The cover is an abstract illustration of the photocatalytic experiments carried out with methylene blue (MB). It should be observed turning the book 90 ± with the front cover on top. The front cover shows the color (concentration) gradient of MB when discolored by the radicals (sparkles) generated by the photocatalytic membrane (the spine), and the back cover shows the permeate. This cover also depicts how it is to work with a dye. Most of the surfaces where I worked will remain blue forever.
