Abstract:
The present invention relates to moving microorganisms to a surface, where they are grown in the presence and absence of antimicrobials, and by monitoring the growth of the microorganisms over time in the two conditions, their susceptibility to the antimicrobials can be determined. The microorganisms can be moved to the surface through electrophoresis, centrifugation or filtration. When the movement involves electrophoresis, the presence of oxidizing and reducing reagents lowers the voltage at which electrophoretic force can be generated and allows a broader range of means by which the target can be detected. Monitoring can comprise optical detection, and most conveniently includes the detection of individual microorganisms. The microorganisms can be stained in order to give information about their response to antimicrobials.

Abstract:
A system for the rapid detection of microbial contamination in a fluid sample such as water, involving the use of a filter material having a surface adapted to receive the sample in order to retain substantially all microbes from the sample on the filter surface under conditions that minimize the potential for contamination from sources other than the sample itself, and in a manner that permits the filter surface to be incubated in order to grow viable microbes contained thereon, in combination with a growth medium and an analytic instrument to permit analysis of the filter surface, within a predetermined incubation period, in order to determine whether the growth onset of viable microbes that may be present on the surface has begun.
Abstract:
Adhesion between carbon fibers and thermoplastic matrix materials, used in carbon fiber composite materials, is promoted by the use of a bridging agent. The composite material includes: a plurality of carbon fibers; a thermoplastic matrix material intermingled among the plurality of carbon fibers; and a bridging agent adhering the plurality of carbon fibers to the thermoplastic matrix material. The bridging agent includes compounds having multifunctional groups that are capable of chemically bonding with a functional group of the carbon fiber and a functional group of the thermoplastic matrix material; but it excludes multifunctional amine compounds having metal-oxygen bonds.
Abstract:
Ionic liquids suitable for use in magnesium batteries are disclosed. In an exemplary embodiment, a rechargeable magnesium battery comprises an anode electrode, a cathode electrode, and a chelating ionic liquid solution in contact therewith. The chelating ionic liquid may comprise at least one cation, at least one anion, and at least one soluble, magnesium salt. The magnesium salt may comprise MgX2, wherein X comprises at least one of Cl—, Br—, I—, TFSI—, FSI—, ClO4—, BF4—, PF6—, RSO3— (wherein R consists of at least one of an alkyl or aryl group), RCO2— (wherein R consists of at least one of an alkyl or aryl group), alkyl borides, alkyl borates, AlCl4—, AlXaRb— (wherein the sum of subscripts a and b is 4, X consists of a halide, and R consists of at least one of an alkyl or aryl group), carboranes, or hexamethyldisilazide.

Abstract:
Carbon dioxide capture and release includes contacting a gas comprising carbon dioxide with a mixture comprising a precursor and a solvent and reducing the precursor to form a capture agent. The capture agent is reacted with the carbon dioxide to form a non-volatile species containing carbon dioxide. The non-volatile species is oxidized to regenerate the precursor and to release carbon dioxide. The mixture may be formed by combining the precursor and the solvent.
Abstract:
The invention includes a method of simultaneously detecting the presence or absence of more than one microbe class (e.g., bacteria, yeast, and mold) in a sample. The method can include the step of applying a sample suspected of containing more than one microbe class to a growth medium, optionally fragmenting the sample, associating the sample with a labeling agent, and simultaneously detecting the presence or absence of each microbe class by detection of the labeling agent.
Abstract:
A method for the detection of microorganisms in a sample comprising contacting said sample with a biosensor concentration module, allowing microorganisms to grow for a first period of time and detecting growth of discrete microorganisms as an indication of the presence of said microorganisms.
