Meanwhile, the significant reductions in the levels of apoptosis of chondrocytes, studied in a H2O2-dose dependent manner (0-2 mM), were observed with a use of a flow cytometer when the chondrocytes were cultured on the PCL/PHBV/50%NaCl scaffold in which more GAG content was found.

Magnetic study reveals reduction of the saturation magnetization (Ms) for Fe3O4@ZnS nanocomposites compared with uncoated Fe3O4 nanoparticles.
As seen in Figure 1(a), all diffraction peaks at 2θ=18.3°, 30.1°, 35.4°, 37.0°, 43.0°, 53.4°, 56.9°, 62.5°, 70.9°, 73.9° and 78.9° of the sample, can be assigned to a pure fcc (face-centered cubic) phase [space group: Fd3m (227)] of Fe3O4 with cell constants a = 8.396 Ǻ, which agree well with the reported diffraction pattern (data from JCPDS file No. 19-0629).
In Fig. 1(b), besides the corresponding peaks of magnetite, the diffraction peaks observed at 2θ= 28.6°, 47.5° and 56.3° were well indexed as (111), (220) and (311) planes of the known fcc phase ZnS (data from JCPDS file No. 05-0566), respectively.

These data are also processed to calculate or identify input parameters for the numerical investigations.
By simple uniaxial compression tests, measurement of axial and radial stresses and by numerical identification of input parameters the necessary data for Drucker-Prager-Cap material model in ABAQUS can be gained.
Fig. 4: Compressibility in layer compression test for disks compressed with different compression stresses made of chips Having a closer look on the tested specimens it can be seen that the reduction in height for the disks compressed with lower stresses in the chips pressing process is higher than for those being produced with 200 N/mm² or 300 N/mm², respectively.
An experimental setup for chip pressing that allows compressing the chips with different loads as to record important process data during the experiments was presented.

Material-technological models based on data obtained directly from a real press-hardening process were examined on two experimental steels, CMnSi TRIP and 42SiCr.
The data for developing the model was measured in a real-world process, with the tool either at room temperature or pre-heated to various temperatures.
Yet another reduction in the cooling rate to 10°C/s led to an increased proportion of ferrite, to even lower mechanical properties, and to no increase in elongation (Fig. 7).
Sequence 42SiCr-05 – press-hardening with Q&P processing – 10°C/s – 200°C – 250°C/600 s, martensite with ferrite and a small amount of bainite, SEM Summary In this experiment, a press-hardening route was tested which had been designed on the basis of data from a real-world forming process.

From the measured
data also a concentration - depth profile has been deduced.
(1) The information depth ξ is the average depth for a given specimen of thickness t from which the diffracted X-rays emerge weighed with an absorption factor accounting for the intensity reduction due to absorption: ( ) 00 exp exp 1 exp exp t t z t z dz t t z t z dz τ τ ξ τ τ τ − − = = = − − − − ∫ ∫
In this approach it is possible to determine effective XEC's according to ( ) V R 1,2 1,2 1,21 hkl S wS w S = + − , (8) by applying a least squares fit to the data in the f(ψ) plot with the stress and w as fit parameters [3].
The best fit obtained for the measured data points according to the f(ψ) method is achieved for w = 0.0753.
