The present invention relates to processes for producing fiber cement products as well as to the fiber cement products obtainable therewith. More specifically, the present invention relates to fiber cement products that are suitable for being subjected to ink-jet printing, which fiber cement products at least comprise on their outer surface one or more cured layers of a first coating composition, which at least comprises a binder and a pigment and which is characterized by a pigment volume concentration of higher than about 40%. The invention further provides processes for producing such fiber cement products. Moreover, the present invention provides processes for producing ink-jet printed fiber cement products and ink jet printed fiber cement products obtainable therewith. The present invention further relates to various uses of these fiber cement products, in particular as building materials.

A method of forming a feature on an article includes applying a powder material stock to a surface of an article, the powder material stock being capable of being transformed into a solid feature by the application of energy; applying energy to a portion of the powder material stock within a footprint of a feature to form the feature within the footprint; and removing excess powder material stock from the surface of the article. A coated article is also disclosed.

A knife may include a blade having a first side face and a second side face. The blade may include zirconia as a main component, and include a cutting region including at least a ridge portion between the first side face and the second side face. When a portion including the cutting region in the first side face is referred to as a first cutting face, and a portion including the cutting region in the second side face is referred to as a second cutting face, the proportion of cubic crystals of zirconia in the first cutting face may be larger than the proportion of cubic crystals of zirconia in the second cutting face.

A method for etching a light absorbing material permits directly writing a pattern of etching of silicon nitride and other light absorbing materials, without the need of a lithographic mask, and allows the creation of etched features of less than one micron in size. The method can be used for etching deposited silicon nitride films, freestanding silicon nitride membranes, and other light absorbing materials, with control over the thickness achieved by optical feedback. The etching is promoted by solvents including electron donor species, such as chloride ions. The method provides the ability to etch silicon nitride and other light absorbing materials, with fine spatial and etch rate control, in mild conditions, including in a biocompatible environment. The method can be used to create nanopores and nanopore arrays.
