Abstract: A process and device for electrostatically controlling an ionic environment in a droplet, such as in a droplet-based platform including polymerase-chain reaction (PCR) applications. The process includes providing a chip that comprises at least a pair of electrodes, placing a salt-containing droplet on the chip, and then applying a bias across the electrodes to accumulate ions near surfaces of the electrodes, thereby depleting a bulk salt concentration in regions of the droplet away from the electrodes.

Abstract: Conductive layer(s) in a thin film photovoltaic (TFPV) panel are divided by first scribe curves into photovoltaic cells connected in series. At least one of the layers is scribed to isolate a shunt defect in a cell from parts of that cell away from the defect. The isolation scribes can substantially follow or parallel current-flow lines established by the design of the panel. A TFPV panel can be altered by, using a controller, automatically locating a shunt defect and scribing at least one of the conductive layers along two spaced-apart second scribe curves. Each second scribe curve can intersect the two first scribe curves that bound the cell with the defect. The two second scribe curves can be on opposite sides of the defect.
