Abstract: The instant invention provides microcapillary films containing phase change materials. The microcapillary film containing phase change materials according to the present invention has a first end and a second end, and comprises: (a) a matrix comprising a thermoplastic material, (b) at least one or more channels disposed in parallel in said matrix from the first end to the second end of said microcapillary film, wherein said one or more channels are at least 5 ?m apart from each other, wherein said one or more channels have a diameter of at least 5 ?m; and (c) at least one or more phase change materials disposed in said one or more channels; wherein said microcapillary film has a thickness in the range of from 10 ?m to 2000 ?m.

Abstract: A device is proposed for the contactless grasping and holding of an object from a direction directed at least partially in the direction of the force of gravity, using a holding element situated counter to the direction of the force of gravity, at least partially above the object and at a distance from the latter, which to the greatest extent possible avoids the carrying off or migrating of particles that are possibly present. According to the present invention this is achieved in that the holding element is designed as a vibrating holding element for generating levitation waves.

Abstract: A device is proposed for the contactless grasping and holding of an object (1) from a direction (z) directed at least partially in the direction (z) of the force of gravity (F), using a holding element (3) situated counter to the direction (z) of the force of gravity (F), at least partially above the object (1) and at a distance from the latter, which to the greatest extent possible avoids the carrying off or migrating of particles that are possibly present. According to the present invention this is achieved in that the holding element (3) is designed as a vibrating holding element (3) for generating levitation waves.
