  Abstract
  The material has been successfully prepared by the most convenient solid stare reaction route method. The material has been structurally analyzed using X-ray Diffraction (XRD). The sample has been found to be crystalline, single phase with particle size of the order of 80nm. The sample was found to exhibit the orthorhombic structure with the space group Pnma. The so obtained XRD pattern was Retvield refined which confirmed the purity, single phase and orthorhombic structure. The dielectric measurements have been carried out which indicated that the as prepared sample is a good dielectric material. The loss is low. The dielectric constant decreases initially at low frequency and attains a minimum value which later at higher frequency tends to increase again. The loss initially is found to increase and after attaining a peak value, it decreases smoothly and tends to obtain a lower value of dielectric loss but shows a sign of increase at higher frequency.

  Abstract
  with the rapid development in semiconductor industries and increasing demand of superior performance for devices, the ability to precisely modulate material interfaces is playing an increasingly dominant part in development of new technologies relevant to our lives. The composite materials showed improved performance of solar cells, and sensors which require high sensitivity are demanded by the surface characteristics of the materials. Therefore, controlling the structures of material surface and fabricating surfaces with composite materials are extremely important. In the present work, Nano Zinc Oxide (ZnO) thin film was prepared using chemical bath deposition on glass substrate. Polyaniline (PAni) thin film was prepared using chemical oxidative method at room temperature. Using the same technique Nano ZnO-PAni thin film composite was prepared. The prepared sample was characterized using FTIR, XRD, UV-visible spectrometer and SEM. Formation of ZnO thin film was confirmed by XRD and FTIR analysis, also crystalline form of polyaniline was confirmed by UV analysis. Increased in the absorbance of Pani-ZnO composite indicate the interaction between them.

  Abstract
  The present study outlines a procedure to evaluate flutter characteristics of a Bisplinghoff Ashley and Halfman (BAH) wing. The flexibility matrix has been derived using bending, torsion and shear stiffness distribution along the span of the wing. The procedural aspect of deriving the dynamically coupled energy equivalent mass matrix is outlined. The aerodynamic matrix used can be derived using the doublet methods. Nastran package has been used to develop the aerodynamic influence coefficient matrices using the doublet in strips. The final flutter analysis has been computed to verify the procedural aspects of the calculations.
