Dielectric and magnetic properties of polyvinylidene fluoride polymer composites highly loaded with nickel

open access: yesScience and Engineering of Composite Materials, 2012
In this work, electroactive polyvinylidene fluoride (PVDF) was a matrix for dispersing 10 wt% ferromagnetic nickel (Ni) particles. The composites were formed into its shape by using a spin coater with varying spinning speeds from 750 to 3750 rpm to ...

Dissipation of mechanical energy in fused silica fibers [PDF]

open access: yes, 1999
For thermal noise considerations of LIGO suspensions, the sources of dissipation in the suspending fibers must be analyzed. To determine the dissipation induced by the surface of fused silica fibers, we measured the quality factor of fibers having ...

Experimental Aeration Investigations on Supersaturated Total Dissolved Gas Dissipation [PDF]

open access: yesNature Environment and Pollution Technology, 2023
Supersaturation of total dissolved gas (TDG) is mainly produced by high dam discharge, excess oxygen production by plant photosynthesis, and a sharp increase in water temperature, which may directly lead to fish and aquatic organisms suffering from “gas ...
