Tailoring Water-in-DMSO Electrolyte for Ultra-stable Rechargeable Zinc Batteries.
Angew Chem Int Ed Engl
January 2025
Institute of Energy Material Science, University of Shanghai for Science and Technology, Shanghai, 200093, China.
Rechargeable zinc batteries (RZBs) are hindered by two primary challenges: instability of Zn anode and deterioration of the cathode structure in traditional aqueous electrolytes, largely attributable to the decomposition of active HO. Here, we design and synthesize a non-flammable water-in-dimethyl sulfoxide electrolyte to address these issues. X-ray absorption spectroscopy, in situ techniques and computational simulations demonstrate that the activity of HO in this electrolyte is extremely compressed, which not only suppresses the side reactions and increases the reversibility of Zn anode, but also diminishes the cathode dissolution and proton intercalation.

Article Synopsis
- Glioblastoma (GBM) is a significant public health issue partly due to challenges in delivering effective treatments like doxorubicin (DOX) through the blood-brain barrier.
- Two novel DOX glycoconjugates, synthesized with oxime linkages, were shown to maintain the drug's ability to intercalate with DNA, enhancing their effectiveness against GBM cells.
- These glycoconjugates demonstrated improved cytotoxic effects compared to standard DOX in both GBM cell lines and a blood-brain barrier model, suggesting that glucose conjugation could enhance chemotherapy outcomes for GBM patients.
Localized High-Concentration Electrolyte for All-Carbon Rechargeable Dual-Ion Batteries with Durable Interfacial Chemistry.
Angew Chem Int Ed Engl
January 2025
College of Chemistry, Huazhong Agricultural University, Wuhan, 430070, P. R. China.
Lithium-based rechargeable dual-ion batteries (DIBs) based on graphite anode-cathode combinations have received much attention due to their high resource abundance and low cost. Currently, the practical realization of the batteries is hindered by easy oxidation of the electrolyte at the cathode interface, and solvent co-intercalation at the anode-electrolyte interface. Configuration of a "solvent-in-salt" electrolyte with a high concentration of Li salt is expected to stabilize the electrolyte chemistry versus both electrodes, yet inevitably reduces the mobility of the solvated working ions and increases the cost of the electrolyte.

Nanoengineered Systems Laboratory, UCL Mechanical Engineering, University College London, London, WC1E 7JE, UK.
Slippery lubricant infused porous surfaces (SLIPS) have the potential to address daunting challenges such as undesirable surface fouling/biofouling, icing, etc. However, the depletion of lubricants hampers their practical utility. As a solution, here a rational strategy is introduced that operates synergistically in three parts.

This research highlights the efficacy of NaNbO as a coating for P2-NaNiMnO cathodes in sodium-ion batteries. The coating enhances the kinetic behavior and cyclability of the electrochemical cells, as shown by electrochemical measurements. XRD analysis indicates that Nb does not incorporate into the cathode structure, implying a physical interaction between the coating and the cathode material.
