  • Probing Contact-Electrification-Induced Electron and Ion Transfers at a Liquid–Solid Interface
    As a well-known phenomenon, contact electrification (CE) has been studied for decades. Although recent studies have proven that CE between two solids is primarily due to electron transfer, the mechanism for CE between liquid and solid remains controversial. The CE process between different liquids and polytetrafluor......

  • Wireless Monitoring Using a Stretchable and Transparent Sensor Sheet Containing Metal Nanowires
    Mechanically and visually imperceptible sensor sheets integrated with light-weight wireless loggers are employed in ultimate flexible hybrid electronics (FHE) to reduce vital stress/nervousness and monitor natural biosignal responses. The key technologies and applications for conceptual sensor system fabrication are......

  • Acoustic Holographic Cell Patterning in a Biocompatible Hydrogel
    Acoustophoresis is promising as a rapid, biocompatible, noncontact cell manipulation method, where cells are arranged along the nodes or antinodes of the acoustic field. Typically, the acoustic field is formed in a resonator, which results in highly symmetric regular patterns. However, arbitrary, nonsymmetrically sh......

  • Hierarchically oriented organization in supramolecular peptide crystals
    Hierarchical self-assembly and crystallization with long-range ordered spatial arrangement is ubiquitous in nature and plays an essential role in the regulation of structures and biological functions. Inspired by the multiscale hierarchical structures in biology, tremendous efforts have been devoted to the u......

  • Metal-coordinated sub-10 nm membranes for water purification
    ltrathin membranes with potentially high permeability are urgently demanded in water purification. However, their facile, controllable fabrication remains a grand challenge. Herein, we demonstrate a metal-coordinated approach towards defect-free and robust membranes with sub-10 nm thickness. Ph......

  • Unwinding a spiral of cellulose nanocrystals for stimuli-responsive stretchable optics
    Unwinding a spiral of cellulose nanocrystals for stimuli-responsive stretchable opticsCellulose nanocrystals (CNCs) derived from biomass spontaneously organize into a helical arrangement, termed a chiral nematic structure. This structure mimics the organization of chitin found in the exoskele......

  • Electrochemically reconfigurable architected materials
    Architected materials can actively respond to external stimuli—such as mechanical forces, hydration and magnetic fields—by changing their geometries and thereby achieve novel functionalities. Such transformations are usually binary and volatile because they toggle between ‘on’ and ‘off’ states and require pe......

  • Self-Sterilizing Laser-Induced Graphene Bacterial Air Filter
    Nosocomial infections transmitted through airborne, droplet, aerosol, and particulate-transported modes pose substantial infection risks to patients and healthcare employees. In this study, we demonstrate a self-cleaning filter comprised of laser-induced graphene (LIG), a porous conductive graphene foam form......

  • A multifunctional shape-morphing elastomer with liquid metal inclusions
    Natural soft tissue achieves a rich variety of functionality through a hierarchy of molecular, microscale, and mesoscale structures and ordering. Inspired by such architectures, we introduce a soft, multifunctional composite capable of a unique combination of sensing, mechanically robust electronic connectiv......
