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.

Nanoarchitectonics of Metal–Organic Framework and Nanocellulose Composites for Multifunctional Environmental Remediation

open access: yesAdvanced Materials, EarlyView.
Nanoscale metal–organic frameworks (MOFs) and nanocellulose composites have significant potential for the multi‐functional remediation of the environment. This review focused on the synthesis strategies (in situ growth, ex situ growth, and other approaches), typical forms (aerogel, hydrogel, beads, and membrane), and applications in the removal of ...

Self‐Spiking Linear Neuromorphic Soft Pressure Sensor for Underwater Sensing Applications

open access: yesAdvanced Materials, EarlyView.
This study presents a novel design of a neuromorphic pressure sensor that can generate self‐spiking symmetric signals with direct event‐based encoding through the integration of magnetic spheres and alternating coil circuits. The key advantages of this work include high linearity up to 200 kPa (R2 = 0.997), self‐spiking behavior for simplified signal ...

Characteristics of alkali-activated slag powder mixing with seawater: Workability, hydration reaction kinetics and mechanism

open access: yesCase Studies in Construction Materials, 2022
Marine engineering is faced with the problem of shortage of engineering materials. The local use of marine raw materials, such as seawater and sea sand, can greatly promote the development of marine engineering construction.

Marine Engineering (a Text-Book) [PDF]

open access: yesNature, 1908
MARINE engineering has been developed in many directions during recent years, and the influence of these developments upon the design of steamships has been marked. Within a period of fifteen or sixteen years water-tube boilers have practically taken the place of cylindrical (or “tank”) boilers in all classes of warships; steam-turbines have been ...

Phenomenological marine snow model for optical underwater image simulation: Applications to color restoration

open access: yes, 2012
International audienceOptical imaging plays an important role in oceanic science and engineering. However, the design of optical systems and image processing techniques for subsea environment are challenging tasks due to water turbidity.
