How the C-Subunit Stoichiometry of F1F0 ATP Synthase Controls Bio-Energetic Thermodynamic Efficiency
The Lighthill acoustic analogy indicates that substantial noise reduction is possible in high-speed jets by reducing the radiation efficiency. This entails reducing the convective Mach number of the eddies whose footprint is sensed in the near pressure field. In dualstream jets, local reduction in convective Mach number is possible by inducing asymmetry in the plume that redistributes the most ...
In this work, thermal degradation behavior of a fuel-rich energetic mixture containing epoxy binder was studied by thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. Variation of the thermal degradation activation energy of the mixture was evaluated by differential and integral isoconversional methods via ...
the synthesis of 3-amino-1-nitroguanidine (3-anq) and 5-hydrazino tetrazole (5-ht) derivatives as new energetic materials are described. reaction of 3-anq with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-ht. addition of nan3 to a mixture of 3-anq and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excellent yield. on th...
