The objective of this work is to study the effect of two key factors external magnetic field and applied current density during template-based electrodeposition of nickel nanowires using an electrode distance of 20 mm. Morphology, length, crystallite size and crystallographic characterization of the grown nickel nanowires at an electrode distance of 20mm are presented. For this electrode distan...

The structural evolution of nanocrystalline TiO2 was studied by X-ray diffraction (XRD) and the Rietveld refinement method (RRM). TiO2 powders were prepared by the sol-gel technique. Post annealing of as-synthesized powders in the temperature range from 500 degrees C to 800 degrees C under air and argon atmospheres led to the formation of TiO2 nanoparticles with mean crystallite size in the ran...

The objective of this work is to utilize a low-grade synthetic rutile to produce high-grade titania nanoparticles. Due to the nature of the precursor, the hydrothermal method needs modification in order to accommodate the precursors and chemical reagents. The product will be characterized with the XRD (crystallite size and crystallinity), EDXRF (chemical composition), SEM (Morphology), N2 adsor...

Mechanical alloying of Ti-Si and NiTi was performed by high-energy ball milling at ambient temperature. The structural and compositional evolutions during mechanical alloying were investigated. Results showed that the crystallite size of mechanically alloyed Ti-Si and Ni-Ti powders decreased with increasing milling time and the steady-state crystallite size was approximately 10 nm. The mechanic...

In this paper, we have reported convenient way to access CdTe nanorods by solvothermal decomposition using single source molecular precursor cadmium (II) bis-(isopropyl telluro) propane (SSMP) and quinoline as solvent at relatively low temperature (200oC).As synthesized nanomaterials are structurally characterized by XRD, SEM and UVVisible spectroscopy. SEM micrographs revealed formation of rod...

Crystallization represents the prime example of a disorder-order transition. In realistic situations, however, container walls and impurities are frequently present and hence crystallization is heterogeneously seeded. Rarely the seeds are perfectly compatible with the thermodynamically favoured crystal structure and thus induce elastic distortions, which impede further crystal growth. Here we u...

Four different ceria supported catalyst were prepared by impregnation method with Pt(NO3)2 solution. The two supports are commercially available (MaTeck) and the other two were prepared by precipitation and microwave assisted hydrothermal method (MAH) respectively. The phase composition and average crystallite size of the catalysts were characterised with XRD technique. Finally the catalytic ac...

Hydrotalcites are quite prevalent in nature and their importance is growing more and more because of their very wide range of potential applications and uses. Because hydrotalcite does not exist in significant quantities in nature, coprecipitation methods are the most used for prepartion of hydrotalcite. In this study: Two types of Nano hydrotalcite compounds containing one divalent (Mg-Al) and...
