“…The doped BZBO crystals showed improved SHG response. 22,23 The electrical and optical properties of the BZBO crystal as a type of crystal material with a noncentrosymmetric structure are worthy of a comprehensive study. However, the literature mostly focuses on the synthesis and optical properties of the crystal, studying on the electroelastic properties of this crystal is very limited.…”

A Bi2ZnB2O7 single crystal measuring 45 mm × 35 mm × 15 mm was grown by using the Kyropoulos method. The as-grown crystal showed distinct crystal facets (001), (010), and (110), among others, which were consistent with the ideal growth morphology predicted by the Bravais-Friedel and Donnay-Harker method. The electric, elastic, and piezoelectric properties of the Bi2ZnB2O7 single crystal were examined, using the impedance and pulse-echo methods for the first time. The independent piezoelectric coefficients d 15, d 24, d 31, d 32, and d 33 were evaluated and found to be of the value of 1.4, −5.5, 2.5, −6.4, and 1.1 pC/N, respectively. The contributions of the crystal symmetry space group to the piezoelectric property were analyzed from the viewpoint of polyhedral distortion and net dipole moment. The temperature-dependent behaviors of the electroelastic properties were characterized in the temperature range from room temperature to 500 °C. Within this temperature range, the highest electromechanical coupling factor k 32 (14.5%) and piezoelectric coefficient d 33 (1.1 pC/N) exhibited temperature-independent behavior.

“…The main goal of the paper is to provide an efficient, qualiative and quantitative evaluation method of assorted surface mechanical properties and topography of nanofibrous, biodegradable tissue engineering scaffolds with using an atomic force microscopy technique (AFM). AFM allows to examine topography and, due to the operating principle (physical contact between scanning probe and tested surface) it allows also acquisition of additional information describing materials surface [5][6][7] (Fig. 1), in particular: local changes of stiffness, adhesion or deformation, local changes of friction forces acting between scanning probe and material surface and moreover local changes in so called phase contrast.…”

Biodegradable polymeric fibers with nanoand submicron diameters, produced by electrospinning can be used as scaffolds in tissue engineering. It is necessary to characterize their mechanical properties especially at the nanoscale. The Force Spectroscopy is suitable atomic force microscopy mode, which allows to probe mechanical properties of the material, such as: reduced Young's modulus, deformation, adhesion, and dissipation. If combined with standard operating mode: contact or semicontact, it will also provide advanced topographical analysis. In this paper we are presenting results of Force Spectroscopy characterization of two kinds of electrospun fibers: polycaprolactone and polycaprolactone with hydroxyapatite addition. The average calculated from Johnson-Kendall-Roberts theory Young's modulus was 4 ± 1 MPa for pure polymer mesh and 20 ± 3 MPa for composite mesh.
