2.2. Methods 2.2.1. Preparation of econazole nitrate nanoparticles The econazole nanoparticles were prepared by nano-spray drying technique. Weighed amounts of econazole nitrate, carriers and stabilizers (table 1) were dissolved in ethanol (10 ml) followed by spraying through the Buchi® nano-spray dryer B-90 (Büchi Labortechnik, Switzerland). The nano-spray dryer was operated using inert loop B-295 system (Büchi Labortechnik AG, Flawil, Switzerland) operated using nitrogen gas with flow rate of…

fashion with furniture, cutlery, clocks etc engraved and decorated with hot air balloons. The French Academy des Sciences were honed for their work on hot air ballooning. They also published a book on aeronautics, invented the hydraulic ram and the calorimeter. On the American continent balloon flight was developing and the first manned flight took place on the 9th January 1793 the pilot was Jean- pierre Blanchard. George Washington observed the launch.
