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…
Relaxor characteristics at the interfaces of [NdMnO3/SrMnO3/LaMnO3] superlattices
J. W. Seo, B. T. Phan, J. Stahn +2
We have investigated the magnetic properties of transition metal oxide superlattices with broken inversion symmetry composed of three different antiferromagnetic insulators, [NdMnO…
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,…
Magnetism in graphite oxide: The role of epoxy groups
D. W. Lee, J. M. Cole, J. W. Seo +4
We investigate the magnetism in graphite by controlled oxidation. Our approach renders graphite an insulator while maintaining its structure. Fourier transform infrared spectroscop…
