This review summarizes design strategies for nanoporous state-of-the-art BCP separation membranes, their preparation, device integration and use water purification.
Polymer-based membranes have advanced or novel functions in the various membrane separation processes for liquid and gaseous mixtures, such as gas separation, pervaporation (PV), reverse osmosis (RO), nanofiltration (NF), ultrafiltration (UF), microfiltration (MF), other critical applications of water purification, solvent concentration, recovery [...]
This paper deals with the purification of four proteins from Euphorbia characias latex, a copper amine oxidase, a nucleotide pyrophosphatase/phosphodiesterase, a peroxidase, and a purple acid phosphatase. These proteins, very different in molecular weight, in primary structure, and in the catalyzed reaction, are purified using identical preliminary steps of purification and by chromatographic m...
Membrane technology is a sustainable process of molecular separation and purification in the chemical pharmaceutical industries, with lower energy consumption than traditional thermal methods.
Organic solvents are widely used as reaction media and/or for the separation and purification of synthetic products in chemical pharmaceutical industries [...]
The use of state-of-the-art separation tools from the pharmaceutical industry for addressing intractable separation problems from academic synthetic chemistry is evaluated, showing fast and useful results for the resolution of complex mixtures, separation of closely related components, visualization of difficult to detect compounds and purification of synthetic intermediates. Some recommendatio...
anthrax is one of the important zoonose disease between human and cattle. bacillus anthracis is a gram- positive bacterium which its tripartite protein toxin contains protective antigen (pa), edema factor (ef) and lethal factor (lf) and a poly d- glutamic acid capsule. a recent resurgence of interest in b.anthracis resulted in improved methods for production, separation and purification of the ...
