Stability Assessment for Double Base Rocket Propellant During Long Natural/Artificial Aging Using Vndard. Nevertheless, the VST results present some issues when compared to the same standard. Furthermore, the VST finding revealed three degradation stages during the aging of the DBRP. Kinetic modeling indicates a decrease in the activation energy value with aging progress and a change in the most

Synthesis and Characterization of Microcrystalline Cellulose from Giant Reed Using Different Deligne a higher thermal stability. Moreover, the use of a totally chlorine-free process allowed obtaining MCC with higher crystallinity and thermal stability. Consequently, giant reed can be considered as a potential source to extract MCC for which the green totally chlorine-free is a prominent process t

Bioactive Compounds and Antioxidant Activity of Ethanolic Extracts from the Leaves of , (Vahl) Mast. The highest extraction yield of total phenolic (95.28 mg GAE/g) and flavonoid (36.70 mg QE/g) compounds was obtained with 60% ethanol concentration for an extraction time of 210 min and 120 min, respectively. The best antioxidant activity was obtained from the . leaves extracted for an extraction
