Bio‐Inspired Multifunctional Superhydrophilic Coatings With Remarkably Fast Self‐Healing Abilities

Advanced Functional Materials, EarlyView.
We developed bio‐inspired multifunctional hydrogel‐based coatings that exhibit extremely fast/repeatable self‐healing abilities, long‐lasting anti‐fogging performance, superhydrophilicity in air, and underwater superoleophobicity. By doping multivalent metal‐ions into the hydrogel networks, which promoted hydrogen bonding formation and enhanced the ...

Multimodal fusion image enhancement technique and CFEC-YOLOv7 for underwater target detection algorithm research

Frontiers in Neurorobotics
The underwater environment is more complex than that on land, resulting in severe static and dynamic blurring in underwater images, reducing the recognition accuracy of underwater targets and failing to meet the needs of underwater environment detection.

Dynamic Observation of Lacy Pattern Formation in a Bone Tissue Model Using Liquid Phase Scanning Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Here, we establish a low‐dose liquid‐phase electron microscopy workflow for real‐time observation of biological processes in hydrated conditions. Beam damage is reduced by imaging only 20% of the pixels and reconstructing the complete image using an inpainting algorithm.

Underwater Acoustic Target Recognition with a Residual Network and the Optimized Feature Extraction Method

, 2021
Underwater Acoustic Target Recognition (UATR) remains one of the most challenging tasks in underwater signal processing due to the lack of labeled data acquisition, the impact of the time-space varying intrinsic characteristics, and the interference from

APTES‐Mediated Ti‐Squarate MOF/n‐GaN Nanowire Photoanodes for Efficient Photoelectrochemical Water Splitting

Advanced Functional Materials, EarlyView.
The APTES linker establishes a permanent interfacial dipole, reducing the work function of n‐GaN from 3.55 to 3.29 eV. This strengthens the built‐in electric field, significantly accelerating hole extraction to drive the oxygen evolution reaction (OER). Ultimately, this tailored charge‐separation architecture achieves a remarkable 4.78‐fold enhancement

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

Advanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...
