Abstract: Self-assembling materials, such as block copolymers, are used as mandrels for pitch multiplication. The copolymers are deposited over a substrate and directed to self-assemble into a desired pattern. One of the blocks forming the block copolymers is selectively removed. The remaining blocks are used as mandrels for pitch multiplication. Spacer material is blanket deposited over the blocks. The spacer material is subjected to a spacer etch to form spacers on sidewalls of the mandrels. The mandrels are selectively removed to leave free-standing spacers. The spacers may be used as pitch-multiplied mask features to define a pattern in an underlying substrate.

The mineral layer may comprise a homogeneous layer of hydroxyapatite or a thin veneer of hydroxyapatite on a layer of amorphous calcium phosphate. The simulated enamel is then optionally treated with an oral care product and subjected to an acid challenge. The amount of mineral layer remaining after the acid challenge illustrates the effectiveness or non-effectiveness of the oral care product at preventing dental erosion.

Abstract: The aim of the invention is to produce a textile surface (1), one side of which exhibits hydrophilic properties and the other side hydrophobic properties, whose overall cross-section is hydrophilic. To achieve this, a paste (11) consisting of a viscous emulsion or dispersion of paraffin, polysiloxane and/or fluorine compounds is applied to one side. The layer that has been formed by the first paste (11) is then stabilized by means of a drying process (4) and a second paste (12), consisting of a hydrophilic polymer is subsequently applied to the other side of the textile surface (1), said paste being stabilized by an additional drying process (5). Said steps provide a textile surface (1), which can be produced simply and cost-effectively, is extremely comfortable to wear and which ensures that moisture is immediately absorbed on the hydrophilic side, dispersed over a large area and rapidly removed, whereas the hydrophobic side of said textile surface (1) repels water.
