graphene, after its first production in 2004 have received lots of attentions from researchers because of its unique properties. high mobility, high sensitivity, high selectivity and high surface area make graphene excellent choice for bio application. one of promising graphene base device that has amazingly high sensitivity is graphene field-effect transistor (gfet). this review selectively su...

The progress of nanotechnology has prompted the development novel marine antifouling coatings. In this study, influence a pristine graphene nanoplatelet (GNP)-modified surface in cyanobacterial biofilm formation was evaluated over long-term assay using an vitro platform which mimics hydrodynamic conditions that prevail real environments. Surface characterization by Optical Profilometry and Scan...

To improve the performance of polyether ether ketone matrix (PEEK) in hard tissue repair and replacement applications, we fabricated graphene nanoplatelet (G) reinforced PEEK with different filler weight concentrations (0.1%–5%) through injection moulding. The mechanical properties, surface morphology, chemical composition thermal stability composites have been characterized. biocompatibility h...

because of production process and constrains conditions, circular graphene sheet may be opposed to structural defect and pin hole, respectively. some of the defects and pin hole on a circular graphene sheet can be considered as an eccentric hole on the sheet. hence, analyzing behavior of circular graphene sheet with an eccentric hole is important. free vibration of an eccentric annular graphene...

We report on the enhanced thermoelectric properties of selenium (Se) doped bismuth telluride (Bi(2)Te(3-x)Se(x)) nanoplatelet (NP) composites synthesized by the polyol method. Variation of the Se composition within NPs is demonstrated by X-ray diffraction and Raman spectroscopy. While the calculated lattice parameters closely follow the Vegard's law, a discontinuity in the shifting of the high ...

Tin-based chalcogenide semiconductors, though attractive materials for photovoltaics, have to date exhibited poor performance and stability for photoelectrochemical applications. Here, a novel strategy is reported to improve performance and stability of tin monosulfide (SnS) nanoplatelet thin films for H2 production in acidic media without any use of sacrificial reagent. P-type SnS nanoplatelet...

In this study, the impact of nanofluid use in solar-thermoelectric generators (Solar-TEG) on thermal performance is investigated through analysis and simulation methodology. For conventional cooling analysis, we air as a coolant graphene nanoplatelet aqueous nanofluids (GNAN) for cooling. We make comparison between traditional to find best performance. GNAN at dispersion 0.025, 0.05, 0.075, 0.1...
