Figure 1From: Pathway control in the self-construction of complex precipitation forms in a Cu(II)-oxalate systemComplex precipitation structures: a Fingers with a precipitation disc, concentration of oxalate 0.05 M. On the left upper corner the pellet is visible (20 min after beginning of experiments). B Top view of a precipitation disk (CuC2O4 ) with crystals on top, oxalate concentration 0.11 M 24 h. C Side view of this structure. The formation of the disk occurs in 20 min. The disk diameter is about 3.0 cm. The picture was taken after 24 h.Back to article page
