The promise of deep grooves | Argonne National Laboratory
So this is atomic layer deposition INTO a polymer rather than surface coating it, effectively using the polymer as a pattern to build up inorganic structures.

Video: Diamond-like coatings save fuel
20 micrometer thick tetrahedral amorphous carbon coatings (ta-c) laid down with a pulse laser arc yield diamond surface coatings. Suitable for bearings, but doesn't diamond burn?

Welcome to Weber Manufacturing (MFG)
Interesting nickel vapor deposition manufacturing tech, for making liners and such. There was a suggestion of using depleted nickel as a liner for molten salt reactors in the core, so their manufacturing tech might fit well with the concept.

NSTRMNT — SUSPENDED DEPOSITIONS
Interesting 3D printer work, using a robot arm mounted pump/needle to inject UV curable resin into a suspension gel. After squirting in resin (which can even be sucked back out in case of mistakes), the suspension gel tank is UV exposed to harden the resin for later removal. The suspension makes certain structures easier to do as the object to be printed in continuously supported.

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.

Biorock
If you accept that direct room temperature electrolysis has a poor efficiency, and that doing hydrogen production using mineral accreation electrodes in seawater has a similar efficiency, one can make the arguement that you might as well make the Biorock if you are going to do direct electrolysis anyways. You also create the semiporous seacrete/artifical rock that can be used as stable foundations for coral growth and ocean ecosystem recovery, or as a direct building material like concrete (though not high strength).

Planar Energy - Powering Possibilities
University of Central Florida says the ionic conductivity is comparable to liquid electrolytes, so there is potential to create solid state batteries with triple the performance of current lithium ion batteries at half the cost.
