Bifunctional Characteristics of Al2O3 supported Ni in the HI Decomposition of Sulfur-Iodine Process

MATEC Web of Conferences, 2016
The Sulfur-Iodine process is in need of catalytic reactor for HI decomposition because the HI decomposition reaction rate is very slow. Nickel as an alternative catalyst for platinum was investigated in this study.

Hydrogen bubble nucleation by self-clustering: Density Functional Theory and statistical models studies using tungsten as a model system

, 2017
Low-energy hydrogen irradiation is known to induce bubble formation in tungsten, while its atomistic mechanisms remain little understood. Using first-principles calculations and statistical models, we studied the self-clustering behavior of hydrogen in ...

Modelling ultrasound waves bubble formation in ethanol/ethyl acetate azeotrope mixture [PDF]

E3S Web of Conferences, 2019
The separation of an azeotropic mixture such as ethanol/ethyl acetate in distillation process can be enhanced by ultrasound wave. The application of ultrasound wave creates bubble cavitation in the mixture and shifts the vapour-liquid equilibrium ...

Adhesion Properties of Hydrogen on Sb(111) Probed by Helium Atom Scattering

, 2016
We have carried out a series of helium atom scattering measurements in order to characterise the adsorption properties of hydrogen on antimony(111). Molecular hydrogen does not adsorb at temperatures above 110 K in contrast to pre-dissociated atomic ...
