In the present work, adsorption of mercaptopurine (MP) drug on T4,4,4-graphyne sheet is examined by using density functional theory to explore the feasibility of T4,4,4-graphyne based sensor. The most stable configuration, charge transfer, adsorption energy, electronic band structures, and density of states are determined. It is found that weak physical adsorption with small charge transfer […]
AbstractOptical properties of carbon nanostructures produced by laser ablation method in different liquid environments have been studied experimentally. In this work we used a 7 ns fundamental wavelength of pulsed Nd:YAG laser at 1064 nm and 10 Hz repetition rate to produce carbon nanostructures including graphene in distilled water, acetone, alcohol, and CTAB. Structure and morphology of carbon […]
AbstractEffects of low-intensity UV treatment on the optical constants of red BS dye-doped polymethyl methacrylate (PMMA) film including refractive index, extinction coefficient, real and imaginary parts of dielectric constant, band gap energy, Urbach energy, and refractive index dispersion parameters are measured and calculated. Changes in optical constants mainly occurred in the UV–VIS range. Red BS […]
