Composition B is a melt-castable explosive consisting of RDX crystals in a TNT matrix. At elevated temperatures, the TNT can flow or even melt, which affects the particle distribution and therefore the detonation propagation. To study this phenomenon, rate stick experiments were conducted at ambient conditions, at temperatures below the TNT melt, and at temperatures above the TNT melt. We field...

This work reports a rapid, simple and low-cost voltammetric sensor based on dummy molecularly imprinted polymer (MIP) that uses 2,4-dinitrophenol (DNP) as template for the quantification of 2,4,6-trinitrotoluene (TNT) DNP, identification related substances. Once was synthesised by thermal precipitation polymerisation, it integrated onto graphite epoxy composite (GEC) electrode via sol–gel immob...

In this study titanium dioxide nanotube (TNT) arrays were prepared by an anodic oxidation process with post-calcination. The morphology and structure of the TNT films were studied by field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Photocatalytic activity of the TNT films was evaluated in terms of the degradation of 2,3-di...

Many enteric bacteria express a type I oxygen-insensitive nitroreductase, which reduces nitro groups on many different nitroaromatic compounds under aerobic conditions. Enzymatic reduction of nitramines was also documented in enteric bacteria under anaerobic conditions. This study indicates that nitramine reduction in enteric bacteria is carried out by the type I, or oxygen-insensitive nitrored...

In this study, two cobalt based catalyst samples were prepared on titania and titania nanotubes supports using the deposition precipitation method. Their structural configurations were characterized and compared using BET, and TRP analyses. The BET analysis showed that the surface area of TiO2 is much higher than that of TNT which was due to their structural differences. Analyses of the results...

The preparation and characterization of an amperometric 2,4,6-trinitrotoluene (TNT) biosensor based on the surface immobilization of a maltose binding protein (MBP) nitroreductase (NR) fusion (MBP-NR) onto an electrode modified with an electropolymerized film of N-(3-pyrrol-1-ylpropyl)-4,4'-bipyridine (PPB) are described. The MBP domain of MBP-NR exhibits a high and specific affinity toward ele...

AIM To investigate the relationship between advanced oxidation protein products (AOPPs) and myocardial injury by comparing the selected biomarker for detecting myocardial injury [high-sensitive troponin T (hs-TnT)] in patients with chronic HCV infection. METHODS AND RESULTS Eighty-eight patients with cirrhosis and 40 healthy control subjects were enrolled in the study. Circulating levels of A...
