We can’t preclude the possibility of the use of chemical agents by terrorists I can recall the attempt committed with Sarin in the Tokyo-subway in 1995. For that reason it is necessary to know the chemical situation in the battlefield and in our urban environment as well, for example in the subway. Actually the possible detection principles of toxic-agent-detection-devices are chemical (simple ...

We created a spiking neural controller for an agent that could use two different types of information encoding strategies depending on the level of chemical concentration present in the environment. The first goal of this research was to create a simulated agent that could react and stay within a region where there were two different overlapping chemicals having uniform concentrations. The agen...

This paper describes the development of a method to calculate the overall "greenness" of a pharmaceutical process that uses multiple solvents. This calculation is made by taking into account various environmental parameters and determining an overall greenness index. Through this method a scientist or engineer can effectively determine alternative, "greener" solvents or processes based on the u...

Two relatively new types of exogenous magnetic resonance imaging contrast agents may provide greater impact for molecular imaging by providing greater specificity for detecting molecular imaging biomarkers. Exogenous chemical exchange saturation transfer (CEST) agents rely on the selective saturation of the magnetization of a proton on an agent, followed by chemical exchange of a proton from th...

We present a theory for Raman scattering by current-carrying molecular junctions. The approach combines a nonequilibrium Green's function (NEGF) description of the nonequilibrium junction with a generalized scattering theory formulation for evaluating the light scattering signal. This generalizes our previous study [M. Galperin and A. Nitzan, Phys. Rev. Lett. 95, 206802 (2005); J. Chem. Phys. 1...

A flow reactor was designed, manufactured by 3D printing, and modified to promote the selective ethanolysis of a chemical warfare agent VX surrogate.

Interactions between two or more toxic agents can produce lung damage by chemical-chemical interactions, chemical-receptor interactions or by modification, by a first agent, of the cell and tissue response to a second agent. Interactions may occur by simultaneous exposure and if exposure to the two agents is separated in time. Chemical-chemical interactions have been mostly studied in the toxic...
