Capillary Flows of Nematic Liquid Crystal
Crystals, 2020 In this paper we report the new experimental results on the rise of a liquid crystal in flat capillaries with inner photosensitive surfaces. The capillaries with different surface orientations were prepared by the use of the photo-alignment technique ...

Acoustic waves in granular materials [PDF]
, 2007 Dynamic simulations with discrete elements are used to obtain more insight into the wave propagation in dense granular media. A small perturbation is created on one side of a dense, static packing and examined during its propagation until it arrives at ...

Accuracy and uncertainty of single-shot, nonresonant laser-induced thermal acoustics [PDF]
, 2000 We study the accuracy and uncertainty of single-shot nonresonant laser-induced thermal acoustics measurements of the speed of sound and the thermal diffusivity in unseeded atmospheric air from electrostrictive gratings as a function of the laser power ...

Amorphization of Molecular Liquids of Pharmaceutical Drugs by Acoustic Levitation [PDF]
Physical Review X, 2011 It is demonstrated that acoustic levitation is able to produce amorphous forms from a variety of organic molecular compounds with different glass forming abilities. This can lead to enhanced solubility for pharmaceutical applications. High-energy x-ray experiments show that several viscous gels form from saturated pharmaceutical drug solutions after 10–

Investigation of a Molecular Plasma From Its Acoustic Response [PDF]
IEEE Transactions on Plasma Science, 2021 In developing a pulsed microwave lamp of 1 kW, fitted with a static electrodeless spherical bulb of glass, we discovered a phenomenon in which the plasma forms a ball at the bulb’s center, despite the effect of gravity. The light is produced by plasma of sulfur, which is so hot that it might melt the bulb if it remained in contact with the glass ...

Acoustics, 2022 Acoustic shockwaves are of interest as a possible means of the selective inactivation of viruses. It has been proposed that such inactivation may be enhanced by driving the virus particles at frequencies matching the characteristic frequency ...

A Kretschmann setup at acoustic frequencies for studying molecular vibration
New Journal of Physics, 2020 Abstract In this study, simultaneous measurement of surface plasmon resonance (SPR) and surface enhanced Raman scattering (SERS) on flat metallic surfaces was demonstrated in a setup based on the Kretschmann configuration at acoustic frequency.
