Abstract Accurate measurement of complicated multiphase flow is crucial to the safety and efficiency petroleum chemical industrial facilities. However, existing detection techniques are not applicable pipelines in remote regions including deserts or deep seas, due high cost providing a stable power supply. Herein, self‐powered sensor, composed liquid‐driven triboelectric nanogenerator (TENG) ‐based signal generator, ring‐type transmitter, string‐type receiver, proposed. Theoretical modeling displacement current between transmitter receiver implies that received can accurately reflect wetting state validated by combined experimental (accuracy above 97%) simulation study. Coupling with quantitative analysis algorithm, system numerous points developed precisely monitor various parameters, slug frequency (one point), length (two points), pattern (four which verified spontaneous high‐speed camera recordings water–air flow. The present work provides paradigm‐shift way develop self‐powered, inexpensive, accurate technique detect at

Abstract Replacing the oxygen evolution reaction with thermodynamically more favorable alternative oxidation reactions offers a promising to reduce energy consumption of hydrogen production. However, questions remain regarding economic viability for industrial‐scale Here, we propose an innovative cost‐effective, environment‐friendly and energy‐efficient strategy simultaneous recycling spent LiFePO 4 (LFP) batteries production by coupling LFP‐assisted ferricyanide/ferrocyanide ([Fe(CN) 6 ] 4− /[Fe(CN) 3− ) redox reaction. The onset potential electrooxidation [Fe(CN) is low at 0.87 V. Operando Raman UV/Visible spectroscopy confirm that presence LFP in electrolyte allows rapid reduction , thereby completing cycle as well facilitating conversion into LiOH ⋅ H 2 O FePO . electrolyzer consumes 3.6 kWh electricity per cubic meter produced 300 mA cm −2 which 43 % less than conventional water electrolysis. Additionally, this pathway not only minimizes chemical prevents secondary pollution but also presents significant benefits.

Abstract Triboelectric nanogenerator (TENG) offers a novel approach for converting high‐entropy mechanical energy into electrical energy, yet achieving high charge density remains critical. Optimizations using dielectrics with specific capacitance have mitigated air breakdown, but loss within persists as limiting factor. Here, based on poly(vinylidene fluoride–trifluoroethylene–chlorofluoroethylene) (P(VDF‐TrFE‐CFE)) capacitance, composites’ trap and are engineered high‐polarity interfaces from barium titanate (BTO) nanoparticles dense chain segment stacking induced by electrostatic interaction polyetherimide (PEI) to enhance retention capability. With modified interfacial traps, an ultrahigh of 9.23 mC m −2 is achieved in external excitation (ECE) TENG 0.2 vol% PEI/P(VDF‐TrFE‐CFE) film, marking the highest reported single‐unit TENGs. This work provides material strategies high‐performance TENGs, paving way their large‐scale practical applications.
