Jute fabric is well-known reinforcing material in composite science, however, there is a necessity to treat these fabrics to reduce moisture uptake and improve properties.
Introduction In the last three decades we have seen a great research and development in the field of composite materials resulting into application of new materials and material combinations.
Traditional support materials were used and further for better resin flow during production, resin distribution medium and Resinflow mesh were applied.

“Utilization of sludge as brick materials”.

Therefore, SnS can be potentially used as photovoltaic materials.
The same method deposition was used for the preparation of semiconductor materials SnS and SnS2 [31].
SnS combined with some common semiconducting materials (TiO2,CdS,Si) can get the solar cell.
