Wood and fibre properties of fertilized Norway spruce [PDF]

open access: yes, 2003
Very intensive forest management is relatively unexplored in Sweden, and while there is interest in pursuing e.g. the use of fertilizers on selected areas, there is concern about the quality of the wood when growth rate increases.

Nanolignin Functional Separators for Flexible Lithium–Sulfur Batteries With Enhanced Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Nanolignin‐functionalized separators, incorporating lignin nanoparticles into a crosslinked PEGDA coating applied on commercial separators, reduce polysulfide shuttling, thereby enhancing cycling performance in flexible lithium–sulfur pouch cells, while also improving thermo‐oxidative stability and flame retardancy.
