Saturation of Spin-Polarized Current in Nanometer Scale Aluminum Grains [PDF]
Physical Review B, 2007 We describe measurements of spin-polarized tunnelling via discrete energy levels of single Aluminum grains. In high resistance samples ($\sim G\Omega$), the spin-polarized tunnelling current rapidly saturates as a function of the bias voltage.

Aluminum dynamics in nitrogen‐saturated Andisols in Tokyo
Ecological Research, 2023 Abstract The debate over whether forests around the Tokyo metropolitan area are nitrogen (N) saturation persists, as atmospheric N deposition in throughfall has decreased. This decrease is evidenced by a notable decline in samples collected in the 1990s (especially 1991–1992 and 1995).

The Response of Soil pH and Exchangeable Al to Alum and Lime Amendments
Agriculture, 2021 Intensive cultivation and unprecedented utilization of ammoniacal fertilizer has accelerated soil acidification in the southern Great Plains and many other parts of the world. During a two-year study that evaluated the impact of soil pH and aluminum (Al)

Woody species distribution across a savanna-dry forest soil gradient in the Brazilian Cerrado
Brazilian Journal of Biology, 2021 Although richness and distribution of woody species in the Cerrado physiognomies have been extensively studied, the shifts of woody species from savanna physiognomies to dry forests have not yet been addressed.
