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

Electron-impact excitation of diatomic hydride cations I: HeH$^+$, CH$^+$, ArH$^+$ [PDF]
{\bf R}-matrix calculations combined with the adiabatic nuclei approximation are used to compute electron-impact rotiational excitation rates for three closed-shell diatomic cations, HeH$^+$, CH$^+$, ArH$^+$.

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

Effect of 2-Substitution on the Rearrangement of 1-Cyclopropylvinyl Cations [PDF]
2-Substitution in 1-cyclopropylvinyl cations produces a steric effect on cation generation and solvent trapping, but an electronic charge-stabilizing effect on cyclopropyl-to-cyclobutyl ...

Variation in Feedstock Wood Chemistry Strongly Influences Biochar Liming Potential
Chars intended for use as soil amendment (“biochars„) vary greatly in their chemical and physical properties. In the present study, 19 Canadian temperate wood feedstocks were charred across a range of pyrolysis temperatures from 300–700
