Glass-ceramic scaffolds for bone grafting have been prepared using the sponge replication method and a highly bioactive silica based glass belonging to the system SiO2-P2O5- CaO-MgO-Na2O-K2O (CEL2). The parameters for the sponge impregnation were optimized in order to obtain a continuous coating of the polymeric skeleton which will lead, after the polymeric phase removal, to a resistant macroporous glass-ceramic template. A complete characterization was carried out on the obtained scaffold in order to assess its morphology and specifically its porosity and the degree of pores interconnection. A human osteoblasts cells line (MG-63) was cultured onto the scaffold and the effect of stimulation with shock waves on the cell ability of colonizing the scaffold was investigated.

We show that atomic gasses can support solitary pulses of unipolar, non-oscillating EM-field ("EM-bubbles") of up to the atomic amplitude, with their length ranging from ~10−9 s to ~10−16 s , which propagate without dispersion and are stable and insensitive to the change of gas density. We found the condition on the atomic potential necessary for formation of EM-bubble. Atomic gasses can also support an EM shock which is a precursor of a cw ionizing field.
