    Abstract: A droplet formation for fuels is disclosed. The droplet formation for fuels includes an amphiphile. The droplet formation for fuels further includes at least one of an extensional viscosity modifier and a viscosity modifier. The droplet formation for fuels further includes a hydrophilic portion. The droplet formation for fuels further includes a hydrophobic portion. The droplet, including the hydrophilic portion and the hydrophobic portion, includes characteristics selected for beneficial combustion properties. The selected characteristics include flash point, autoignition temperature, density, viscosity, miscibility, size, combustion temperature, organic properties, inorganic properties, zwitterionic properties, micelle properties, and particulate properties.

    Abstract: The invention concerns a method of marking a hydrocarbon liquid comprising the step of adding to said liquid, as a tracer compound, a compound of Formula I or Formula II: wherein at least one of R1-R6 in Formula I and at least one of R7-R14 in Formula II is selected from: i. a bromine or fluorine atom; ii. a partially or fully halogenated alkyl group; iii. a branched or cyclic C4-C20 alkyl group; iv. an aliphatic substituent linking two positions selected from R1-R6 in Formula I to one another or two positions selected from R7-R14 in Formula II to one another; or v. a phenyl group substituted with a halogen atom, an aliphatic group or halogenated aliphatic group and none of R1-R6 in Formula I and none of R7-R14 in Formula II being a sulphonate group or COOR15, where R15 represents H, C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, C3-C15 cycloalkyl or aryl.

    Abstract: A method of fuel analysis comprising subjecting a fuel sample comprising a fuel marker and a fuel matrix to fluorescence spectroscopy to generate a measured emission spectrum comprising a first spectral component (type and amount of marker in sample), a second spectral component (spectral perturbation), and a third spectral component (matrix fluorescence); deconvoluting the measured emission spectrum to yield a deconvoluted measured emission spectrum (first and second spectral components) via removal of third spectral component; decoupling the deconvoluted measured emission spectrum to yield a corrected emission spectrum (first spectral component) via a projection function which orthogonally projects the deconvoluted measured emission spectrum onto a subspace devoid of the second spectral component; and determining the amount of fuel marker in the fuel sample from the corrected emission spectrum. The method of fuel analysis comprises temperature corrections.
