Is there a comparative study about how the presence of nanoparticles in a polymer affects light and ultrasonic propagation?

Especially when the particles occupy the free volume of the polymer. Both kinds of wave propagation are affected by different material properties (refractive index, acoustic impedances, etc.) and...

Is there any rigid casting resin with density < 500 kg per cubic meter, without foam (either open or closed pore) structure?

Density of most casting resins is about 1000 kg per cubic meter, and it seems that only foams can provide significantly lower densities. Is this true?

Why does the ultrasonic velocity measured by Jajam et al. in epoxy loaded with silica particles increase with the volume fraction (range (0-10%)?

Normally, ultrasonic velocity in polymer loaded particles (with low particles volume fraction) decreases when the particle volume fraction increases. This is due to the fact that at low volume...
