It is a big challenge to retain the water and thus reduce the charge impedance for solid electrolytes used in flexible and wearable zinc ion batteries. Here, we propose novel phytic acid (PA) cross-linked polyvinyl alcohol (PVA) hydrogels as high-performanced solid electrolytes strengthened by the Hofmeister effect. In this approach, freeze-thawing followed by a salting-out procedure anions to induce the Hofmeister effect can greatly improve the tensile strain and flexibility of the hydrogels. The PA addition dramatically enhances the ionic conductivity and increases the affinity between the electrolyte and zinc plate. Consequently, the PVA/PA hydrogels exhibit remarkable electrochemical performances with stable full-cell cycling in zinc ion storage and capability in inhibiting Zn dendrite growth.

Male infertility is a common complication of diabetes. Diabetes leads to the decrease of zinc (Zn) content, which is a necessary trace element to maintain the normal structure and function of reproductive organs and spermatogenesis. The purpose of this study was to investigate the effect of metformin combined with zinc on testis and sperm in diabetic mice.

The regulation of artificial interphase for advanced Zn anode is an effective solution to achieve superior electrochemical performance for aqueous batteries. However, the deployment of atomically precise architectures and ligand engineering to achieve functionalization-oriented regulatory screening is lacking, which is hindered by higher requirements for synthetic chemistry and structural chemistry. Herein, we have first performed ligand engineering which selected zinc ion trapping ligands (-CH3) based on the coordination effect, and zinc substrate binding ligands (-N=N-xC6H5) based on the electrostatic interaction.

Although significant progress has been made in the effective measurement of Zn(II), Аlizarin red S (ARS) was immobilized on polyethylene polyamine-modified polyacrylonitrile (PPF-1) via a new matrix. This approach allows the detection of low levels of Zn(II) ions in various water samples via preconcentrated atomic absorption spectrometry. The use of PPF-1 in a polymer matrix for zinc preconcentration presents several advantages over traditional sorbtion-spectroscopic methods, including reduced cost, high zinc recovery, increased sensitivity, and selectivity.

Objective: To develop a rapid, convenient, accurate, and low-residual-effect ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the determination of polymyxin B sulfate and colistin sulfate in the blood of patients with multidrug-resistant bacterial infections, as well as caspofungin acetate in the blood of patients with fungal infections, thus facilitating the rational use of antibiotics in clinical applications.
Methods: All analytes were diluted with 0.2 % aqueous formic acid, and plasma proteins were precipitated using acetonitrile.
