The objective of this research was to extract chitosan from waste Crustacean shrimp shells of the species Penaeus Monodon, which is a by-product of the shrimp export industry. Then the extracted chitosan was used to ...

Hybrid organic-inorganic metal halide based perovskite solar cells (PSCs) lie at the heart of the emerging technologies of the solar cells due to their ability to increase the cell efficiencies dramatically over the last ...

Corrosion is the gradual destruction of material, usually metal, by chemical reaction with its environment. Usually the corrosion rate cannot be measured directly which needs sample preparation, fixing of samples in a ...

This thesis is focused on developing an alternative roofing material for asbestos fibre cement sheets. Coal Fly ash (CFA) was selcted as the main matrix modifier, which was collected from the electrostatic precipitator in ...

Heavy metal pollution is a serious problem to aquatic ecosystems because some of these metals are potentially toxic even at very low concentrations. Chitosan, a biopolymer produced from crustacean shells, has applications ...

In the present study the feasibility of utilization of high alumina roller waste from fast firing kiln was studied. These roller wastes, which contain important quantities of S i 0 2 and Al203, can be used as cheaply ...

This thesis· describes the work that have been carried out to produce different types of cast iron grinding media and liner plates of good wear resistant quality for the local industry. The types ...
