“…Mononuclear cobalt complexes showing catecholase activity are relatively rare in the literature [64][65][66][67][68][69]. So, cobalt(III) complex 1 is one of the few examples of a mononuclear cobalt(III) complex having catecholase activity for which both the single crystal X-ray structure and k cat value have been determined.…”

“…[ 30,58 ] The tetra‐coordinate zinc complexes especially those with salicylaldimine ligands are usually tetrahedral (SP 3 hybridization), and the involvement of salicylaldimine ligands in coordination was reported to be via the imine nitrogen and the hydroxyl oxygen atoms in a monobasic manner. [ 59–61 ] The analytics only showed negligible differences between the nonsonicated and sonicated complex regarding the CHN composition, FT‐IR data and DMF solution electrical conductivity clearing the same formula of [ZnL 2 ] for the complex in both cases (Figure 1). The IR spectra of HL and [ZnL 2 ] (nonsonicated and sonicated) were studied.…”

The complex [ZnL2] {HL = 2‐(((3,4‐dimethylphenyl)imino)methyl)phenol} was introduced by two routes (chemical vs. sonochemical) and acted as a source of different size zinc‐oxide (ZnO) nanoparticles (NPs) (nonsonicated ZnO NPs of Brunauer–Emmett–Teller (BET) surface area of 19.208 m2 g−1, total pore volume of 0.03493 cc g−1, and particle diameter of 20.49–114.89 nm vs. sonicated ZnO NPs of BET surface area of 38.383 m2 g−1, total pore volume of 0.08723 cc g−1 and particle diameter of 15.09–55.31 nm). The NPs generate cell stress that leads to the formation of reactive oxygen species (ROS). Consequently, carotene biosynthesis can be enhanced to overcome the ROS. Rhodotorula toruloides MH023518, genetically identified with 18S rRNA, produced carotenoids (124 ± 4.5 mg L−1) and lipids (0.897 ± 0.01 mg L−1) under no NPs' stress, but these values increased to total carotenoids of 264 ± 0.6 and 297.78 ± 0.8 mg L−1 and total lipids of 0.97 ± 0.007 and 1.096 ± 0.015 mg L−1 under stress conditions of 50 ppm of the nonsonicated and sonicated ZnO NPs, respectively. These results may represent potential industrial utilization of the as‐formed ZnO NPs (particularly the sonicated sample) as carotene and lipid stimulator. Additionally in this article, the soluble proteins, total antioxidants, and catalase and superoxide dismutase specific activities of the yeast in the presence of various concentrations of the as‐formed ZnO NPs were determined.

A modern approach for the sensing of aqueous Al(III) ion by Ni(II) Salen‐type Schiff base complexes

In this work, we explore a modern concept of transmetalation (metal exchange) for the effective recognition of aqueous Al(III) ion. Three different Ni(II) salen‐type Schiff base complexes with different spacer diimine groups were prepared for the metal exchange reaction. These probes recognize Al(III) both colorimetically as well as fluorimetrically. The efficiency in sensing is mainly due to the low emission characteristics of the respective Ni(II) complexes which results in enhanced emission on the formation of Al(III) complex. The geometry of the central Ni(II) metal ion in the probe plays a pivotal role in the sensing action with the highest sensitivity being shown by the Ni(II) metal center with distorted square pyramidal geometry. Further DFT calculations and the energetics involved in the sensing mechanism via the formation of Al(III) complexes substantiates the experimental results.
