Metallic 1T Phase MoS Nanosheets Covalently Functionalized with BBD Molecules for Enhanced Supercapacitor Performances.

Metallic 1T phase molybdenum disulfide (MoS) is among the most promising electrode materials for supercapacitors, but its capacitance and cyclability remain to be improved to meet the constantly increasing energy storage needs in portable electronics. In this study, we present a strategy, covalent functionalization, which achieves the improvement of capacitance of metallic 1T phase MoS. Covalently functionalized by the modifier 4-bromobenzenediazonium tetrafluoroborate, the metallic MoS membrane exhibits increased interlayer spacing, slightly curled layered architecture, enhanced charge transfer, and improved adsorption capabilities toward electrolyte molecules and ions.

Advances in Electrochemical Liquid-Phase Transmission Electron Microscopy for Visualizing Rechargeable Battery Reactions.

This review presents an overview of the application of electrochemical liquid-phase transmission electron microscopy (ELP-TEM) in visualizing rechargeable battery reactions. The technique provides atomic-scale spatial resolution and real-time temporal resolution, enabling direct observation and analysis of battery materials and processes under realistic working conditions. The review highlights key findings and insights obtained by ELP-TEM on the electrochemical reaction mechanisms and discusses the current limitations and future prospects of ELP-TEM, including improvements in spatial and temporal resolution and the expansion of the scope of materials and systems that can be studied.

Identification of R2R3-MYB family in blueberry and its potential involvement of anthocyanin biosynthesis in fruits.

Background: Blueberries (Vaccinium corymbosum) are regarded as "superfoods" attributed to large amounts of anthocyanins, a group of flavonoid metabolites, which provide pigmentation in plant and beneficial effects for human health. MYB transcription factor is one of vital components in the regulation of plant secondary metabolism, which occupies a dominant position in the regulatory network of anthocyanin biosynthesis. However, the role of MYB family in blueberry responding to anthocyanin biosynthesis remains elusive.

Building Homogenous Li TiO Coating Layer on Primary Particles to Stabilize Li-Rich Mn-Based Cathode Materials.

Li-rich Mn-based oxides (LRMOs) are promising cathode materials for next-generation lithium-ion batteries (LIBs) with high specific energy (≈900 Wh kg ) because of anionic redox contribution. However, LRMOs suffer from issues such as irreversible release of lattice oxygen, transition metal (TM) dissolution, and parasitic cathode-electrolyte reactions. Herein, a facile, scalable route to build homogenous and ultrathin Li TiO (LTO) coating layer on the primary particles of LRMO through molten salt (LiCl) assisted solid-liquid reaction between TiO and Li Mn Co Ni O is reported.

A Zn(ClO) Electrolyte Enabling Long-Life Zinc Metal Electrodes for Rechargeable Aqueous Zinc Batteries.

The degradation or dendrite formation of zinc metal electrodes has shown to limit the cycle life of rechargeable aqueous zinc batteries, and a few anode protection methods are proposed. We herein demonstrate that, except for external protections, a simple design of an electrolyte can effectively promote stable and facile Zn stripping/plating from/on zinc electrodes. By using Zn(ClO) in the aqueous electrolyte, reversible Zn stripping/plating is achieved for over 3000 h at 1 mA cm current density and 1 mA h cm capacity, superior to the conventional ZnSO electrolyte.
