3D Printing of Auxetic Self‐powered Mechanoluminescent Photonic Skins for Underwater Communication and Safety Monitoring

open access: yesAdvanced Materials, EarlyView.
A 3D‐printed self‐powered auxetic mechanoluminescent photonic skin for underwater communication and safety monitoring is introduced. Its auxetic structures, with a negative Poisson's ratio, ensure exceptional conformability to curved surfaces, enhancing adaptability to dynamic underwater environments.

Detecting Cr6+ at ≈100 pM Concentration with Fluorescence Enhancement Signatures in a Novel Eco‐Fluorophore: Matching WHO's 96 pM Recommended Standard for Drinking Water

open access: yesAdvanced Materials, EarlyView.
Through a dual‐functionalization strategy, carbon quantum dots (CQD) with exceptional fluorescence properties are engineered. These CQD are integrated with graphitic carbon nitride to form a 2D/2D heterostructure via both covalent and non‐covalent modification.

A Machine Learning Framework to Forecast Wave Conditions [PDF]

open access: yesarXiv, 2017
A~machine learning framework is developed to estimate ocean-wave conditions. By supervised training of machine learning models on many thousands of iterations of a physics-based wave model, accurate representations of significant wave heights and period can be used to predict ocean conditions.

Synthetic Chromatophores for Color and Pattern Morphing Skins

open access: yesAdvanced Materials, EarlyView.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

OTEC ocean engineering technology development [PDF]

open access: yesOCEANS 82, 1982
Ocean Thermal Energy Conversion (OTEC) is the principal ocean energy source under development by the U. S. Department of Energy (DOE) because of its potential, state of development, and availability and access of the resource to the U. S. The major features of OTEC are that the source is renewable with minimum impact on the environment, and the ...
