Computed Metallofullerene Yields in the X@C74 and Z@C82 Series

Slanina Z., Akasaka T., Nagase S., Institute for Molecular Science, JP

A series of metallofullerene formations X@Cn with one common cage Cn and variable encapsulated metals X is treated. The equilibrium composition of the reaction mixture is controlled by the encapsulation equilibrium constants and the saturated [...]

Fabrication of Micro Photonic Crystals for Handling of Terahertz Electromagnetic Waves

Kirihara S., Sano D., Niki T., Ohta N., Takinami Y., Osaka University, JP

Electromagnetic waves in terahertz ranges are possible to harmonize with molecule vibrations of various saccharides or proteins, and expected to control the biological material syntheses through the frequency excitements. In this investigation, metals and ceramics [...]

Mechanical Properties of Metallized Single Nanofibers

Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Kimura N., Bang H-S., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Watanabe Y., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Enomoto Y., Kim B.S., Kim H-R., Kim H-Y, Kim I.S., Kimura N., Shinshu University, JP

Our final goal is to make the metal nanofibers having good properties of metal and explore the mechanical properties of metalized single nanofibers. We are expecting that they would be strong like general metals. In [...]

Enhancement of Defect Tolerance in the QCA-based Programmable Logic Array (PLA)

Notsu T., Miura K., Nakamae K., Osaka University, JP

In this study we analyze the precedent AND/OR plane cell of a programmable logic array (PLA) based on the quantum-dot cellular automata (QCA), then propose a modified layout that has better defect tolerance. We analyzed [...]
