Current experiments show that the TATB-based polymer bonded explosives (PBX) will experience irreversible growth when suffered temperature cycling load. Although some studies have already been done on this, cause of is still confusing, and mechanism not clear. In order to study PBX under load, an thermal-viscoelastic model established, Based Burgers which considering influence different tempera...

Abstract In order to study the feasibility of acoustic emission technology for damage and fracture monitoring TATB-based PBX materials components, characteristics notched unnotched specimens under uniaxial compression were studied. The results step-cycle experiments showed that there few AE hits with low amplitude strain stage many generated when specimen failed. addition, Kaiser effect is appl...

Recent studies have focused on metal-organic frameworks (MOFs) with high hydrogen uptake1 in order to reach the 2010 DOE targets for on-board vehicular hydrogen storage.2 Strategies such as using pore sizes comparable to hydrogen molecules3 and introducing coordinatively unsaturated metal centers (UMCs)3b,c,4 have been explored. Recently, we have reported a biomimetic approach to UMCs utilizing...

Twin-arginine translocation (Tat) pathways have been well-characterized in bacteria and chloroplasts. Genes encoding a TatC protein are found in almost all plant mitochondrial genomes but to date these have not been extensively investigated. For the first time it could be demonstrated that this mitochondrial-encoded TatC is a functional gene that is translated into a protein in the model plant ...
