Free-Standing Epitaxial Graphene [PDF]

Nano Letters, 2009
We report on a method to produce free-standing graphene sheets from epitaxial graphene on silicon carbide (SiC) substrate. Doubly clamped nanomechanical resonators with lengths up to 20 microm were patterned using this technique and their resonant motion was actuated and detected optically.

Practical research of free standing rack (Seismic experiment study on full scale free standing rack)

Nihon Kikai Gakkai ronbunshu, 2015
The spent fuel taken out of a plant reactor is temporarily stored in a spent fuel rack. This fuel will often have to be stored in the rack for long periods before it can be moved to a reprocessing facility. Therefore, the spent fuel rack must have a high
