To assess the scaffold's behaviour under successive compressions the same sample specimens were repeatedly compressed at least three times and, in a case of Col(S), also after 10 days in water.
A 2D layered perovskite-type hybrid structure of the form [(CH3(CH2)19NH3)2(PbX4 ], X = Cl, and Br, in which, two-dimensional sheets stabilized by a inner bilayer of organic monoammonium cation matrix, is mechanically tailored by successive compression-expansion cycles.
A statistical analysis is conducted on sequential {1 0 −1 2}–{1 0 −1 2} double extension twinning in a Mg AZ31 alloy obtained after two mutually perpendicular successive compressions.
Accordingly, the calculated free energy per area of a liquid aggregate, when subjected to two successive compressions, the second (σ2) greater than the first (σ1), will remain constant.
Compression tests and then compression shearing at an angle of 45° were performed on the same samples to obtain successive compressions of 2, 3, and 6 mm.
Young's moduli calculated from the curves after successive compressions reveal, however, some differences in scaffold elastic properties, more evident for weakly EDC XL scaffolds.
It was shown that scaffold mechanics was highly dependent upon the EDC content for all compositions, and that in order to achieve stable resistance under successive compressions the 3D matrices should be treated with 10% EDC or more, especially in the case of Gel-derived samples.
This was achieved by successive continuous compression and decompression in a diamond anvil cell at temperatures under, at and above the critical point.
