A novel photoelectrochemical aptasensor for adenosine triphosphate (ATP) detection was developed by introducing inorganic−organic photoactive nanocomposites as sensitization agents to achieve significant signal amplification. Specifically, a TiO2/Au hybrid structure was first fabricated by decorating Au nanoparticles on the surface of TiO2 film, which then was used as the photoelectrochemical m...

The objective of the present study is the synthesis of MWCNT-TiO2 hybrid nanostructures by solvothermal synthesis method with TiCl4 as precursor. The heat transfer enhancement due to the use of MWCNT-TiO2 nanofluid was investigated. As-prepared hybrid materials were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that MWCNTs were uniformly dec...

ZnO and ZnO: Mn nanocrystals were synthesized via reverse micelle method. The structural properties of nanocrystals were investigated by XRD. The XRD results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. Resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...
