An improved theory for calculating leaf gas exchange more precisely accounting for small fluxes
gas exchange leaf von Caemmerer and Farquhar (vCF)
2023/12/8
The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for...
Advanced nanocellulose-based gas barrier materials: Present status and prospects
Nanocellulose Gas barrier Layer-by-layer materials Composites Biomaterials
2023/12/7
Nanocellulose based gas barrier materials have become an increasingly important subject, since it is a widespread environmentally friendly natural polymer. Previous studies have shown that super-high ...
Xylem embolism spread is largely prevented by interconduit pit membranes until the majority of conduits are gas-filled
drought optical vulnerability pit membranes water relations xylem transport
