Abstract: A method for casting an object includes additively producing, by a casting system, multiple production layers, one currently-produced production layer after the other. For each currently-produced production layer, the method includes forming, by a mold system of the casting system, one or more mold-layers, providing, by a replaceable material provision system of the casting system, one or more replaceable material layers; and forming, by a molten metal processing of the casting system, one or more current object regions of the currently-produced production layer by providing molten metal that replaces the one or more replaceable material layers.

Abstract: A system and a method are provided for utilizing excess heat generated by an industrial process, in an electrochemical process. The system comprising: an electrochemical reactor for carrying out an electrochemical reaction, wherein the electrochemical reaction requires a pre-defined minimal temperature to be carried out; means operative to receive a gaseous feed stream generated in the industrial process and being at an elevated temperature; an inlet for introducing one or more chemical reactants to the electrochemical reactor; wherein the system is characterized in that the gaseous feed stream temperature is not constant and for at least part of the time, the temperature of the gaseous feed stream received by the system is lower than the required pre-defined minimal temperature.

Abstract: A reactor is provided which comprises: a plurality of reaction units located within a reaction zone, each of the reaction units being adapted to enable carrying out a chemical reaction of one or more raw gases (e.g. at least one of CO2 and H20); ingress means to allow introduction of the one or more raw gases into the reaction zone and to allow distributing the incoming gas to the plurality of reaction units; egress means to allow exit of reaction products from the reaction zone; and a heating system. The reaction units extend essentially along a longitudinal axis of the reaction zone and are arranged in a spaced-apart relationship along a lateral axis of the reaction zone. The heating system comprises a plurality of heating sources extending along the reaction zone, thereby providing at least a part of the energy to carry out the reaction process within the reaction units.

Abstract: Alignment of layers during manufacture of a multi-layer sample is controlled by applying optical measurements to a measurement site in the sample. The measurement site includes two diffractive structures located one above the other in two different layers, respectively. The optical measurements include at least two measurements with different polarization states of incident light, each measurement including illuminating the measurement site so as to illuminate one of the diffractive structures through the other. The diffraction properties of the measurement site are indicative of a lateral shift between the diffractive structures. The diffraction properties detected are analyzed for the different polarization states of the incident light to determine an existing lateral shift between the layers.
