Abstract The introduction of carbon nanotubes (CNTs) in the preparation nano-lead oxide (PbO) can effectively solve problem easy agglomeration oxide. This study used concentrated nitric acid and sulfuric mixed (volume ratio 1:3) to oxidize at 90 °C temperature for 0.5 h. Using oxidized CNTs as carriers, Pb(OAc) 2 · 3H O precursor, ammonia a precipitator, PbO/CNTs complexes were prepared by chem...

Commercial explosives are complex mixtures that contain not only the active explosive agent(s) but also a host of other organic and inorganic compounds. The ultrahigh mass resolving power (m/delta m50% >200,000) and mass accuracy (<1 ppm) of electrospray ionization Fourier transform ion cyclotron resonance (ESI FTICR) mass spectrometry allow for definitive identification of various species in T...

Environmental contamination by explosives is a worldwide problem. Of the 20 energetic compounds, 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) are the most powerful and commonly used. Nitroamines are toxic and considered as possible carcinogens. The toxicity and persistence of nitroamines requires that thei...

A 15-week treatability study was conducted in a greenhouse to evaluate the potential effects of molasses on the bioremediation and phytoremediation potential of Guinea Grass (Panicum maximum) for treating energetic contaminated soil from the open burn/open detonation area of the Makua Military Reservation, Oahu, HI (USA). The energetics in the soil were royal demolition explosive (RDX) and high...

In order to study the ignition process and response characteristics of cast polymer-bonded explosives (PBX) under action friction, HMX-based PBX were used carry out friction experiments at a 90° swing angle obtain critical loading pressure was 3.7 MPa. Combined with morphology characterization results PBX, temperature rise numerically simulated macro micro scale, judged. The accuracy numerical ...

The thermal decomposition and ignition of high-performance high explosives occur via a mechanism where the solid phase sublimes parent molecules decompose rapidly in gas to form unstable charged intermediates. These intermediates continue react final products release energy do work. We have observed that presence electromagnetic significantly reduces temperature common explosive, data suggest t...

Klapötke and co-workers recently designed two new materials, 2,4,6-triamino-1,3,5-triazine-1,3,5-trioxide (MTO) and 2,4,6-trinitro-1,3,5-triazine-1,3,5-trioxide (MTO3N), envisioned as candidates for green highenergy materials. However, all attempts at synthesis have failed. In order to validate the expected properties for these systems and to determine why these materials are too unstable to sy...
