Hydroelastic Response of a Flexible Submerged Porous Plate for Wave Energy Absorption

open access: yesJournal of Marine Science and Engineering, 2020
The application of flexible horizontal porous structure has a significant impact on the design of breakwaters and wave energy absorption devices for coastal protection and wave energy extraction, respectively.

Surge forces of a FPSO at Lee side of submerged plate in regular waves [PDF]

open access: yes, 2008
A submerged horizontal plate type breakwater is not only to be good energy dissipates of wave breaking on the top of the plate, but also to generate steady flow and to reproduce shorter waves. This paper assessed a submerged plate which is applied to set

Transient Laser‐Shocked Synthesis of Amorphous Layer‐Supported Metal Nanocrystals for Efficient Nitrate Reduction

open access: yesAdvanced Materials, EarlyView.
A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...

Transmission and Reflection of Sound by Plates Submerged in Water [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1969
Techniques described at the 1967 Miami meeting have been refined and developed sufficiently to portray clearly the effects of both angle and frequency on the transmission and reflection of sound by submerged plates of various materials. The equipment permits quantitative results to be obtained from magnetic tape recording of analog signals but current ...

A quantitative study of the relationships between morphology, physiology and geldanamycin synthesis in submerged cultures of Streptomyces hygroscopicus var. geldanus [PDF]

open access: yes, 2008
Microbially produced secondary metabolites such as antibiotics have tremendous economic importance. However, most are produced by filamentous organisms which exhibit diverse growth patterns presenting challenges for industrial fermentation.

High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

open access: yesAdvanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Endoglucanase production by endophytic fungi isolated from Vitis labrusca L. with peanut hull and sawdust as substrates

open access: yesBioscience Journal, 2019
Endoglucanases are enzymes widely employed in different industrial fields, albeit with high production costs. Studies on new microbial sources and low-cost substrates are highly relevant, including those on agro-industrial.

Use of agro-industrial wastes as substrates for α-amylase production by endophytic fungi isolated from Piper hispidum Sw

open access: yesActa Scientiarum: Technology, 2017
Millions of tons of corn, pineapple, sugarcane and wheat are annually produced and their industrial processing generates large amounts of wastes. Current study evaluated the use of corncob (CC), pineapple peel (PP), sugarcane bagasse (SB) and wheat bran (

Measurement of the shear wave speed in a submerged plate

open access: yesJournal of Physics: Conference Series, 2009
This paper develops an inverse method to estimate, in water, the shear wave speed in an isotropic, thick, elastomeric plate. The submerged plate is mechanically shaken and a scanning laser vibrometer is used to measure normal velocity on one surface. The temporal domain measurements are transformed into the frequency domain using a Fourier transform ...

Neutron Reflectometry and Compression of Graded Hydrogel Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Highly‐entangled and covalently‐crosslinked hydrogels with thin and thick surface gel layers are compressed in neutron reflectometry experiments. Surface gel layer thickness dictates the extent to which the polymer network at the surface of a hydrogel collapses, while crosslinking chemistry, and therefore elastic modulus, impacts the pressure at which ...
