- who: Ruxandra Cojocaru and colleagues from the (UNIVERSITY) have published the paper: A biological nanofoam: The wall of coniferous bisaccate pollen, in the Journal: (JOURNAL) of March/16,/2022
- what: The authors report the inner structure of the pollen wall in the cappa region (the thickened upper surface between the two air sacs) as a solid nanofoam. By comparing AFM results between both modern and fossil bisaccate pollen specimens, the authors show that the mechanical properties of the pollen wall are retained in fossils. This study has explored the structural and mechanical properties of the . . .
