Abstract: A bus capacitor includes: multiple capacitor layers stacked along a thickness direction of the bus capacitor, a dielectric being filled between two adjacent capacitor layers; the multiple capacitor layers including multiple positive capacitor layers and multiple negative capacitor layers; a first hole extending along the thickness direction, the first hole running through the multiple positive capacitor layers, a first conductive member disposed in the first hole, and the first conductive member being in contact with the multiple positive capacitor layers to electrically connect the multiple positive capacitor layers with each other; a second hole extending along the thickness direction, the second hole running through the multiple negative capacitor layers, a second conductive member disposed in the second hole, and the second conductive member being in contact with the multiple negative capacitor layers to electrically connect the multiple negative capacitor layers with each other.

Abstract: A system and method for using gradient nanotopography to increase mammalian cell attachment and cell confinement on surfaces. A surface platform consisting of a thin film of gold possessing a gradient of topography on the surface and self-assembled monolayers of alkanethiols presenting desired functional groups is formed. A gradient in the chemical properties is induced in the terminal groups of the monolayer because of the continuous increase in the surface area and the anisotropy of gold film structure. The gradient nanotopraphy provides simultaneous control of two key properties, the presentation of the terminal functional groups and a continuous increase in the surface density of functional groups on the surface. This control provides for drug screening assays using adherent cell-based experiments.
