Synthesis of nano-porous molecular sieve from some natural materials
Zeolites due to their structures can be used as molecular sieves for purification of materials and solutions. Zeolites with PHI and SOD structure are so common and applicable for this purpose. Hydroxy sodalite and phillipsite are the more abundant members of zeolites which display good selectivity for very small molecules and some ions such as Sr, Pb, Zn, Cu and Rb. There is not any pure natura...

متن کاملMolecular Sieve Studies of Interacting Protein Systems
Studies of chemically reacting systems of macromolecules by conventional transport experiments are subject to inherent ambiguities. These uncertainties often prohibit an unequivocal determination of the explicit reactions which give rise to the average propexties being measured. Such difficulties may be circumvented with molecular sieve chromatography in which subunit dissociation curves are ob...

changed under ambient condition for at least 40 h, time to which these measurements were carried out. To investigate the absorption behavior as a function of time, the absorption spectrum at 100 OC was taken at regular intervals over 40 h for poled/cured A204/DR1. An absorption peak at A, , = 508 nm existed before poling/curing. After poling/curing &shifta to 493 nm with a decrease of absorbanc...
متن کاملMolecular Sieve Studies of Interacting Protein Systems
Highly purified preparations of D-aIIIiII0 acid oxidase were obtained by removal of high molecular weight components after purification by established procedures. Molecular sieve studies were carried out on the size characterization of the highly purified apoenzyme molecule. In the microgram per ml concentration range the apoenzyme was shown to dissociate to a subunit with a molecular Stokes ra...
