Three-dimensional hierarchical Prussian blue composed of ultrathin nanosheets was successfully synthesized by employing a self-aggregation and oriented attachment strategy. The unique structure highly increases the exposure of micropores and metal sites of Prussian blue to guests, thus significantly enhancing its hetero-catalysis and adsorption properties compared to cubic and commercial counte...

C-reactive protein (CRP) as it occurs in serum and in all but a very few pathological fluids is associated with a phosphorus-containing substance or substances of lipid character.' It can be obtained from the fraction of serum precipitable by 0.5 to 0.75 saturation with ammonium sulfate, following dialysis against dilute calcium chloride. The complex obtained by this procedure is insoluble in d...

To the Editor: We read with interest a paper on phospholipid analysis in this journal (1) but deferred comment until the publication of our own paper on the subject, which we believe contains relevant material (2). Sandhu refers to the formation of a Prussian blue complex as the result of a reaction between phospholipids and a chromogenic reagent containing molybdenum. Clearly this cannot be so...

introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...

Phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (P) forms to soluble and bioavailable P. The aim of the present study was to isolate P solubilizing bacteria from forest soils around the rock phosphate (RP) mine of Koh-e-SepidLar in Kohgiluyeh and Boyer Ahmad province and evaluate their ability in Sperber culture medium and wheat straw medium in the presen...

During a study of the energy-rich phosphorus compounds of higher plants, it became necessary to differentiate between ribose-3-phosphate and ribosed-phosphate. The only method available for distinguishing between these esters at low levels (quantities of 1 mg. or less) is that of Levene and Stiller (1). This method depends on the difference in the rate at which these compounds release their pho...

considering high alkalinity of iranian soils and lack of availability of some nutrients in those conditions, sulfur consumption is one approach to increase the availability of insoluble nutrients especially in calcareous and alkaline soils. effectiveness of sulfur depends on activity of sulfur oxidizing bacteria especially thiobacillus genus (t). in order to study the qualitative yield and morp...
