Formation and crystallization of TiO nanostructures on various surfaces.

A comparative study of the synthesis of TiO nanorods on fluorine-doped tin oxide (FTO) glass, Si, SiO, Si/Ta, Si/TiN, Si/TiN/Ti and Si/HFO substrates by hydrothermal reaction is presented. Detailed analysis on the growth of TiO on pre-annealed Si/TiN/Ti and HfO (HFO) surfaces is also given. For Si/TiN/Ti, a pre-annealing procedure led to the transformation of Ti to a TiO layer which acts as a seed for aligned growth of TiO nanorods.

Photoinduced Fabrication of Zinc Oxide Nanoparticles: Transformation of Morphological and Biological Response on Light Irradiance.

The photoinduced synthesis of zinc oxide nanoparticles (ZnO NPs) was carried out to unveil the effects of change in wavelength of photons. ZnO NPs were synthesized by the coprecipitation technique exposed to different light regimes [dark environment, daylight, and blue-, green-, yellow-, and red-colored light-emitting diodes (LEDs)] at room temperature. X-ray diffractogram (XRD) revealed the wurtzite structure of ZnO NPs.

Relaxation dynamics and polydispersivity associated with defects and ferroelectric correlations in Ba-doped EuTiO.

We present the frequency- and temperature-dependent dielectric response of Eu Ba TiO (0  ⩽  x  ⩽  0.5) in detail. Excluding grain boundary effects, four relaxation mechanisms were observed.
