Suppressing Hydrogen Evolution and Dendrite Formation on a Zn Anode by Coating InO with Tailored Affinity to H* and Zn.

To suppress the hydrogen evolution reaction (HER) and dendrite formation on the Zn anode in aqueous Zn-ion batteries, a submicrometer InO coating on the Zn anode (referred to as Zn@InO) was constructed via magnetron sputtering. Density functional theory (DFT) and experimental data show that the InO coating suppresses the HER because of its weaker interactions with H* compared with Zn, inhibiting the Volmer step. At the same time, the InO coating exhibits a moderate affinity for Zn*, higher than that on Zn but lower than that at the InO-Zn interface, thus facilitating the desolvation of the hydrated Zn ions while promoting its deposition on the Zn substrate beneath the InO coating.

Long-Life Quasi-Solid-State Lithium-Oxygen Battery Enabled by the Gel Polymer Electrolyte and Redox Moieties Anchored in the Cathode.

The practical development of Li-O batteries is often hindered by poor cycling stability, which arises from volatile liquid electrolytes, an unstable anode/electrolyte interface, and sluggish reaction kinetics related to LiO. In this study, we design a long-life quasi-solid-state Li-O battery by integrating a gel polymer electrolyte (GPE) with a tetramethylpiperidinyloxy (TEMPO) redox mediator anchored in a poly(2,2,6,6-tetramethylpiperidinyloxy-4-methacrylate) (PTMA) cathode. During cycling, the GPE stabilizes the lithium/electrolyte interface and retains the electrolyte, while the TEMPO moieties anchored in the PTMA cathode effectively enhance the catalytic selectivity for LiO formation and decomposition.

A Separator with Double Layers Individually Modified by LiAlO Solid Electrolyte and Conductive Carbon for High-performance Lithium-Sulfur Batteries.

The "shuttle effect" and the unchecked growth of lithium dendrites during operation in lithium-sulfur (Li-S) batteries seriously impact their practical applications. Besides, the performances of Li-S batteries at high current densities and sulfur loadings hold the key to bridge the gap between laboratory research and practical applications. To address the above issues and facilitate the practical utilization of Li-S batteries, the commercial separator is modified with solid electrolyte (nanorod LiAlO, LAO) and conductive carbon (Super P) to obtain a double coated separator (SPLAOMS).

Risk Stratification with Haemodynamic Gain Index and Peak Rate-Pressure Product in Patients with Chronic Heart Failure Undergoing Treadmill Exercise Testing.

Aims: We recently demonstrated the combined prognostic value of two simple non-invasive parameters obtained from treadmill exercise testing in patients with heart failure (HF) with reduced ejection fraction, the haemodynamic gain index (HGI) and peak rate-pressure product (RPP). However, their prognostic value is yet to be validated in patients with undifferentiated HF syndrome.

Methods: We identified consecutive HF patients undergoing treadmill exercise testing for symptom evaluation between 1/1991-2/2015.

Temperature-Robust Solvation Enabled by Solvent Interactions for Low-Temperature Sodium Metal Batteries.

The broad temperature adaptability associated with the desolvation process remains a formidable challenge for organic electrolytes in rechargeable metal batteries, especially under low-temperature (LT) conditions. Although a traditional approach involves utilizing electrolytes with a high degree of anion participation in the solvation structure, known as weakly solvation electrolytes (WSEs), the solvation structure of these electrolytes is highly susceptible to temperature fluctuations, potentially undermining their LT performance. To address this limitation, we have devised an innovative electrolyte that harnesses the interplay between solvent molecules, effectively blending strong and weak solvents while incorporating anion participation in a solvation structure that remains mostly unchanged by temperature variations.

Fatty Acid Profiles Linked to Organohalogen Exposure in Cetaceans from the Northern South China Sea.

Increasing evidence suggests that organohalogen contaminants (OHCs) could disrupt lipid metabolism in organisms, prompting consideration of fatty acids (FAs) as biological tools for assessing chemical stress in biological systems.

Our results revealed higher OHC levels in these cetaceans than global averages.

Structural Basis of Ultralow Capacitances at Metal-Nonaqueous Solution Interfaces.

Metal-nonaqueous solution interfaces, a key to many electrochemical technologies, including lithium metal batteries, are much less understood than their aqueous counterparts. Herein, on several metal-nonaqueous solution interfaces, we observe capacitances that are 2 orders of magnitude lower than the usual double-layer capacitance. Combining electrochemical impedance spectroscopy, atomic force microscopy, and physical modeling, we ascribe the ultralow capacitance to an interfacial layer of 10-100 nm above the metal surface.

Development of PFAS-Free Locally Concentrated Ionic Liquid Electrolytes for High-Energy Lithium and Aluminum Metal Batteries.

ConspectusLithium-ion batteries (LIBs) based on graphite anodes are a widely used state-of-the-art battery technology, but their energy density is approaching theoretical limits, prompting interest in lithium-metal batteries (LMBs) that can achieve higher energy density.

Developing electrocatalysts that are resistant to CO and H₂S poisoning has therefore become a critical priority.
