Wood Nutrient-Water-Density Linkages Are Influenced by Both Species and Environment

open access: yesFrontiers in Plant Science, 2022
Tropical trees store a large amount of nutrients in their woody tissues, thus triggering the question of what the functional association of these elements with other wood traits is. Given the osmotic activity of mineral elements such as potassium, sodium,

Erionite-Na upon heating. Dehydration dynamics and exchangeable cations mobility [PDF]

open access: yes, 2016
Erionite is a fibrous zeolite significantly more tumorigenic than crocidolite asbestos upon inhalation. In recent years, several papers have been published aimed at characterizing from the crystal-chemical point of view erionite fibres. As their toxicity
