Nanofluidic proton channels based on a 2D layered glass membrane with improved aqueous and acid stability.

Layered two-dimensional (2D) membranes hold great promise in the study of confined ion transport and nanofluidic applications. However, 2D layered membranes suffer from poor stability in water and harsh chemical conditions. Here we use amorphous silica-based nanosheets obtained by vermiculite to assemble a layered glass membrane (LGM) with a 2D nanofluidic channel network in the interlayer space.

Electric field modulated water permeation through laminar TiCT MXene membrane.

Controlling water transport is central to a wide range of water-related energy and environment issues. In particular, enhancing the water permeation is highly demanded for practical membrane applications such as water treatment. In this work, we demonstrate that the water permeation through the laminar and electrically conductive MXene membrane can be facilely modulated with electric field.

Reliable and Low Temperature Actuation of Water and Oil Slugs in Janus Photothermal Slippery Tube.

While actuating liquid with external stimuli on open surfaces has been extensively studied, the actuation in tubes or channels is much more challenging due to the lower accessibility and higher complexity in material/device design, despite its crucial importance for microfluidic applications. Of various potential actuation methods, optical ones are particularly interesting because they can be remotely controlled with high spatial/temporal resolution. Yet, previous optical methods relied on the physical deformation of tubes, raising the concern of material fatigue and compromising reliability.
