This is a collection of papers on Fragmentation Phenomena. It includes reviews and reports on the latest developments in fragmentation of soft matter and materials (polymers, colloids, cells, droplets and rocks), fragmentation of microscopic objects (atomic clusters and nuclei), general topics and theoretical approaches. The book addresses students and young scientists as well as researchers in theoretical and experimental aspects of fragmentation phenomena.
