UNLABELLED TeO2-nanostructured sensors are seldom reported compared to other metal oxide semiconductor materials such as ZnO, In2O3, TiO2, Ga2O3, etc. TeO2/CuO core-shell nanorods were fabricated by thermal evaporation of Te powder followed by sputter deposition of CuO. Scanning electron microscopy and X-ray diffraction showed that each nanorod consisted of a single crystal TeO2 core and a poly...

MWCNTs/TiO2 nanocomposite was prepared by oxidising MWCNT in H2SO4/HNO3 then decorating it with TiO2-p25 nanopowder. The composites were characterised using XRD, TEM, FT-IR PL and UV-vis spectroscopy. The TEM images have shown TiO2 nanoparticles immobilised onto the sidewalls of the MWCNTs. The UV-vis spectrum confirms that the nanocomposites can significantly absorb more light in the visible r...

This study reports the simple process to synthesis of CuO/CuI nanocomposite in a non-aqueous solution. In the conducted experiments CuI and Dimethyl Sulfoxide (DMSO) were used as the precursors. Moreover, DMSO had role of solvent and ligand simultaneously. In experiments the effects of oleic acid as the particles size modifier, temperature and concentration were investigated. Crystalline struct...

In order to improve the photocatalytic activity of TiO2, we successfully loaded nano-CuO on TiO2 nanomeshes as CuO-TiO2 nanocomposites through a facile electrodeposition method. The optimized calcined temperature after Cu is confirmed 450 °C, which could furthest assist crystallization anatase and guarantee high nanocomposites. Comparing with pure nanomeshes, showed better degradability methyle...

Polypropylene (PP) meltblown fibers were coated with titanium dioxide (TiO2) nanoparticles using layer-by-layer (LbL) deposition technique. The fibers were first modified with 3 layers of poly(4-styrenesulfonic acid) (PSS) and poly(diallyl-dimethylammonium chloride) (PDADMAC) to improve the anchoring of the TiO2 nanoparticle clusters. PDADMAC, which is positively charged, was then used as count...

In the present study, biogenic synthesis of a CuO/rGO nanocomposite was carried out successfully using Terminalia arjuna bark extract.

In this study, the effects of treatment with Ag, Au, Cu, Pd, CeO2, CuO, TiO2 and ZnO nanoparticles (NPs) on plant secondary metabolism were tested using an untargeted metabolomic approach in cell suspension cultures Hypericum perforatum L. Variations accumulation metabolites observed after exposure to NPs. Overall, number compounds increased by metal NPs was higher than that oxides. Among oxide...

One of the most important applications of carbon nanotubes (CNTs) is as reinforcement of metal matrix composites, because of their excellent mechanical properties. In this study, Al-TiO2-multi walled carbon nanotubes (MWCNTs) nanocomposite is fabricated using isostatic pressing followed by hot extrusion. Mechanical alloying is used to mix powders of aluminium, TiO2 and MWCNTs. TiO2 with the amo...

Nanocomposite polymer electrolyte membranes (NCPEMs) based on poly(acrylic acid)(PAA) and titania (TiO2) are prepared by a solution casting technique. The ionic conductivity of NCPEMs increases with the weight ratio of TiO2.The highest ionic conductivity of (8.36 ̆ 0.01) ˆ 10 ́4 S ̈ cm ́1 is obtained with addition of 6 wt % of TiO2 at ambient temperature. The complexation between PAA, LiTFSI and T...

A unique nanocomposite C-TiO2 was prepared by the growth of TiO2 on carbon nanoparticles using a simple hydrothermal procedure. Transmission electron microscopic (TEM) measurements showed that the nanocomposites exhibited an average core diameter of approximately 5 nm with a rather well-defined lattice space (0.4 nm) that was somewhat larger than that (0.38 nm) of the (100) crystalline planes o...
