The reduced graphene oxide (RGO)/carbon double-coated 3-D porous ZnO aggregates (RGO/C/ZnO) have been successfully synthesized as anode materials for Li-ion batteries with excellent cyclability and rate capability. The mesoporous ZnO aggregates prepared by a simple solvothermal method are sequentially modified through distinct carbon-based double coating. These novel architectures take unique a...

Commercial 2D carbon materials are shown to be largely nanographite with a small percentage of single layer material present.

The Cancer is one of the world’s most devastating diseases. Doxorubicin (DOX) is an effective chemotherapeutic drug; however, its toxicity is a significant limitation in therapy. Due to the severe side effects of chemotherapy drugs, scientists have tried to load these drugs in nanocomposites. This paper describes a facile and low cost approach for preparation polymeric biodegradable nanohybrid ...

332 catalysts, storage devices, etc. Carbon is considered a rich family for nanoscale systems, and it exhibits extensive functionalities which depend on its structural and functional arrangements. But not all members of the carbon family have become relevant for application in modern society. The most promising research has focused on two-dimensional (2D) graphene-based systems, with an exponen...

Graphene, a two-dimensional honeycomb lattice of sp 2 hybrid carbon, exhibit combination of unique characteristics such as high thermal and electrical conductivity, excellent mechanical strength and very high specific surface area, which promises their great potential for various applications including nanoelectronics, catalysis, sensors, energy storage devices, polymer composites, lubricants a...

A mussel-inspired new interfacial ionic rectification device is fabricated using porous anodic alumina nanochannels and graphene oxide via dopamine polymerization. In addition, the rectification mechanism is elucidated based on the principles of physics and thermodynamics via finite element simulation and the results show that the interface distance and surface charge play a vital role in ion t...

Fluorescence intermittency or blinking is observed in nearly all nanoscale fluorophores. It is characterized by universal power-law distributions in on- and off-times as well as 1/f behaviour in corresponding emission power spectral densities. Blinking, previously seen in confined zero- and one-dimensional systems has recently been documented in two-dimensional reduced graphene oxide. Here we s...

Graphene-nanoparticle (NP) composites have shown potential in applications ranging from batteries to, more recently, tissue engineering. Graphene and NPs should be integrated into uniform free-standing structures for best results. However, to date, this has been achieved only in few examples; in most cases, graphene/NP powders lacking three-dimensional (3D) structure were produced. Here we repo...
