Abstract: Techniques for monitoring production and reuse of a recyclable material, and/or determining a currency or quality measure thereof, are disclosed. In the disclosed embodiments one or more markers are introduced into ingredient material components of the recyclable material, where the one or more markers being indicative of one or more properties of at least one of the ingredient material components. Information indicative of at least the one or more properties is recorded in a database comprising a plurality of records, each associated with at least one of the one or more markers.

Abstract: In one embodiment, a system and a method for inspecting a substance to detect and identify predetermined foreign element(s) in the substance. The foreign element may carry X-ray responding material compositions, emitting X-ray signals in response to primary exciting X-ray or Gamma-ray radiation. The inspection is performed during a relative displacement between the substance and an inspection zone, defined by an overlap region between a solid angle of emission of an X-ray/Gamma-ray source and a solid angle of detection of X-ray radiation, along a movement path, as the substance moves along the movement path, the detected X-ray radiation includes X-ray response signals from successive portions of the substance propagating towards, through, and out of the overlap region. Measured data indicative of X-ray response signals is analyzed to identify a signal variation pattern over time indicative of a location of at least one foreign element carrying an X-ray responsive marker.

Abstract: A process is provided for marking leather manufactured from hide with an XRF-identifiable marker, the process comprising treating a hide or processed leather with a formulation comprising at least one XRF-identifiable marker to embed said marker in the hide or processed leather, to thereby obtain a marked hide or marked leather, wherein the XRF-identifiable marker is not a native material to a hide or leather or involved in a process for its manufacturing.

Abstract: A process is provided for identifying a production and/or commercial history of a silk fiber or a product made therefrom.

Abstract: The invention provides methods and tools for the directed and indirect detection of infection with microorganisms pathogens in biological and non- biological samples, and specifically applications of XRF (X-ray fluorescence) methodology for the detection of infections with viral and bacterial pathogens responsible for the widespread epidemics in mammals and humans, including the current pandemic of COVID-19.
