  • Ambient temperature based flow rates
    Patent number: 10112385
    Abstract: Ambient temperature based flow rates can in an example include a setting a flow rate of ink to a printhead mounted in a carriage based on an ambient temperature associated with the printhead, measuring a flow rate of ink to the printhead, and causing a decrease in a velocity of the carriage in response to the flow rate of ink satisfying the threshold flow rate.
    Type: Grant

  • Graphene solutions
    Patent number: 9120675
    Abstract: The present invention relates to a method of solubilizing graphite and applications thereof, including the manufacture of composites and the purification of graphene. The method of the invention is characterized in that it comprises the following steps carried out under inert atmosphere: a) reduction of graphite by an alkali metal to lead to a graphite intercalation compound; and b) exposure of the graphite intercalation compound to a polar aprotic solvent to lead to a reduced graphene solution. The present invention relates more particularly to graphene solutions and graphene planes obtained through said method, as well as uses of such graphene solutions and planes.
