- Sulfur hexafluoride (SF6) was used as a medium, liquefied at about 23 °C and 25 bar pressure.
- The research established the angular and frequency bandwidths for effective interaction and found that a 12 mm wide transducer provided the highest energy efficiency for the acousto-optic modulator.
Article Abstract
Acousto-optic (AO) interaction in the terahertz range was investigated with the use of monolithic ultrasound transducers of various widths. Sulfur hexafluoride (SF6) liquefied at a temperature of about 23 °C and a pressure of 25 bar was used as a medium for AO interaction. The angular and frequency bandwidths of effective AO interaction, as well as the diffraction efficiency per 1 W of the driving electric power, were determined. For the first time, a correct comparison of the AO diffraction efficiency in SF6 with the use of ultrasound transducers with different widths was carried out. In the experiments performed, the highest energy efficiency of the AO modulator was achieved with a transducer with a width of 12 mm.

Lipid nanoparticles (LNPs) based messenger RNA (mRNA) therapeutics hold immense promise for treating a wide array of diseases, while their nonhepatic organs targeting and insufficient endosomal escape efficiency remain challenges. For LNPs, polyethylene glycol (PEG) lipids have a crucial role in stabilizing them in aqueous medium, but they severely hinder cellular uptake and reduce transfection efficiency. In this study, we designed ultrasound (US)-assisted fluorinated PEGylated LNPs (F-LNPs) to enhance spleen-targeted mRNA delivery and transfection.

Fluoropolymer alone, as an alternative to lead-based piezoelectric materials, has shown multiple challenges to develop useful sensors for solving real-world problems such as photoacoustic, ultrasound pulse echo, and other non-destructive testing. This work demonstrates the fabrication of high frequency and wide bandwidth transducers with fluoropolymer and highly polarizing cubic single crystal Barium titanate (BaTiO) ceramic composite for high resolution in-vivo photo-acoustic and ultrasound imaging. For transducer fabrication, a customized bio-compatible nanocomposite sensor film of PVDF-TrFE (Polyvinylidene fluoride trifluoroethylene)/BaTiO (BTO) is synthesized by drop and dry in heating-cum-electro-poling system for advancing polarization, crystallinity, and higher charge generation.

Background: Histotripsy is a non-invasive, non-ionizing, non-thermal focused ultrasound technique. High amplitude short acoustic pulses converge to create high negative pressures that cavitate endogenous gas into a bubble cloud leading to mechanical tissue destruction. In the United States, histotripsy is approved to treat liver tumors under diagnostic ultrasound guidance but in initial clinical cases, some areas of the liver have not been treated due to bone or gas obstructing the acoustic window for targeting.
