  • Patent number: 10563080
    Abstract: Copper inks are provided that include a plurality of core-shell nanostructures, with each nanostructure including a copper core and a barrier metal shell, a diameter of less than about 500 nm, and a distinct boundary between the copper core and the barrier metal shell. Methods of forming a copper ink are further provided and include an initial step of synthesizing an amount of copper nanoparticles in an aqueous solution. An amount of a barrier metal is then added to the copper nanoparticles to form a dispersion of the barrier metal and the copper nanoparticles, and a reducing agent is subsequently added to the dispersion to produce a copper ink comprising core-shell nanostructures having a copper core and a barrier metal shell. Copper films are then formed by applying that copper ink to a substrate and sintering the copper ink.

  • Patent number: 10548684
    Abstract: The present disclosure relates generally to dry inks for use in marking the eye prior to surgery and methods of applying the same to eye marking devices. Such inks can include various accepted inks for use on the eye that can be applied to a marking device using relatively fast-evaporating solvents. In this manner, the remaining ink composition can be precisely placed on the eye marking device, and desirably transfer to the marking surface of the eye without dissolving on the journey through the various membranes above the marking surface. Application methods may include use of charged ink particles that may be advantageously manipulated using magnetic fields to even more precisely place the dry ink on a marking device.
