    Abstract: The present invention relates to particles of a compound of formula M (I), wherein M is selected from Ni, Pd and Pt, X1 and X2 are each independently of each other sulfur or oxygen, R1, R2, R3, and R4 are independently selected from an unsubstituted, or substituted al- kyl group, an unsubstituted, or substituted cycloalkyl group, an unsubstituted or substi- tuted aryl group and an unsubstituted or substituted heteroaryl group, wherein the particles have a median particle size (D50) in the range of from 30 nm to 90 nm, preferably from 40 nm to 80 nm, more preferably 50 to 70 nm with D10 being greater than 20 nm, especially greater than 25 nm, very especially greater than 30 nm, their use as almost colourless IR absorbers, for optical filter applications, especially for plasma display panels, or for laser welding of plastics. The compounds may be used in compositions for inks, paints and plastics, especially in a wide variety of printing systems and are particularly well-suited for security applications.

    Abstract: The present invention relates to a method of detecting a counterfeit, or adulterated petroleum fuel, comprising: a) emitting a modulated light beam from a modulated light source to a marked petroleum fuel in a chamber, wherein the marked petroleum fuel comprising a fuel additive, a mixture of a fluid petroleum fuel and a marker, wherein the marker is selected from the group consisting of organic IR absorbing compounds and mixtures thereof; b) producing an acoustic signal from the marker in the chamber, in response to the emitted modulated light beam; c) detecting the acoustic signal via a sensor disposed in the chamber; d) transmitting the acoustic signal from the sensor to a processor based module; and determining the marker and a concentration of the marker in the marked petroleum fuel via the processor based module, from the acoustic signal.
