Review of Underwater

Open Rivers Rethinking Water Place & Community, 2022
Underwater is surprising. Lois Hendrickson and Emily Beck, the exhibit’s curators, planned the exhibit after a visitor asked if the Wangensteen Historical Library of Biology and Medicine’s expansive collection included any materials related to algae.

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Tissue Engineered Human Elastic Cartilage From Primary Auricular Chondrocytes for Ear Reconstruction

Advanced Functional Materials, EarlyView.
Despite over three decades of research, no tissue‐engineered solution for auricular reconstruction in microtia patients has reached clinical translation. The key challenge lies in generating functional elastic cartilage ex vivo. Here, we integrate synergistic cell‐biomaterial strategies to engineer auricular grafts with mechanical and histological ...

Underwater Bearing-Only and Bearing-Doppler Target Tracking Based on Square Root Unscented Kalman Filter

Entropy, 2019
Underwater target tracking system can be kept covert using the bearing-only or the bearing-Doppler measurements (passive measurements), which will reduce the risk of been detected.

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

Advanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Scene-Driven Semantic Alignment for Generative Communication in Underwater Images

IET Signal Processing
Underwater images serve as one of the most intuitive media for human perception of underwater environments. However, the limited bandwidth and susceptibility to noise in underwater acoustic (UWA) channels pose significant challenges for traditional image

Underwater Multi-Vehicle Trajectory Alignment and Mapping Using Acoustic and Optical Constraints

Sensors, 2016
Multi-robot formations are an important advance in recent robotic developments, as they allow a group of robots to merge their capacities and perform surveys in a more convenient way.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

Advanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs

Advanced Functional Materials, EarlyView.
OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...

Design and Implementation of an Underwater Telemetric Glucose Monitoring System for Scuba Divers

Hittite Journal of Science and Engineering, 2018
Despite the abundance of telemetric applications for ecology, behaviour and physiology of marine life, few efforts were reported about the use of acoustic telemetry for SCUBA divers.
