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.

Phys. Rev. Lett. 111, 134803 (2013): Laser-Based Acceleration of Nonrelativistic Electrons at a Dielectric Structure
Interesting zero to fast electron accelerator research, which would dovetail nicely with that recent work for accelerating near relativistic electrons. Surface waves, so surface plasmons?

Microtags for anti-counterfeiting & brand protection from Trutag
Some sort of weird passive spectral tag, using spectral response spikes as a kind of passive barcode. Tiny and made of inert silica so edible.

Carbon Dioxide Capture from the Air Using a Polyamine Based Regenerable Solid Adsorbent - Journal of the American Chemical Society (ACS Publications)
Interesting low temperature PEI absorber design, depositing it on fumed silica to increase surface area for CO2 capture from atmospheric air. Low temps (85C) drive the Co2 back out, making absorber regeneration relatively simple.
