A Parameter-Driven Approach to Modulating Chemical Composition in Prussian Blue Analogues Cathodes for Sodium-ion Batteries.

This study explores how various experimental factors, such as temperature, viscosity, and stirring speed, affect Prussian blue analogues (PBAs) material's structural properties and electroneutrality. These factors influence key attributes like sodium ions, vacancies, and water content, which is governed by electroneutrality. Higher temperatures, faster stirring, low viscosity, and high Na+ concentration enhance Na+ incorporation because of the sufficient Na+ supplement, leading to a dense monoclinic structure with fewer vacancies and lower water content.

Electrochemical detection of poly(ADP-ribose) polymerase-1 with silver nanoparticles as signal labels by integrating the advantages of homogeneous reaction with surface-tethered detection.

Poly(ADP-ribose)polymerase-1 (PARP1) could be activated by binding to nucleic acids with specific sequences, thus catalyzing the poly-ADP-ribosylation (PARylation) of target proteins including PARP1 itself. Most of the previously reported electrochemical methods for the determination of PARP1 were relied on the electrostatic interactions, which required the pre-immobilization of DNA on an electrode for the capture of PARP1. Herein, we reported an "immobilization-free" electrochemical strategy for the assays of PARP1 on the basic of avidin-biotin interaction.

An initiator loaded separator triggering polymerization of a poly(1,3-dioxolane) quasi-solid electrolyte for lithium metal batteries.

An polymerization strategy is regarded as a promising approach to fabricate gel polymer electrolytes (GPEs) and improve interface contact between the electrolyte and electrodes, in which the initiator is initially dissolved in the precursor solution. Herein, aluminum trifluoromethanesulfonate (Al(OTf)) is preloaded onto a separator sheet as the initiator to trigger the ring-opening reaction of 1,3-dioxolane (DOL). The polymer matrix near the separator has a higher crystallization degree than that far away from the separator.

Spatially isolating Li reduction from Li deposition a LiSn alloy protective layer for advanced Li metal anodes.

A Li alloy based artificial coating layer can improve the cyclic performance of Li metal anodes. However, the protective mechanism is not well clarified due to multiple components of the artificial layer and complicated interface in liquid electrolytes. Herein, a single-component LiSn alloy layer buffered Li anode is paired with a solid-state polymer electrolyte, where a metallic Sn film is sputtered onto the Li anode and the subsequent alloying reaction leads to the formation of a LiSn phase.

Lithium (Li) metal is considered as an ideal negative electrode material for next-generation secondary batteries; however, the hideous dendrite growth and parasitic reactions hinder the practical applications of Li metal batteries. Herein, a hybrid polymer film composed of polyvinyl alcohol (PVA) and polyacrylic acid (PAA) is adopted as an artificial protective layer to inhibit the dendritic formation and side reactions in Li metal anodes. PVA with large quantities of polar functional groups can induce even distribution of Li ions (Li).

The Pillar Effect of Large-Size Alkaline Ions on the Electrochemical Stability of Sodium Manganese Hexacyanoferrate for Sodium-Ion Batteries.

Sodium manganese hexacyanoferrate (NaMnHCF) is an attractive candidate as a cathode material for sodium-ion batteries due to its low cost and high energy density. However, its practical application is hindered by poor electrochemical stability caused by the Jahn-Teller effect of Mn and the unstable structure of NaMnHCF. Here, this paper aims to address this issue by introducing highly stable AMnHCF (where A = K, Rb, or Cs) through a facile method to composite with NaMnHCF.
