Graphene oxide (GO) is a unique material due to its various functional groups involving unsaturated double bonds, epoxy/hydroxyl groups on the basal planes, and carboxylic acid groups at the edges. Thus, GO exhibits uniqueness compared to other carbon related materials (such as carbon nanotubes, graphene sheets and fullerenes) due to its pronounced potential of functionality alteration. The latter feature allows GO to b Read More

Different approaches to obtain metallic particles on graphene are discussed in this Review article and their applications in catalysis, electrocatalysis and surface enhanced Raman spectroscopy (SERS) are highlighted. Synthetic methods for well-dispersed metallic particles (Au, Ag, Pt, Pd, TiO2 and QDs) on graphene are summarized, and comparisons are made in their utilization in a plethora of applications with pure metallic particl Read More

In this mini review we discuss the interactions of polyaromatic hydrocarbons (PAHs) with graphene and the experimental approaches developed so far to create novel graphene/PAH hybrids and composite systems. The utilization of these systems in electrical, biomedical and polymer-reinforcement applications is described while special emphasis is given to environmental remediation issues.

Graphene based materials are at the center of academic attention lately. Studies have shown that graphene can be successfully combined with other materials, aiming to enhance electrical, thermal or mechanical properties. Herein, a comprehensive study of the most recent advances in the field of polymer non-covalent functionalization of graphene is presented. Solid state graphene/polymer nanocomposites are classified in Read More

Due to their unique structure, the optical and mechanical properties graphene and its derivatives (e.g. graphene oxide, reduced graphene oxide) have captured the attention of a constantly increasing number of scientists with regards to biomolecule sensing. This mini review focuses on one specific type of sensor, that consisting of graphene and polyelectrolytes. Polyelectrolyte-graphene nanocomposites exhibit outstanding d Read More

Carbon nanostructures and especially graphene oxide (GO) have attracted tremendous interest in the scientific community due to the potential utilization in numerous applications in the last decade.

Energy production and storage have become key issues due to the ever increasing demand of electricity in modern days. Rechargeable batteries are recognized as the primary power sources for applications from portable electronic devices to electric vehicles. Recently, there has been a growing interest in investigating graphene nanocomposite materials for various energy storage applications, such as electrodes in lithiu Read More

In the present review article we discuss the progress that has been thus far achieved towards producing graphene nanoribbons (GNRs) with predefined dimensions and, therefore, electronic properties, by using bottom-up approaches. Some selected, representative top-down strategies are also reviewed. GNRs are graphitic carbon-based materials having nano-scale dimensions and semiconducting or metallic electronic Read More
