    Abstract: The invention relates to an additive manufacturing system (1) and a method for manufacturing one or more three-dimensional structures. At least one deposition unit (3) with one or more nozzles (5) is arranged for dispensing a build material through an opening area thereof on a print surface (7). A controller is provided which is configured to operate the system (1) for deposition of filaments of a build material paste on the print surface (7) in an interconnected arrangement in a plurality of stacked layers in order to form the one or more three-dimensional structures. An actuation unit (9) is arranged in order to have printing access to the at least one deposition unit (3), wherein the actuation unit (9) is configured to hold the print surface. The controller is configured to control the actuation unit (9) so as to move the print surface (7) at the at least one deposition unit (3) during deposition of the filaments by said deposition unit. The one or more nozzles (5) of the at least one deposition unit (3) are arranged to remain stationary during the deposition of the filaments.

    Abstract: A process prepares an oxygen carrier for a chemical looping process including providing a material A having a first transition metal and/or an oxide of the first transition metal. The first transition metal is selected from chemical element groups 6-11 of the Periodic System. Material A is subjected to a reaction with H2 to reduce the first transition metal and/or oxide to form a reduced material B. Material B is treated with a salt solution of a second transition metal selected to have a standard reduction potential larger than the first transition metal. A portion of the first transition metal in the reduced material B is replaced by the second transition metal. A molar ratio of the first transition metal with respect to the second transition metal in material B ranges between 2:1 and 100:1. An oxygen carrier is obtained with the method and is regenerated using steam.

    Abstract: A method and system for printing a three-dimensional porous structure (1). Interconnected filaments (2) are deposited in a predetermined arrangement in a plurality of stacked layers (11). The filaments (2) of the consecutive layers (11) are connected to one another to obtain the porous structure (1) with interconnected pores (15). The filaments are deposited in such a way that one or more preselected frangible regions (7) are formed in the arrangement of filaments (2). The one or more frangible regions (7) are connected to less-frangible regions (9) of the porous structure (1). The predetermined arrangement of interconnected filaments (2) is configured such that the one or more frangible regions (7) form structurally weakened zones of the porous structure (1) such that the porous structure (1) breaks along said one or more frangible regions (7) under influence of a load and/or a stress. The plurality of three- dimensional parts (10a) are releasable under influence of the load and/or stress.

    Abstract: An assembly includes a housing with opposite first and second layers. The first and second layers are spaced apart to define a confined interior space. A semi-permeable membrane is attached to the first layer, the semi-permeable membrane covering a porous area portion of the first layer. An outlet port and an inlet port are in fluid communication with the interior space. The assembly includes a first circulator for circulating a first fluid between the outlet port and the inlet port, and a second circulator for circulating a second fluid along an exterior surface of the semi-permeable membrane. The second circulator includes a fluid duct attached to or integrated within the housing. The fluid duct is isolated from the interior space and is porous to provide fluid access to an exterior surface of the semi-permeable membrane. The semi-permeable membrane forms a barrier allowing exchange of compounds across the membrane.

    Abstract: A method is disclosed for the generation of hydrogen and oxygen from a liquid feed stream comprising water. The method includes passing an electric current through an aqueous electrolyte solution. Water is fed to the aqueous electrolyte solution by forward osmosis, wherein the aqueous electrolyte solution is brought into contact with a first side of a forward osmosis membrane and the liquid feed stream comprising water is brought into contact with a second side of the forward osmosis membrane. Water permeates through the forward osmosis membrane from the second side to the first side by a difference in osmotic pressure between the liquid feed stream and the aqueous electrolyte solution. Further, a device is disclosed for carrying out the above method.

    Abstract: A method and system for performing characterization of one or more materials. One or more materials are scanned by means of a sensory system including an X-ray sensor configured to perform multi-energy imaging for obtaining at least a lower-energy X-ray image and a higher-energy X-ray image. Images obtained by means of the sensory system are segmented, and for each segmented object, data indicative of an area density and data indicative of an atom number by analysis of the lower-energy X-ray image and the higher-energy X-ray image, and data indicative of the area density and atom number is determined by means of a calibrated model. Data indicative of a mass is calculated based on the data indicative of the area density and the data indicative of the area of each of the segmented objects. The data indicative of the atom number is provided as input to a trained neural network, wherein the trained neural network is configured to label each segmented object, and wherein the data indicative of the mass is coupled to each of the labeled segmented objects.
