Monolithic graded-refractive-index glass-based antireflective coatings: broadband/omnidirectional light harvesting and self-cleaning characteristics - Journal of Materials Chemistry C (RSC Publishing)
So, new surface coating technique that uses nanostructures to achieve a superhydrophobic effect, rather than polymer or powder surface coating, that is also much more abrasion resistant. Also conveniently antireflective.

Enhanced photovoltaics inspired by the fovea centralis : Scientific Reports : Nature Publishing Group
Interesting nanostructure research to improve solar cell efficiency by improving light capture. The takeaway is that straight right cylinder nanowires actually perform worse than nanowires with uneven shapes, one extreme being a nanofunnel (wouldn't this be more like a cone or frustrum though?)

Research of Graphene-reinforced Aluminum Matrix Nanocomposites
Seems like if the powder grind/mix is well done, you get pretty awesome graphene nanoflake reinforced aluminum composites. Apparently they got over a previous issue, where CNT's in an aluminum matrix turned into aluminum carbide, lowering materials properties.

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.

I think they are basically trying to sell a thin film prismatic lens array with spectrum waveguiding as an aftermarket upgrade to existing solar PV systems. Wait, now they are doing photoelectrochemical hydrogen production with the intent of synthetic natural gas production? Seems they are close to the magical 1.23V open circuit voltage needed for direct solar hydrogen production.

Adding Graphene Makes Polymers 31-53% Stronger Versus Carbon Nanotubes 3-20% Enhancement
This makes sense in a way, having sheets of nanoscale stuff, particularly aligned with the expected stresses. It's similar to the difference between a chopped fiber fiberglass structure, and a deliberately laid woven fiberglass mat structure. I imagine using full sheets of graphene aligned with stresses, rather than just broken up platelets, will see a huge performance boost. But, like chopped fiberglass, this is simpler to mass produce (at least until roll to roll graphene manufacturing comes of age)
