to determine the non-bonded interaction energies between naphthalene and b12n12 nano ring in different orientations and distances, geometry of molecules with b3lyp method and 6-31g* basis set optimized. also reactivity and stability of naphthalene alone and in the presence b12n12 nano ring checked. then calculated the nbo, nmr, freq, nics and muliken charge of naphthalene atoms alone and in the...

A power scalable thulium-doped fiber-amplifier-based supercontinuum (SC) laser covering the shortwave infrared region from 2 to 2.5 μm is demonstrated. The SC laser has an average power up to 25.7 W and a spectral density of >12 dBm/nm. Power scalability of the laser is proven by showing that the SC laser maintains a nearly constant spectral output, beam quality (M(2) measurements), and output ...

Abstract Protonic ceramic fuel cells (PCFCs) offer a convenient means for electrochemical conversion of chemical energy into electricity at intermediate temperatures with very high efficiency. Although BaCeO 3 - and BaZrO -based complex oxides have been positioned as the most promising PCFC electrolytes, design new protonic conductors improved properties is paramount importance. Within present ...

Electronic Raman scattering from high- and low-energy excitations was studied as a function of temperature, extent of hole doping, and energy of the incident photons in Bi2Sr2CaCu2O8+/-delta superconductors. For underdoped superconductors, short-range antiferromagnetic (AF) correlations were found to persist with hole doping, and doped single holes were found to be incoherent in the AF environm...

The interaction of a nitrosyl hydride (HNO) molecule with B12N12 nanocage was explored by means of density functional calculations. It was found that HNO prefers to be adsorbing on a boron atom of the cage with adsorption energy of -0.65 eV. This adsorption process significantly shifts the HOMO-LUMO gap (Eg) of the cage to lower energies, thereby reducing Eg of the cage from 6.84 to 2.45 eV. Ti...

We investigate the asymmetry between electron and hole doping in a 2D Mott insulator and the resulting competition between antiferromagnetism (AFM) and d-wave superconductivity (SC), using variational Monte Carlo calculations for projected wave functions. We find that key features of the T=0 phase diagram, such as critical doping for SC-AFM coexistence and the maximum value of the SC order para...
