Beyond species means – the intraspecific contribution to global wood density variation
New Phytologist, EarlyView.Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Co‐Impregnated MgAl Layered Double Hydroxide as an Efficient Catalyst for Glycerol Oligomerization
Applied Organometallic Chemistry, Volume 40, Issue 1, January 2026.A cobalt(II) acetylacetonate–impregnated MgAl LDH catalyst was developed, showing enhanced basicity and superior activity in glycerol oligomerization, achieving 68% conversion and 27% diglycerol selectivity. The catalyst maintained high performance over three recycling cycles, with structural and surface modifications confirmed by comprehensive ...
