The invention relates to a hernia-repair mesh, coated with thin layers of nanocomposite materials consisting of polyethylene oxide polymer PEO and carbon nanotubes CNT and to a process for making the same. According to the invention, the mesh consists of a commercial macroporous monofilament net made of polypropylene or polyester, with the pore size > 1 mm, coated, at the exterior, with a continuous homogenous thin adherent nanocomposite film based on polyethylene oxide and carbon nanotubes. The claimed process has the following stages: a.
The invention relates to a method of electromagnetic protection of electronic circuits using metal-coated plastic cases. According to the invention, the method consists in coating the case walls with conductive layers, as follows: an at least 600 nm-thick Cu layer and an at least 400 nm-thick Ni layer, said layers having the role of reflecting and absorbing the electromagnetic radiation, the thermionic vacuum arc method being used for deposition.
The invention relates to a process for obtaining thin films with a content of amorphous stoichiometric and non-stoichiometric silicon nitride, in high vacuum conditions, on flexible temperature-sensitive substrates to be used in microelectronics and for generating energy, as anti-reflective protective layer.
The invention relates to a deposition head for continuous coaxial deposition with in-situ synthesis of nanoparticles, which makes possible nanopowder alloying upon deposition of micrometric powder of SiC or carbon nanoparticles or carbon nanotubes, using high power laser, with application in applied engineering, information engineering, industrial engineering, mechatronic engineering, nano engineering, system engineering and the like.
