Abstract:
Magnet configuration. The configuration includes a magnet holder and at least one elongate magnet extending from the magnet holder so that less than one half of the magnet length extends from the holder, whereby a magnetic fluid adjacent the elongate magnet is attracted toward a top edge of the elongate magnet for subsequent removal.
Abstract:
Disclosed are capacitors containing surface active ionic liquids, and methods of use. The capacitors have high capacitance and function over broad ranges of temperature, and are particularly appropriate for high-temperature (˜200° C.) applications.
Abstract:
Disclosed are methods for using ionic liquids to extract metal ions from aqueous solution, and for subsequent recovery of the metal ions from the ionic liquids by electrochemical methods. The ionic liquids may be recycled and reused for further extraction.
Abstract:
Disclosed are methods of extracting metal ions using ionic liquids (ILs), IL complexes, and mixtures comprising an IL and a metal-chelating group. Also disclosed are IL complexes, and mixtures comprising an IL and a metal-chelating group.
Abstract:
Disclosed are polymer-coated surfaces encapsulating task specific ionic liquids (ILs), IL complexes, or oils. Also disclosed are polymer-coated surfaces, wherein the polymer comprises ILs or neutral ethylene diamine compounds. Also disclosed are methods of antimicrobial treatment, metal remediation, and gas absorption using polymer coatings encapsulating ILs, IL complexes, and oils or polymer coatings comprising ILs and neutral ethylene diamine compounds.
Abstract:
Polyamines are water-soluble polyelectrolytes with the amino groups that can be used to attach the polymers onto functional surfaces of fibrous materials. In addition, polyamines can be readily modified by (super)nucleophilic groups such as (alkyl)aminopyridines that enhance the polymer's ability to promote hydrolysis of organophosphorous chemical warfare agents. Furthermore, attachment of hydantoin moieties augments the number of the imide, amide, or amine groups groups on the polyamine's chain, which provides oxidizing properties to the resulting modified polyamine after halogenation. In one aspect, disclosed herein are polyamines with side chains modified to contain both (4-aminopyridine, APy) and 5-(4-hydroxybenzylidene)hydantoin (HBH) functionalities with enhanced content of the active bromine. Viricidal activity of the APy- and HBH-modified polyallylamine against human coronavirus (type 229E) was tested both in solution and on nylon-cotton fabric. The polymers are effective at inactivating the coronavirus, at both low concentrations and short exposure times.

Abstract:
Disclosed are compositions comprising composite nanoparticles and a reporter molecule for use in detecting the presence of an analyte in a substrate. The composite nanoparticles comprise a solid core and a polyampholyte covalently bonded to the solid core. Reporter molecules are releasable from the composite nanoparticles upon exposure to the analyte. Analytes may include petroleum or other hydrophobic media.
