Sparsity‐Driven Source Localization in Tomographic Sensing Applications

ABSTRACT Hyperspectral standoff detection systems such as Focal Plane Array (FPA) Fourier Transform Infrared (FTIR) spectrometers provide high spatial resolution in detecting airborne chemical contaminants that are invisible to the human eye but potentially hazardous. When two su...

Indirect Detection of Novichok Nerve Agents A-230, A-232, and A-234 by Ion Mobility Spectrometry: Limitations of Hydrolysis-Based Marker Strategies

Abstract Ion mobility spectrometry (IMS) is widely used for on-site detection of chemical warfare agents due to its high sensitivity and rapid response times. While volatile G-series nerve agents can be detected directly in the gas phase, detection of low-volatility agents such a...
