A thin-film balance employing either a Sheludko capillary or a Mysels-inspired porous-medium film holder provides a direct measurement of disjoining-pressure isotherms in free, liquid thin films. However, each film holder suffers its own distinct disadvantages spanning non-uniform and slow liquid exchange, a limited range of measurable disjoining pressures, an inability for reuse, and a require...

Hugoniot data for oligoclase and microcline to 670 and 580 kb and release adiabat data for oligoclase were obtained by means of the inclined mirror and immersed-foil-reflected-light techniques, respectively. Oligoclase and microcline have Hugoniot elastic limits in the range of 40-55 and 80-85 kb. These limits increase slightly with increasing driving shock pressure. Above the elastic limit, ex...

FeTi-based hydrides have recently re-attracted attention as stationary hydrogen storage materials due to favorable reversibility, good sorption kinetics and relatively low costs compared alternative intermetallic hydrides. Employing the OpenCalphad software, thermodynamics of (FeTi)1−xHx (0 ≤x≤ 1) system were assessed a key basis for modeling hydrogenation alloys. New thermodynamic data acquire...

Design methods with predictive properties modeling are paramount tools to explore the vast compositional field of multicomponent alloys. The applicability an alloy as a hydrogen storage media is governed by its thermodynamic properties, which can be represented pressure-composition-temperature (PCT) diagrams. Therefore, prediction PCT diagrams for alloys fundamental design optimized application...

This communication reports the surface pressure (pi) versus area per molecule (A) isotherm characteristics of the mixed films of 9-phenyl anthracene (PA) in stearic acid (SA) and polymethyl methacrylate (PMMA) matrices, at the air-water interface. The mixed Langmuir films at the air-water interface have been observed to be easily transferred onto solid substrates to form uniform Langmuir-Blodge...

A process model was developed to simulate elemental mercury sorption by activated carbon in three distinct beds, namely a confined, a semi-fluidized, and a fluidized bed. The model involved the coupling of a kinetic model based on the mechanisms of surface equilibrium and external mass transfer, and a material balance model based on the tank-in-series approach. For surface equilibrium, three di...

The measurement of hydrogen induced changes on the electronic structure transition metal oxides by X-ray photoelectron spectroscopy is a challenging endeavor, since origin cannot be unambiguously assigned to hydrogen. H-induced in tungsten trioxide have been known for more than 100 years, but are still being controversially debated. controversy stems from difficulty disentangling effects due hy...
