A method of producing a microtube is provided. The method comprising co-electrospinning two polymeric solutions through co-axial capillaries to thereby produce the microtube, wherein a first polymeric solution of the two polymeric solutions is for forming a shell of the microtube and a second polymeric solution of the two polymeric solutions is for forming a coat over an internal surface of the shell, the first polymeric solution is selected solidifying faster than the second polymeric solution and a solvent of the second polymeric solution is selected incapable of dissolving the first polymeric solution. Also provided are electrospun microtubes.

The present invention relates to a high speed transmission cable (100) that includes a first inner conductor (110) and a dielectric film (120) that is concentrically arranged around at least a portion of the first conductor (110). The dielectric film (120) has a base layer (122) including a plurality of first protrusions (124) and second protrusions (126) formed on a first major surface of the base layer (122), wherein the first protrusions (124) and the second protrusions (126) are different from one another. The first protrusions (124) of the dielectric film (120) are disposed between the first inner conductor (110) and the base layer (122), the first protrusions (124) forming an insulating envelope around the first inner conductor (110).

An inverter surge-resistant insulated wire comprising a conductor and an enamel resin-insulating laminate that has a foamed region including cells and a non-foamed region including no cells on at least one surface of the foamed region on the conductor, wherein the foamed region is configured such that a non-cell layer including no cells has cell layers formed of closed cells on both surface sides of the non-cell layer, a thickness of the non-cell layer is larger than a thickness of a partition wall among the closed cells, and 5 to 60% of a thickness of the foamed region, and at least 10 the cell layer in the foamed region is formed of a thermosetting resin; an inverter surge-resistant insulated wire having a conductor and the enamel resin-insulating laminate; and electric/electronic equipment.

A multi-walled titanium-based nanotube array containing metal or non-metal dopants is formed, in which the dopants are in the form of ions, compounds, clusters and particles located on at least one of a surface, inter-wall space and core of the nanotube. The structure can include multiple dopants, in the form of metal or non-metal ions, compounds, clusters or particles. The dopants can be located on one or more of on the surface of the nanotube, the inter-wall space (interlayer) of the nanotube and the core of the nanotube. The nanotubes may be formed by providing a titanium precursor, converting the titanium precursor into titanium-based layered materials to form titanium-based nanosheets, and transforming the titanium-based nanosheets to multi-walled titanium-based nanotubes.
