Protein recovery by selective separation using ceramic membranes

Selective separation of HIV-Tat protein using functionalized stacked microfiltration membranes: Enhancement of flux and recovery of protein

Affinity separation using functionalized microfiltration (MF) membranes provides a hydrodynamically favorable and cost-effective alternative to conventional column chromatography for the separation and purification of a specific protein from mixture of proteins. This type of separation in MF membranes is carried out by functionalizing the membrane with a suitable ligand containing specific inte...

Dense Ceramic Membranes for Hydrogen Separation

In the 1980s and 1990s, the development of oxygen ion conductors for solid electrolytes, as well as mixed oxygen–electron conductors as electrodes for solid oxide fuel cells, brought scientists to envision a possibility of mixed-conducting oxygenpermeable ceramic membranes. Today this field is well established, and ceramic membranes are close to implementation in processes for oxygen extraction...

Dense Ceramic Membranes for Hydrogen Separation

Novel cermet (i.e., ceramic-metal composite) membranes have been developed for separating hydrogen from product streams that are generated during coal gasification, methane partial oxidation, and watergas shift reactions. The hydrogen permeation rate in the temperature range of 600-900°C has been measured for three classes (ANL-1, -2, and -3) of cermet membranes. ANL-3 membranes provided the hi...

Supported Dense Ceramic Membranes for Oxygen Separation

Gas transport and separation with ceramic membranes. Part II. Synthesis and separation properties of microporous membranes

Non-supported microporous silica (amorphous) and titania thin films were made by the polymeric gel route. The titania system consisted of particles smaller than 5 nm. Reproducible modification of supported y-alumina films with silica demands a strict control of every modification step. Silica films of 3060 nm thickness on top of and presumably partly inside the y-alumina film were realised. The...
