Astronomical chemical evolution from graphene to polycyclic aromatic hydrocarbon reproducing observed infrared spectrum
Norio Ota
Interstellar ubiquitous infrared spectrum (IR) due to polycyclic aromatic hydrocarbon (PAH) was observed in many astronomical dust clouds. A capable astronomical chemical evolution…
Design of Magnetic Graphene-ribbon for 100 Tera-bit/inch2 Information Storage Media
Norio Ota
Magnetic graphene-ribbon is a candidate for realizing future ultra high density 100 tera bit/inch2 class data storage media. Multiple spin state analysis was done based on the dens…
