Fossil-free Steel - Hybrit
All hydrogen reducing steel manufacturing, rather than using carbon/coke. Energy intensive (when taking hydrogen production by electrolysis into account) but "green" (I suppose that includes induction based furnaces). Not actually new per se, just not at industrial levels

Back-bonding between an electron-poor, high-oxidation-state metal and poor π -acceptor ligand in a uranium( v )–dinitrogen complex | Nature Chemistry
Uranium dinitrogen shouldn't be happening according to the models, but it does. Haber (of Haber-Bosch process fame) noted uranium being a suitable cataylst for the process, which means they knew back then that uranium was probably doing this (but not why)

PNNL: News - ShAPEing the future of magnesium car parts
Basically pushing friction stir welding products through an extrusion die, rather than heating the whole mandrel or heating the whole die. Which implies improved microstructure for the extrusion, and that anything that can be friction stir welded can also be extruded (perhaps continuously?)

Foodtech | Induction Food Systems | United States
Similar to microwave based on-demand water heaters, this uses a heating element suspended in a pipe, heated by an external induction coil. Useful for flash pasteurization and heat processing of liquids and liquefied foods. Apparently less energy consuming compared to steam pasteurization.

Graphene Spun into Meter-Long Fibers - Scientific American
So graphene oxide liquid crystals were dried out to make meters long (but imperfect) fibers which are weaker than normal carbon fiber, but have great conductivity. Has this been commercialized into low weight electrical wire yet?

Joining gun bonds metal and plastic within seconds
Adheasiveless, rivetless joining of plastic and metal, by laser etching tiny holes at the joint position in the metal, fast melting the plastic into the holes, then cooling the plastic so that it grabs the holes.

APS -71st Annual Meeting of the APS Division of Fluid Dynamics - Event - How do wombats make cubed poo?
So, research how wombats make cubic poop may provide a line towards a third method of manufacturing soft cubic solids. Why is it cubic is speculated as due to ease of building piles, since wombats have poor eyesight.

Recombinant Spidroins Fully Replicate Primary Mechanical Properties of Natural Spider Silk - Biomacromolecules (ACS Publications)
So they got bacteria to build silk proteins with are almost twice as long as real spider silk proteins, thus the doubled protein is now a near match in performance to true spider silk fiber (true spider silk fiber benefits from good protein design and spinner design though). They seem to think it should be possible to use the fusing method to build even longer proteins to up the strength.

Titomic - Industrial Scale Additive Manufacturing, 3D Printing, Titanium, Innovative, Melbourne, Australia
Using supersonic metal particle sprays to get get powder fusion via kinetic impact, not too far from older metal cold spraying techniques. Not using bulk heating so less likely to have warped parts from SLS/SLM methods. Doing aerospace grade titanium, with an ITAR compliance area as well?
