(a) Profiles of the mechanical collection efficiency according to the number of filter sheets overlapped with each other (Vi & Vf = 0). (b) Bar graph comparing the average collection efficiencies according to the number of sheets at various values of Vf. (c) Plot of the quality factor as a function of Vf for different number of sheets. (d) SEM images presenting the front and back surfaces of each ALCF filter after a filtration experiment involving four stacked filters. Each inset photograph shows the corresponding surface of the ALCF filter. The scale bars are 50 μm.
