in this research, a new technetium-99m generator has been developed with addition of cerium oxide to alumina column.  the adsorption behaviors of 99mo in the form of molybdate and 99mtc in the form of pertechnetate on ceo2/al2o3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using al2o3. ceric ions were selected as an addit...

The decomposition of ammonium heptamolybdate was investigated by in situ XAFS and in situ XRD to elucidate the influence of different atmospheres on the products formed the formation of different decomposition products and various intermediates is described in detail.

The state of the electrochemical behaviour Al electrode in aqueous solutions containing Na2MoO4 + H3PO4 chitosan was investigated by methods currentless chronopotentiometry, chronoamperometry, optical and scanning electron microscopy. modification surface polymolybdate phosphate layers carried out a potentiostatic mode potentials range from ?1 to ?3 V polarization time (from 15 90 min). element...

Estrogen receptors from rat uterus and human breast carcinoma were analyzed by diethylaminoethyl-cellulose chromatography. Cytosols which had been incubated for short periods of time demonstrated a single discrete elution peak, indicating a single ionic form, while cytosols incubated for longer periods of time generated a second ionic form of receptor. Addition of cations to cytosols also promo...

After La2Mo2O9 (LMO), Cu-substituted LMO (LCuMO), and CuMoO4 (CuMO) powders were prepared by complex polymerization method or oxide mixing method, their antiviral antifungal activities evaluated. The obtained samples having a crystal structure of either with specific surface area 3.0–6.0 m2/g. These exhibited almost equal activity against bacteriophage Qβ, whereas CuMO was found to have the hig...

A series of molybdate, MoO4(2-), salts have been studied using solid-state 95Mo NMR spectroscopy at applied magnetic field strengths of 11.75, 17.63 and 21.14 T. In contrast to previous investigations, the principal components of the Mo shielding and EFG tensors have been obtained, as well as their relative orientations. At the fields employed, the anisotropic Mo shielding and quadrupolar inter...

Structure-activity relationship has been one of the main topics of research on catalysts all the time. Component and structure are the two moieties governing the performance of solid materials as catalysts. Multicomponent bismuth molybdates are well known catalysts for propene oxidation but pure crystalline phases of bismuth molybdate are inactive for the reaction. We have designed mesostructur...

This paper summarizes our work performed with glucocorticoid-binding complexes in molybdate-stabilized cytosol prepared from 32P-labeled L-cells. In our early work, we showed that cytosol prepared from 32P-labeled L-cells contains two phosphoproteins (a 90 and a 98-100 kdalton protein) that elute from an affinity resin of deoxycorticosterone agarose in a manner consistent with the predicted beh...

The increase in the cost of fertilizers and their low efficiency has led, through nanotechnology, to generation new innovative products that are sustainable improve productivity crops. Therefore, objective present study was evaluate efficacy a molybdenum nanofertilizer compared two conventional (chelate sodium molybdate) applied via foliar combined with soil fertilization NH4NO3 relation Nitrog...
