In this research, the effects of transition metal (Ni) doping to metal-oxide nanoparticles (TiO 2 ) were studied. Various weight ratios (5, 10, 15, and 20%) of Ni-to-TiO 2 nanoparticles were synthesized using the sol-gel technique. These doped nanoparticles were prepared using titanium butoxide and nickel nitrate as precursors and methanol as a solvent. The effects of Ni doping to TiO 2 were examined using a variety of characterization techniques, X-ray diffraction (XRD), Fourier-transform-infrared (FTIR) spectroscopy, ultraviolet-visible (UV-Vis) spectroscopy, field-emission scanning electron microscopy (FESEM), and vibrating sample magnetometer (VSM). The XRD reveals that the Ni-doped TiO 2 crystallizes in a tetragonal structure with anatase phase. The particle size and lattice strain were calculated by Williamson-Hall equation. The presence of strong chemical bonding and functional groups at the interface of TiO 2 nanoparticles was confirmed by FTIR. The optical properties of undoped and doped samples were recorded by UV-Vis spectroscopy. The saturation magnetization (M s ) was found higher for undoped as compared to doped samples. The surface morphology and the element structure of the Ni-doped TiO 2 nanoparticles were examined by FESEM.

“…Thermal characteristics of the SNP@PVA and SNP@PMMA films were illustrated from the simultaneous TGA/DTA analysis ( Figure 6). Thermal analysis of both SNP-polymeric composite films depicted a representative three-stage weight loss profile [23]. The first weight loss The SNP@PVA film showed significantly greater weight loss (96.49%) owing to lower SNP content and hence lesser inorganic residue.…”

In the present work, we report the fabrication of silica nanoparticles embedded polymeric (SiO 2 nanoparticles@polymer) composite films for numerous traits like texture, folding endurance, crystallinity, size, thermal behavior, spectral analysis, and bioactivity. Significant facets of bulky, inert, inorganic materials are known to burgeon out due to the high surface area of nanosized particles. Nature and proportion of silica nanoparticles as well as polymers exhibited remarkable impact on the fabrication and quality of casted films. Hydrophilic silica nanoparticulate-PVA films depicted better mechanical properties like thermal plus photo stability. Hydrophobic silica nanoparticulate-PMMA films showed qualities of a robust, active, thermostable, antimicrobial material that could resist extreme storage and processing conditions. Overall, these metal oxide nanoparticle-polymer composite films possess qualities reflecting their potential in food, pharmaceutical, and cosmetic industry.

Titanium and silica oxides nanoparticles were introduced into hybrid silica sol-gel/epoxy coating to enhance the mechanical properties of coatings. Titanium dioxide (TiO 2 ) and silica oxide (SiO 2 ) were chemically synthesised before adding to the prepared silica sol gel coating. X-ray diffraction (XRD), Energy-dispersive x-ray analysis (EDX) and Transmission Electron microscope (TEM) were used to characterize the prepared nanoparticles. The coating was then applied to 3003 aluminium alloy (AA3003) surface. The adhesion performance of different sol gel coating compositions was investigated using shear test to define the influence of nanoparticles on adhesive strength of the coating. The Rockwell C hardness test was used to study the micro-hardness of different compositions of sol gel coating. Also, contact angel was used to investigate the hydrophobicity of the coatings. The results showed that there was a significant improvement of the adhesion performance of hybrid silica sol gel coating due to addition of TiO 2 and the hydrophobicity of sol gel coating was increased due to addition of SiO 2 nanoparticles.
