  • Methods and apparatus providing a substrate having a coating with an elastic modulus gradient
    Patent number: 9776913
    Abstract: Methods and apparatus are provide for: a substrate having first and second opposing surfaces, and an elastic modulus; and layer(s) having a thickness between first and second opposing surfaces thereof, the first surface of the layer contacting the second surface of the substrate, forming an interface. The layer may exhibit one or more of: a first elastic modulus proximate to the first surface thereof and a second elastic modulus proximate to the second surface thereof, the second elastic modulus being substantially higher than the elastic modulus value, the first elastic modulus being lower than the elastic modulus of the substrate, the second elastic modulus being higher than the elastic modulus of the substrate, and the layer exhibiting an increasing elastic modulus gradient through the thickness thereof from the first elastic modulus to the second elastic modulus.
    Type: Grant
    Filed: July 29, 2014
    Date of Patent: October 3, 2017
    Assignee: Corning Incorporated
    Inventors: Zhanjun Gao, Guangli Hu, Ralph Edward Truitt

  • Flow-through substrates and methods for making and using them
    Patent number: 8404026
    Abstract: Flow-through substrates, such as honeycombs, comprising certain zeolites. The flow-through substrates may be used, for example, in the removal of a heavy metal from a fluid such as a gas stream.
