ABSTRACT
The microstructure and mechanical properties of extruded AZ31 + xTiCN (x = 0, 0.4, 0.8, 1.2 wt%) were investigated, and the strengthening mechanism was discussed. X-ray diffraction and energy dispersive spectroscopy (EDS) confirmed that the Al4C3 and Al2MgC2 duplex phase particles were generated in situ by TiCN and Al particles, which act as the nucleation precursors of Mg grains during solidification. The grain size decreased and then increased with increasing TiCN addition. The yield strength (YS) and ultimate tensile strength (UTS) increased with increasing TiCN addition reaching a maximum (217.5 MPa) at 0.4 wt%, and in contrast, the elongation index (EI) continuously decreased with increasing TiCN addition.
ABSTRACT
Three new complexes derived from 2-(4-(pyridin-2-yl)piperazin-1-yl)acetic acid (HL), [M(L)2(H2O)2] where M = CuII (1), ZnII (2) and CdII (3), have been synthesized and characterized by IR spectroscopy, elemental analysis and X-ray crystallography. The inhibitory activity of these three complexes against MAO-B was tested in vitro, and the molecular docking experiments were also carried out to rationalize their binding models. Both the experimental and docking simulation results indicated that complex 1 has the best inhibitory activity with IC50 value being 6.5 ± 0.31 µM.
