This study aims to characterize the whole reaction process of (i) emulsion explosive matrix and sulfide ores, (ii) ammonium nitrate pyrite by thermodynamics analysis method. A series experiments were carried out at atmospheric pressure from 25 °C 350 four heating rates (3, 5, 10, 15 K/min) Coats–Redfern method was applied calculate apparent activation energy samples different rates. The results...

there are numerous problems for using essential oil due to its low solubility in water, high vapor pressure and chemical and physical instability. use of nano-emulsions is a good idea for decreasing side effect of the essential oils and enhance their efficiency as well as delivery to hot spot. in addition, nano-emulsion system make smaller size particles and increase stability and shelf-life of...

In the present study, the corrosion behavior and microstructural changes of 5000 series aluminum and copper sheets after the explosive welding process have been investigated. Explosive welding is performed with a fixed stop interval and change of explosive load. Dynamic potential polarization tests and electrochemical impedance spectroscopy, light microscopy, and scanning electron microscopy we...
