The region between linear part of cathodic and anodic branch of polarization curves becomes wider when Tilia cordata extract is added to the acid solution [33, 34].
For C-, M-, S-, E-type astheoids, the characteristics of the negative branch of polarization curves turned out to correlate closely with the phase coefficient of the photometric function of asteroids and the photometric roughness of asteroid surfaces.
For a broad range of wavelengths angular dependence of linear polarization demonstrates (i) negative branch of polarization for phase angles ≤20° with the minimum Pmin ≈ 2%; ii) bell-shaped positive branch with low maximum of value Pmax ∼ 15 25% at the phase angle in the range 90-100°.
The anodic branches of the polarization curves for all treated Ti 6Al 4V samples demonstrate also that the oxide films break down at approximately 1.6 V, forming an active region.
The position and width of the transition region between the low- and high-current branches of the polarization curve are calculated.
The circumnucleus halo produces a noticeable negative polarization with an amplitude of 6 7%; whereas, the branch of negative polarization extends up to a phase angle α ≈ 30±.
A plateau of anodic Zn dissolution was discovered in the cathodic branch of the polarization curve, hidden by the large cathodic current.
The evolution of the mycelium is driven by key processes such as the uptake and transport of nutrients, branching and polarization of the hyphae.
As expected, wild-type trichomes were highly birefringent, indicated by transmission of light when a trichome branch was oriented appropriately relative to the plane of polarization, whereas cpr5-1 trichomeshoweded little detectable birefringence, and cpr5-2 trichomexhibitedted reduced birefringence.
For crystals greater than the absorption depth (65 µm for Si) the separate absorption coefficients should be considered; these are associated with the two branches of the dispersion surface and their two polarization states, leading to different values.
