To prepare a novel Bio sensor for ethanol vapour detection with higher sensitivity. In this Zn(Mn)/ZnO inverted core shell structure is doped in starch. Add a noble metal foe the better response. After this making thin films and determine the thickness of a thin films. Dielectric constant is determined by using the LCR meter. The characterization is done by using XRD, SEM, and the sensing properties of ethanol sensor are based on the resistance-based sensing

The Y-type hexaferrites Sr2CO2-XBixFe12O22 (x=0.0, 0.05 and 0.10) has been synthesized using Sol Gel technique. The structural and magnetic outcome of Bismuth dopant was investigated by XRD, FTIR and VSM study. The XRD reveal the formation of Y-type hexaferrite. Two prominent peaks were observed near 400-600 cm-1 in FTIR spectra indicates twisting and broadening of Fe-O bond at octahedral and tetrahedral sites, respectively. The squareness ratio (Mr/ Ms) of less than 0.5 for all compositions reveals that nanoparticles are haphazardly oriented multi domain particles.

This review reports the major characteristics associated with titanium–dioxide nanoparticles for different methodology. Titanium dioxide has drawn attention worldwide for large scale manufacturing due to its properties along with nontoxic behavior for various applications. Titanium dioxide is considered as suitable for materials for pollution degradation and helps to promote the rate of photosynthesis. Structural properties were discussed with help of X-ray diffraction that helps to investigate physical characteristics. The estimated crystallite size found to be increase with increase in temperature. Morphological analysis was done with the help of scanning electron microscopy and transmission electron microscopy. The morphological behavior shows the formation of homogeneous spherical nanoparticles and agglomeration obtained for sample calcinated at higher temperature.
