WebNov 7, 2024 · Abstract We have proposed an optimized homogeneous precipitation method for the synthesis of spherical and well-dispersed pure Ln2O2SO4 (Ln = Gd, Ho, Dy and Lu) nanoparticles (NPs) using synthesized lanthanide sulfates and urea as starting materials. Ln2O2SO4 NPs can be easily transformed to Ln2O2S by reduction under H2 flow at … WebIntegrating Factors. Some equations that are not exact may be multiplied by some factor, a function u (x, y), to make them exact. When this function u (x, y) exists it is called an integrating factor . It will make valid the following expression: ∂ (u·N (x, y)) ∂x = ∂ (u·M (x, y)) ∂y. There are some special cases:
