Explosive material - New World Encyclopedia
WebExplosive material has many special characteristics: it is a chemically unstable material, it changes its form very fast and, while changing its form, it explodes by bursting and making loud sounds. There are two types of explosives: low explosives and high explosives. This classification depends on their rate of explosion. WebHigh-explosive (HE) materials (e.g., PETN, RDX, C-4, or TNT) were used to prepare contaminated fingerprints. These were subsequently deposited on various objects, including microscopic glass slides, a table, a mug, etc. Samples deposited on glass slides were directly sent for analyses; for other samples, adhesive tapes were used to lift off ... fitbit charge 2 band replacement instructions
