    Abstract: A composite coating and method for preparing the composite coating on titanium implants for tissue culture and tissue engineering is provided. The implants are characterized in that the titanium component to be coated is placed in a aqueous solution containing calcium cations, phosphate anions, and dispersed carbon nanoparticles (such as single layer graphene oxide or graphene oxide) in an amount of about 0.05%-1.50% by weight relative to the total weight of aqueous solution. The dimensions of the dispersed graphene oxide should be around, but not limited to, 300-800 nm (X-Y), while their thickness is about 0.7-1.2 nm. The aqueous solution with carbon nanoparticles is prepared by mixing for at least 72 h in temperature in range 20-35° C. and sonicated before electrodeposition process. In the prepared solution is further placed titanium which acts as cathode element (may be the implant), and anode which can be, for example, a platinum rod. Between the cathode and anode is set a potential from ?1.3V to ?1.

  • Patent number: 9374915
    Abstract: The invention relates to a backplane configuration for use in an electronic crate system, said backplane configuration comprising a first-type backplane and a second-type backplane; wherein the first-type backplane is coupled to the second-type backplane by mechanical connection means; wherein the first-type backplane and the second-type backplane are spatially separated from each other by a distance which is sufficient such that electromagnetic interferences between the first-type backplane and the second-type backplane are eliminated or at least minimized; and wherein the first-type backplane is adapted to be electrically coupled with at least one first-type module, and the second-type backplane is adapted to be electrically coupled with at least one second-type module.
