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.

Chitin‐Chitosan Cryogels for the Reversible Sequestration and Recovery of Heavy Metals From Wastewater

open access: yesAdvanced Materials Technologies, EarlyView.
Chitin‐chitosan cryogels with degrees of N‐acetylation from 12.2% to 71.4% are fabricated by dissolution, coagulation and lyophilization for the sequestration of heavy metals from water. Colorimetry and differential pulse voltammetry showed controlled adsorption and desorption capacities for As5+, Co2+ and Cu2+, making this material attractive for ...

A Fully Lithography‐Free Fabrication Strategy for Organic Electrochemical Transistors

open access: yesAdvanced Materials Technologies, EarlyView.
A fully lithography‐free fabrication strategy for organic electrochemical transistors (OECTs) is developed, eliminating the need for photolithography and other cleanroom‐based processes. By combining a laser‐cut polymer mask with a dual‐layer tape process, the proposed strategy enables simple and accessible fabrication, facilitating rapid OECT ...

Ultra‐Radiostable Covalent Conformationally Interlocked Networks Enabling a Universal Radiometal‐Labeling Platform for Cancer Radioembolization

open access: yesAdvanced Science, EarlyView.
Conjugated poly(imide dioxime)‐based microspheres establish a radiometal coordination‐driven conformational interlocked network with ultra‐high radiostability. This platform enables low‐temperature, multi‐radionuclide labeling for SPECT/PET/MRI imaging and radionuclide therapy. Mechanistic insights from EXAFS and DFT reveal enhanced stability, while in
