The present invention relates to a method for preparing an activated lignin composition. In addition, the present invention also relates to a method for further processing the thus activated lignin composition in a method for preparing a lignin-phenol formaldehyde resin. Such a lignin-phenol formaldehyde resin can be used in the manufacturing of laminates by replacing the traditional synthetic phenol formaldehyde resin.

A personal electronic device case, and method for making such personal electronic device case, created by a method of bonding a resin-type material to a selected material otherwise unsuitable for protection of a personal electronic device, and carving the resulting composition into a desired shape of personal electronic device case. The resulting phone case is both aesthetically pleasing and offers improved protection for the personal electronic device.

A composite material includes a plurality of reinforcements arranged in a plurality of layers. Each reinforcement comprises a tapered shape that allows the reinforcements of a particular layer to nest with reinforcements of an adjacent layer. The composite material further includes an adhesive that is at least partially between the layers of reinforcements.

A reinforcing structure made of a sheet-like cellular base material which comprises material attenuations (3) in a distribution over its area in a view from above, wherein the material attenuations sub-divide the base material into a multitude of material islands (1R; 1T) which are delineated from each other by the material attenuations (3) but are still connected to each other, wherein (a) the material islands (1R; 1T) are convex base polygons in a view from above; (b) a respective plurality of the material islands (1R; 1T) jointly form a convex and preferably regular compound polygon (1H) in a view from above; and (c) the compound polygons (1H) differ, in their number of corners and/or in a ratio of the lengths of their sides, from the base polygons which form the material islands (1R; 1T).
