Aluminophosphate-5 (AlPO4-5) nano-pore zeolite was synthesized. The effect of alteration in precursor gel preparation on the morphology of zeolite was studied. The effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of AlPO4-5 zeolite been studied. A hydrothermal synthesis has been used to produce nano-pore Aluminophosphate-5 c...

In this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (II) sulfate as metal precursor and polyvinylpyrrolidone k-30 (PVP K-30) as surfactant agent. The reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. Characterization o...

Copper-manganese oxide catalysts are prepared with an atomic ratio of Cu/Mn=2/1 using a coprecipitation procedure under air atmosphere. The time of aging, i.e., the time that precipitate remains in contact with the precipitating medium, has been varied from 0 (for unaged precursor) to 300 minutes and the effect of precipitate aging time in each atmosphere upon the structure and morphology of di...

To explore whether or not the gossypol varied in cottonseed by-products affect rumen degradability and fermentation efficiency, an vitro cumulative gas production experiment was applied with mixed microorganism to compare characteristics of whole (WCS, n = 3 samples), meal (CSM, hull (CSH, 2 samples). The five-replicate per sample incubation time continuously lasted for 0.5, 1.5, 3, 6, 12, 24, ...

b-cell lymphoblastic lymphoma (b-lbl) is an uncommon subtype of pediatric non-hodgkin lymphoma (nhl) which rarely involves the skin primarily. the positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-d: -glucose integrated with computed tomography (18f-fdg pet/ct) scan findings of a 8-year-old boy with cutaneous b-lbl were presented. pet/ct scan demonstrated mild fdg uptake in the ...

abstract introduction connection of socioeconomic status measures (such as income and education and parental addiction) to childhood leukemia are likely to vary with place and time. the aim of this study was to assess the relation between socioeconomic status and childhood leukemia. materials and methods a case- control study conducted on 86 case of acute lymphoblastic leukemia age 0-14 years i...
