Witryna1 lis 2004 · The particle size distributions of PVP and β-CD stabilized Ag colloids in the presence of methanolic NaOH under different synthesis method were presented in Table 1. The particle size decreased with increasing molar ratio of stabilizer: AgNO 3 from 1 to 150 in both the stabilizer and the synthesis method.

Witryna28 cze 2024 · The size and the shape of the synthesized Fe 3 O 4 NPs by both NH 4 OH and NaOH are characterized using FESEM/EDX and TEM, as given in Fig. 2. The results of FESEM and TEM images indicated that Fe 3 O 4 NPs attained a spherical shape using NH 4 OH, while cubic shape was observed when using NaOH. Witryna13 kwi 2024 · The sum of H 2 O-P o, NaHCO 3-P o and NaOH-P o can be expressed as bioavailable organic phosphorus (Bio-P o). They are organic phosphates in the soil that can be enzymatically hydrolyzed [ 11 ]. The concentrations of Bio-P i and Bio-P o in the rhizosphere soils in the WLFZ were 90.36 ± 34.20 and 34.65 ± 12.18 mg/kg, … greenpathref
