Optimization of a wall-less Hall thruster
So they turned the magnet poles and shapes the anode to match the magnetic field lines, so the anode doesn't get eroded away like a typical hall effect thruster

3D printing tungsten » The Unwanted Blog
Interesting comment about using 3D printing to create specialty engineered alloys, specifically silver impregnated tungsten for better heat conductivity internally to avoid localized melting on tungsten rocket nozzle throats. In this application, it wouldn't be a conventional casted alloy, nor would it be a gradient mixed/poured alloy either, but perhaps a design specific 3D spacial gradient? Or would you be doing the design equivalent of embedding a heat pipe of sorts in the tungsten for short range directed heat transfer?

ACT-RPR-NPS-1107-NTER-paper-final - ACT-RPR-PRO-1107-LS-NTER.pdf
NTER, a nuclear thermal electric rocket design. Uses LH2 propellant to cool a helium brayton cycle turbine fed by a NTR that heats hydrogen and helium, then tries to supercharge the supersonic nozzle exhaust with an induction loop (which seems to require cesium seeding in the exhaust??). Also has optional oxygen feed, to emulate LANTRN. Seems like you could do better with the NTR feeding a VASIMR though...

Umbrella methodology for a deployable high surface area heatshield. Early research way back at the start of the space age had concepts using steel meshes for the umbrella skin, with some configurations not umbrella shaped, bat rather more like a shuttlecock or fluted glass.
