Web29 dec. 2024 · Ursolic acid and Solasodine had two hydrogen bond donors and three hydrogen bond acceptors each. The topological polar surface area (TPSA) of ursolic acid was 57.53 Å 2. However, the lowest TPSA value was produced by solasodine at 41.49 Å 2. Ursolic acid exhibited the highest molar refractivity of 132.61. WebWithin the depletion approximation we suppose p n 0 in the depletion region. Another assumption is that all acceptors are ionized.

Web14 apr. 2024 · The dielectric constant ε r (or the static relative permittivity) describes the ability of a material to screen a charge, dampening the strength of its electric field. It is defined as the permittivity of a material divided by the permittivity of free space. The lower the dielectric constant, the less the material will screen an electric field. Webionized. There is no possibility of binding of elec-trons or holes to the polarization-induced charge, since it is dispersed over surfaces or volumes. This feature is of signiﬁcant beneﬁt in the nitrides, for which impurity acceptors have large binding ener-gies, and, consequently, relatively low ionization ratios at room temperature. 4.
