The invention relates to a method and a device for producing large-volume container trays of plastic. A tubular preform is guided over a mold frame which is facing two blow molds. During the closure of the blow molds, an encircling flange is formed on the outer edge of the container trays. After blow molding, the container trays are cut free from the mold frame along said mold frame.

Provided are a nanofiber-nanowire composite and a method for producing the same. The method includes preparing a nanoparticle using a dipolar solvent, producing a nanofiber-nanoparticle composite in an electrospinning synthesis solution including the nanoparticle through electrospinning, and growing a nanowire from the nanoparticle by hydrothermally synthesizing a dried nanofiber-nanoparticle composite.

Systems and methods are provided for fabricating carbon nanostructures by low voltage near-field electromechanical spinning (LV-NFEMS). Processes described herein can produce 2-5 nm carbon nanowires with ultrahigh electrical conductivity using top-down and controlled reductive techniques from a polymer. Configurations are also provided to allow for deposition control and fiber elongation/alignment. One embodiment uses a low voltage near-field electromechanical spinning process to produce a polymer fiber from a polymer solution. Another embodiment of the method uses pyrolysis to convert the produced polymer fiber into a 2-5 nm carbon nanowire. System configurations provide advancements in polymer droplet control and control of a sustained jet of polymer solution with the use low voltages. Systems and processes described herein can include use of an array of polymer precursor nanofibers suspended onto a silicon substrate and converted to carbon nanowires. In another embodiment, ultra-thin carbon fibers can be integrated onto a carbon electrode scaffold.

The present invention includes an insulating panel for building structures, a printing device for making an insulating panel for building structures, and a method for the manufacturing of an insulating panel for building structures. The insulating panel resulting from the printing device comprises a multi-layered basalt sandwich wall that is made of external layers on either side of a middle layer. The external layers comprise a load-bearing coating made from basalt, and the middle layer comprises a heat insulating material made from basalt (basalt wool or foamed basalt). As a result, a specific sandwich-panel is manufactured from one local raw material (basalt), which possesses high mechanical and heat insulating properties. Such technology can be used for erecting comfortable buildings for colonists for long term use even under severe climatic conditions of solar system planets and satellites where appropriate raw materials exist.
