    摘要: The present invention refers to a porous composite material, wherein at least one interdispersed biopolymer is present, with a calcium-phosphate mineral component comprising from 50 w/% to 95 w/% of α-tricalcium phosphate (α-TCP, α-Ca3(PO4)2) and from 5 w/% to 50 w/% of octacalcium phosphate (OCP, Ca8H2(PO4)6—5H2O), to the total weight of the mineral component. Such combination of α-TCP and OCP allows an in vivo faster resorption rate and thereby a faster formation of new bone tissue having a low cristallinity mineral component with nanocrystal structure, features very similar to those of biological apatites. This porous composite material may find application as bone and/or osteal-chart ilagineous substitute (scaffold) and in producing tissue engineering devices.

    摘要: Sterilization method using plasma for sterilizing objects, wherein it is provided to introduce the objects to be sterilized into a sterilization chamber (13) and covey toward the latter a flow of air coming from a feed pipe (17) on which a plasma generator device (30) is disposed able to generate one or more gaseous compounds comprising a mixture of reactive oxygen species (ROS) and of reactive nitrogen species (RNS) so that the air is the carrier fluid which conveys the gaseous compounds toward the sterilization chamber (13); the method also provides to control the electric power used to produce the plasma as a function of the composition and/or the quantity of reactive species present in the sterilization chamber (13).
