In the current research, the microstructural changes and corrosion behavior of two-layer Steel/Bronze sheets were investigated after the heat treatment of the explosive welding process. The heat treatment was performed at 600ºC for 16 hr. Dynamic potential polarization, electrochemical impedance spectroscopy, optical microscopy, and scanning electron microscopy analyses were used. Based on of t...

3,3′-Diamino-4,4′-azoxyfurazan (DAAF) is an insensitive explosive and its safety characteristics (sensitivity to impact and friction) are similar to those of 2,4,6-triamino-1,3,5-trinitrobenzene (TATB). This compound has a high nitrogen content (52.7%) and its also suitable for use as a booster charge. DAAF-based explosive formulations, in addition of good performance, are also insensitive and ...

OBJECTIVE Explosive blast mild traumatic brain injury (mTBI) is associated with a variety of symptoms including memory impairment and posttraumatic stress disorder (PTSD). Explosive shock waves can cause hippocampal injury in a large animal model. We recently reported a method for detecting brain injury in soldiers with explosive blast mTBI using magnetic resonance spectroscopic imaging (MRSI)....

Explosive collective phenomena have attracted much attention since the discovery of an explosive percolation transition. In this Letter, we demonstrate how an explosive transition shows up in the synchronization of scale-free networks by incorporating a microscopic correlation between the structural and the dynamical properties of the system. The characteristics of the explosive transition are ...
