Zinc Hexacyanoferrate

Zinc-ion batteries (ZIBs) have received attention as one type of multivalent-ion batteries due to their potential applications in large-scale energy storage systems. Here we report a prototype of rocking-chair ZIB system employing Zn2Mo6S8 (zinc Chevrel phase) as an anode operating at 0.35 V, and K0.02(H2O)0.22Zn2.94[Fe(CN)6]2 (rhombohedral zinc Prussian-blue analogue) as a cathode operating at 1.75 V (vs. Zn/Zn2+) in ZnSO4 aqueous electrolyte. This type of cell has a benefit due to its intrinsic zinc-dendrite-free nature. The cell is designed to be positive-limited with a capacity of 62.3 mAh g−1. The full-cell shows a reversible cycle with an average discharge cell voltage of ~1.40 V, demonstrating a successful rocking-chair zinc-ion battery system.

The aqueous rechargeable zinc ion battery (ARZIB) system has been actively studied in the field of energy storage. Prussian blue analogues (PBAs) are considered effective cathode materials in the ARZIB system. In our previous study, Zn(NO3)2 solutions of different concentrations were used as electrolytes in an ARZIB system with a zinc hexacyanoferrate (ZnHCF) electrode. And the effect of electrolyte concentration on the electrochemical performance was studied. In this study, the effect of electrolyte concentration was demonstrated through electrochemical tests and Raman analysis. Charge/discharge tests were conducted at different electrolyte concentrations. And electrochemical performance degradation was observed above a certain electrolyte concentration. This effect was due to the strong interaction between the zinc cations and the nitrate anions, confirmed by the Raman spectroscopy analysis of the Zn(NO3)2 electrolyte.

Mmp Genes

Матриксные металлопротеиназы (ММП) - ферменты класса гидролаз, осуществляющие ферментативный катализ с помощью связанного в активном центре иона цинка. Функции ММП разнообразны, и нарушение баланса их активности может быть одним из этиологических факторов различных заболеваний. В данном обзоре рассмотрена классификация ММП человека, особенности их структуры и регуляции, а также роль в физиологических и патологических процессах в организме человека. Приведен перечень наиболее изученных на настоящий момент полиморфных вариантов генов MMП, описаны их функциональные эффекты и представлены результаты ассоциативных исследований. Matrix metalloproteinases (MMPs) are enzymes of the hydrolase class that carry out enzymatic catalysis with the help of a zinc ion bound in the active center. MMP functions are diverse, and a disturbance in the balance of their activity may be one of the etiological factors of various diseases. In this review, the classification of human MMP, the features of their structure and regulation, as well as the role in physiological and pathological processes in the human body are considered. A list of the most studied polymorphic versions of MMP genes has been given, their functional effects have been described, and the results of associative studies have been presented.
