films obtained with ion fluency of 1 x 10(17) cm(-2) were used for specific studies. It was found that spherical similar to 1.5 nm diameter nanoparticles were formed upon implantation. They were clustered into a single 80 nm wide strip about 40 nm beneath the film surface. The magnetic measurements of the film showed that the particles exhibit superparamagnetic behavior with a blocking temperature below 5K. A second type of the samples was also prepared with ion fluency of 1 x 10(17) cm(-2), but prior to implantation, the iron was evaporated onto the co-polymer surface. A nanocomposite film of different morphology was obtained upon the implantation and the particles were much smaller (-0.8 nm). The magnetic behavior of both the films was that of isolated nanoparticles, despite the high ion fluency of 1 x 10(17) cm(-2). (C) 2016 Elsevier B.V. All rights reserved.

AB  - Cu2+ doped TiO2 nanocrystals were synthesized using dispersions of titania nanotubes in the presence of Cu2+ ions as a precursors. The morphologies of nanotubular titania precursors and resulted Cu2+ doped TiO2 nanocrystals were characterized by TEM. Structural and optical properties were studied by XRPD analysis and UV-vis spectroscopy in reflectance mode, respectively. Their magnetic properties were investigated using SQUID magnetometer. Tetragonal anatase crystalline structure was confirmed in all synthesized samples. Polygonal (d similar to 15 nm) and spheroid like (length, up to 90 nm) Cu2+ doped TiO2 nanocrystals in samples synthesized at different pHs were observed by TEM. Ferromagnetic ordering with almost closed loop (H-c similar to 200 Oe) was detected in all Cu2+ doped TiO2 nanoparticle films. The saturation magnetization values varied depending on the Cu2+ concentration, nanoparticles shape, size and consequently different number of oxygen vacancies. This study revealed possibility to control magnetic ordering by changing the shape/aspect ratio of Cu2+ doped TiO2 nanocrystals. (C) 2015 Elsevier Ltd. All rights reserved.

by the oxidative polymerization of aniline with ammonium peroxydisulfate
(APS), in the presence of colloidal TiO2 nanoparticles and TiO2 nanotubes,
without added acid. The morphological, magnetic and structural properties
of the PANI/TiO2 nanocomposites were studied by SEM microscopy,
SQUID magnetometer and FTIR spectroscopy. The electrical conductivity
of synthesized nanocomposites was ~10-3 Scm-1. The room temperature
ferromagnetic response significantly depends on shape of TiO2

AB  - Hydrothermal synthetic route for synthesis of Ni2+ doped TiO2 nanocrystals showing room temperature ferromagnetism, using dispersion of titania nanotubes in the presence of Ni2+ ions at different pHs as precursors, is reported. Morphologies of tubular precursors and Ni2+ doped TiO2 nanocrystals were characterized by transmission electron microscopy. Titania nanotubes have outer diameter of about 10 nm while the length varies widely even reaching few hundred nanometers. Ni2+ doped TiO2 nanoparticles synthesized at pH 3 have polygonal shape and dimension of about 20 nm. Transmission electron microscopy analysis revealed presence of mixed shapes (polygonal and rod like) in the sample of Ni2+ doped TiO2 nanoparticles synthesized at pH 5. X-ray diffraction analysis of resultant powder and selected area electron diffraction pattern confirmed the anatase crystal phase of Ni2+ doped TiO2 nanoparticles independently of dopant concentrations (0.09, 0.25, 0.86, 1.48 and 1.80 at%), followed by slight changes of their microstructural parameters. Reflection spectra of Ni2+ doped TiO2 nanoparticles revealed their altered optical properties in comparison to undoped TiO2 nanoparticles. Room temperature ferromagnetic ordering with saturation magnetic moment in the range of 10(-3)-5 x 10(-2) mu B per Ni atom was observed for all measured films made of Ni2+ doped TiO2 nanoparticles.

AB  - Nanocomposites consisting of self-assembled polyaniline (PANI) nanostructures and titania nanotubes (TiO2-NT) were synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in an aqueous dispersion of TiO2-NT (outer diameter similar to 10 nm), without added acid. The influence of initial mole ratio of aniline to TiO2 (80, 20, and 5) on the morphology, electrical conductivity, molecular structure, crystallinity, and magnetic properties of synthesized PANI/TiO2 nanocomposites was studied. Transmission electron microscopy, Raman spectroscopy, and X-ray powder diffraction proved that the shape and structure of TiO2-NT in the final nanocomposites were preserved. The shape of PANI nanostructures formed in the nanocomposites was influenced by the initial aniline/TiO2-NT mole ratio. Nanotubes and nanorods are predominant PANI nanostructures in the nanocomposite prepared with the highest aniline/TiO2 mol ratio of 80. The decrease of aniline/TiO2 molar ratio induced more pronounced formation of nanorod network. The electrical conductivity of PANI/TiO2 nanocomposites was in the range (1.3-2.4) x 10(-3) S cm(-1). The nanocomposites exhibit weak ferromagnetic behavior. Approximately order of magnitude lower values of coercive field and remanent magnetization were obtained for nanocomposite samples in comparison to pure PANI.

AB  - We report on a new approach toward synthesis of Sm3+ doped TiO2 and Ni2+ doped
TiO2 nanocrystals by shape transformation of hydrothermally treated titania
nanotubes in the presence of Sm3+ or Ni2+ ions. The percentage ratio of Sm3+ (or
Ni2+) to Ti4+ ions in doped nanocrystals was determined using ICP atomic emission
spectroscopy. The XRD patterns revealed the homogeneous anatase crystal phase
of both 0.4 at% Sm3+ doped TiO2 and 0.12 at% Ni2+ doped TiO2 nanoparticles. An
average size of polyhedral Sm3+ doped TiO2 nanocrystals was between 12 and 14
nm. In the orange-red spectral region, room temperature photoluminescence signals
associated with 4
G5/2 →6
HJ (J = 5/2, 7/2 and 9/2) transitions of Sm3+ was observed
in Sm3+ doped TiO2 nanocrystals. Optically transparent film made of 0.12 at% Ni2+
doped TiO2 nanoparticles showed room temperature ferromagnetic ordering. The
coercive field was found to be HC ~ 80 Oe.

AB  - New approach for synthesis of Co2+ doped TiO2 nanoparticles showing room temperature ferromagnetic behavior, through shape transformation of hydrothermally treated scrolled titania nanotubes in the presence of Co2+ ions is described. The XRD and ICP measurements demonstrated successful incorporation of 0.46 at % Co2+ ions in preserved anatase crystal structure of TiO2 nanoparticles, without presence of Co-oxide Clustering, metallic Co, or Various Co-Ti oxide species. HRTEM measurements revealed that majority of the nanoparticles have polygonal shapes with average dimension of similar to 6-10 nm. Obtained Value of 3.06 eV for band gap energy of Co2+ doped TiO2 nanoparticles explained altered optical properties of TiO2 matrix and indicates narrowing of the electronic properties in respect to the undoped anatase TiO2 nanomaterials. The Co2+ doped TiO2 nanocrystals enabled synthesis of optically transparent film that shows room temperature ferromagnetic ordering with a saturation magnetic moment of 0 25 mu B per Co atom The proposed explanation for room temperature ferromagnetic behavior is based oil the presence of critical amount of oxygen vacancies that mediate interaction between Co2+ spins trapped in the lattice Structure of titania nanoparticles with undercoordinated surface defect sites.
