Phosphorus containing and octyl-terminated silicon nanoparticles (NPs) are generated by a solution reduction route under room temperature conditions for the first time and characterized by TEM, HRTEM, EDX, 1H/13C/31P NMR, EPR, and PL spectroscopy, then annealed to form a thin film with phosphorus doping confirmed by microprobe elemental analyses.

High-quality heteroepitaxial LaNiO3 (LNO) thin films were successfully grown on SrTiO3 (STO) substrates with RF-magnetron sputtering deposition at substrate temperatures in a range 150–650 ◦C. Azimuthal scans around the surface Bragg peak of the film and lattice images from a high-resolution transmission electron microscope (HRTEM) show that a well epitaxial relationship between film and substr...

An insulated nanotube wire is formed by the binary phase of layered tungsten disulphide and carbon nanotubes (shown in the HRTEM image) generated by the sulphidization of tungsten oxide coated multiwalled carbon nanotubes at 900 °C. Thermogravimetric analysis shows that the tungsten disulphide coat acts as an antioxidant.

This work describes a wet-processing route based on spray-freezing and subsequent lyophilization designed to obtain nanostructured ceramic/metal powders. Starting from the ceramic powder and the corresponding metal salt, a water-based suspension is sprayed on liquid nitrogen. The frozen powders are subsequently freeze-dried, calcined and reduced. The material was analyzed using X-ray diffractio...

The structural properties of VO2 thin films, grown on either LSAT or Si substrates by pulsed laser deposition (PLD), are elucidated means transmission electron microscopy (TEM) methods. TEM observations confirmed the successful growth PLD in variable thicknesses, optimizing O2 partial pressure and temperature. films adopt a columnar polycrystalline morphology with narrow columns, up to film thi...
