(3×3)R30°−(K+CO)coadsorption structure on Pt(111): Experiment and theory

THEORY, EXPERIMENT AND PRACTICE OF SLAG ATTACK OF REFRACTORIES

Penetration and dissolution mechanisms are reviewed for predominantly single-phase oxide, two phase oxide and oxide-carbon composite refractories by liquid silicate slags. Theoretical models of these processes, as well as static (sessile drop, dipping and crucible) and dynamic (rotating finger and rotary slag) experimental tests, along with their practical limitations are considered. Direct (co...

Electronic structure of aluminum nitride: Theory and experiment

We report the results of a vacuum ultraviolet (VIJV) study of single crystal and polycrystalline AlN over the range 4-40 eV and compare these with theoretical optical properties calculated from first principles using an orthogonalized linear combination of atomic orbit& in the local density approximation. The electronic structure of AIN has a two-dimensional (2D) character indicated by logarith...

Structure of polydisperse electrorheological fluids: Experiment and theory

Macroscopic properties of electrorheological (ER) fluids are often determined by the spatial arrangement of the suspended particles. We investigate the microstructure of polydisperse ER fluids at low concentrations in a DC electric field. Optical microscopy reveals that the particles with polydispersity in size or in both size and dielectric property are mixed in stable single particle width ch...

Structure of pyridazine in the S1 state: experiment and theory.

The molecular structure of pyridazine in the first electronically excited state (S(1)) is deduced from the combined use of resonance-enhanced two-photon ionization and mass-analyzed threshold ionization spectroscopic methods. The equation-of-motion coupled-cluster single and double (EOM-CCSD) calculation gives the distorted planar geometry for the most stable structure of the S(1) pyridazine. T...
