Sem Images Of Surface A Cross Section B Bottom Side C And The dense active layer of pa with a thickness of 50 70 nm on the porous pes is evident in figure 3 b. figure 3 c shows that all the pores at the bottom side of pes were open. view in full text. The bottom micrograph of the ps support layer has distinct porous structure with different pore diameter as shown in fig. 4(b). fig. 4(c) shows the cross section image of the tfc pa ro membrane.

Sem Images Of Surface A Cross Section B Bottom Side C And Fig. 9 shows the optical images of the grain structure on top surface, bottom surface, and side cross section of the sample printed with a hatch distance of 100 μm and point distance of 60 μm. Surface sem of the mf and uf membranes are processed via nih image j software to calculate the porosity and average pore diameters. the extracted gray scale image is converted into a black and white image where the white areas are solid polymer and the black areas are pores ( xiao et al., 2022 ; wu et al., 2022 ). This, therefore, results in the formation of larger diametrical cellular structures. this is particularly evident when one compares the cross section and support side surface sem images of the dual cast 20pvdf 10pvdf ccd membrane (fig. 3c and e) to that of single cast 20pvdf ccd membrane (fig. 2c and e). the former has a more porous support. The bottom image shows a cross sectional view of two stomata, indicated by arrows. the leaf axis is vertical in the center image and perpendicular to the page in the bottom image. figure 4: agave “blue glow” leaf surface that has been peeled from a leaf.
