Scalable assembly of MXene/ANF nanofluidic membranes induced by shear-flow-alignment for giant osmotic energy harvesting

Two-dimensional (2D) nanofluidic membranes have demonstrated extraordinary promise in high-throughput ionic transport systems for water-energy nexus applications. Nevertheless, the inability to engineer macroscopic, structurally ordered 2D membranes with precisely aligned nanocha...

Liquid Metal Multi‐Functional Droplets Enabled High‐Performance Tumor Therapy With Four Synergistic Mechano‐Thermal‐Chemo‐Freezing Effects

ABSTRACT Cryoablation, which induces rapid intracellular ice crystal formation, has been widely used in clinics for treating various tumors, yet monotherapy yields limited efficacy due to inadequate elimination of tumor cells. Here, we proposed an effective synergistic strategy w...

Birch-Type-Reduced Carbazole Anions Enable Redox-Adaptive Super-Reducing Photocatalysis

Abstract Photocatalytic activation of inert chemical bonds is constrained by the redox potential of the catalyst. Here, we report a redox-adaptive photocatalytic strategy in which an electron-rich carbazole photocatalyst, CBZ6, functions as a molecular redox transformer through t...

Toward reliable thermoacoustic power generation: an efficient elastic-membrane-free U-tube liquid metal magnetohydrodynamic generator under acoustic driving

Thermoacoustically-driven liquid metal magnetohydrodynamic generators (LMHDGs) are attractive for reliable power generation in extreme environments. However, this advantage is fundamentally undermined by the common use of elastic membranes to stabilize the gas-liquid interface. E...
