ABSTRACTAccording to a few recent studies, calcium titanate is a material that is similar to hydroxyapatite in biological properties. However, calcium titanate is not currently being used in the biomedical application as to hydroxyapatite. The objective is to prepare nano calcium titanate powder from the solution of calcium oxide, ethanol, and titanium (IV) isopropoxide via sol-gel synthesis. The fiber size, pore size and morphology were studied by phenom scanning electron microscope (SEM). T...
ABSTRACTThe effect of Heat treatment on the Mechanical Properties of a welded joint of medium carbon steel has been carried out. The materials were cut, welded, to get 27 samples needed. Thereafter, Heat Treatment was carried out on the samples. Then the specimens were grouped into two groups, group A and group B. In group A, after the heat treatment on the welded specimens, one sample was quenched in water immediately, another was oil-quenched and the third one was allowed ...
ABSTRACT Attempt was made to produce wood pellets from sawdust using locally sourced binders as an alternative binder, to wood lignin which is a natural binding agent. Wood pellets were produced by manual moulding with starch concentration of cassava and potato starch as the process variable. Results show similar behavior between pellets bonded by cassava, and potato starch, But differs slightly in the case of calorific value and smoke analysis, it shows that smouldering produce the high...
