Abstract: Materials for binding per- and polyfluoroalkyl substances (PFAS) are disclosed. A fluidic device comprising the materials for detection and quantification of PFAS in a sample is disclosed. The fluidic device may be configured for multiplexed analyses. Also disclosed are methods for sorbing and remediating PFAS in a sample. The sample may be groundwater containing, or suspected of containing, one or more PFAS.

Abstract: Nanoporous ion emitters (nano-PIEs) materials promote ionization efficiency of an analyte during thermal ionization mass spectrometry (TIMS). The nano-PIE is a hierarchical material or a modified hierarchical material. The nano-PIE may comprise a coordination polymer (CP), a modified CP, or any combination thereof. Ionization efficiency is promoted by loading the nano-PIE and an analyte on a TIMS filament for subsequent TIMS analysis.

Abstract: Disclosed are adsorbent materials that comprise a porous material having a continuous silica phase coated with a carbon layer, and a water-insoluble precipitate comprising a metal cation and an anion disposed substantially evenly throughout the adsorbent material. In some examples, the plurality of pores can have an average characteristic dimension of from 0.1 ? to 100 ?. The water-insoluble precipitate can be formed in the plurality of pores of the porous material by contacting the porous material with a first aqueous solution comprising a metal cation; and contacting the porous material with a second aqueous solution comprising an anion; wherein the metal cation and the anion combine to form the water-insoluble precipitate in the plurality of pores of the porous material, thereby forming the adsorbent material.
