  • Patent number: 8722073
    Abstract: The present invention relates to a bone cement precursor system that is presented in the form of two shelf-stable pastes which have been terminally sterilized and are held in separate containers during product transport and storage. When the product is used during surgery, these pastes inject to a site of application through a static mixing device by the action of applied injection force. When the two pastes are mixed, they start to react to each other while injecting out. The resulting composition is highly biocompatible, osteoconductive, injectable, rapid setting and bioresorbable, and is useful in connection with bone repair procedures, for example, in the craniomaxillofacial, trauma and orthopedic areas.

  • Publication number: 20120119420
    Abstract: A method of synthesising a nano metric composite which has a core and shell structure includes preparing isometric metal oxide cores with an average diameter of less than 100 nm by a growth process via a liquid route. A double surfactant method is used which includes a first surfactant to obtain mono dispersal of the metal oxide cores and then a second surfactant to prepare the surface of the metal oxide cores, thereafter grafting a shell on each core.
