Non-classical pathways during calcium oxalate precipitation in the presence of citrate. a Schematic drawing illustrating the sequence of stages during calcium oxalate formation in the presence of citrate. b An overview of the energetics of calcium oxalate crystallization pathways from supersaturated solutions under thermodynamic (classical pathway, black line) and kinetic control (this study, blue line in the absence of citrate and red line in the presence of citrate)
