Ultrafast carrier phonon dynamics in NaOH-reacted graphite oxide film

Dongwook Lee, Xingquan Zou, Xi Zhu +6

NaOH-reacted graphite oxide film was prepared by decomposing epoxy groups in graphite oxide into hydroxyl and -ONa groups with NaOH solution. Ultrafast carrier dynamics of the samp…

Effects of the reaction cavity on metastable optical excitation in ruthenium-sulfur dioxide complexes

Anthony E. Phillips, Jacqueline M. Cole, Thierry d'Almeida +1

We report photoexcited-state crystal structures for two new members of the [Ru(SO_2)(NH_3)_4X]Y family: 1:X=H2O, Y=(+/-)-camphorsulfonate_2; 2:X=isonicotinamide, Y=tosylate_2. The…

Distinction of disorder, classical and quantum vibrational contributions to atomic mean-square amplitudes in dielectric pentachloronitrobenzene

Jacqueline M. Cole, Hans-Beat Burgi, Garry J. McIntyre

The solid-state molecular disorder of pentachloronitrobenzene (PCNB) and its role in causing anomalous dielectric properties are investigated. Normal coordinate analysis (NCA) of a…

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…

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…
