Immobilized TiO2 nanotube arrays (NTAs) co-modified with Pt and CdS nanoparticles were fabricated by using the combination of photoreduction and chemical bath deposition methods. XRD, SEM, TEM, XPS, UV-Vis and EDX methods were employed to characterize the microstructure and composition of samples, and the results showed that CdS and Pt NPs were uniformly deposited on the surface of TiO2 nanotub...

Highly crystalline titanium dioxide nanoparticles (TiO2-NPs) are synthesized via a simple hydrothermal technique. After structural and compositional analysis, the as-synthesized unmodified TiO2-NPs tested for improvement in two modes of kilovoltage radiation therapy single-photon emission computed tomography (SPECT)/computed (CT). Our results show that provide an observable enhancement CT scan ...

Increasing interests have been paid to nanofluids because of the intriguing heat transfer enhancement performances presented by this kind of promising heat transfer media. We produced a series of nanofluids and measured their thermal conductivities. In this article, we discussed the measurements and the enhancements of the thermal conductivity of a variety of nanofluids. The base fluids used in...

The photocatalytic activity of titanium dioxide (TiO2) was improved by forming a matrix containing silver (Ag) nanoparticles (NPs) prepared plasma process. plasma-assisted reduction process successfully formed metallic Ag on the surface TiO2 NP to create Ag-TiO2 Janus heterostructure. synthesized NPs were characterized using Brunauer, Emmett, and Teller analysis, transmission electron microscop...

Modified cellulose acetate (CA) membranes were prepared by dissolving the polymers in a mixture of acetone (AC) and N, N dimethylacetamide (DMAc) (70:30) solvent and deionized (DI) water was used in the coagulation bath. The introduction of polyethylene glycol (PEG) additive and TiO2 nanoparticles (NPs) into the casting solution has changed the structures of the resulting membranes during the p...
