We employ plane-wave pseudopotential density functional calculations to show that the lowest energy D6h C36 crystal is a highly bonded network of hexagonal planes of C36 units with AB stacking. This crystal is significantly more dense and lower in energy than previously proposed structures. We demonstrate that Na is the largest alkali atom that can be intercalated into the crystal structure wit...

Torus networks of moderate degree have been widely used in the supercomputer industry. Tori are superb when used for executing applications that require near-neighbor communications. Nevertheless, they are not so good when dealing with global communications. Hence, typical 3D implementations have evolved to 5D networks, among other reasons, to reduce network distances. Most of these big systems...

There are several methods introduced to refining the accuracy of Photonic structures. No one has as yet studied the effect of Neural Networks in refining the accuracy of the photonic structure of the Photonic Crystal Fibers. In this paper we use The simulation that will be conducted using artificial neural networks to refining the accuracy of the photonic crystal fibers &.Artificial neural netw...

The fabrication of a foldable, compact liquid crystal actuator based on oxetane reactive monomers is reported. free-standing network films are optically clear, flexible, and have easily tunable anisotropic thermal mechanical properties. networks demonstrate excellent one-way shape memory properties, with good temporary fixation complete recovery. In addition, the flexible polyether backbone res...
