Fig. 4

A three-dimensional (3-D) renderings of the synchrotron-based-XTM images of rice straw (a) and rice straw-derived biochar (b) representing the pore types including the open-pore and closed-pore. Volume rendering of the pore architecture in a representative straw/biochar fragment (scale bar = 500 μm). Higher-magnification orthoslice from the same dataset illustrating pore types, including open pores and closed pores (scale bar = 100 μm).
