Porous graphene nanostructures are of great interest for applications in catalysis and energy storage. However, the fabrication of three-dimensional (3D) macroporous graphene nanostructures with controlled morphology, porosity and surface area still presents significant challenges. Here we introduce an ice-templated self-assembly approach for the integration of two-dimensional graphene nanoshee...

Carbon nanoscrolls (CNSs) belong to the same class of carbon-based nanomaterialsas carbon nanotubes. As a new category of quasi one dimensional material Graphene Nanoscroll (GNS) has captivated the researchers recently because of its exceptional electronic properties like having large carrier mobility. GNS shape has open edges and no caps unlike Single Wall Nanotubes (SWNTs) which are wou...

Abstract Recent studies have reported that adding nanoparticles to graphene enables macroscale superlubricity be achieved. This study focuses on the role of in achieving superlubricity. First, because nanoscrolls can formed with as seeds under shear force, applied load (or force) is adjusted manipulate formation and reveal relationship between graphene-nanoscroll superlubricating performance. S...

Carbon nanoscrolls (CNSs) with tubular structure similar to the open multiwall carbonnanotube have been of hot debate during recent years. Due to its unique property, Graphene Nanoscroll (GNS) have attracted many research groups’ attention and have been used by them. They specially studied on energy storage devices such as batteries and super capacitors. These devices can be schematically...

Graphene nanoscrolls with one-dimensional topological structure obtained by Archimedean-type spirals of graphene, inherit the intrinsic properties pristine graphene. They have some unique advantages, including open edges/ends, adjustable internal volume, and diameter. Notably, accommodation functionalized components in their interlayer is potentially a fantastic strategy to promote epoch-making...

Hydrogenation of graphene leads to local bond distortion of each hydrogenated carbon atom. Therefore, programmable hydrogenation of graphene can open up new pathways to controlling the morphology of graphene and therefore enable the exploration of graphene-based unconventional nanomaterials. Using molecular dynamics simulations, we show that single-sided hydrogenation can cause the scrolling of...

We report the direct formation of multiwalled carbon nanotubes (MWNT) by ultrasonication of graphite in dimethylformamide (DMF) upon addition of ferrocene aldehyde (Fc-CHO). The tubular structures appear exclusively at the edges of graphene layers and contain Fe clusters. Fc in conjunction with benzyl aldehyde, or other Fc derivatives, does not induce formation of NT. Higher amounts of Fc-CHO a...

Abstract We provide an updated study of some electronic properties graphene nanoscrolls, exploiting a related curved space Dirac equation for the charge carriers. To this end, we consider explicit parametrization in cylindrical coordinates, together with analytical solutions pseudoparticle modes living on two–dimensional background. These results are then used to obtain compact expression sampl...
