A Self‐Cleaning Solar Evaporator Based on MXene/Aramid Nanofiber Aerogels for Efficient Water Desalination

open access: yesAdvanced Materials Interfaces, EarlyView.
This study develops a self‐cleaning solar evaporator based on MXene‐coated aramid nanofiber aerogels for efficient desalination under high‐salinity conditions. The cylindrical evaporator combines strong photothermal conversion, capillary water transport, and self‐rotation triggered by salt accumulation.

Background and summary: a new focus on groundwater-seawater interactions

open access: yes, 2007
Water and chemical fluxes across the sea floor provide an important linkage between terrestrial and marine environments. Oceanographers recognize that these fluxes may act as a source of nutrients or other harmful contaminants to marine systems (e.g ...

Toward Mechanical Intelligence in Robotics

open access: yesAdvanced Robotics Research, EarlyView.
Robots can use their physical bodies to perform functions usually assigned to electronic sensors and controllers. This perspective defines mechanical intelligence through three core operations: filtering inputs, routing mechanical signals, and switching between states.
