Far-field positive phase blast parameter characterisation of RDX and PETN based explosives

Trace Detection of RDX, HMX and PETN Explosives Using a Fluorescence Spot Sensor

1,3,5-trinitroperhydro-1,3,5-triazine (RDX), octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), and pentaerythritol tetranitrate (PETN), the major components in plastic explosives, pose a significant threat to public safety. A quick, sensitive, and low-cost detection method for these non-volatile explosives is eagerly demanded. Here we present a fluo-spot approach, which can be employed fo...

A fluorescence turn-on mechanism to detect high explosives RDX and PETN.

Detecting hidden explosive devices in war zones and transportation hubs is a pressing concern. Current efforts have focused on sensing three commonly used powerful explosives: 2,4,6-trinitrotoluene (TNT), 1,3,5-trinitro-1,3,5-triazinane (RDX) and pentaerythritol tetranitrate (PETN) (Chart 1). The need for ultratrace detection of these low-volatility compounds has resulted in an intense interest...

NQR Characteristics of an RDX Plastic Explosives Simulant

For reliable detection of explosives, a combination of methods integrated within a single measurement platform may increase detection performance. However, the efficient field testing of such measurement platforms requires the use of inexplosive simulants that are detectable by a wide range of methods. Physical parameters such as simulant density, elemental composition and crystalline structure...

Atomistic studies of RDX and FOX-7 -Based Plastic-Bonded explosives: molecular dynamics simulation

Molecular dynamics simulations were carried out to study the effects of interface interactions between a crystalline structure and a plastic bonded explosive (PBX) system. In this work, the hydroxyl-terminated polybutadiene (HTPB) represents the polymer, isophorone diisocyanate (IPDI) is the diisocyanate and dioctyl adipate (DOA) is the plasticizer. Two different crystal high explosives compone...
