The nanoparticle complexes were characterized with TEM, XRD, TG, DSC and IR. The composition of the nanoparticle PbPht complex was determined by chemical and elemental analysis. The catalytic performance of nanoparticle complex on the combustion of RDX-CMDB propellant was investigated. The results showed the average particle size of complex were about 50 nm. The nanoparticle Pb(Ⅱ)-Phtalate complex can enhance burning-rate of propellant by 135%, and lower the pressure exponent by 74%.展开更多
Highly oriented cubic, hollow cubic and spherical nanoparticles of cobalt-iron Prussian blue analogues were synthesized in poly oxyethylene tertoctylphenyl ether (TritonX-100)/n-hexanol/cyclohexane microemulsion. The ...Highly oriented cubic, hollow cubic and spherical nanoparticles of cobalt-iron Prussian blue analogues were synthesized in poly oxyethylene tertoctylphenyl ether (TritonX-100)/n-hexanol/cyclohexane microemulsion. The effects of the water-to-surfactant molar ratio (w), the reactant concentration and the reaction temperature on the morphology of cobalt-iron Prussian blue analogues were studied. The samples were characterized by transmission electron microscopy (TEM), field emission scan electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and infrared spectroscopy (IR).展开更多
The crystal structure of Eu(TFPB)3bpy [TFPB: 4,4,4-trifluoro-1-phenyl-1,3- butanedione, bpy: 2,2′-bipyridyl] has been determined by single crystal X-ray diffraction and the coordination geometry of Eu atom is a squar...The crystal structure of Eu(TFPB)3bpy [TFPB: 4,4,4-trifluoro-1-phenyl-1,3- butanedione, bpy: 2,2′-bipyridyl] has been determined by single crystal X-ray diffraction and the coordination geometry of Eu atom is a square antiprism. The complex can give the characteristic luminescence of Eu3+ upon UV excitation. CCDC: 224879.展开更多
