Recording medium
A recording medium is provided, such as paper, secured by magnetic microwires. The recording medium comprises: a pulp structure formed by pulp fibers, said pulp structure carrying microwires having a metal core of a predetermined material composition, and an insulating layer coating on said metal core; and at least one coating layer on at least one side of said pulp structure. The pulp structure is a single-layer structure with the microwires fully embedded in said single layer, the microwires having cross-sectional dimensions approximately equal to cross-sectional dimensions of the pulp fibers.

Method for coating a fibrous web, and a surface coated fibrous web
A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.

NATURAL FIBER REINFORCED COMPOSITE PANEL AND METHOD
A method of making a natural fiber composite panel includes extracting bamboo fibers from bamboo and embedding the extracted bamboo fibers in a polymer matrix material. The bamboo includes bamboo fibers and lignin, and the step of extracting includes mechanically scraping the bamboo fibers to remove at least some of the lignin. In some cases, the bamboo is steamed, soaked in water, soaked in an acidic solution and/or soaked in an alkaline solution before mechanical scraping.
