An adhesive system (100) for attachment to a contact surface (122) of an object (120) comprises a backing (110), carbon nanotubes (130), charged nanoparticles (150), and an electrical source (160). The carbon nanotubes (130) each have a first end region (132) and a second end region (134), opposite the first end region (132). Each of the charged nanoparticles (150) is coupled to the second end region (134) of at least one of the carbon nanotubes (130). The electrical source (160) is configured to selectively electrically charge the backing (110) to cause an electrical repulsion force between the backing (110) and the charged nanoparticles (150). The first end region (132) of each of the carbon nanotubes (130) is coupled to the backing (110). The second end region (134) of each of a number of the carbon nanotubes (130) is coupled to none of the charged nanoparticles (150).

Method and device for delamination/dismantling of multi-layer systems SM comprising several layers including at least one organic layer, wherein the layers are separated by interfaces, characterized in that it comprises at least the following steps: Mixing the multilayer system with a fluid composed of at least one gas having the particularity of causing the swelling of at least one of the layers and one or more non-reactive liquids having the particularity of allowing the separation of each layer unitarily or of subsets of layers composing the multilayer system without degradation of the constituents of the layers, the gas/liquid fluid being raised in temperature and pressure, Recovering separately at least one or more layers or a subset of undegraded layers.

A method of recycling a solar cell module includes an enclosing layer that encloses a solar cell therein, a light-receiving surface layer laminated on one surface of the enclosing layer, and a back sheet laminated on the other surface of the enclosing layer, the method including: a first removing step of mechanically removing the back sheet; a second removing step of mechanically removing from a side on which the back sheet is removed the entire solar cell and the enclosing layer to such a depth that a part of the enclosing layer having a predetermined thickness remains on the light-receiving surface layer, after the first removing step; and a third removing step of removing the part of the enclosing layer remaining on the light-receiving surface layer by immersion in a solution that causes swelling of the enclosing layer, after the second removing step, thereby improving an overall efficiency.
