First, americium (241Am) nitrate solution was coated on a platinum foil, the solution was evaporated and the residue converted by annealing to americium dioxide (AmO2).
The sample was prepared as follows: first plutonium nitrate solution was coated on a platinum foil of about 0.5 cm2 area, the solution was evaporated and the residue was converted into plutonium(IV) oxide (PuO2) by annealing.
For comparison, nanoWO3|Ni(NO3)2 and nanoWO3|[Ti(O iPr 4] were prepared by spin coating nickel II) nitrate hexahydrate (Ni(NO3 2 ⋅6 H2O, 30 μL of 10 m m in 2-methoxyethanol; BDH Chemical) and a titanium isopropoxide solution ([Ti(O iPr 4], 30 μL of 20 m m in toluene; 97 %; Sigma Aldrich) on nanoWO3 according to the same procedure.
First plutonium-239 nitrate (239PuNO3) solution was coated on a platinum foil of about 0.5 cm2 area, the solution was evaporated and the residue was converted into plutonium dioxide (PuO2) by annealing.
In 1885 R.S. Penniman, an American, found a solution to the problem by coating the ammonium nitrate with a small percentage of paraffin, or some similar substance, prior to use.
Nanoparticles (10 80 nm, with or without polysaccharide coating), or silver nitrate (AgNO3) at concentrations of 100, 50, 25, and 12.5 μg/mL were evaluated for efficacy using a plaque reduction assay.
To prepare the coating solution, aluminum nitrate nonahydrate (Al(NO3 39H2O; Sigma-Aldrich, St . Louis MO, USA) and ammonium dihydrogen phosphate ((NH4 H2PO4; Sigma-Aldrich, St . Louis MO, USA) were dissolved separately in 10 mL of a mixed solvent consisting of distilled water, 1-butanol, and acetic acid.
In order to prepare the AlF3 coating solution, aluminum nitrate nonahydrate (Al(NO3 39H2O; Sigma-Aldrich, St . Louis MO, USA) and ammonium fluoride [NH4F] (Sigma-Aldrich, St . Louis MO, USA) were dissolved in 10 ml of a mixed solvent consisting of distilled water, 1-butanol, and acetic acid.
