The bonding state of H2O molecules determines the properties of electrolyte, which strongly impacts on the performance of electrode/battery. In this work, we utilized the nucleophilic sites at two ends of the hexanedinitrile (ADN) to coordinate with Zn2+ ions, which could release the bound H2O molecules in the Zn2+-solvation sheath and form a dynamic cross-linked hydrophobic network. This dynamic hydrophobic network can disturb the hydrogen bond between H2O molecules, and confine H2O molecules within the grid to form many "dynamic water microdomain", further inhibiting the activity and decomposition of H2O. Theoretical calculations, Raman and NMR spectra verify that the water microdomain, solvation-sheath structure and the bonding state of H2O molecules can be regulated by the ADN additive. As a result, significant improvements in stability of electrode/battery and dendrite suppression can be achieved. © 2024, The Authors. All rights reserved.

The ambient printing of high-performance and stable perovskite solar cells (PSCs) is crucial for enabling low-cost and energy-efficient industrial fabrication. However, producing high-quality perovskite films via ambient printing remains challenging due to direct exposure to air, which easily induces additional stacking defects and triggers perovskite degradation compared to films fabricated by traditional spin-coating under inert conditions. Here, a multiple molecular interaction strategy is introduced to address this challenge by incorporating a 2-thiazole formamidine hydrochloride (TC) additive, effectively suppressing defect formation during ambient printing. The specific interactions between TC and precursor components, i.e., multiple hydrogen bonds and coordination interactions, could promote the crystallization of α-phase perovskites and reduce cation and anion vacancies simultaneously when drying in air. These endows high-quality ambient-printed perovskite films with large crystalline grains with eliminated nanovoids and low trap-densities, which improve charge carrier dynamics and prevent perovskite decomposition and hydration under thermal/humidity stress during long-term annealing/ambient storage. The unencapsulated PSCs show a high efficiency of 23.72% with good stability, i.e., realizing 92% and 95% efficiency retention after 672 h of annealing at 85 °C in a N2 atmosphere and after 2088 h of storage in ambient air. © 2025 Wiley-VCH GmbH.

A corrosion-resistant and wear-resistant coating was prepared on the inner wall of copper tube by centrifugal self-propagating melting. The surface morphology, composition and phase composition of the ceramic lining FGM coating were analyzed by XRD and SEM, and the synthesis mechanism of the ceramic coating was studied. The results show that the functionally gradient coating is composed of three layers: ceramic inner layer, metal transition layer and copper substrate layer. The surface of ceramic lining is smooth and dense, which is mainly composed of Al2O3, CaF2 and a small amount of Fe Al spinel. The results show that the alumina phase is dendrite like and grows outward perpendicular to the tube wall, and the low melting point phase is evenly distributed in the dendrite gap, which effectively improves the density of the ceramic layer. © 2021 Trans Tech Publications Ltd, Switzerland.
