    Abstract: The present disclosure provides a method of detecting the presence of and/or the amount of at least one fungal plant pathogen in a sample. The method comprises contacting the at least one fungal plant pathogen with at least one biological component that specifically binds to the at least one fungal plant pathogen in a liquid sample, detecting, such as imaging and/or measuring the impedance of, at least a portion of the liquid sample, and correlating the detection with the presence and/or the amount of the at least one fungal plant pathogen in the liquid sample. The present disclosure also provides a sample trap device for performing the method.

    Abstract: Asphalt binders and related methods and uses are provided. In some embodiments, the asphalt binder is produced by: providing a high-asphaltene content petroleum feedstock; performing solvent deasphalting on the feedstock to produce a partially deasphalted oil and an asphaltene-rich residue; and collecting the partially deasphalted oil (DAO). The high-asphaltene content petroleum feedstock may comprise residue from vacuum distillation or flash separation of extra heavy oil or bitumen, or recycled asphalt. The DAO may itself be used as the asphalt binder or may be a component of a blend with the original feedstock. Asphalt binders may also be produced by blending residue and heavy distillate produced from vacuum distillation or flash separation, with DAO or the asphaltene-rich residue of the solvent deasphalting process. The disclosed methods allow for production of asphalt binders of a wide variety of performance grades.

    Abstract: A device and method to reduce molecular background emission and to increase matrix management in solution cathode glow discharge (SCGD). A purging device for purging atmospheric gases from a solution cathode glow discharge (SCGD) apparatus, comprising a hollow body that encloses a plasma generated between a solid anode and a solution cathode, wherein the body comprises at least one opening for release of water vapor generated by the plasma. A method for reducing matrix interferences from a SCGD comprising introducing an internal standard into a sample to be analyzed, wherein the sample comprises at least one element of interest; determining a spatial emission profile of the internal standard; using linear correlation between the spatial emission profile of the internal standard and the element of interest to predict a crossover point; and using the crossover point of the element of interest to select a vertical acquisition height for SCGD analysis.
