Cyborg Bacteria Change the Game in Carbon Dioxide Reduction - IEEE Spectrum
tweaked bacteria equipped with cadmium sulfide nanocrystals have superior photosynthesis efficiency, converting sunlight and CO2 into acetic acid, which can be fed to other tweaked E. Coli who can convert acetic acid to butanol.

A regenerable oxide-based H2S adsorbent with nanofibrous morphology : Nature Nanotechnology : Nature Publishing Group
Possible new absorbent that might allow sulfur removal from natural gas or coal/biomass derived syngas without a cooling/liquid step (which normally complicates the process and introduces energy inefficiencies). This would make coal or biomass based syngas much more appealing, especially for advanced syngas combustion cycles that allow for easier carbon capture.

Technology Review: TR10: Liquid Battery
Interesting idea, but what about the fundamental principal of batteries, being that you get better energy density by increasing the surface area of the electrodes? Wouldn't the liquid electrode layer represent the least amount of surface area possible?
