Recent years have seen the development of powerful technologies that have provided forensic scientists with new analytical capabilities, unimaginable only a few years ago. With liquid chromatography-mass spectrometry (LC-MS) in particular, there has been an explosion in the range of new products available for solving many analytical problems, especially for those applications in which non-volat...

With the explosive growth of the internet, autonomous agents will increasingly need strategies for efficiently retrieving information. The time an agent (or server) takes to answer a query issued to it is often a random variable, whose distribution can be estimated by collecting statistics. When an agent A sends a query to another agent B and the query has not completed in some period of time, ...

Ionic Liquids are salts that are liquid at (or just above) room temperature. They possess several advantageous properties (e.g. high intrinsic conductivity, wide electrochemical windows, low volatility, high thermal stability and good solvating ability), which make them ideal as non-volatile electrolytes in electrochemical sensors. This mini-review article describes the recent uses of ionic liq...

Abstract In order to improve the detonation performance of explosive network on basis achieving high safety and reliable detonation, 3,4-dinitrofurazanyl oxyfurazan (DNTF) was used as main explosive, glycidyl azide polymer(GAP) binder, other auxiliary agents were added basic charge formula. Then, polytetrafluoroethylene (PTFE) aluminum (Al) introduced further enhance output power The influence ...

Contamination of groundwater, surface water and soil by explosives has occurred at military sites throughout the world as a result of manufacture of explosive compounds, assembly of munitions, and deployment of explosives containing devices. Due to the adverse effects of explosives on humans and other natural receptors, a low cost means of decontaminating these areas of contamination is needed....

We demonstrate that the selectivity of microchip electrophoresis separations is greatly improved by the presence of organically modified silica (Ormosil) sols in the run buffer. A negatively-charged N-(trimethoxysilylpropyl)ethylenediamine triacetic-acid (TETT)-based sol is used for improving the selectivity between nitroaromatic explosives and a methyltrimethoxysilane (MTMOS)-based sol is empl...

1993 Number 21 Los Alamos Science As we look back on the fifty-year history of Los Alamos National Laboratory, we can be justifiably proud of the accomplishments that are the foundation of our rich heritage. While the nation faced World War II and then the Cold War, we developed nuclear and thermonuclear explosives. In the early years we were also instrumental in developing the manufacturing te...

When an explosive detonates or a propellant or flare burns, consumption of the energetic filler should be complete but rarely is, especially in the presence of large amounts of non-combustible materials. Herein we examine three types of perchlorate-containing devices to estimate their potential as sources of contamination in their normal mode of functioning. Road flares, rocket propellants and ...
