the largest technical university in Poland from 5 th -9 th September 2005. The E-MRS 2005 Fall Meeting consisted of 9 symposia and 6 satellite events and attracted about 500 participants. The Symposium H entitled "Filler metals, solders and joints of the next generation" was accompanied by industrial exposition and brought together about forty participants from all over the world to share new developments and experience in the field of material's joints. This emerging research field is driven by new requirements on structural components. Due to their complexity these requirements can not entirely be fulfilled by a single material and different materials (metal and ceramics, advanced composites with conventional materials) have to be combined to form a joint. However, often extreme differences in physical and thermal properties of joined materials, the environmental (lead prohibition in electronics) and geometrical issues (miniaturization trend) are confronting the scientific community and engineers with many challenges when developing and manufacturing reliable joints. The role of internal and external interfaces, the correlation between the joint design, processing parameters and joint properties, the size effects have to be understood; methods of control residual stresses have to be worked out to meet the goals. Oral and poster sessions of the symposium covered the aspects of development, modelling, processing and characterization of material's joints. Two invited lectures were presented: Dr Manfred Boretius delivered a lecture on state of the art and developments of vacuum brazing from the industrial perspective, while Prof. Heinrich Kern presented innovative work on composites with near-zero thermal expansion. In his plenary talk Prof. Phillipe Dubois focused on the design and properties of a perspective class of materials: clay/carbon nanotube polymer nanocomposites. The symposium papers of this present AEM issue exemplify recent research and reflect the state of the art in the field of material joining. Different kinds of joints are treated; they reach from lead-free solder joints, joints of dissimilar materials (e.g. metal-ceramic joints, composite materials and their joints) to joints of nanomaterials and nano-structures.
