Two Erosion Tests to Quantify Resistance to Erosion During Overflow: The Jet Erosion Test and the Overflow Test ()

open access: yes
This report presents three experimental devices for quantifying the resistance to external erosion of a dam or dike embankment during overflow. The first is the Jet Erosion Test initially developed at the Agricultural Research Service (ARS, USA), and currently used by GeophyConsult (France) and INRAE (France). The second experimental apparatus concerns

An Electrowetting Pump

open access: yesAdvanced Functional Materials, EarlyView.
A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Mechanical and Tribological Performance of Luffa cylindrica Fibre-Reinforced Epoxy Composite

open access: yesBioResources, 2015
This work focuses on the mechanical properties and solid particle impact behaviour of Luffa cylindrica fibre (LCF)-reinforced epoxy composites. Single (SL)-, double (DL)-, and triple (TL)-layered composites were prepared using the general hand lay-up ...

Comparison of Cavitation Erosion Test Results Between Vibratory and Cavitating Jet Methods

open access: yesFluid Power Systems and Technology, 1992
Abstract The relationship of the test results between the vibratory and cavitating jet methods was clarified experimentally. Six types of metallic specimens which were made of aluminum alloy, superduralumin, high-strength brass, stainless steel, carbon steel and chrome-molybdenum steel were tested.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Erosion wear behavior of NiCr+Cr3C2–NiCr coating under multi–impact angle and novel coating structure design

open access: yesJournal of Materials Research and Technology, 2021
Despite advances in NiCr + Cr3C2–NiCr coating improving the erosion wear resistance at low impact angles, the deterioration at medium and high impact angles has not been solved for the impeller subjecting to multi–impact angle.

n‐Type Polymer Radio Frequency Rectifiers Operating at 18.5 GHz

open access: yesAdvanced Materials, EarlyView.
Combining an n‐doped polymer semiconductor with wafer‐scale asymmetric planar electrodes featuring work function‐engineered contacts yields radio‐frequency diodes and rectifying circuits operating at up to 18.5 GHz. The devices combine scalable manufacturing with an operating frequency previously unattainable by large‐area organic electronics ...
