Luminomagnetic bifunctionality of Mn(2+)-bonded graphene oxide/reduced graphene oxide two dimensional nanosheets.
Herein, we report the luminomagnetic bifunctional properties of two-dimensional (2D) Mn(2+) bonded graphene oxide (GO)/reduced graphene oxide (RGO) nanosheets synthesized using a facile route of oxidation followed by a solvothermal reduction method. Photoluminescence (PL) studies (excited by different wavelengths) revealed that the resonant energy transfer between Mn(2+) and sp(3)/sp(2) cluster...
متن کاملTwo-dimensional shape memory graphene oxide
Driven by the increasing demand for micro-/nano-technologies, stimuli-responsive shape memory materials at nanoscale have recently attracted great research interests. However, by reducing the size of conventional shape memory materials down to approximately nanometre range, the shape memory effect diminishes. Here, using density functional theory calculations, we report the discovery of a shape...
متن کاملAnomalous piezoelectricity in two-dimensional graphene nitride nanosheets.
Piezoelectricity is a unique property of materials that permits the conversion of mechanical stimuli into electrical and vice versa. On the basis of crystal symmetry considerations, pristine carbon nitride (C3N4) in its various forms is non-piezoelectric. Here we find clear evidence via piezoresponse force microscopy and quantum mechanical calculations that both atomically thin and layered grap...
متن کاملToxic Gas Remediation by Graphene Oxide Nanosheets
Deemed the worlds largest environmental health issue, air pollution has been shown to be a more potent danger than previously thought. Increasing concern regarding major gas pollutants nitrogen dioxide (NO2), ammonia (NH3), and ozone (O3) has sparked research in the field of gas adsorption as a method to remove these gases from the atmosphere. Using first principles calculations based on the De...
متن کاملSuitable chemical methods for preparation of graphene oxide, graphene and surface functionalized graphene nanosheets.
This article presents the suitable chemical method for preparation of graphene oxide nanosheets. In order to examine the effects of HNO3/H2SO4 ratio on interlayer spacing and its comparison, the oxidation of graphite with HNO3 and H2SO4 in 1:2 and 1:3 volume ratios was done. Based on the reaction time and interlayer spacing, it was found that the optimum results were obtained when reaction was ...
