摘要:
The present invention is directed to nanoscale fabrication of nano-materials with application in electronics, energy conversion, bio-sensing and others. Specifically, the invention is directed to arbitrary, that is periodic and non-periodic, assembly of nano-objects on I D and 2D arrays. The present invention utilizes self-organization properties of nanoscale bio-encoded building blocks, programmability of biomolecular interactions, and simple processing techniques for providing arbitrary by-design fabrication capability. Specifically, the present invention utilizes double stranded DNA attached to a surface and intercalating PNA-DNA hybrids attached to nano-objects to bind the nano-objects to the dsDNA in a site specific manner. The present invention allows for an integration of a large number of nano-components in unified well-defined systems. Accordingly, the present invention is applicable for fabrication of I D and 2D structures of various by-design placements of nano-objects of multiple types, including metal, semiconducting and organic nano-objects.

The present invention concerns a method for forge welding of tubes, rods, bolts or other axial symmetrical profiles. According to the methods the profile ends are formed by plastic deformation and/or machine cutting processes, such that they obtain a reduced cross section/thickness, the profile ends are locally heated electromagnetically by induction and/or direct high frequency resistance heating and profile ends are then pressed together. The forming step comprises given one of the profile ends a double arched shape. Preferably the other profile end is given a convex shape.

The Invention concerns an arrangement for ventilation in buildings comprising air gap forming sealing elements, wherein the arrangement includes angular profiles of elongated mounting elements for mounting to the beam surfaces, roof trusses, joists or similar, between which air gaps are to be provided and a membrane that attaches to the mounting elements of the angular profiles in such a way that they form an essentially airtight surface suitable for restricting an air gap. Further, the invention concerns a procedure for the provision of an air gap in existing buildings, where you attach the angular profiles to the two side walls facing an aperture, after which air gap forming elements is fastened to angular profiles, such that a membrane between the side walls is formed.
