In this study, we present straightforward methods to produce large-area GO sheets with fewer defects on the basal plane and for addressing the problems associated with dispersing reduced GO nanosheets in organic solvents for applications. [...]
We discover that piezoelectric effects can be engineered into nonpiezoelectric graphene through the selective surface adsorption of atoms. Our calculations show that doping a single sheet of graphene with atoms on one side results in [...]
Developing flexible electronic materials with the ability to amplify signals is a major challenge for bioelectronics. The next step in developing an active nervous system calls for a flexible electronic material that produces a signal [...]
Graphene is a flat monolayer of carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice, and is a basic building block for graphitic materials of all other dimensionalities. Electrons of graphene behave as Dirac [...]
Graphene is a flat monolayer of carbon atoms whose extraordinary properties are to revolutionize the performance of many technological applications. Unfortunately there is very little understanding of how the properties of graphene change in its [...]
We successfully developed the Bi-GCPE electrode for the determination of Cd2+ and Pb2+ in real sample such as sea bass fish tissue and undulated surf clams tissue by square wave anodic stripping voltammetry. The detection [...]

Scalable growth of graphene has been demonstrated by chemical vapour deposition (CVD) using copper-based catalyst and ethylene precursor. Here, we present our ethylene-based CVD synthesis method of graphene along with our observation of early and [...]
We have developed methods of CVD processing which are suitable for the industrial production of graphene foam. By optimizing the parameters of CVD growth and choosing the proper nickel support structure, we have tuned the [...]
We have discovered a new way of making graphene using specific catalyst stagger. The catalyst staging mechanism is believed to prevent the full adsorption of C free radicals, which forms tubular shape products. The specific [...]
In this study and development,it challenged in synthesizing of flexible CNT having few layers graphene and showing the excellent physical property different from graphite fibers. In this study,raw material calcined and cobalt acetylacetonato were mixed [...]

The paper reports on a Ni based electrical contacting technology to graphene that is simple and effective and can be adopted by laboratories lacking high grade infrastructure. The graphene surface is masked, activated and then [...]
The registry of adjacent graphene layers grown on the C-terminated SiC surface has been reported to be dramatically different compared to graphene grown on the Si-terminated SiC(0001) surface. Whereas Si-face graphene exhibits sharp spots in [...]
We examine the subband energy spectrum of a coupled symmetric Graphene double-quantum- dot system subject to Landau quantization in a normal magnetic eld. To formulate the dispersion relation, we construct the coupled double-dot Graphene Green`s [...]

We report direct imaging of thermal transport in single and few-layer graphene with approximately 50 nm lateral resolution using high vacuum scanning thermal microscopy. Images reveal low thermal resistance of areas of suspended graphene where [...]
