Abstract: An ink composition for additive manufacturing comprises at least a first phase, the first phase being a liquid phase, and inorganic particles being distributed in the first phase. The inorganic particles are redox active. The first phase furthermore comprises at least one organic processing additive. In a method of additive manufacturing a structure for use in a thermochemical fuel production process and/or in a heat transfer application, said ink composition is deposited so as to form a precursor structure, and said precursor structure is subjected to at least one thermal treatment so as to form the structure for use in the thermochemical fuel production process and/or in the heat transfer application.

Abstract: An additive for a bituminous binder respectively a bituminous composite material, able to reduce bituminous binder respectively bituminous composite material viscosity when an alternating magnetic field is applied, in particular for healing pavement cracks and in-depth micro-cracks in asphalt, wherein the additive comprises an amount of magnetic iron oxide particles should be improved, in order to reach bituminous composite material respectively a bituminous binder which can be melted in a faster and simplified way, in particular usable for crack healing of asphalt structures on site. This is reached by forming the additive comprising at least a part of magnetic iron oxide nanoparticles with average sizes between 1 nm and 300 nm coated with a fatty acid.

Abstract: A method for making a composite material with non-spherical reinforcing particles embedded in a matrix, is disclosed. In this method, in a first step magnetic and/or superparamagnetic nanoparticles are attached to the non-spherical reinforcing particles, in a second step the resulting reinforcing particles are introduced into a liquid matrix material and/or a liquid matrix-precursor material, and in a third step the material of the matrix is solidified and/or polymerized and/or cross-linked. In accordance with the proposed invention prior to and/or during solidification and/or polymerization and/or cross-linking of the matrix material or the matrix precursor material, respectively, a magnetic field is applied so as to align the reinforcing particles in the matrix and this alignment is fixed in the matrix during and after the third step, wherein the non-spherical reinforcing particles preferably have a length (l) in one dimension of at least 0.

Abstract: A method of producing a rigid catalytically active porous ceramic is disclosed. Catalyst particles comprising a catalytically active material or a precursor thereof are mixed with a chemical additive, a ceramic binder, a carrier liquid and, optionally, substantially inert carrier particles to obtain a slurry having a gel-or paste-like consistency. The slurry may be transported to a substrate, e.g., by printing, or to a reactor cavity by a suitable flow method. The slurry is then heated to substantially evaporate said carrier liquid to obtain a rigid, catalytically active porous ceramic in situ. A catalyst obtainable by such a method and the use of such a catalyst are also disclosed.

Abstract: Described is a method to prepare wet foams exhibiting long-term stability wherein colloidal particles are used to stabilize the gas-liquid interface, said particles being initially inherently partially lyophobic particles or partially lyophobized particles having mean particle sizes from 1 nm to 20 ?m. In one aspect, the partially lyophobized particles are prepared in-situ by treating initially hydrophilic particles with amphiphilic molecules of specific solubility in the liquid phase of the suspension.
