Cellular arrangement of matter is a building principle of the nature. The combination of material and structural properties results in a set of completely new properties of solids. Nowadays physicists, chemists, materials scientists and engineers explore those combinations by mimicing cellular structures of all material classes. Potential new applications have been identified in the fields of energy saving, light weight construction, novel and efficient conversion concepts or biomedical repair functions, just to mention a few. In order to bring together experts from polymer, ceramic, glass and metal communities dealing with cellular materials, the CELLMAT conference series was started in 2010. Current topics of the 2nd CELLMAT will cover all aspects of manufacturing, modification, joining, structural characterisation and property analysis. In a side event a strong focus will be set on applications of cellular materials. International experts will give plenary lectures about the applications in automotive and transportation, in mechanical engineering, for chemical and energy systems, for environmental purposes or for micro and medical devices and functions. The 3-days conference comes up as a discussion panel between researchers, manufacturers and users of cellular materials. During the conference, excellent results in applications of cellular materials will be honoured with the CELLMAT-Awards, and the best three posters will be selected. We cordially invite you to join the CELLMAT conference, to be held in the beautiful city of Dresden, and share your experience in cellular materials.
