1.A (upper left): Control sample, was not treated with AESUB-spray. 1.B (upper right): Sample treated with AESUB Blue. 1.C (lower left): Sample treated with AESUB Transparent. 1.D (lower right): Sample treated with AESUB Yellow.
All samples were partially covered by aluminum foil. 1.B-1.D were treated with approx. 84 layers of AESUB-spray. One layer is defined as one horizontal and one vertical zig-zag movement with up to 5 strokes in each direction. A clear visual divide can be seen between the treated areas (left sides) and the untreated areas (right sides) on the treated samples.
The images were adjusted for the purposes of this abstract, by translating the text from Danish to English. Credit:
