Researchers at Lawrence Livermore have achieved greater energy storage density by 3-D printing structures with graphene-based aerogels to
In research published in Nature Communications , the LLNL research team were able to produce a predetermined architecture for a graphene-based aerogel, which previously had always been random, by using 3-D printing. By being able to define the architecture, the researchers were able to improve the material’s performance.
The 3-D printing process used for fabricating these aeorgels [sic] is called direct ink writing. In the process, graphene oxide (GO) inks are combined with an aqueous GO suspension and a silica filler to create the ink. This ink is then extruded through a micronozzle to layer up the structure. The final structure is then put into hydrofluoric acid where the silica is burned off.
Awesome work with an amazing material, but I'd hate to be the guy that has to handle the hydrofluoric acid.

Will hover around you all day and all night, their sensors recording your vital signs and enforcing compliance with your doctor's orders. Don't like ObamaCare Drones? Obama won, citizen. You voted for Obama, didn't you? Don't even think about smashing ObamaCare drones; replacement costs will be added directly into your tax penalty. Are you glad improved battery life makes ObamaCare Drones possible?
