In both alloys the eutectic melting peaks at lower temperatures have disappeared which
means that the homogenisation treatment has been successful in removing the eutectic structures.

The heated dilute alkaline solution slowly etches facets in particular crystal orientations as it forms pyramid structures, an etch time of 45min is needed to achieve performance in the range of <12% reflection at 700nm.
Considering the amount of silicon loss, 40μm, the amount of process time, ~1hr, and the exorbitant amount of wet chemistry a simplified approach is desirable.

The crystal phase structure of the cathode is examined using a D8 Advance X-ray diffractometer(XRD).
Based on the twin perspectives of green chemistry and efficiency, the use of molten salts and other similar solvents is inadequate.
Cathode structure analysis Various cathodes were prepared by adding graphite, calcium carbonate, and cellulose, respectively.
Graphite forms a bridging structure conducive to electron transfer that increases conductivity [18, 19].
The structural characteristics of carbon mainly show a sheet structure before electrolysis.

The magnetic
characterization of the structures was done by magnetic force microscopy (MFM) and Mössbauer
spectroscopy.
The magnetic properties of nanowires are dependent on diameter and length of the structures as well as preparation conditions [3].
Ordered, close packed structure of the pores with size of about 40nm are shown in Fig.1a.
These structures were obtained in (COOH)2.
Value of pH influences on quality of the final structures.

The continuous network structure composed of silica aerogels of high purity are non-crystallized, porous, surface areas from 800 to 980 m2/g and light weight nano-materials.
Silica aerogels is a nano-structured material with high specific surface area, high porosity, low density, low dielectric constant and excellent heat insulation properties [3].
Composites of fiber and silica aerogels have been produced as an attempt to fortify the structure.
After the washing, the ethanol trapped inside the pore structure of the wet gel was exchanged with n-hexane to avoid reaction with the surface modification reagent, trimethylchlorosilane (TMCS), later applied to the gel.
Sample weight after absorbing toluene Fig. 5 shows the SEM of aerogels of three-dimensional nano-porous structures for silica aerogels.
