Modeling the hydrodynamics of the OWC device placed over an undulated seabed in the presence of ocean current

Alexandria Engineering Journal
The current investigation emphasizes the mathematical modeling of the hydrodynamics associated with the oscillating water column wave energy converter (OWC-WEC) device situated above undulating bottom of the ocean in the presence of ocean currents.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Hydrodynamics of a Free Floating Vertical Axisymmetric Oscillating Water Column Device

Journal of Applied Mathematics, 2012
This paper aims at presenting a general formulation of the hydrodynamic problem of a floating or restrained oscillating water column device. Three types of first-order boundary value problems are investigated in order to calculate the velocity potential ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Hydrodynamic Responses of Floating Oscillating Water Column for Wave Energy Conversion [PDF]

E3S Web of Conferences
Wave energy is a promising renewable resource due to its high-power density, predictability, and relatively low environmental impact. Oscillating Water Columns (OWCs) have been widely investigated as wave energy converters (WECs), yet floating platforms ...

Guanosine‐Quadruplex Hydrogels as Dynamic, Mechanically Tunable and Ion Conductive 3D Scaffolds for Cell Culture Applications

Advanced Functional Materials, EarlyView.
Versatile guanosine‐quadruplex (GQ) hydrogels are developed as dynamic biomatrices for cell culture. These scaffolds are fabricated under mild aqueous conditions, present improved stability, tunable mechanical properties within physiological ranges; fibrillar, porous microstructure, ion conductivity, and cytocompatibility.

Dynamic Response Analysis of Jacket Platform Integrated With Oscillating Water Column Device

Frontiers in Energy Research, 2020
For the marginal oilfield with low oil extraction, adding wave energy conversion device integration to the jacket platform is very meaningful for reducing the mining cost. First, the design concept of integrated oscillating water column (OWC) device with

Performance Analysis of a 3D Axisymmetric Oscillating Water Column

Energy Procedia, 2014
AbstractThis paper presents an analysis, by numerical simulation, of the effects of some geometric parameters on the efficiency of an axisymmetric oscillating water column wave energy converter by using ANSYS ICEM CFD and CFX. The study is focused, principally, on the variation of power take off size, front wall shape, air column size, wave conditions ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.
