(PDF) Concept of an Accelerator-Driven Advanced Nuclear Energy System
This is that chinese ASDR concept using solid micrograins as a pumpable solid coolant that doubles as the neutron spallation target for the particle accelerator. Apparently there were concerns over the thermal shock from a beam trip event requiring a more robust neutron target.

Using a silicon chip coated in nanoantennas, they effectively made a metamaterial mirror for a laser, allowing a 1D laser scanner LIDAR that is solid state. Made using methods similar to LCD manufacturing, which means the beam can be actively scanned at will, so not a fixed scanning cycle either.

Fully Integrated Hybrid Silicon Two Dimensional Beam Scanner | Bowers
The underlying tech behind Strobe Inc.'s (now GM/Cruise) fancy pants chip LIDAR. Uses optical phased array for one dimensional scanning, and frequency variation through a prism lens to achieve scanning in the other dimension, rather than a full 2D optical phased array (so easier to make?)

In-drop capillary spooling of spider capture thread inspires hybrid fibers with mixed solid–liquid mechanical properties
So spider silk has a watery glue that also functions as a local spool to pull in loose silk thread. Now that has been emulated with oil droplets and plastic filament.

Apparently they have a good high temperature steam electrolysis SOEC that can produce hydrogen at decent efficiencies, for feeding into a RWGS conversion reactor syngas production rig, to eventually produce synthetic methane (combining syngas from the reactor with additional H2 from the SOEC), or eventually via FT, synthetic liquid fuels. They don't seem to be doing a coelectrolysis SOEC to crack steam and CO2 simultaneously in the same cell stack though.

A new hybrid technology - staged combustion
Interesting comment on a novel dual injector hybrid rocket. I wonder for a practical rocket, the lower injector could use something similar to a reverse vortex combustion chamber, where the HTP is swirled up from the throat, providing some cooling to the throat area?

Motorbike Generates Electricity Using Its Exhaust Gas -- Tech-On!
Bizarre hybrid device, that uses unburnt hydrocarbons in scooter exhaust gas to heat/run a SOFC fuelcell, which also has thermoelectric elements wrapped around the SOFC tubes to capture waste heat as well. Though my first question would be why use a crappy two/four stroke scooter engine in the first place? Why not a series hybrid powerplant, with a microturbine generator with fuelcell combustor? Though I suppose as an aftermarket mod, as long as it doesn't raise exhaust gas pressure losses too much, it might be an easy conversion...
