Abstract: The invention relates to a carbon-containing nanomaterial comprising, in particular made up as, a network of carbon wall structures which enclose open or closed voids which has a density which can be as low as 0.2 mg per cm3 or lower. The nanomaterial of the invention is made up as a network of carbon wall structures. The carbon wall structures can be tubular, rod-like or in the form of webs or the like which have varying thickness and thus form a network structure, in particular a three-dimensional network structure constructed in the manner of a sponge.

Abstract: A method and a device for processing a light-polymerizable material (5, 55) for building up an object (27) in layers, using a lithography based generative manufacture having a construction platform (12) for building up the object (27), a projecting exposure unit (10, 60) that can be controlled for locally selected exposing of a surface on the construction platform (12, 62) to an intensity pattern having a prescribed shape, and a control unit (11, 61) prepared for polymerizing overlapping layers (28) on the construction platform (12, 62) in successive exposure steps, each having a prescribed geometry, by controlling the projecting exposure unit (10, 60), in order to thus successively build up the object (27) in the desired shape, said shape resulting from the sequence of layer geometries.
