High Elastic Moduli of a 54Al2O3-46Ta2O5 Glass Fabricated via Containerless Processing : Scientific Reports
New high strength glass, but it requires a high temperature air levitation furnace setup (which is expensive to operate), and uses tantalum, which is stupid expensive. The glass by weight of the component ingredients alone would cost more than silver by weight.

Research of Graphene-reinforced Aluminum Matrix Nanocomposites
Seems like if the powder grind/mix is well done, you get pretty awesome graphene nanoflake reinforced aluminum composites. Apparently they got over a previous issue, where CNT's in an aluminum matrix turned into aluminum carbide, lowering materials properties.

7. Experimental Proof of Concept for an Electrochemical Plasma Thruster nstp-pathfinder-project-list.pdf (application/pdf Object)
Interesting self sustaining plasma thruster that in principle generates the power needed for plasma acceleration without a powerful external power source. I guess you use a wirefeed to feed in the aluminum wire/rod at the thruster core? Consumes oxygen gas, aluminum wire, and helium buffer gas (how much?)

Sumitomo Electric Industries, Ltd. | Press Release (2011) Development of Porous Aluminum “Aluminum-Celmet”

Engineers creating carbon-negative Mars rocket
Basically a hybrid solid rocket, using aluminum powder grain fuel and CO2 (gas? solid?) for fuels, with the CO2 being collected locally on the martian surface. Though considering all the ISRU work done so far, I would have thought producing oxygen for the oxidizer would have been more attractive from an overall integrated system/mass/power budget perspective...

News Release : SHOWA DENKO K.K.
Someone pointed out that ideal plant growth acceleration under artificial lighting would be 92% red LED's and 8% blue LED's, and that white LED's are a waste of energy. So these special red LED's by SDK would be great for indoor agriculture and specialty photobioreactors for algae production.

Though there will be the inevitable comments about underground growops in a certain variant hemp industry...
