ABA triblock copolymer-based model networks in the bulk: Effect of the number of arms on microphase behavior
(2005)The microphase separation behavior in the strong segregation limit of model networks based on cross-linked ABA triblock copolymers in the bulk was investigated by calculating analytically the Gibbs free energies of the ...

Ambiguous Role of Growth-Induced Defects on the Semiconductor-to-Metal Characteristics in Epitaxial VO2/TiO2 Thin Films
(2018)Controlling the semiconductor-to-metal transition temperature in epitaxial VO2 thin films remains an unresolved question both at the fundamental as well as the application level. Within the scope of this work, the effects ...

Attraction of iodide ions by the free water surface, revealed by simulations with a polarizable force field based on drude oscillators
(2005)Recent theoretical and experimental studies have shown that polarizable anions, such as iodide and bromide, preferentially accumulate close to the surface of electrolyte solutions. This finding is in sharp contrast to the ...

Comparison of spectral and finite element methods applied to the study of the core-annular flow in an undulating tube
(2002)A Galerkin/finite element and a pseudo-spectral method, in conjunction with the primitive (velocity-pressure) and streamfunction-vorticity formulations, are tested for solving the two-phase flow in a tube, which has a ...

Dissecting the stabilization of iodide at the air-water interface into components: A free energy analysis
(2006)Recent experiments and simulations show that large chaotropic anions favor solvation at the water surface, mainly due to induction interactions dominated by ionic polarizabilities. We compare the solvation free-energy ...

Effects of W6+ doping of TiO2 on the reactivity of supported Rh toward NO: Transient FTIR and mass spectroscopy studies
(1997)The transient adsorption and dissociation of NO over Rh supported on undoped and W6+-doped TiO2 in the temperature range of 25-450°C has been studied by FTIR and mass spectroscopy. It was found that at 25 °C three kinds ...

Initial/final state selection of the spin polarization in electron tunneling across an epitaxial FeGaAs (001) interface
(2007)Spin dependent electron transport across epitaxial FeGaAs (001) interfaces has been investigated using photoexcitation techniques. Spin filtering is observed in the forward bias regime and its sign is switched by using ...
