This study is about Complexes of Li doped silicon carbide nanotube with Thymine and Cytosine ingas phase and aqueous solutions. Li doped silicon carbide nanotube and its pyrimidine nucleobasecompounds were first modeled by Quantum mechanical calculations in gas phase and in water.Calculated binding energies indicated the stronger ability of thymine to functionalize silicon carbidenanotube than ...

Single phase Eu doped GdMnO3 ceramics were prepared using solid state reaction route. Several different characterization techniques were used to investigate the structural and magnetic properties of the samples, including X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX) and Vibrating Sample Magnetometer (VSM). All samples indicated single p...

Adsorption of NO2 molecule on pristine and N-doped TiO2 anatase nanoparticles have been studied using the density functional theory (DFT) technique. The structural properties (such as bond lengths and bond angles) and the electronic properties (such as density of states, band structures and atomic partial charges) have been computed for considered nanoparticles. The result...

In this study, Eu-doped CdSe nanoparticles with variable Eu3+ content were synthesized by a simple sonochemical method. Eu3+ substitution into the structure of CdSe resulted in a material with new physical properties, composition and morphology. The synthesized nanoparticles were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscop...

The phase diagram for hole-doped cuprates is discussed. By examining some recent inelastic neutron scattering data obtained on hole-doped cuprates we conclude that the coherent gap in hole-doped cuprates has most likely the magnetic origin and scales with Tc, on average, as 2∆c/kBTc = 5.4.

A novel strategy to synthesize nitrogen (N) and sulfur (S)-doped graphene (G) is developed through sulfate-reducing bacteria treating graphene oxide (GO). The N, S-doped G demonstrates significantly improved electrocatalytic properties and electrochemical sensing performances in comparison with single-doped graphene due to the synergistic effects of dual dopants on the properties of graphene.

The nonlinear coefficient and group velocity dispersion of a thulium-doped fiber near 2μm are evaluated via four-wave mixing. Nonlinearity of thulium-doped fiber can be used for the design of doped-fiber lasers in this spectral region.
