2-Chloroethyl ethyl sulfide (CEES) is a simulant for the chemical warfare agent, bis(2-chloroethyl) sulfide, also known as mustard gas. Functionalized Zr-BTC synthesized and exploited optical detection of CEES.

An innovative chromogenic sensing concept based on decomplexation of a tris-(bipyridine)iron(II) coordination complex has been developed for the detection of organophosphorus nerve agents. It was evaluated both on a simulant and real Sarin in vapour and liquid phases.

The detoxification of nerve agents, a class extremely toxic chemical warfare is urgently needed because they have remained threat to humanity. To date, zirconium-based metal-organic frameworks (Zr-MOFs) are the most popular catalysts in this realm. However, it still essential develop new and efficient based on Zr-MOFs achieve more rapid hydrolysis. Herein, we report that single-atom catalyst (S...

The nerve agent VX (O-ethyl S-[2-(diisopropylamino)ethyl]methylphosphonothiolate) has been shown to decompose in contact with concrete surfaces. We have previously shown that 31P NMR can be employed to study 1) the adsorption of VX into concrete; 2) the decomposition kinetics; and 3) detect decomposition products. Recently reported results show a dramatic effect of the VX decomposition kinetics...

Incidents involving the release of chemical agents can pose significant risks to public health. In such an event, emergency decontamination of affected casualties may need to be undertaken to reduce injury and possible loss of life. To ensure these methods are effective, human volunteer trials (HVTs) of decontamination protocols, using simulant contaminants, have been conducted. Simulants must ...

Three Low Molecular Weight Fluorescent probes (LMFPs) coumarin-enamine (3a-c) have been synthesized, and their photophysical properties studied in different solvent systems (DMSO, CH3CN, DMF, MeOH, EtOH, Me2CO, MeCO2Et, CHCl3, C6H5Me, C6H6). Dimethyl sulfoxide was chosen as the optimum to investigate 3a for organophosphate detection. On deprotonation of oxime, a significant spectroscopic shift ...

For reliable detection of explosives, a combination of methods integrated within a single measurement platform may increase detection performance. However, the efficient field testing of such measurement platforms requires the use of inexplosive simulants that are detectable by a wide range of methods. Physical parameters such as simulant density, elemental composition and crystalline structure...

A series of supramolecular diamide organogels containing a reactive compound for the remediation of organophosphorus (OP) species, in particular OP chemical warfare agents (CWAs), has been prepared in DMSO. The organogels have been found to absorb, encapsulate and decontaminate various OP CWA simulants in situ. At high simulant concentrations the gels also undergo a gel-sol transition releasing...
