Characterization of Functional Nanoscale Materials for Vapor Sensing


EMSL Project ID
12302

Abstract

Materials will be characterized in a variety of configurations including powders, pelletized beds, and thin films. These will generally be coupled to acoustic sensors for characterization as vapor sensing media and preconcentrators. Materials will be composed of nanoscale materials with specific chemical functionality imparted to their surfaces. Such functionality allows selective adsorption of target analytes for sensing applications. In addition to vapor blending and acoustic measurements in EMSL 1405, the wet lab in EMSL 1310 may be used for synthetic needs. Several of the characterization capabilities will also be used including TGA/DSC, electron microscopy, and possibly NMR.
