Journal ArticleDOI
Imaging of photoacoustic-mediated permeabilization of giant unilamellar vesicles (GUVs).
Diogo A. Pereira,Alexandre Silva,Patrícia A.T. Martins,Ana P. Piedade,Dmitro Martynowych,David Veysset,David Veysset,Maria João Moreno,Carlos Serpa,Keith A. Nelson,Luis G. Arnaut +10 more
TL;DR: In this paper, photoacoustic wave propagation and interaction with unilamellar vesicles was shown to promote the release of FITC-dextran or GFP from GUVs without damage.
Reference EntryDOI
Impulsive Stimulated Thermal Scattering
TL;DR: Impulsive stimulated thermal scattering (ISTS) is a purely optical, non-contacting method for characterizing the acoustic behavior of surfaces, thin membranes, coatings, and multilayer assemblies, as well as bulk materials as mentioned in this paper.
Proceedings ArticleDOI
Studies of Perovskite Materials for High-Performance Storage Media, Piezoelectric, and Solar Energy Conversion Devices
Tingting Qi,Ilya Grinberg,Joseph W. Bennett,Young-Han Shin,Andrew M. Rappe,Ka-Lo Yeh,Keith A. Nelson +6 more
TL;DR: In this paper, the lower limit for tetragonal PbTiO$ 3$ polarization switching time period is on the scale of 10 pico seconds, and the structural and electronic properties of a semiconductor non-oxide perovskite BaZrS$ {3}$ are investigated in detail.
Journal ArticleDOI
Precise Determination of Thin Metal Film Thickness With Laser-Induced Acoustic Grating Technique
Alexei Maznev,M. Banet,Michael Gostein,R.B. Hanselman,M. Joffe,Robin Anne Sacco,Keith A. Nelson +6 more
TL;DR: An all-optical technique based on laser excitation and detection of surface acoustic waves is capable of precise, fast, noncontact and nondestructive measurements of metal film thickness as discussed by the authors.
Journal ArticleDOI
Photoacoustic measurements to determine acoustic velocities in shocked condensed materials: Application to liquid benzene
TL;DR: In this paper, photoacoustic measurements were used to examine structural changes in shocked materials, such as liquid benzene, which remains a liquid at pressures well above the static compression threshold for freezing.
