The Prediction of Undersaturated Crude Oil Viscosity: An Artificial Neural Network and Fuzzy Model Approach

White paper on the future of plasma science in environment, for gas conversion and agriculture

“…Separation is based on differences in solubility and/or diffusivity and consequently permeability of the gases to be separated. Mixed matrix membranes, comprising embedded gas selective particles in a continuous polymeric matrix and operating at moderate temperatures (<300 °C), attract much interest for separation of CO 2 from exhaust gases . The dispersion of selective particles, metal organic frameworks (MOFs), enhances the separation properties resulting in increased selectivity and productivity.…”

Highly efficient helium purification through a dual-membrane system: insights from molecular dynamics simulations

“…Often high selectivity membranes indicate less gas permeation and vice versa . 43 Consequently, conventional porous materials still cannot meet the requirements of gas separation because of some deficiencies. 44 In this regard, the Robeson upper bound limit for a variety of membranes, shows the limited range of membranes’ performance in gas separation.…”

Molecular dynamics simulations of a hydrophilic MIL-160-based membrane demonstrate pressure-dependent selective uptake of industrially relevant greenhouse gases

“…Please do not adjust margins Please do not adjust margins large enough with respect to both the time of operation and materials' lifetime 4 . Pressure swing adsorption (PSA) was recently exploited for the removal of vapor-phase impurities and enrichment of usable gases 11,18,20,21,24,25 benefiting from low energy input and facile implementation at varied production scale 26,27 . Similarly, gas separations via microporous polymer membranes have been commercially employed for the oxygen enrichment of air, recovery of hydrogen from ammonia production process streams, and the upgrade of natural gas 28 .…”
