Witryna3 wrz 2024 · The F of a drug impurity was determined by preparing stock solutions from weighed portions of drug and impurity (± 0.05 mg accuracy). Stock solutions were diluted to 1.0, 0.5, 0.25, 0.1, and 0.05% relative to the test solution concentration for determining impurities. The resulting solutions were chromatographed.

Witryna1 lut 2015 · In the effective mass approximation, the Hamiltonian of a hydrogenic donor impurity located at the position r 0 in a quantum dot is given by H = H 0 − e 2 ε r − r 0 , where e and ε are the electron charge and medium permittivity, respectively. The Hamiltonian without impurity can be written as ⁎ H 0 = − ℏ 2 2 m ⁎ ∇ 2 + V ( x, y, z).
