Preparation and characterization of porous polyethersulfone nanofiltrationmembranes via combined phase separation method for water desalination

Jahanbakhsh Asl H., Soltanieh M., Sharif University of Technology, IR

In this work combined thermally induced phase separation (TIPS) and nonsolvent induced phase separation (NIPS), were used to fabricate nanofiltration membranes for water desalination at low pressures. Polyethersulfone (PES) flat-sheet membranes were successfully prepared by [...]

Global Gas Flaring -The Energy Waste with Serious Environmental Impacts: Case Study of Iran

Soltanieh M., Zohrabian A., Gholipour M.J., Sharif University of Technology, IR

Gas flaring in oil production and oil and gas refining is a major environmental issue with great energy and economic loss. In this paper the global gas flaring and its adverse environmental impacts have been [...]

H2 purification with PVDF/GTA blended membranes

Rabiee H., Soltanieh M., Mousavi S.A., Ghadimi A., Sharif University of Technology, IR

In this study, poly(vinylidene fluoride) (PVDF) and Glycerol Triacetate (GTA) have been selected as the main blending materials in order to fabricate membranes with a high separation ability for CO2/H2. GTA as a plasticizer possesses [...]

Preparation and characterization of SAPO-34 nanoparticles-mixed matrix membranes (MMM) via combined phase separation method for CO2/CH4 gas separation application

Jahanbakhsh Asl H., Soltanieh M., Azadi R., Sharif University of Technology, IR

Mixed matrix membranes (MMM) comprising of SAPO-34 zeolite nanoparticles in polyethersulfone (PES) matrix were fabricated via combined TIPS/NIPS phase separation method, which is critical for membrane performance, were synthesized and characterized. The performance of the [...]

Application of Sugimoto model on particle size prediction of colloidal TiO2 nanoparticles

Mehranpour H., Askari M., Ghamsari M.S., Farzalibeik H., Sharif University of Technology, IR

This can be provided by understanding the nucleation and growth mechanism of nanoparticles. In this paper, the nucleation and the growth of TiO2 nanoparticles were studied with Sugimoto model, in a homogeneous closed system which [...]
