Summary: A series of beta-disubstituted meso-tetraphenylporphyrins and their metal complexes were synthesized and characterized. The phenylethynyl-substituted porphyrin exhibited a remarkable red shift in absorption compared to the methyl- and phenyl-disubstituted porphyrins, due to the inductive and resonance effect of the substituent groups. Single-crystal X-ray structure analysis revealed different conformations of the porphyrin core for methyl-substituted and phenylethynyl-substituted porphyrins.

Summary: High cooling rate increases the concentration of solute atoms in the solidification structure, leading to a supersaturated solid solution. Al-Zn-Mg-Cu alloys with different Zr mass fractions were rapidly solidified. The microstructure and tensile properties of the alloys showed that the addition of Zr did not refine the grain size significantly, but improved their mechanical properties. Solution strengthening was the main mechanism for the improvement of mechanical properties in the as-cast alloys, while precipitation of L12-Al3Zr played a crucial role in the aged alloys, refining the size of theta MODIFIER LETTER PRIME-Al2Cu. Excessive Zr content caused the coarsening of L12-Al3Zr precipitations, deteriorating the mechanical properties.

Summary: In this work, the contrasting magnetic behavior of a bimorphic intermetallic compound TbPt3 is reported. The compound undergoes a structural phase transition and changes from a ferromagnetic state to an antiferromagnetic state. However, the antiferromagnetic state is unstable and can be induced to switch to a ferromagnetic state by applying a moderate magnetic field. Theoretical calculations suggest that the magnetic properties of the initial ferromagnetic state can be recovered by applying a magnetic field to the antiferromagnetic state. These findings provide an important opportunity to study the effect of crystal structure on the physical properties of TbPt3.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
