The Oak Ridge National Laboratory (ORNL) in Tennessee is known for 3D printing large objects, such as the aircraft part that became the Guinness World Record and the 3D printed vehicles exhibited during the IMTS in Chicago.
But now, ORNL's work seems to shift to the other end of mass manufacturing. The laboratory develops 3D printed nanostructures that are even smaller than bacteria.
ORNL researcher Philip D. Rack and Jason D. Fowlkes and Robert Winkler and Harald Plank of the Graz Electron Microscope Center in Austria, and Michael G. from the University of Tennessee Stanford's Brett B. Lewis worked together. Their complete paper has been published on ACS NANO.
3D printing is performed using focused electron beam induced deposition (FEBID), which is used in nanoscale manufacturing to provide precise control. In this case, electron beams are used to make complex three-dimensional shapes by reacting gas molecules on a controlled surface.
FEBID is a direct writing manufacturing method that involves computer-aided 3D simulation and 3D design (CAD). Through simulation, the researchers were able to predict the degree required to move the electron beam to create the desired geometry.

A floating shelf is a form of shelf with its wall fixings hidden within the shelf board, with no visible supporting brackets. It can be supported on hidden rods or bars that have been attached to studs. A thick floating shelf may be made of a hollow-core shelf glued to a cleat.
A floating shelf may have two or more channels open from the back towards, but without reaching, the front, into which slide fasteners attached to the wall, typically held in place by screws inserted through the bottom of the shelf.
For typical floating shelf supports, a supplier suggests that floating brackets with a diameter of 12mm can support a shelf at least 22mm thick loaded with 20kg, and 18mm brackets can support 30kg on a 28mm shelf.
This description is in reference to one particular type of floating shelf support, others options are available. Also not to be confused with corner shelves, which would require entirely different supports to make them "float".
Floating shelves are a good fit for a contemporary minimalist style interior.They can be used to expand storage space, atop a radiator to double as storage, or inside a hallway to double as a console table.
