“…Imidazole‐dicarboxylic acid is known for its metal chelating properties and can form metal‐organic frameworks that could be useful in a variety of applications such as catalysis (Zhang et al ), functional materials (Feng et al ), and chemical sensors (Li et al ). In this study, the complex formed between 2‐ethyl‐4,5‐imidazole‐dicarboxylic acid and the nickel ion was high yielding, crystalline, and stable.…”

In the pearl cultivation industry, the implantation of the nucleus is a critical step in the production process. The surgical insertion of the nucleus and the mantle results in a wound and stress that affect not only the survival chances of the pearl oysters but also the quality of the pearls produced. This study proposes a synthesized imidazole-dicarboxylic acid nickel complex that may hold potential in assisting the wound healing and nacre formation processes. The acute toxicity of the complex to pearl oysters, Pinctada martensii, was examined in a dose-response study over a 90-h exposure. The safe concentrations of the nickel complex determined using probit analysis were 0.916 mg/L and 0.471 mg/L for 72-h and 96-h treatments, respectively. The reliability of the regression was verified using the chi-square test. The alkaline phosphatase (ALP) activity in different regions of the treated and control oysters, along with relevant blood biochemical indices, were measured over a 90-d period to predict the potential effects of the nickel complex on wound healing and nacre formation. A significant increase in ALP activity in the mantle, together with elevated blood levels of Mg (II) and globulin, and reduced blood levels of Zn (II) and blood urea nitrogen were observed. These results indicate that the prepared nickel complex may hold promise in helping wound healing post mantle implantation, promote the secretion of nacre, and enhance the immunity of the oysters, thus ultimately improving the yield and quality of the pearls.

“…In view of the above, it is critically important to determine the structure of molecular compounds that are used as catalysts, especially if such compounds have bidentate ligands that could render these compounds polymeric, in order to establish how such compounds act as catalysts [ 17 , 18 ]. There are only limited reports in the literature on the use of supported catalysts in the hydrogenation process and comparing their catalytic activity and selectivity to their homogeneous counterparts, either computationally (in silico) or by experimental methods, is therefore highly relevant for progress in this field.…”

The Transfer Hydrogenation of Cinnamaldehyde Using Homogeneous Cobalt(II) and Nickel(II) (E)-1-(Pyridin-2-yl)-N-(3-(triethoxysilyl)propyl)methanimine and the Complexes Anchored on Fe3O4 Support as Pre-Catalysts: An Experimental and In Silico Approach

The imino pyridine Schiff base cobalt(II) and nickel(II) complexes (C1 and C2) and their functionalised γ-Fe3O4 counterparts (Fe3O4@C1 and Fe3O4@C2) were synthesised and characterised using IR, elemental analysis, and ESI-MS for C1 and C2, and single crystal X-ray diffraction for C1, while the functionalised materials Fe3O4@C1 and Fe3O4@C2 were characterized using IR, XRD, SEM, TEM, EDS, ICP-OES, XPS and TGA. Complexes C1, C2 and the functionalised materials Fe3O4@C1 and Fe3O4@C2 were tested as catalysts for the selective transfer hydrogenation of cinnamaldehyde and all four pre-catalysts showed excellent catalytic activity. Complexes C1 and C2 acted as homogeneous catalysts with high selectivity towards the formation of hydrocinnamaldehyde (88.7% and 92.6%, respectively) while Fe3O4@C1 and Fe3O4@C2 acted as heterogeneous catalysts with high selectivity towards cinnamyl alcohol (89.7% and 87.7%, respectively). Through in silico studies of the adsorption energies, we were able to account for the different products formed using the homogeneous and the heterogeneous catalysts which we attribute to the preferred interaction of the C=C moiety in the substrate with the Ni centre in C2 (−0.79 eV) rather than the C=O (−0.58 eV).

“…Metal-organic frameworks (MOFs) are fascinating porous coordination polymers (CPs), which are made up of organic ligands and metallic cations or metal-containing nodes [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. Owing to their high intermolecular pores, specific surface area, unsaturated active metal sites, and structural and functional diversities [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ], they have adopted a critical interest in various fields, such as energy storage, ion exchange, sensors, drug delivery/release, separation, molecular recognition, catalysis and theranostics [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 ].…”

With the continuous evolution of bacteria and the constant use of traditional antibiotics, the emergence of drug-resistant bacteria and super viruses has attracted worldwide attention. Antimicrobial therapy has become the most popular and important research field at present. Coordination Polymer (CP) and/or metal-organic framework (MOF) platforms have the advantages of a high biocompatibility, biodegradability, and non-toxicity, have a great antibacterial potential and have been widely used in antibacterial treatment. This paper reviewed the mechanism and antibacterial effect of three typical MOFs (pure Ag-MOFs, hybrid Ag-MOFs, and Ag-containing-polymer @MOFs) in silver-based coordination polymers. At the same time, the existing shortcomings and future views are briefly discussed. The study on the antibacterial efficacy and mechanism of Ag-MOFs can provide a better basis for its clinical application and, meanwhile, open up a novel strategy for the preparation of more advanced Ag-contained materials with antibacterial characteristics.
