Nevertheless, poor conductivity and substantial volume changes during cycling restrict their widespread implementation. We hypothesize that combining vertically aligned carbon nanotube arrays (VACNTs), which serve as a conductive scaffold, with a citric-acid-derived carbon coating creates a dual‑carbon architecture that improves the cycling stability and charge transport of SnO₂, thereby enhancing lithium storage performance. To verify this hypothesis, we employ a single-step interfacial functionalization strategy. This approach involves the in situ growth of SnO₂ from a SnCl₄·5H₂O precursor on VACNTs, followed by in situ carbon coating using citric acid as the carbon source, ultimately constructing a dual‑carbon-structured SnO₂/VACNTs@C composite. Within this structure, SnO₂ nanoparticles are uniformly embedded in the VACNTs scaffold. This confined geometry effectively accommodates volume changes during lithiation/ delithiation, and the strong SnO₂/VACNTs interfacial bonding enhances mechanical integrity and electrical conductivity. As a result, the SnO₂/VACNTs@C anode demonstrates superior reversible capacity and rate performance compared to both pure SnO₂ and uncoated SnO₂/VACNTs electrodes. Compared with pristine SnO₂, the material achieves a substantial improvement in lithium-ion diffusion coefficient. Paired with a LiFePO₄ cathode in a full-cell configuration, it further delivers robust cycling stability, notable capacity retention, and competitive energy and power densities.

Herein, we report the rational design and synthesis of a series of Vanadium trioxide/Vanadium nitride (V₂O₃/VN) heterostructured composites through a controlled partial nitridation process using a vanadium-based metal-organic framework as a precursor. This strategy enables the in-situ formation of a conductive carbon matrix and the construction of an intimate heterointerface between V₂O₃ and VN. A key innovation lies in the precise tuning of the V₂O₃-to-VN ratio, which governs the heterostructure morphology, defect concentration, and resulting electrochemical properties. The optimized V₂O₃/VN composite leverages the complementary attributes of its constituents: the structural stability and high theoretical capacity of V₂O₃, along with the superior electrical conductivity and electrochemical activity of VN. Synergistic effects at the heterointerface not only facilitate rapid electron and ion transport but also effectively accommodate volume variations during repeated cycling. Moreover, the presence of oxygen vacancies enhances Zn²⁺ adsorption and diffusion kinetics. Therefore, the V₂O₃/VN cathode delivers a high specific capacity of 528 mAh g^-1 at 0.1 A g^-1, and retains 244 mAh g^-1 after 2000 cycles at 5 A g^-1, corresponding to a capacity fading rate of 0.025% per cycle.

The redox-active dopants not only contribute additional capacity to the composite but also modulate the morphology and electronic structure of the polymer, thereby enhancing both ion and electron transport. Moreover, the strong interactions between heptamolybdate and the I-based species not only effectively confine the dopants within the PPy matrix, preventing counterion depletion, but also facilitate the redox kinetics of iodine.

Although several theories have been proposed to explain the extraordinary longevity of nanobubbles-a behavior not predicted by classical models-this phenomenon remains the subject of active debate. Nevertheless, there is broad consensus that nanobubble stability primarily arises from strong surface electric charge associated with interfacial phenomena, leading to localized water dissociation in the vicinity of the nanobubble. The water dissociation driven by nanobubbles has prompted speculation regarding the possibility of power generation through a hydroelectric cell, potentially enabling an alternative long-term, large-scale energy storage pathway that has not yet been explored. However, despite its conceptual appeal, any quantitative estimation of the efficiency of such a system, if feasible at all, has not been established. Here, utilizing the linearized Poisson-Boltzmann (Debye-Hückel) approximation and first-order perturbations in the nanobubble surface potential, an analytical expression for the maximum efficiency of a hydroelectric nanobubble-driven cell is derived. It is shown that a maximum efficiency of  ≃ 12% can be achieved at best, with predicted current densities remaining within the same order of magnitude as those reported for conventional hydroelectric-cell systems based on nanoporous ferrites.
