Removal of Steroid Hormone Micropollutants by an Electrochemical Carbon Nanotube Membrane Flow‐Through Reactor: Role of Concentration and Degradation Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
A flow‐through electrochemical membrane reactor equipped with a carbon nanotube membrane eliminates the mass transfer limitation, achieving removals >97.5% for steroid hormone (SH) micropollutants through electrochemical adsorption and degradation, over a broad initial concentration varying from 50 to 106 ng L−1.

Bilayer Solar Crystallizer by a Directional Liquid Transport Fabric for Stable Brine Treatment and Ion Recycling

open access: yesAdvanced Functional Materials, EarlyView.
The unique brine transportation and salt crystallization behavior, that is, the salt is preferred to be crystallized on the surface of the directional liquid transportation fabric, is discovered and investigated in this work. Abstract Directional and asymmetric liquid transport (DALT) materials are promising for human moisture management and ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Photoresponsive Gas‐Permeable Membranes: Fundamentals, Innovations, and Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Photoresponsive gas‐permeable membranes can be potentially used for smart packing, carbon capture, hydrogen purification, and optical gas valves due to their remote and non‐contact activation, precise spatial and temporal control, and reversible switching capabilities.

Use of in-filled trenches to screen ground vibration due to impact pile driving: experimental and numerical study

open access: yesHeliyon, 2018
Vibration generated by pile driving can cause discomfort to occupants of nearby buildings and disturb the activities carried out in the buildings. The transmitted vibration will depend on both the source and the transmitting medium (soil), while the ...

Artificial Compound Eye for Clear Vision in Harsh Environment

open access: yesAdvanced Functional Materials, EarlyView.
Artificial compound eye (CE) with exceptional imaging and motion tracking capturing the movement of a spider and swinging thread with a wide field of view. Surface modifications ensure clear vision of alphabetic letters in rain and fog. Images captured in fog with CE remains visible 3 times longer than simple eyes (SE).
