Abstract: A method for devulcanization of rubber feedstock and a related arrangement are provided. The method includes doping rubber feedstock with a photoactive substance (104, 110), configured to activate upon exposure thereof to external radiation of a predetermined wavelength; and further exposing cured rubber feedstock to the external radiation of the predetermined wavelength. Radiation exposure results, upon photoactive substance activation, in initiation of selective scission of intermolecular crosslinks, such as sulfur crosslinks, in the vulcanized rubber elastomers. The photoactive substance may be configured to initiate an excitation emission response and/or chemical reaction. The photoactive substance is preferably selected from semiconducting nanocrystals, such as quantum dots. An arrangement for carrying out the method is presented.

Abstract: A hybrid pixel detector structure including a plurality of detector entities, each detector entity including at least one read-out element, such as a read-out ASIC, and an overlapping substantially edgeless radiation sensitive detector volume, these two being electrically coupled utilizing a number of conductive elements in between, further including a substrate, such as a circuit board, or multiple substrates such as one per detector entity, for accommodating the plurality of detector entities, wherein the substantially edgeless detector volume of at least one detector entity of the plurality includes an overhang portion outside the overlap between the detector volume and the read-out element, and the read-out element of at least one other detector entity of the plurality includes an extension portion, also outside the overlap, with a number of electrical coupling elements to electrically couple to the substrate, such as conductors and/or electronics thereof.
