Graphite is a material condensed from aromatic hydrocarbon that forms an infinite plane that exhibits an amphoteric feature. Structurally, a number of benzene rings form a solid planar sheet. A number of layers are formed from numerous unit cells, a so-called grapheme. A graphene sheet has an electron structure, which expands π-electrons into a two dimensional space. Graphite has AB-stacked bilayers of graphene. Because the interaction between two sheets is weak, their electronic structure may...

The effects of ammonia-treated graphene oxide (GO) on composites based on epoxy resin were investigated. Ammonia solutions of different concentrations (14?28%) were used to modify GO. Nitrogen functional groups were introduced on the GO surfaces without significant structural changes. The ammonia-treated GO-based epoxy composites exhibited interesting changes in their mechanical properties related to the presence of nitrogen functional groups, particularly amine (C-NH2) groups on the GO...

Cellulose fibers were stabilized by treatment with an electron-beam (E-beam). The properties of the stabilized fibers were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. The E-beam-stabilized cellulose fibers were carbonized in N₂ gas at 800°C for 1 h, and their carbonization yields were measured. The structure of the cellulose fibers was determined to have changed to hemicellulose and...

In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist...

Carbon fibers are prepared by stabilizing pitch fibers accompanying electron beam (E-beam) irradiation. The carbon fibers pretreated by E-beam irradiation achieve a higher stabilization index than the carbon fibers that are only heat-stabilized. In addition, the carbon fibers subjected to E-beam irradiation in the stabilization step exhibit a comparable tensile strength to that of general purpose carbon fibers. The carbon fibers pretreated with an absorbed dose of 3000 kGy have a tensile...

Pyrolized fuel oil (PFO) was reformed by novel electron beam (E-beam) radiation, and the elemental composition, chemical bonds, average molecular weight, solubility, softening point, yields, and density of the modified patches were characterized. These properties of modified pitch were dependent on the reforming method (heat or E-beam radiation treatment) and absorbed dose. Aromaticity (Fa), average molecular weight, solubility, softening point, and density increased in proportion to the...

Double walled carbon nanotubes (DWCNTs) are considered an ideal model for studying the coupling interactions between different concentric shells in multi-walled CNTs. Due to their intrinsic coaxial structures they are mechanically, thermally, and structurally more stable than single walled CNTs. Geometrically, owing to the buffer-like function of the outer tubes in DWCNTs, the inner tubes exhibit exciting transport and optical properties that lend them promise in the fabrication of field-effect...

I became an instructor at Chungnam National University in 1976, and was at Cleveland State University as a visiting professor in 1980/1981. My major was Biochemical Engineering and I was studying the hydrolysis of biomass to obtain alternative energy sources (Gasohol). I presented my research results (Attrition Bioreactor) at an ACS meeting, and this work became one of the ‘applications and unit operations’ selected for presentation in “Biotechnology in Industry”, published by Ann Arbor...

I started carbon research in April, 1958 as a graduate student in the laboratory of Prof. T. Noda at Nagoya University. My focus was on the graphitization of various carbon materials using X-ray diffraction. I worked on carbon materials at Nagoya University, Toyohashi University of Technology, Hokkaido University, Aichi Institute of Technology and then in my own home; I did this for more than 50 years. During this period, I fortunately met many excellent advisors, collaborators and students, and...

My introduction to carbon science was unplanned and unexpected. After I received my B.A. in physics from the University of Cambridge (UK) in 1960, I agreed to take an appointment at the United Kingdom Atomic Energy Authority (UKAEA) Atomic Energy Research Establishment (AERE), Harwell, UK. Starting September 1, I was to work on a project studying focused collision sequences in metals. For personal reasons, I was not able to report until a month later, when I was informed that my original...
