CeO2‐Based Electrocatalysts for the Oxygen Evolution Reaction: Design, Dynamic Mechanisms, and Electrolyte Adaptability

Advanced Science, EarlyView.
This Review shows how cerium oxide helps water‐splitting catalysts work better and last longer. It explains how CeO2 tunes electronic structure, oxygen‐vacancy behavior, and surface reconstruction, while adapting to alkaline, acidic, and seawater conditions.

Analysis of radial oscillations of gas bubbles in Newtonian or viscoelastic mediums under acoustic excitation [PDF]

Acoustic cavitation plays an important role in a broad range of biomedical, chemical and oceanic engineering problems. For example, kidney stone can be crushed into the powder (being discharged naturally) by the acoustic cavitation generated by carefully

Mechanism of Direct Acoustic Construction and Gradient Properties Tuning

Advanced Science, EarlyView.
Directed acoustic construction enables omnidirectional gradient tuning of fingerprint‐inspired microstructures. By investigating the DAC mechanisms, diamond particles are found to enhance acoustic physical, mechanical, and chemical effects, promoting acoustic curing and broadening the range of gradient property tuning.

Interface‐Confined Cavitation at an MXene/TiO2 Schottky Heterointerface for Non‐Thermal Juice Preservation

Advanced Science, EarlyView.
This work establishes an MXene/TiO2 Schottky heterointerface for non‐thermal sonocatalysis. Interface‐confined cavitation and dynamic Ti3+/V₀ shuttles drive charge transport and reactive oxygen species (ROS) generation. The platform achieves 3‐log pathogen reduction while retaining heat‐labile nutrients in complex food matrices, redefining sonocatalyst

Trash to Treasure: PFAS‐Functionalized MOFs for Boosted Piezocatalytic H2 Production

Advanced Energy Materials, EarlyView.
A novel pollutant‐as‐functional‐additive strategy is developed via postsynthetic modification of MOF‐808(Hf) with perfluorohexanoic acid (PFHxA), a typical PFAS pollutant. The modification boosts the dipole moment of the MOFs, enhances their piezoelectricity to promote efficient electron‐hole separation, thus delivering ultrahigh piezocatalytic ...

Study of cavitation bubble collapse near a rigid boundary with a multi-relaxation-time pseudo-potential lattice Boltzmann method

AIP Advances, 2020
Due to the complex phase change and heat transfer processes, the mechanisms of cavitation bubble collapse near a rigid boundary are well recognized to be complicated.

Cavitation regime detection through Proper Orthogonal Decomposition: dynamics analysis of the sheet cavity on a grooved convergent-divergent nozzle [PDF]

, 2014
The unsteady character of the sheet cavity dynamics on the suction side of hydrofoils, on convergent–divergent nozzles or on blades in turbines and propellers is responsible for many issues like erosion, noise and vibrations. This two-phase flow dynamics

Chloride‐Mediated Activation of Aluminum‐Alloyed Liquid Metal Anodes for Stretchable Asymmetric Energy Storage

Advanced Energy Materials, EarlyView.
A gallium‐centered cell pairs an aluminum‐alloyed GaIn anode with a GaOOH cathode in a chloride‐rich water‐in‐ionic‐liquid electrolyte. Chlorogallate ions dissolve the native oxide that normally seals the liquid metal, and preferentially reduce indium seeds to oxide‐free clusters on which gallium plates and strips reversibly.
