Gas membrane separation technology is a kind of mixed gas with low energy consumption, simple equipment, easy operation and no influence on the environment. Due to special properties graphene oxide (GO) membrane, GO has become research hotspot technology. In this paper, A critical thickness demonstrated: when less than 600nm, conductance inversely exponential thickness, but proportional thicker...

This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...

Mechanical properties of a nanomechanical resonator significantly impact the performance resonant Nano-electromechanical system (NEMS) device. We study mechanical suspended membranes fabricated out low-pressure chemical vapor deposited silicon nitride thin films. doubly-clamped with thickness less than 50 nm and length varying from 5 to 60 μm. The elastic modulus stress in were measured using A...

The gas-liquid membrane contactor (GLMC) is a promising alternative gas absorption/desorption configuration for effective carbon dioxide (CO2 ) capture. The physicochemical properties of membranes may synergistically affect GLMC performances, especially during the long-term operations. In this work, commercial polypropylene (PP) and polyvinylidene fluoride (PVDF) hollow fiber (HF) membranes wer...
