Abstract: The invention subject of the present application concerns sorting of black plastics.

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

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: There are disclosed a method of producing an XRF readable mark, the XRF readable mark and a component comprising thereof. The method comprises providing an XRF marking composition with specific relative concentrations of one or more chemical elements and fabricating a multilayer structure of the XRF readable mark. The relative concentrations are selected such that in response to irradiation of the XRF marking composition by XRF exciting radiation, the XRF marking composition emits an XRF signal indicative of a predetermined XRF signature. Fabricating the multilayer structure comprises implementing an attenuation layer with at least one element exhibiting high absorbance for an XRF exciting radiation and/or an XRF background; and implementing a marking layer comprising said XRF marking composition.

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.

Abstract: The invention concerns compositions and methods for authenticating an agricultural product.

Abstract: The present invention is in the field of polymers comprising identifiable tracers by spectroscopic methods such as XRF, IR, NIR and XRD allowing information to be encoded by the polymers, and in particular polymers for conservation, restoration and retouching in artworks, electronics, coatings, plastics, packaging, 3D printing, rubber, and the like.

Abstract: Methods and systems for verifying compatibility of components (e.g. parts or devices) of an electronic system are disclosed. In certain embodiments the method includes: irradiating a first and second components presumably associated with the electronic system, with XRF exciting radiation, and detecting one or more XRF response signals indicative of a first and a second XRF signatures, emitted from the first and second components in response to the irradiation. Then the first and second XRF signatures are processed to determine whether they are associated with respectively a first and second XRF marking compositions on the first and second components, and the compatibility of the first and second components to the electronic system is determined/verified based on the correspondence between the first and a second XRF signatures/marking.

Abstract: A hybrid inorganic-organic composite comprising a nanostructure of a metal chalcogenide and at least one compound comprising an organic cyclic moiety, wherein the compound is linked to the nanostructure, is provided. A nanotube of metal chalcogenide (e.g., metal dichalcogenide) nanostructure having attached to at least one surface thereof one or more selected chemically reactive nanoparticles is also provided.
