Production of Activated Carbon From Grape Stems After Tannin Extraction: An Integrated Valorization Approach

CLEAN – Soil, Air, Water, Volume 53, Issue 12, December 2025.
Grape stems offer dual valorization potential: as a tannin source for coagulant synthesis and as a precursor for activated carbon production. The process utilizes the residual biomass after tannin extraction, and adsorption tests demonstrate that this adsorbent is competitive with others reported in the literature.

Comparison of support vector machine, random forest and neural network classifiers for tree species classification on airborne hyperspectral APEX images

European Journal of Remote Sensing, 2017
Knowledge of tree species composition in a forest is an important topic in forest management. Accurate tree species maps allow for much more detailed and in-depth analysis of biophysical forest variables.

Dual Isotope Analysis Reveals Phylogenetic Patterns and Novel Insights Into Methoxy Group Synthesis of Structural Biomolecules in Leaf and Woody Plant Tissues

Plant, Cell &Environment, Volume 48, Issue 12, Page 8483-8501, December 2025.
ABSTRACT Stable carbon and hydrogen isotopes of wood methoxy groups (δ2Hmeth, δ13Cmeth), mainly sourced by structural biomolecules like lignin and pectin, provide important insights into climatic, hydrological and physiological conditions. This study systematically investigated species‐specific δ2Hmeth and δ13Cmeth variations in leaves and woody twigs ...

Bois pourri et santé des forêts : exemple du mélange épicéa (Picea abies [L.] Karst.) et mélèze (Larix decidua Mill.) en forêt subalpine de Sainte-Foy-Tarentaise (Savoie)

Revue Forestière Française
La coexistence du mélèze et de l’épicéa est interrogée à la lumière des multiples pressions que subissent les forêts subalpines. L’hypothèse énoncée par cette étude est que l’impact de la durée d’ensoleillement, de la végétationconcurrente et de la forme

Consequences of different sample drying temperatures for accuracy of biomass inventories in forest ecosystems

Scientific Reports, 2020
Biomass estimation is one of the crucial tasks of forest ecology. Drying tree material is a crucial stage of preparing biomass estimation tools. However, at this step researchers use different drying temperatures, but we do not know how this influences ...
