  • Patent number: 10519298
    Abstract: Core particles produced in situ or introduced as preformed core particles are coated with a layer of carbon. Non-carbon as well as some carbon-based core materials can be utilized. The resulting carbon coated particles can find applications in rubber products, for instance as reinforcement for tire components.

  • Patent number: 9975270
    Abstract: Method for manufacturing an aerogel-containing composite, said method comprising the steps of: providing fibers, at least some of which are first fibers, such as mineral fibers, polymer fibers, cellulose fibers, or other types of fibers, in an amount of from 3 to 80 wt % of the total weight of starting materials, providing an aerogel particulate material in an amount of from 10 to 75 wt % of the total weight of starting materials, providing a binder in an amount of from 1 to 30 wt % of the total weight of starting materials, suspending the fibers in a primary air flow and suspending the aerogel particulate material in the primary air flow, thereby mixing the suspended aerogel particulate material with the suspended fibers, mixing the binder with the fibers and/or aerogel particulate material before, during or after mixing of the fibers with the aerogel particulate material, collecting the mixture of fibers, aerogel particulate material and binder and pressing and curing the mixture to provide a consolidated c

  • Patent number: 7332264
    Abstract: The present invention provides a mesoporous material comprising at least one region of mesoporous material patterned at a lithographic scale. The present invention also provides a method for forming a patterned mesoporous material comprising: coating a sol on a substrate to form a film, the sol comprising: at least one photoactivator generator, at least one material capable of being sol-gel processed; and exposing the film to light to form a patterned mesoporous material.
