Abstract: A catalytic composition is built up from a ceramic material including a catalytic material and a first inorganic binder and a second inorganic binder and a catalytic structure made thereof. Preferably, the structure is made by a colloidal ceramic shaping technique. The structure is usable for catalytic or ion exchange applications as well. It is demonstrated that the catalytic structures have excellent mechanical, physicochemical and catalytic properties.

Abstract: A method and system for manufacturing a three-dimensional porous structure. Filaments are deposited in a predetermined interconnected arrangement in a plurality of stacked layers for forming a porous structure with interconnected pores. A pressure value indicative of a pressure being applied on the build material in the build material reservoir of a nozzle used for deposition is monitored during deposition of the filaments. The processing unit is configured to adjust at least one extrusion parameter in order to compensate for the irregular rising and/or falling of the pressure value.

Abstract: A method and system for manufacturing one or more three-dimensional porous structures (10). Filaments (2) are deposited on a support in a predetermined interconnected arrangement in a plurality of stacked layers (11) for forming one or more porous structure with interconnected pores (15). A nozzle head (30) with a plurality of nozzles (20) is used for depositing filaments. The plurality of nozzles are spaced apart from each other with a predetermined spacing therebetween. Each nozzle has an opening area through which filaments are dispensed as the nozzle head is moved relative to the support. Multiple 3D porous structures are manufactured in parallel, using a subset of nozzles for each porous structure, each subset of nozzles including at least one nozzle. Neighboring subsets of nozzles are distanced in order to provide a working area on which the relevant porous structure of the plurality of porous structures is manufactured.

Abstract: The present disclosure relates to a method for producing lanthanide doped layered double hydroxides (Ln-doped LDHs). The method includes the steps of preparing a carbonate free alkaline solution; preparing a solution of metal salts comprising a salt of a lanthanide; co-precipitating the alkaline solution and the solution of metal salts to form a mixture and Ln-doped LDH precipitate wherein the pH of the mixture is maintained at a constant value; aging the precipitate; and separating the precipitate from the solution. The alkaline solution is an aqueous ammonia solution. The present disclosure is also related to lanthanide-doped layered double hydroxides (La-doped LDHs) obtainable by such a method, as well as to the use of the lanthanide-doped layered double hydroxides obtainable by such a method.

Abstract: A radionuclide separating system for separating a 213Bi daughter radionuclide from a 225Ac parent radionuclide, the radionuclide separating system comprising: an inlet for loading a liquid solution comprising the 225Ac parent radionuclide onto a column; the column comprising a sorbent material wherein the sorbent material is capable of interacting with the 225Ac parent radionuclide and 213Bi daughter radionuclide so as to allow selective desorption of the 225Ac parent radionuclide and/or the 213Bi daughter radionuclide at a different moment in time; and an outlet for selectively obtaining the 213Bi daughter radionuclide based on the selective desorption of the 225Ac parent radionuclide and the 213Bi daughter radionuclide, wherein the sorbent material is a carbon-based sorbent material.

Abstract: A surgical implant may include a porous structure with interconnected pores for ingrowth of bone into the porous structure. The porous structure has an arrangement of fibres which are attached to one another, the fibres being arranged in stacked layers. The porous structure has a surface including different regions having different porosities. A method of making the above surgical implant is also described.
