Nanothermites are interesting energetic systems as their combustion driven by the oxidation of metallic fuel associated with reduction oxidizer, can produce extremely fast burning rates exceeding hundreds m s−1. In addition, changing reactant (composition, stoichiometry) geometry and compaction conditions, control rate be achieved, allowing designer to customize chemical energy for each applica...
oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...
This paper reviews the localized microwave-heating (LMH) phenomenon and its various applications in a paradigmatic approach. A simplified 1-D microwave-heating model is derived for a temperaturedependent dielectric medium in a cavity. This semi-analytical model shows the evolution of high-order spatial modes, and the concentration therein of the dissipated power. The LMH effect is associated wi...
This paper presents experimental characterization of plasmoids (fireballs) obtained by directing localized microwave power (<1 kW at 2.45 GHz) onto a silicon-based substrate in a microwave cavity. The plasmoid emerges up from the hotspot created in the solid substrate into the air within the microwave cavity. The experimental diagnostics employed for the fireball characterization in this study ...
To have a safe and reliable railway system, nondestructive testing (NDT) methods are necessary to be implemented in order to avoid catastrophic failures. NDT methods also provide a powerful tool for proper maintenance of valuable railway system assets. Among various NDT methods, ultrasonic testing (UT) along with magnetic particle testing (MPT) and eddy current testing (ECT) play significant ro...
The shock compression of spatially-resolved particle systems is studied at the mesoscale through a series of finite element simulations. The simulations involve propagating shock waves through aluminium–iron oxide thermite systems (Al+Fe2O3) composed of micron-size particles suspended in a polymer binder. Shock-induced chemical reactions are not considered in this work; the particle systems are...
