Zinc and vitamin C are essential micronutrients for the conservation of the human body, being essential for the maintenance of the immune system, reducing the risk, severity and duration of infectious diseases. They are taken together as a food supplement, resulting in the improvement of pneumonia and malaria infections. Vitamin C and zinc are also associated with measures of obesity and adiposity. Studies report that vitamin C complexed in zinc promotes adipogenesis and stimulates the generation of insulin-responsive adipocytes. Therefore, since vitamin C together with zinc are fundamental for the body, and that vitamin C complexed with zinc can promote adipogenesis and stimulate the generation of adipocytes responsive to insulin, the study of the interaction between these micronutrients will broaden the understanding of its bioactivity, which may be important in the study of a new use of vitamin C and zinc combined. Thus, it is intended to study the complexation of Vitamin C with the zinc ion using simulations of Molecular Dynamics ab initio. Through the results of the dynamics, it is found that zinc interacted significantly with 3 atoms of vitamin C, thus identifying the formation of a tridentate complex, since the average distances between the metal and these atoms were between 2.176 and 2.261 Å. A decrease in the free Helmholtz energy is perceived as the zinc approaches these atoms, up to a distance of high stability, which corresponds to the average distance of these interactions. It is also evident that the complexation energy is -220,64 Kcal/mol indicating that the complexation is energetically favorable and that the complex formed is stable. Therefore, the results obtained broadened the knowledge about the complexation of zinc ions with vitamin C, which will be of great importance for the understanding of its bioactivity and in the planning of new drugs.

The compressive fracture and spalling of multiply-cracked brittle coating layer on metal substrate under tensile stress was studied for the anodic-oxidized aluminum wire with the Al2O3 coating layer and galvannealed IF steel plate with the intermetallic compound coating layer consisting of ζ, δ1 and Γ1 and Γ phases. The thin Al2O3 coating layer on Al wire was fractured by buckling in the circumferential direction by the compressive hoop stress, but thick layer was debonded by the tensile radial stress at interface. The thickness of the coating layer at the transition from the compressive fracture to interfacial debonding was around 30 µm. In the galvannealed steel plate sample, the (ζ+δ1) phases were fractured by buckling in the width direction, resulting spalling of the (ζ+δ1) phases in the first stage, and the remained (δ1+Γ1+ Γ) phases or (Γ1+Γ) phase was again fractured by buckling, followed by the spalling of the remained phase.

AbstractThe rapid advance of mild aqueous zinc-ion batteries (ZIBs) is driving the development of the energy storage system market. But the thorny issues of Zn anodes, mainly including dendrite growth, hydrogen evolution, and corrosion, severely reduce the performance of ZIBs. To commercialize ZIBs, researchers must overcome formidable challenges. Research about mild aqueous ZIBs is still developing. Various technical and scientific obstacles to designing Zn anodes with high stripping efficiency and long cycling life have not been resolved. Moreover, the performance of Zn anodes is a complex scientific issue determined by various parameters, most of which are often ignored, failing to achieve the maximum performance of the cell. This review proposes a comprehensive overview of existing Zn anode issues and the corresponding strategies, frontiers, and development trends to deeply comprehend the essence and inner connection of degradation mechanism and performance. First, the formation mechanism of dendrite growth, hydrogen evolution, corrosion, and their influence on the anode are analyzed. Furthermore, various strategies for constructing stable Zn anodes are summarized and discussed in detail from multiple perspectives. These strategies are mainly divided into interface modification, structural anode, alloying anode, intercalation anode, liquid electrolyte, non-liquid electrolyte, separator design, and other strategies. Finally, research directions and prospects are put forward for Zn anodes. This contribution highlights the latest developments and provides new insights into the advanced Zn anode for future research.
