Cooperativity in Chiroptical Sensing with Dendritic Zinc Porphyrins

Journal of the American Chemical Society, 2005
Zinc porphyrin-appended dendrimers, 12PZn, 18PZn, 24PZn, and 36PZn, containing 12, 18, 24, and 36 zinc porphyrin units, respectively, were synthesized using zinc porphyrin dyad (2PZn) and triad (3PZn) as precursors. Although these dye-functionalized dendrimers all serve as chiroptical sensors for an asymmetric bipyridine (RR- and SS-Py2), the sensing ...

Interfacial Design of Dendrite‐Free Zinc Anodes for Aqueous Zinc‐Ion Batteries

Angewandte Chemie, 2020
AbstractAqueous zinc‐ion batteries have rapidly developed recently as promising energy storage devices in large‐scale energy storage systems owing to their low cost and high safety. Research on suppressing zinc dendrite growth has meanwhile attracted widespread attention to improve the lifespan and reversibility of batteries. Herein, design methods for

Review of zinc dendrite formation in zinc bromine redox flow battery

Renewable and Sustainable Energy Reviews, 2020
Abstract The zinc bromine redox flow battery (ZBFB) is a promising battery technology because of its potentially lower cost, higher efficiency, and relatively long life-time. However, for large-scale applications the formation of zinc dendrites in ZBFB is of a major concern.

Dendrite Suppression Membranes for Rechargeable Zinc Batteries

ACS Applied Materials & Interfaces, 2018
Aqueous batteries with zinc metal anodes are promising alternatives to Li-ion batteries for grid storage because of their abundance and benefits in cost, safety, and nontoxicity. However, short cyclability due to zinc dendrite growth remains a major obstacle.

The critical overpotential for zinc dendrite formation

Journal of Applied Electrochemistry, 1979
The critical overpotential for zinc dendrite growth is determined as 173 mV by the method described by Popovet al. [1]. It was shown that this procedure can be applied successfully to metal deposition processes when there is a large codeposition of hydrogen.

Additives for Suppressing Zinc Dendrites in Rechargeable Zinc Metal Batteries

ECS Meeting Abstracts, 2015
Rechargeable zinc-based battery systems hold great promise for future energy storage devices due to their low cost and high theoretical energy density.1 However, the development of portable or stationary rechargeable zinc batteries has been hindered by several critical issues.

Revealing the Two‐Dimensional Surface Diffusion Mechanism for Zinc Dendrite Formation on Zinc Anode

Small, 2021
AbstractAqueous zinc‐ion battery is regarded as one of the promising devices for large‐scale energy storage systems owing to its high safety, cost‐effectiveness, and competitive electrochemical properties. However, the dendrite growth on zinc metal anodes dramatically hinders its further practical applications, and the internal mechanism of dendrite ...

In-situ regulation of zinc metal surface for Dendrite-Free Zinc-ion hybrid supercapacitors

Journal of Colloid and Interface Science, 2022
Aqueous Zn-ion hybrid supercapacitors (ZHSCs) combine the high power density of supercapacitors with the high energy density of batteries. However, the growth of dendrite and spontaneous Zn corrosion damage the service life of ZHSCs and further seriously restrict their large-scale application in energy storage fields.

Zinc induced apoptotic death of mouse dendritic cells

Apoptosis, 2010
Zinc ions (Zn(2+)) are food components with favourable effects in infectious disease. Zn(2+) is taken up into dendritic cells (DCs), key players in the regulation of innate and adaptive immunity. In other cell types, Zn(2+) has been shown to stimulate the formation of ceramide, which is in turn known to trigger suicidal cell death.

Zinc electrode with reduced dendritic propagation

Journal of Power Sources, 2007
Microporous separators conventionally used in lead-acid accumulators are proposed to substitute rayon-type separator during discharge of zinc anode alkaline accumulators, while the same accumulator is charged mainly through rayon-type separator. Thus the positive qualities of rayon-type and microporous-type separators are amalgamated.
