Seed/catalyst-free vertical growth of high-density electrodeposited zinc oxide nanostructures on a single-layer graphene

We report the seed/catalyst-free vertical growth of high-density electrodeposited ZnO nanostructures on a single-layer graphene. The absence of hexamethylenetetramine (HMTA) and heat has resulted in the formation of nanoflake-like ZnO structure. The results show that HMTA and heat are needed to promote the formation of hexagonal ZnO nanostructures. The applied current density plays important ro...

Vibration Analysis of Circular Single-Layer Graphene Sheet Using Finite Element Method

Graphene sheets are combined of Honeycombs lattice carbon-carbon bonds which have high natural frequencies, high strength, and high conductivity. Due to important applications of the graphene sheets particularly at higher frequencies, the study of their dynamic behavior is important in this frequency range. From Molecular Dynamics (MD) point of view as the dimensions of graphene sheet incline, ...

Step-templated CVD growth of aligned graphene nanoribbons supported by a single-layer graphene film.

We present chemical vapor deposition (CVD) growth of a hybrid structure of aligned graphene nanoribbons (GNRs) supported by a single-layer graphene sheet. The step structure created on the epitaxial Co film is used to segregate arrays of aligned GNRs. Reflecting the highly ordered step structure of the Co catalyst, straight nanoribbons with high aspect ratio (>100) are formed. Analysis suggests...

Title: Anomalous Stability of Graphene Containing Defects Covered by a Water Layer as Featured In: Anomalous Stability of Graphene Containing Defects Covered by a Water Layer †

The background shows a water layer on the graphene containing Stone–Wales and double vacancy defects. The structural and electronic properties of the systems have been studied by density functional tight-binding method, to understand graphene's stable electronic characteristics. Defects are inevitably present in graphene and can alter its properties and thus its applications. Interestingly, we ...
