Porous organic polymers allow the integration of various π-units into robust porous π-networks, but they are usually synthesized as unprocessable solids with poor light-emitting performance as a result of aggregation-related excitation dissipation. Herein, we report a general strategy for the synthesis of highly emissive photofunctional porous polymer films on the basis of a complementary schem...

A novel molecular descriptor index, viz., TG index, has been defined for modeling and estimation of detonation parameters of explosives. The index is simple to calculate, unique for each molecule and is applicable to the heteroatom containing species. The results of the correlation analyses of the TG index with the explosion data indicate that the TG index can be a very successful tool for pred...

GENOMES: With the DNA sequencing of most key model organisms finished or well on the way, one genomics institute is filling an important niche, using novel criteria to take on species from organisms that occupy a unique place in the evolutionary tree to others that have an ability to digest explosives.

The volume of research on terrorism has increased since the events of September 11, 2001. However, efforts to develop a contextualized model incorporating cognitive, social-contextual, and affective factors as predictors of individual responses to this threat have been limited. Therefore, the aim of this study was to evaluate a series of hypotheses drawn from such a model that was generated fro...

The absorption spectrum of the explosive 1,3,5-trinitro-1,3,5-triazacyclohexane sRDXd has been measured using a conventional Fourier transform infrared spectroscopy and by terahertz pulsed spectroscopy. Seven absorption features in the spectral range of 5–120 cm−1 have been observed and identified as the fingerprint of RDX. Furthermore, the spatial distribution of individual chemical substances...

Means are required to assess hazards by small-scale experiments. Those commonly used are based upon the science of conventional explosives with important modifications. Several types of explosion may occur: a detonation, propagating supersonically; a deflagration, propagating subsonically; so-called homogeneous explosion in which reaction occurs almost simultaneously throughout the mass. The ev...

We report a simple and inexpensive electrochemical assay using a custom built hand-held potentiostat for the identification of explosives. The assay is based on a wipe test and is specifically designed for use in the field. The prototype instrument designed to run the assay is capable of performing time-resolved electrochemical measurements including cyclic square wave voltammetry using an embe...

The efficient allocation of medical resources to prepare for and respond to mass casualty events (MCEs) attributable to intentional acts of terrorism is a major challenge confronting disaster planners and emergency personnel. This research article examines variation in regional patterns in the causes of injures associated with 77,258 successful terrorist attacks that occurred between 1970 and 2...

We analyze the definition of the Gibbs free energy of a nanoparticle in a reactive fluid environment, and propose an approach for predicting the size of carbon nanoparticles produced by the detonation of carbon-rich explosives that regards their condensation as a nucleation process and takes into account absolute entropy effects of the cluster population. The results are consistent with experim...

"Biological terrorism is more likely than ever before and far more greatly to be feared than explosives or chemicals."
