Machine‐Learning‐Enabled Wood with Nanopump Functionalization for Solar Interfacial Evaporation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study employed machine learning to design an iron‐cobalt‐carbon‐wood photothermal material, achieving high‐efficiency evaporation at 2.807 kg m−2 h−1 and excellent salt resistance. The integrated system increased the daily water production efficiency of solar distillation by 1.5 times, providing an innovative solution for sustainable seawater ...

Hydrophobic eutectic solvent‐engineered membranes for highly permeable, selective, and antifouling pharmaceutical removal from municipal wastewater

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Single‐step incorporation of a hydrophobic deep eutectic solvent (HDES) into polyethersulfone ultrafiltration membranes via non‐solvent induced phase separation creates selective, antifouling membranes for pharmaceutical removal. The HDES nanodomains enhance permeability, electrostatic interactions, and adsorption affinity, enabling efficient and ...

Multi‐synergistic strategy for dual‐sensing conductive hydrogels capable of simultaneous strain and temperature monitoring

open access: yesFlexMat, EarlyView.
In this study, a multicomponent synergistic strategy is utilized, which capitalizes on the “intersection” of multiple functional influencing factors to achieve the successful development of a multifunctional hydrogel. Through the construction of a unique three‐dimensional dynamic cross‐linked network, the material combines mechanical strength ...

Tracking of Low Radar Cross-Section Super-Sonic Objects Using Millimeter Wavelength Doppler Radar and Adaptive Digital Signal Processing

open access: yesRemote Sensing
Small targets with low radar cross-section (RCS) and high velocities are very hard to track by radar as long as the frequent variations in speed and location demand shorten the integration temporal window.

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

open access: yesLaser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.
