Figures

Image of FIG. 1.
FIG. 1.

Schematic diagram of npn transistor (Q) sink current source circuit for driving LEDs. The base voltage is limited by a zener diode (D) and the diode current is limited by the emitter resistor (R).

Image of FIG. 2.
FIG. 2.

Schematic diagram of pulsed 8 × 8 LED array circuit. Details of the circuit are given in the text.

Image of FIG. 3.
FIG. 3.

Schematic diagram of two-electrode potentiostat circuit. Details of the circuit are given in the text.

Image of FIG. 4.
FIG. 4.

Photoelecthrochemical materials discovery system: (a) FTO plate spotted with iron oxide test samples; (b) test plate in dish containing electrolyte, positioned above the LED array; (c) LED array (black box) and two-electrode potentiostat (aluminum box).

Image of FIG. 5.
FIG. 5.

Signal-averaged data from ten scans of the iron oxide test plate shown in Figure 4. The applied potential was 0.1 V. The smaller blue bars between the tall bars represent interchannel crosstalk (see text).
