Membranes, Journal Year: 2025, Volume and Issue: 15(2), P. 46 - 46

Published: Feb. 4, 2025

Water in membrane interphases is vital for cellular biological functions, but despite its importance, the structure and function of water remain elusive. Here, by studying OH stretching mode partially hydrated lipid multilayers FTIR measurements, relevant information on near surface with membranes has been gathered. The hydrogen bond network highly perturbed first layers that are contact membrane, exhibiting strong deviations from tetrahedral symmetry a significant number defects, such as isolated molecules large hydrogen-bonded dimers interphase region. These findings support hypothesis chains form phospholipid membranes, involved proton transfer across bilayers phosphate groups opposing lipids. Furthermore, we have determined even at very low hydration levels, small amount embedded within confined spaces hydrocarbon region bilayers, which could potentially contribute to structural stability membrane.

Abstract Aqueous zinc‐ion batteries (AZIBs) are a promising alternative to lithium‐ion batteries, boasting superior safety, eco‐friendliness, and cost‐effectiveness. Despite these advantages, performance issues such as irregular Zn deposition cathode material dissolution remain challenging.

The synergistic effect of structure high water affinity APHE effectively suppress water‐induced parasitic reactions. In brief, the promotes rapid 2+ ion diffusion, leading uniform flux. Additionally, abundant hydroxyl groups in facilitate dissociation adjust solvation structure, setting it apart from isotropic matrix. Furthermore, improvement diffusion tortuosity enhances electrode/electrolyte kinetics, thereby improving rate‐capability reversibility (de)‐intercalation. Thus, demonstrates thin dense layer 31.7 µm, which is less than half thickness IPHE (67.5 µm) after 500 cycles. research addresses fundamental challenges AZIBs provides valuable insights into design advanced electrolytes for future energy storage systems.

Hydrogen bonds (H-bonds) are pivotal in various chemical and biological systems exhibit complex behavior under external perturbations. This study investigates the structural, vibrational, energetic properties of prototypical H-bonded dimers, water (H2O)2, hydrogen fluoride (HF)2, sulfide (H2S)2, ammonia (NH3)2 - respective monomers static homogeneous electric fields (EFs) using accurate explicitly correlated singles doubles coupled cluster method (CCSD) for equilibrium geometries harmonic vibrational frequencies perturbative triples CCSD(T) energies. As response H2O, HF, H2S, NH3 monomers, it turns out that dipole derivatives primarily govern geometry relaxation. Perturbation theory including cubic anharmonicity can reproduce CCSD results on Stark effect, except NH3, where deviations arise due to its floppiness. The field-induced modifications H-bond lengths, effects, binding energies, charge-transfer mechanisms dimers elucidated. Symmetry-adapted perturbation (SAPT) analysis reveals electrostatics dominates stabilization H-bonds across all field strengths, while induction contributions increase significantly with stronger fields, particularly more polarizable atoms. Our reveal a universal strengthening intermolecular interactions at moderate strong intensities significant variability among inherent differences molecular polarizability charge distribution. Notably, direct correlation is observed between energies effect stretching mode donor molecule, both relation energy term, investigated dimers. All these findings provide insights into EF-driven modulation H-bonds, highlighting implications catalysis, hydrogen-based technologies, processes.
