Plasmonic p–n Junction for Infrared Light to Chemical Energy Conversion - Journal of the American Chemical Society (ACS Publications)
Making hydrogen gas with IR light. Though one wonders where direct conversion with this photocatalyst is better than using a frequency converter intermediary and a different photocatlyst...

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.

Hybrid Molecule–Nanocrystal Photon Upconversion Across the Visible and Near-Infrared - Nano Letters (ACS Publications)
Interesting hybrid organic/inorganic frequency converter, takes 2 IR photons in, upconverts to single higher frequency photon. Not quite a frequency doubler, but possibly still useful. Since you aren't wasting IR inputs

Purdue News - Natural nanocrystals shown to strengthen concrete
Notably not directly increasing strength, but rather aiding in wetting the cement during the hydration steps, which produces stronger concrete.

Copper hexacyanoferrate battery electrodes with long cycle life and high power : Nature Communications : Nature Publishing Group
High cycle durability cathode material, if matched with a hydrated potassium ion aqueous electrolyte. Still searching for a suitable anode though. May be suitable for grid energy storage due to ease of manufacturing and cost.

Scavenging energy waste to turn water into hydrogen fuel, Headlines for March 12, 2010, UW-Madison Engineering
Interesting that they used ultrasonic frequencies to drive the nanofibers. I wonder if that is due to the fiber length being the limiting factor on available driving frequencies?
