Hydrate formation/dissociation of natural gas in (diesel oil + water) emulsion systems containing 3 wt% anti-agglomerant were performed for five water cuts: 5, 10, 15, 20, and 25 vol%. The natural gas solubilities in the emulsion systems were also examined. The experimental results showed that the solubility of natural gas in emulsion systems increases almost linearly with the increase of press...

We have studied the dispersion and exfoliation of four inorganic layered compounds, WS2, MoS2, MoSe2 and MoTe2 in a range of organic solvents. The aim was to explore the relationship between the chemical structure of the exfoliated nanosheets and their dispersability. Sonication of the layered compounds in solvents generally gave few-layer nanosheets with lateral dimensions of a few hundred nan...

Canadian Biosystems Engineering/Le génie des biosystèmes au Canada. 53: 8.1 8.18. One of the major barriers to the use of biogas as an alternative renewable energy source is the presence of siloxanes. At combustion temperatures, siloxanes ar...

A fully atomistic simulation study is reported to provide mechanistic insight into the superior performance experimentally observed for a polymer membrane (Carta et al., Science, 2013, 339, 303-307). The membrane namely PIM-EA-TB is produced by a shape-persistent ladder polymer of intrinsic microporosity (PIM) with rigid bridged bicyclic ethanoanthracene (EA) and Tröger's base (TB). The simulat...

A novel set-up for monitoring the gas diffusion process in polymers has been developed. This is based on performing neutron radiography and tomography of polymeric materials under high pressures gas. Information about absorption kinetics supercritical CO2 was obtained. Additionally, solubility, diffusivity, macroscopic changes dimensions samples can be in-situ obtained through developed measure...

Organic matter (OM) uptake in cloud droplets produces water-soluble secondary organic aerosols (SOA) via aqueous chemistry. These play a significant role in aerosol properties. We report the effects of OM uptake in wet aerosols, in terms of the dissolved-to-gas carbon dioxide nucleation using molecular dynamics (MD) simulations. Carbon dioxide has been implicated in the natural rainwater as wel...

Thermodynamic analysis of III-V semiconductor alloys grown by metalorganic vapor phase epitaxy Toshihiro Asai and David S. Dandy Dept. of Chemical Engineering, Colorado State University, Fort Collins, Colorado 80523-1370 A thermodynamic analysis has been applied to systematically study III-V semiconductor alloy deposition, including nitrides grown by metalorganic vapor phase epitaxy. The predic...

Bubbles introduced to the arterial circulation during invasive medical procedures can have devastating consequences for brain function but their effects are currently difficult to quantify. Here we present a Monte Carlo simulation investigating the impact of gas bubbles on cerebral blood flow. For the first time, this model includes realistic adhesion forces, bubble deformation, fluid dynamical...
