In this study, we propose a novel approach to prepare few-layer graphene (FLG) dispersions, which is realized by exfoliating natural graphite flakes in a surfactant aqueous solution under hydrothermal treatment and liquid-phase exfoliation. In order

Graphene is prepared from natural graphite flakes by solvent dispersion and short-sonication time. In this study, we exfoliate few-layer graphene (FLG) directly in ethanol without adding high boiling point solvents, surfactants or polymers. Diverse c

We present a semiclassical approach based on recently reported Fermi velocity either graphene [1] and silicene [2] to explore the energy gap and band dispersion when graphene (silicene) is laterally confining at nanometer size, i.e., graphene nanorib

The values of the constant accessories are huge importance to calculate the hydraulic losses in a pipeline system when a fluid is transported, i.e., the flow rates, diameters, lengths and load losses can be determined in sections considering the char
