摘要:
A method of applying dopant to a substrate includes selecting at least one desired property of the substrate which should vary across the substrate, and variably applying at least one dopant solution to the substrate to provide the desired property which varies across the substrate.
摘要:
A method for forming a fuel cell component includes depositing a hydroxide or oxyhydroxide form of the component, and hydrothermally dehydrating the hydroxide or oxyhydroxide form of the component, wherein the hydrothermally dehydrating of the component establishes the grain structure of the component.
摘要:
Nano-scale structures are provided wherein nano-structures are formed on a substrate surface and a base material is applied between the nano-structures.
摘要:
A piezoelectric actuator is formed by forming first and second electrodes on a substrate, and depositing a material on the substrate and between side surfaces of adjacent first and second electrodes to form a thin film sheet within which the first and the second electrodes extend from a first surface of the thin film sheet towards a second surface of the thin film sheet opposite the first surface. The second electrode is interdigitated in relation to the first electrode. The side surfaces of the first and the second electrodes are at least substantially perpendicular to the substrate. The thin film sheet is to physically deform in response to an electric field induced within the thin film sheet via application of a voltage across the first and the second electrodes.
摘要:
In an embodiment, a method of compensating for capacitance change in a piezoelectric element of a fluid ejection device includes sensing a current driving a piezoelectric element, determining from the current that capacitance of the piezoelectric element has changed, and altering a rise time of the current driving the piezoelectric element to compensate for the changed capacitance.
摘要:
A fluid ejection device includes a firing chamber having a chamber floor with an orifice opposite the chamber floor and a heating element partially covering the chamber floor, a region of the chamber floor being contoured to define a cavity extending into the chamber floor.
摘要:
A method of depositing nano-dots on a substrate includes forming a template on the base, the template defining nano-pores, at least partially filling the nano-pores with a pillar material to define nano-pillars, depositing a dot material on the nano-pillars to define nano-dots on the nano-pillars, and contact printing the substrate with the array of nano-dots.
摘要:
A ring-type heating resistor for a thermal fluid-ejection mechanism includes resistive segments and conductive segments. The resistive segments are rectangular in shape. The resistive segments are separated from one another. The conductive segments are interleaved in relation to the resistive segments such that each conductive segment electrically connects two of the resistive segments. The resistive segments and the conductive segments together form a pseudo-ring that approximates a true ring.
