Comparative decay resistance of plantation-grown and naturally-grown teak wood (Tectona grandis L.f.)

BOIS & FORETS DES TROPIQUES, 2023
Teak (Tectona grandis L.f.) is one of the most popular tropical timber species for its natural durability. The sapwood, the outer, middle, and inner heartwood, and the pith of plantation-grown teak in Indonesia and naturally grown teak in Myanmar were tested for decay resistance (a major component of natural durability), applying an accelerated decay ...

Natural resistance of four Amazon woods submitted to xylophagous fungal infection under laboratory conditions

Madera y Bosques, 2017
The present study aimed to assess the natural resistance of four Amazon tropical wood species, used in the production of sawn timber, against infection with xylophagous fungi. Apuleia leiocarpa (amarelão), Dinizia excelsa (angelim vermelho), Vochysia maxima (quaruba), and Bagassa guianensis (tatajuba) were selected to perform the accelerated laboratory

Unveiling the Role of Curvature in Carbon for Improved Energy Release of Ammonium Perchlorate

Advanced Materials, EarlyView.
High‐curvature carbon materials identified via machine learning and simulation can enhance the heat release and combustion performance of ammonium perchlorate. ABSTRACT The catalytic role of carbon curvature in the thermal decomposition of ammonium perchlorate (AP) remains largely unexplored. To address this gap, this study employs machine learning and
