Window film could even out the indoor temperature using solar energy | Chalmers
Neat trick is it's yellow when the sun isn't shining, but clears up when it is shining, then goes yellow again while reradiating stored heat

Broadband Light Management with Thermochromic Hydrogel Microparticles for Smart Windows: Joule
Using 500nm thermochromic nanoparticles to turn glass frosty at 85F, and reject outside IR heat. So if it gets warm, a window can turn transluscent to stop solar heating.

Self-Deployed Space or Planetary Habitats and Extremely Large Structures
NIAC phase 1 results. NRO research related as well for deployable space telescopes. Rigidized UV cured polymer thin film bubbles for space applications. Possible flat primary mirrors/solar sails, but if they are making spheres, making curved mirror segments should be doable. If you use 6 stabilizing hoops as cut lines, can get 6 sphere segments without much waste (waste could be repurposed as additional mirror segments)

[1708.09539] Coherent Atomically-Thin Superlattices with Engineered Strain
Stiching 3 molecule thick crystal lattices together. Notably, they made an LED, and could mess with the color output by stretching the thin film, which suggests a new variable color LED method.

Highly efficient and ultra-broadband graphene oxide ultrathin lenses with three-dimensional subwavelength focusing : Nature Communications : Nature Publishing Group
Sorta breaking the diffraction limit for ultrathin flat lens in a more manufacturable format, with fresnel rings being laser etched. I wonder if this would be applicable to DARPA MOIRE project, assuming you could make a large monolithic thin film of graphene.

So these guys are actually producing NFC thin film electronics in a fast roll-to-roll process, finally dropping the per sticker cost. Though native thin film NFC sticker area is still a bit large, due to the limits of the materials in the printable electronics. Xerox will produce?

BNL Newsroom | Breakthrough Iron-based Superconductors Set New Performance Records
New high current/high magnetic field/high temperature superconductor that is iron based that beats the pants off of existing iron and cuperate superconductors. Demonstrated 1MA/cm2 critical current, 200KA/cm2 at 30T at 43K (not quite LN2 temps but close), and they think they can up the temperature by further tweaking the layering.
