Resistance of birch wood modified with sorbitol-citric acid to white-rot decay and weathering

Abstract The increasing interest in sustainable and bio-based wood modification strategies has led to growing attention toward improving the performance of low-durability wood species for exterior applications. Sorbitol-citric acid (SorCA) modification has previously been reporte...

The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites

Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...
