The cyclic octapeptide cycfo-[-(D-Ala-L-Glu-D-Ala-L-Gln)2-] has been designed by Ghadiri and co-workers to generate a hydrogen-bonded organic nanotube having an internal diameter of approximately 0.7-0.8 nm (Fig. 20.1.5). 

The baseline design for the current S -I work is the system configuration described in a report titled High Efficiency Generation of Hydrogen Fuels Using Nuclear... 

As stated earlier, an increased interest is currently being concentrated on smaller-scale hydrogen production for fuel cell applications ranging from industrial to residential and mobile implementations. An especially important emphasis has been placed on the design of on-board fuel processors capable of generating the hydrogen necessary to power vehicles. Another application of the mobile fuel processor under development is the portable processor/fuel cell system capable of powering electronic devices with liquid hydrocarbon fuels, as replacement for batteries.24 26... 

Sandia s design thermally actuates an exothermic reaction of metal hydride with water to generate the hydrogen on board the microsystem. The pressure created by this reaction and the low viscosity of the hydrogen enable the high flow rate of the mobile phase, which, in turn, enables the desired 2 -second chromatographic separation. 

Figure 13. Schematic of the photoelectrolytic cell designed for the generation of hydrogen using a light source (UV or visible). The anode is carbon-doped titania nanotubular arrays prepared by the sonoelectrochemical anodization technique and the cathode is platinum nanoparticles S3mthesized on undoped titania nanotubular arrays.
