2021-10-13 In this paper, we report the performance evaluation of praseodymium doped fiber amplifier (PDFA) operating in 1.25–1.35 μm band of wavelengths based on theoretical simulation. The performance of the PDFA is evaluated by considering an optimized length of Pr $$^{3+}$$ 3 + doped fiber, concentration of Pr $$^{3+}$$ 3 + ions and pump power. Moreover, the impact of input signal

The Si-BaSO4 composition supported combustion in the range of 20–60 wt% Si in the bomb calorimeter. However, burning was only sustained between 20 and 40 wt% Si in rigid aluminum tubes, with burning rates of between 8.4 and 16 mm s−1. These values are comparable to those for the Si-CaSO4 system (6.9–12.5 mm s−1).

2017-4-18 Aluminized explosives have been applied in military industry since decades ago. Compared with ideal explosives such as TNT, HMX, RDX, aluminized explosives feature both fast detonation and slow metal combustion chemistry, generating a complex multi-phase reactive flow. Though aluminized explosives have been employed for a long time, the mechanism underneath the chemical process is
