The structure of graphite oxide: Investigation of its surface chemical groups
D. W. Lee, L. De Los Santos V., J. W. Seo +4
The structure of graphite oxide (GO) has been systematically studied using various tools such as SEM, TEM, XRD, Fourier transform infrared spectroscopy (FT-IR), X-ray photoemission…
Preparation of carbon nanotubes from graphite powder at room temperature
D. W. Lee, J. W. Seo
We develop a new chemical route to prepare carbon nanotubes at room temperature. Graphite powder is immersed in a mixed solution of nitric and sulfuric acid with potassium chlorate…
/ carbon ratio in graphite oxide with different preparation times
D. W. Lee, J. W. Seo
Graphite oxide is an amorphous insulator. Although several models have been suggested, its structure remains controversial. To elucidate this issue, 5 samples were prepared by the…
Tunable magnetic interaction at the atomic scale in oxide heterostructures
J. W. Seo, W. Prellier, P. Padhan +9
We report on a systematic study of a number of structurally identical but chemically distinct transition metal oxides in order to determine how the material-specific properties suc…
Transparent and flexible polymerized graphite oxide thin film with frequency-dependent dielectric constant
D. W. Lee, J. W. Seo, G. R. Jelbert +4
Here we report on the preparation of transparent and flexible polymerized graphite oxide, which is composed of carbons with sp3-hybridized orbitals and a non-planar ring structure,…
