Solar vapor generation through evaporation using photothermal materials is a promising candidate for seawater desalination. The TiC MXene membrane has exhibited photothermal behavior in solar water evaporation. However, dense packed two-dimensional (2D) MXene membrane with high reflection loss and insufficient vapor escape channels limited its solar evaporation performance. In this work, one-dimensional (1D) multi-walled carbon nanotubes (MWCNT) were added into 2D TiC nanosheets as the holder to form a 2D/1D hybrid photothermal membrane. Owing to the 2D/1D hybrid structure, more effective broadband solar absorption, water transportation and vapor escape were achieved.

Solar-driven desalination has emerged as a sustainable and efficient solution for addressing global water scarcity, especially beneficial in remote, off-grid, and disaster-affected regions. Among emerging technologies, photothermal membrane distillation (PMD) stands out due to its effective solar-energy conversion, scalability, and simplicity. Here, we report a hybrid PMD membrane fabricated by electrospinning MXene (TiCT) nanosheets integrated with silver nanoparticles (AgNPs) onto a poly(vinylidene fluoride--hexafluoropropylene) (PH) substrate.

Seawater electrolysis offers a sustainable pathway for green hydrogen production, but chloride-induced side reactions, particularly chlorine evolution (ClER), limit the stability and efficiency of catalysts. Based on an interface-engineering strategy, a bifunctional CoP-MXene electrocatalyst was designed and fabricated, in which electrons are transferred from the Ti sites of the MXene support to the adjacent Co active centers of CoP. This directional electron donation modulates the Co electronic structure, generating electron-rich Co sites that effectively suppress Cl adsorption via electronic repulsion while preserving the OH reaction pathways through favorable proton-electron coupling.

Precise, timely, and personalized in vivo thrombus monitoring is critical for improving the treatment effectiveness and clinical outcomes of cardiovascular diseases (CVDs). Terahertz (THz) spectroscopy has become increasingly important as a novel tool in biomedical engineering due to its rapid analysis ability, high temporal resolution, and label-free measurement modality. However, achieving high thrombus sensing performance in real blood environments remains a significant challenge.

Achieving efficient ion transport in thick electrodes remains a fundamental challenge in electrochemical systems with high energy density, primarily due to prolonged diffusion pathways and poorly integrated architectures. Leveraging the nanoconfinement effect, (sub)nanoscale channels can significantly accelerate ion transport kinetics to maximize electrochemical performance. Inspired by the hierarchical network structure of bamboo membrane, a gradient nanoconfined MXene electrode (GNC-MX) is designed, where multiscale interlayer spacing is coupled with in-plane mesopores that bridge adjacent nanoconfined channels, enabling synergistic vertical and horizontal ion migration.

The exponential growth of the global population in the digital era has accelerated urbanization and industrialization, leading to severe complex water pollution from the discharge of toxic dyes into aquatic ecosystems. Two dimensional (2D) MXene-based nano-adsorbents recently emerged as promising candidates for developing sustainable wastewater remediation technologies due to their tunable physicochemical properties, including a high negative zeta potential, a large specific surface area, exceptional adsorption capacity, superior electrical and thermal conductivity, hydrophilicity, and rich surface chemistry. Strategic optimization approaches for MXenes, encompassing interlayer spacing modification, surface engineering, stoichiometric tuning, morphological control, bandgap engineering, membrane fabrication, hybridization, and functionalization, have significantly enhanced their adsorptive performance and dye removal efficiency for real-time wastewater treatment applications.
