A novel non-plasticized nano-porous hybrid inorganic-organic polymer inclusion membrane (PIM) was synthesized, characterized, and evaluated as an anion exchange for application in electrogenerative processes to recover Pd2+ ions. Ionic liquids 1-ethyl-3-me­thyl­imidazolium chloride (EMIM-Cl) 1-butyl-3-methylimidazolium (BMIM-Cl) were used the carrier molecules polymeric network of PIM enhance p...

Membrane gas–liquid contactors have been developed to reduce the capital cost and energy consumption of conventional CO2 absorption stripping columns. As a hybrid technology membrane separation amine absorption, these units can improve gas process by generating 400–1500% greater mass transfer area per unit volume leading smaller equipment sizes. Regeneration occur within contactor below boiling...

The performances of two-phase polymer-liquid PEBAX®/polyethylene glycol (PEG) and three-phase polymer-liquid-solid PEBAX®/PEG/MWNT thin film composite membranes for CO2 and CH4 permeation were studied. The effect of temperature and MWNT/PEBAX® ratio on single gas (CO2 and CH4) permeability was investigated. The permeat...

Catalytic membrane ozonation is a hybrid process that combines filtration and catalytic ozonation. The deposited with an appropriate solid material acts as catalyst. As consequence, the contactor can act simultaneously (i.e., improving transfer/dissolution of gaseous ozone into liquid phase), well reactor oxidizing organic compounds). It be used in water wastewater treatment limiting disadvanta...

Using liquid membrane and, in particular, supported liquid membrane (SLM) is a novel method of separation in comparison to other methods such as adsorption, extraction and ion exchange. SLM is a combination of simultaneous extraction and disposal whose high efciency and capability is proven by many studies. So far, many researchers have utilized SLM in various scientifc...

Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main c...

this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

Abstract The nucleolus is a membrane-less organelle sequestered from the nucleus by liquid droplet formation through liquid–liquid phase separation (LLPS). It plays important roles in cell homoeostasis its internal thermodynamic changes. Reversible nucleolar transitions between coalescence and dispersion are dependent on concentrations, conformations interactions of molecular droplet-forming co...
