SnO2-CuO nanocomposites have been synthesized with the simple co-precipitation method for gas sensing properties. Sn and CuO powder were the starting materials. The synthesized products were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that SnO2-CuO nanocomposites have a tetragonal and monoclinic structure, respectively. SEM images verify that the some microballs are up to 10 µm and nanorods have a diameter range from 10-100 nm, while length ranges a few micrometers. The nanocomposite products were highly sensitivity to CO2gas at room temperature.

In present study, ZnO-SnO2 nanocomposite was synthesized by co-precipitation method and its sensing properties with respect to carbon monoxide gas were investigated. X-ray diffraction pattern shows the exhaustive evolution of hexagonal wurtzite phase of ZnO and rutile phase of SnO2. Morphological study was done by FE-SEM and optical characterization was done by UV-visible spectrophotometer. To study the sensing properties, material was layered on conducting substrate and resistance was recorded in the presence of air and CO gas at different operating temperature. Sensing responses of pure ZnO and ZnO-SnO2 composite was also compared. ZnO-SnO2 showed much enhanced response along with better response and recovery time compared to pure ZnO.

The aim of this work is to investigate the strain sensing properties of polyester/magnetite composite materials of different contents 5, 10, 15, 20% w/w. Specifically, we manufactured magnetic composite materials with a polyester matrix (thermosetting polymer) and nanoparticles of magnetite (Fe3O4) as additives, processed by molding technique. For these composites we used two different magnetite powders of grain sizes a) 20-30nm (premade from Alfa Aesar) and b) <1 μm (powder made by the co-precipitation method in our laboratory). The specimens were subjected into tensile stress in order to observe the alternation of Reluctance induced by strain. The sensing probe is consisted of an electromagnet and a Hall sensor (magnetic flux density sensor). The electromagnets coil is supplied by direct current (DC) causing magnetic flux to circulate the core of the specimen. The results from the tensile stress experiments show that the magnetic flux density B decreases analogous to the Strain.
