Hybrid photocathodes for solar fuel production: coupling molecular fuel-production catalysts with solid-state light harvesting and conversion technologies.

Artificial photosynthesis is described as the great scientific and moral challenge of our time. We imagine a future where a significant portion of our energy is supplied by such technologies. However, many scientific, engineering and policy challenges must be addressed for this realization. Scientific challenges include the development of effective strategies to couple light absorption, electro...

diff raction limit. However, the use of metamaterials in the design of hyperlenses meant losses through dissipation, and in some instances also a narrow operationfrequency range. In their study of acoustic lenses, Li and colleagues provide a slightly diff erent take on the original hyperlens idea by exploiting the diff erences between optical and acoustic waves. For acoustic waves, the wave equ...

Ultra-high current density water management in polymer electrolyte fuel cell with porous metallic flow field

Anode dry-out is the main mechanism identified to limit operation in an open metallic element (OME) PEFC. The fundamental water transport mechanisms in the OME PEFC were examined in order to engineer further improved performance and higher temperature operation required for efficient heat rejection. Specifically, the net water drag (NWD) was measured over a range of conditions and analyzed with...
