spinel-type of mno2 nanoparticles which successfully synthesized by a hydrothermal process, have a required capacity for lithium uptake from liquid resources. themost lithium adsorption capacity of 6.6 mmol/g of up to now was found to be an important limiting parameter for industrial applications. therefore, increasing uptake capacity of these ion sieves by studding the effect of six effective ...

Secondary aluminum dross as a solid waste can cause great harm to environment. However, it contains rich alumina oxide which is an ideal raw material for the preparation of molecular sieve. Therefore, optimal process was explored 4A sieve using secondary source and additional silicon source. The results show that prepared under conditions silicon/aluminum 2.0, crystallization temperature 95 °C ...

Colonic mucin was prepared by phenol-water partition extraction of th colonic mucosa, followed by ethanol precipitation of the water-soluble material, molecular sieve chromatography, and reductive sodium dodecyl sulfate-disc gel electrophoresis in an agarose-polyacrylamide gradient gel. Although this material as observed to be relatively homogeneous by physical criteria, it was shown to contain...

Neurophysin has been separated into seven distinct protein fractions. One of these components had no hormone-binding activity. The fractions that had hormone-binding activity were similar in amino acid composition: their cystine content was in the range 11.5-14.5%. The major component, neurophysin-M, was distinguished from the protein isolated by van Dyke by the presence of methionine and the a...
