Mechanical properties of graphene oxide: the impact of functional groups [PDF]

open access: yesApplied Surface Science, 525 (2020) 146554, 2020
In the current study, mechanical characteristics of graphene oxide (GO) as a promising substitute of graphene are systematically studied through molecular dynamics simulation. For this purpose, several GO samples having different concentrations of epoxide and hydroxyl functional groups are considered.

Epoxide Electroreduction

open access: yesJournal of the American Chemical Society, 2021
Selective hydrogenation of epoxides would be a direct and powerful approach for alcohol synthesis, but it has proven to be elusive. Here, electrochemically epoxide hydrogenation using electrons and protons as reductants is reported. A wide range of primary, secondary, and tertiary alcohols can be achieved through selective Markovnikov or anti ...

Epoxidation of Terpenes [PDF]

open access: yesCatalysts, 2021
Terpene epoxides are considered as potential primary intermediates in the synthesis of numerous green polymers including epoxy resins, polycarbonates, nonisocyanate polyurethanes and even some polyamides. In this chapter we describe recent efforts from our group to develop catalytic and noncatalytic processes for terpene epoxidation using a variety of ...

Structural and Electronic Properties of Oxidized Graphene [PDF]

open access: yesPhysical Review Letters 103, 086802 (2009)., 2009
We have systematically investigated the effect of oxidation on the structural and electronic properties of graphene based on first-principles calculations. Energetically favorable atomic configurations and building blocks are identified, which contain epoxide and hydroxyl groups in close proximity with each other.

Engineering graphene by oxidation: a first principles study [PDF]

open access: yesNanotechnology 21 (4), 045704-7 (2010), 2009
Graphene epoxide, with oxygen atoms lining up on pristine graphene sheets, is investigated theoretically in this Letter. Two distinct phases: metastable clamped and unzipped structures are unveiled in consistence with experiments. In the stable (unzipped) phase, epoxy group breaks underneath sp2 bond and modifies the mechanical and electronic ...

Ab-initio transport fingerprints for resonant scattering in graphene [PDF]

open access: yesPhys. Rev. B 86, 235417 (2012), 2012
We have recently shown that by using a scaling approach for randomly distributed topological defects in graphene, reliable estimates for transmission properties of macroscopic samples can be calculated based even on single-defect calculations [A. Uppstu et al., Phys. Rev. B 85, 041401 (2012)].
