Product selectivity in plasmonic photocatalysis for carbon dioxide hydrogenation...
Rhodium nanoparticles bombarded by UV can selectively produce mostly methane from CO2 and H2, rather than producing half methane and half CO.

Aberration-Free Ultrathin Flat Lenses and Axicons at Telecom Wavelengths Based on Plasmonic Metasurfaces - Nano Letters (ACS Publications)
New trick, using gold nanoantennas embedded in thin film silicon to turn a flat sheet into a near diffraction limited optical lens. Wide bandwidth too. Applicable for IR. Usable for large aperture beam expanders for a long range laser? But the demo seems to be a 1cm lens, and they are only seeing 1-10% efficiency.

A Super-Absorbent Solar Material - Technology Review
Interesting work since it isn't polarization dependent, unlike that loss medium research which seemed to need some phase canceling effects to work right.
