Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

4-[4-(4-Amino-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazol-3-yl]-1,2,5-oxadiazol-3-amine [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
The complete molecule of the compound, C(6)H(4)N(8)O(3), is generated by a crystallographic twofold rotation axis that runs through the central ring. The flanking ring is twisted by 20.2 (1)° with respect to the central ring. One of the amino H atoms forms an intra-molecular N-H⋯N hydrogen bond; adjacent mol-ecules are linked by N-H⋯N hydrogen bonds ...

Comparative Assessment of Energetic Plasticizers Including NFPEG3N3 in a GAP/HMX Formulation: Mechanics, Stability, Combustion, and Performance

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We examine the new energetic plasticizer 3‐(2‐(2‐(2‐azidoethoxy)ethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG3N3), three reference compounds (BDNPA/F, Bu‐NENA, and DNDA‐57), and a plasticizer‐free control in a fixed HMX/GAP composite. NFPEG3N3 provides the strongest low‐temperature properties, yielding the lowest formulation glass transition ...
