Encapsulation is proposed as a safer way of handling energetic materials. Different encapsulation methods for explosives, such solvent evaporation, spray coating and supercritical carbon dioxide assisted encapsulation, were explored. Explosive training aids, where materials, triacetone triperoxide (TATP), erythritol tetranitrate (ETN) trinitrotoluene (TNT), are encapsulated in polymer matrix de...
Pyrene-based compounds have a great potential as fluorescent chemosensors for various analytes including common nitro-explosives, such 2,4,6-trinitrotoluene (TNT). Compounds having two pyrene units in one molecule, bispyrenylalkanes, are able to form stable, bright emissive visual wavelength region excimers both non-polar and polar environments. In this work we wish report that solvents the exc...
Tunneling nanotubes (TNTs) are recently discovered thin membranous tubes that interconnect cells. During the last decade, research has shown TNTs to be diverse in morphology and composition, varying between and within cell systems. In addition, the discovery of TNT-like extracellular protrusions, as well as observations of TNTs in vivo, has further enriched our knowledge on the diversity of TNT...
Data from a combination of laboratory and fieldwork is presented to initiate testing of stable carbon and nitrogen isotope ratios to trace sources of TNT in contaminated soil and groundwater. Evaluation of these extraction methods resulted in 99.9 and 99.8% recovery of TNT with Soxhlet and solid-phase extraction (SPE), respectively. As a result of the high extraction efficiency, isotope fractio...
Doppler weather radar imaging enabled the rapid recovery of the Sutter's Mill meteorite after a rare 4-kiloton of TNT-equivalent asteroid impact over the foothills of the Sierra Nevada in northern California. The recovered meteorites survived a record high-speed entry of 28.6 kilometers per second from an orbit close to that of Jupiter-family comets (Tisserand's parameter = 2.8 ± 0.3). Sutter's...
