one of the barriers during whey filtration using uf membrane is the fouling phenomenon of the membrane, which is caused by whey proteins. in this work, the uf membranes were prepared using polysufone (psf), dimethyl formamide (dmf), 1 wt.% poly vinyl pyrrolidone (pvp) and different concentrations of licl via phase inversion induced by immersion precipitation. the prepared membranes were charact...
The pore structure of three-dimensional scaffolds used in tissue engineering has been shown to significantly influence cellular activity. As the optimal pore size is dependant on the specifics of the tissue engineering application, the ability to alter the pore size over a wide range is essential for a particular scaffold to be suitable for multiple applications. With this in mind, the aim of t...
The combined effect of pore size and pore volume on the equilibrium adsorption capacity and the adsorption kinetics for a series of normal alkanes is determined. The selected adsorbents, activated carbon fibers (ACFs) and air activated phenolic fibers (AAPFs), possess a range of micropore sizes and have been thoroughly characterized in past work. For the normal alkane series, the lower surface ...
Baked ceramic aggregates (fritted clay, arcillite) have been used for plant research both on the ground and in microgravity. Optimal control of water and air within the root zone in any gravity environment depends on physical and hydraulic properties of the aggregate, which were evaluated for 0.25-1-mm and 1-2-mm particle size distributions. The maximum bulk densities obtained by any packing te...
