Fig. 2: Structural characterization of wood xerogels.
From: Wood xerogel for fabrication of high-performance transparent wood
a FE-SEM micrographs of the D-wood and TO-wood xerogels, showing the cellular structure, cell corner, secondary cell wall, and cell wall surface, respectively. b Nitrogen adsorption-desorption isotherms of the TO-wood xerogel and the corresponding D-wood xerogel. c Pore size distribution derived from the N2 adsorption isotherm using a method based on the non-local density functional theory.
