    Abstract: Transesterification is a widely used chemical reaction in chemical industry. The use of common homogeneous catalysts that comprise of alkali metal hydroxides/alkoxides and inorganic acids lead to intricacies associated with post reaction separation of catalysts from products. On the other hand, heterogeneous catalysts possess the drawback of limiti... Show More

    Abstract: The three-body abrasive wear of Titanium Carbide (TiC) filled and unfilled E-glass-epoxy (G-E) was experimentally investigated using rubber wheel abrasion tester (RWAT). The composites were fabricated by using vacuum assisted resin transfer molding (VARTM) with 0-6 wt % of TiC in steps of 2 wt %. The mechanical properties of the TiC filled and unfi... Show More

    Abstract: The computer controlled multistage synthesis of fine-grained photographic emulsions is described. Scanning electron microscopy was used to investigate the shape and size (10 – 1500 nm) distribution of silver halide crystals in the emulsion. The influence of stirrers in the chemical reactor and also surfactant addition on the emulsion quality was re... Show More
