asymmetrically mixed matrix matrimid-mil-53 membranes with silicone cover layer were fabricated. for better understanding of membrane fabrication process, three main parameters of fabrication, matrimid concentration, silicone concentration and weight percentage of metal organic framework (mil-53) particles, were optimized by an experimental design method. cross-section sem images were used to s...
We have fabricated and characterized a novel superhydrophobic system, a meshlike porous superhydrophobic membrane with solid area fraction Φ(s), which can maintain intimate contact with outside air and water reservoirs simultaneously. Oscillatory hydrodynamic measurements on porous superhydrophobic membranes as a function of Φ(s) reveal surprising effects. The hydrodynamic mass oscillating in p...
Phase separation simulation study related to cellulose acetate-water-acetone has been done. Results show that porous asymmetric and symmetric membranes can be produced by changing the nonsolvent concentration or by the drying conditions without altering the polymer content using dry-casting process. Dry-casting process is the process in which complete evaporation of solvent and nonsolvent takes...
Structural health monitoring of porous materials such as concrete is becoming a major component in our resource-limited economy, as it conditions durable exploitation of existing facilities. Durability in porous materials depends on nanoscale features which need to be monitored in situ with nanometric resolution. To address this problem, we put forward an approach based on the development of a ...
