摘要： In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05≤(b/c)≤100, and a≥0.

摘要： The present invention is directed to a ligated metal-organic framework (MOF) for use in removing both anionic and cationic species from a liquid or liquid stream. The present invention also provides methods for placing the MOF on a substrate to form a MOF-containing product that can be used in the removal of certain species from a given fluid. The MOF may be a Zr-based MOF, such as NU-1000, for removal of certain anions, such as oxy-anions, or having an attached thiosulfonyl-thiol (—SO2—S—R2—SH, where R2 is an alkyl group) ligand for complexation with certain cationic species in addition to the anions. The substrate may be any substrate to which a given MOF may be attached, including inert polypropylene polymer resin beads, a macroscopic fabric such as a mesh material or mesh filter, and a molecular fabric.

摘要： The present disclosure provides an apparatus for sampling at least one analyte from a sampling fluid. The apparatus includes: a solid-phase microextraction (SPME) sampling instrument. A connector is attached to the SPME sampling instrument and is coupleable to an aerial drone. The apparatus includes a protective cover that is sized and shaped to at least partially surround the SPME sampling instrument. The SPME sampling instrument and the protective cover are movable in relation to each other between a protecting configuration and a sampling configuration. The SPME sampling instrument and the protective cover are (i) biased in the protecting configuration when the density of the fluid surrounding the SPME sampling instrument is less than the density of the sampling fluid; and (ii) biased in the sampling configuration when the density of the fluid surrounding the SPME sampling instrument is equal to or greater than the density of the sampling fluid.

摘要： A bio-inspired method for detoxifying contaminated water is disclosed. In the method, polydopamine, a mussel-inspired adhesive catecholamine was used as an adsorbent to effectively remove from contaminated water three major classes of toxic agents: heavy metal ions (e.g., Cr, Hg, Pb, Cu, and Cd), toxic organic species (e.g., 4-aminopyridine), and radioisotopes (e.g., Lutetium-177). Furthermore, the polydopamine adsorbent was regenerated by treatment with acid or hydrogen peroxide.

摘要： The present invention relates to a super absorbent polymer (SAP) and a preparation method thereof. More specifically, the present invention provides a SAP satisfying the overall properties required to a SAP and especially the superior initial absorbency and absorbing rate under load at the same time, and a preparation method thereof, by treating the surface of the SAP with a surface treatment solution including water and a diol-based or glycol-based surface crosslinking agent.
