For the demonstration device in Fig. 4.2, polyaniline was chosen as the anode material because it is flexible, conducts current, and is transparent to visible light (there is no indium-tin-oxide (ITO) layer in the device of Fig. 4.2). More generally,... 

Experimental work can be divided into work that examines stmcture of fluids inside of the carbon nanotubes using techniques such as neutron diffraction, NMR, and in situ TEM and the studies that examine transport properties using specially fabricated devices in which carbon nanotubes serve as pores (Fig. 1). Two experimental groups have so far demonstrated devices that allow studies of transport through graphitic carbon nanotubes. As synthesized carbon nanotube mats have considerable spacing between individual carbon nanotubes. Researchers have, therefore, developed methods to fill those spaces with a dense material and confine transport... 

Wollaston was not present at the Royal Society the night Volta s paper was read, for on the previous day he haui set off on a four week tour of the Lake District with Hasted. Before his departure he had reduced the scale of his electrolytic cell even further, for he took a small demonstration device with him. As Hasted was to recall He had a minute tube in his pocket which with a wire connecting thro a few drops of muriatic acid the zinc and silver, shewed the whole principle, and first set Dr, Currie, whom he saw on his way back thro ... 

We also know that Wollaston had, in partnership with Smithson Tennant, invested heavily in the purchase of crude platina ore in late 1800, and from 1801 to 1805 he perfected the techniques of powder metallurgy that led to the production of malleable platinum in 1805 (28). Only when the processing of platinum became regularized about 1810 did Wollaston turn his attention again to electrochemistry, once more in connection with a small, demonstration device. 

The requirements we have adopted for the SIRTF arrays are listed in Table 1 and compared with the measured performance of the demonstration device.
