a feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. in the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by ftir and sem. the nanocomposite shows a high...

We investigated the chemical vapor deposition synthesis of Mo2C/graphene heterostructures on a partially wetted liquid copper surface, studied morphology resulting phases using electron and optical microscopy, determined rate-limiting step for growth Mo2C graphene. The crystals varied from center to edge substrate because change in Mo diffusion pathways owing variation thickness Cu substrate. T...

The two-dimensional form of carbon, graphene, shows remarkable electronic properties1,2 that could prove useful in applications such as ultrafast energyefficient transistors3,4 for computers and mobile devices, and as flexible transparent conductors for macroelectronic devices such as solar cells, display panels and electronic newspapers. However, to realize the technological potential of graph...

In this work, we present a detailed experimental study of pulse formation mechanism in an EDFL, hybridly mode-locked by use CVD monolayer graphene onto D-shaped optical fiber and nonlinear polarization rotation (NPR), under large intracavity dispersion influence (up to 100 times) ranging from 12.3 1382 m cavity lengths. Analyzing the spectral evolution, temporal soliton behaviors pulse, our res...

Graphene fiber-based supercapacitors are known as the potential energy resources for wearable/flexible electronics. However, increasing their specific capacitance and density remains a significant challenge. This paper indicates double layer of graphene nanosheets accompanied by pseudocapacitive behavior polyaniline to prepare composite fibers with high capacitive response. The polyaniline/grap...

The tantalizing prospect of harnessing the unique properties of graphene crumpled nanostructures continues to fuel tremendous interest in energy storage and harvesting applications. However, the paper ball-like, hard texture, and closed-sphere morphology of current 3D graphitic nanostructure production not only constricts the conductive pathways but also limits the accessible surface area. Here...

A polarization-insensitive graphene-assisted electro-optic modulator is proposed. The orthogonal T-shaped metal slot hybrid plasmonic waveguide allows the polarization-independent propagation of transverse electric field mode and complex mode. By introduction dual-layer graphene on ridge waveguide, modulation depths TE are 0.511 dB/µm 0.502 dB/µm, respectively. 3 dB bandwidth we have proposed a...

La0.7Ca0.3MnO3 (LCMO) thin films on (LaAlO3)0.3(Sr2AlTaO6)0.7 (001) [LSAT (001)] single crystal substrates have been prepared by high magnetic field assisted pulsed laser deposition (HMF-PLD) developed by ourselves. Uniformly sized and vertically aligned nanorod structures can be obtained under an applied high magnetic field above 5 T, and the dimension size of the nanorods can be manipulated b...
