Investigation of the morphological cell structures and their optical significances of .

The transparent wing of the dragonfly has been investigated using scanning electron microscopy (SEM), optical microscopy (OPM), energy-dispersive X-ray spectroscopy (EDS) and reflectance spectroscopy. Four cells (D1-D4) were studied and classified according to their general morphology. The OPM depicted the vein-joint characterised by the distribution of resilin.

Influence of n-Mosfet transistor on dye-sensitized solar cell efficiency.

A new strategy for evaluating the efficiency of Dye-sensitized Solar Cell (DSC) employed in this study was to introduce a device stabilizer which also functioned as an external load. This aim was accomplished through computations of efficiency of different DSCs based on n-Mosfet transistor. Transistor Z44 mosfet's impact on the DSC systems was to significantly moderate the effect of two vital components namel; the photoanodes and electrolyte sensitizers.

Structural and optical investigation on the wings of (Moore, 1877).

The nanostructures on the wings of (Moore, 1877) were analysed using scanning electron microscopy, energy dispersive X-ray spectroscopy, atomic force microscopy, Fourier transform-infrared spectroscopy, and reflectance measurements. The chemical and morphological analyses revealed the chitin-based intricate nanostructures. The influence of the nanostructures on the wetting characteristics of the wing was investigated using optical imaging.
