Sn-TiO 2 nanocomposite coatings were prepared by sol-gel enhanced electrodeposition technique and the effect of c concentration on performance composite was investigated adding different volumes TiO sol to electrolyte. The microscopic morphology corrosion resistance characterized XRD tests, SEM hardness tests a series electrochemical tests. From test results, it found that coating had highest v...

LiV3O8-polyaniline nanocomposites have been synthesized via chemical oxidative polymerization directed by the anionic surfactant sodium dodecyl benzene sulfate. The polyaniline particles are uniformly coated on the LiV3O8 nanorods. The composite with 12 wt. % polyaniline retains a discharge capacity of 204 mAh g after 100 cycles and had better rate capability (175 mAh g at 2 C and 145 mAh g at ...

The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS coating system employing 80:20 Cr:B targets. To vary the composition, the nitrogen fraction was adjusted (N2 fraction = N2/(Ar + N2)) and a moderate bias voltage of –20 V was...

Silver nanoparticles are well-established antibacterial agents. However, an effective design and formulation that ensures: (i) ease of synthesis and fabrication, (ii) amenability to deployment over large surfaces of variable shape, (iii) high efficacy and (iv) multiple reuses with the possibility of periodic monitoring, is yet to emerge. A nanocomposite thin film of poly(vinyl alcohol) with sil...

To enhance the mechanical properties in Ni-alumina nanocomposite coatings, it is necessary to increase the amount of alumina nanoparticles participation in nickel matrix. The aim of this study is the compassion investigation of Ni-Al2O3 nanocomposite coatings’ embedded nanoparticles affected by methanol addition to the electrolyte. In this investigation the composition of electrolyte was modifi...

Objective(s): This paper describes coating of magnetite nanoparticles (MNPs) with amorphous silica shells.   Materials and Methods: First, magnetite (Fe3O4) NPs were synthesized by co-precipitation method and then treated with stabilizer molecule of trisodium citrate to enhance their dispersibility. Afterwards, coating with silica was carried out via a sol-gel approach in which the electrostati...

We used a sol–gel spin coating technique to synthesize nanocomposite thin films based on zinc oxide (ZnO) loaded with silver nanoparticles (NPs). tested these ZnO/Ag NPs photocatalysts, thickness of about 100 nm, for the photodegradation indigo carmine dye solution. The study focused effects Ag ZnO matrix as well impact their concentration photocatalytic performance nanocomposite. also highligh...
