AbstractPulsed Laser Deposition (PLD) was used to deposit La-doped Pb(Zr,Ti)O3 (PZT) thin films onto NiTi foils. The substrate alloy with composition Ni50Ti50 shows a strong shape memory effect with a transition temperature of about 80°C. This simple bicomponental system could have the potential of an actuator device (NiTi shows a strain up to 5 % during thermal cycling) with an inherent sensorial component (PZT) for the generated elongation. The deposited ceramic films were characterized with respect to their structural properties (XRD) and their ferroelectric behavior (P-E hysteresis). Under certain deposition conditions the growth of pure perovskite PZT on the polycrystalline shape memory alloy was observed. The growth morphology of PZT on NiTi was compared to the one of PZT on single crystalline substrates whereas no distinctive texture of the films on NiTi could be found. The ferroelectric behavior of the PZT films depend on the stage of bending of the film-substrate compound.

Full Correction

Results of operative treatment using radical thoracoplasty in 31 patients with funnel breast were analyzed. Mean age of patients was 14.98±4.36 years. All patients had concomitant spine deformity. For purpose of cosmetic effect improvement the mini-invasive submammary accesses were used. Fixatives of sternocostal complex from nickel-titanium with shape-memory were worked out. The shape memory effect was achieved by cooling of the implant that resulted in implant plasticity. After being inserted the implant restored its original shape. That technique allowed achieving full correction of the deformity and positive cosmetic effect in all patients. No complications associated with plate migration were revealed. Radical thoracoplasty with thoracocostal complex stabilization by plate with shape-memory effect is pathogenetically justified and allows correcting the funnel chest of any degree and form and is indicated to patients of any age groups.
