Sonication improved the diagnosis of orthopedic implant-associated infections (OIAI). We investigated the diagnostic performance of sonication fluid inoculated into blood culture bottles in comparison with that of intraoperative tissue and sonication fluid cultures. Consecutive patients with removed orthopedic hardware were prospectively included and classified as having OIAI or aseptic failure...

Sonication process is regularly adopted for dispersing single-walled carbon nanotubes (SWCNTs) in an aqueous medium. This can be achieved by either covalent functionalization of SWCNTs with strong acid or by noncovalent functionalization using dispersants that adsorb onto the surface of SWCNTs during dispersion. Because the dispersion process is usually performed using sonication, unintentional...

The influence of tip sonication duration on the spectral characteristics of carbon single-walled nanotubes (SWNTs) in aqueous suspension with single-stranded DNA (ssDNA) has been studied by NIR luminescence, NIR absorption, and Raman spectroscopy. It was revealed that prolongation of sonication leads to weakening of the SWNT polymer coverage and appearance of additional defects on the nanotube ...

The entry of mercaptans into the environment as an odor pollutant has always been considered as one of the environmental concerns. In this research, a sonochemical oxidation (sono-Fenton) method was used for rapid deodorizing of tert-butyl mercaptan (TBM) contaminated soil. The design of the experiments was conducted by CCD method and the effect of four different factors was investigated on the...

BACKGROUND Sonodynamic therapy (SDT) is a new approach for cancer treatment. Repair by reoxygenation induces cell damage in all treatment which uses photo- and sonosensitizers. In this study, the in vivo antitumor effect of dual-frequency sonication is investigated at low-level intensity and hematoporphyrin (Hp). It is used for the treatment of spontaneous breast adenocarcinoma of Balb/c mice w...

The recently reported amphiphilic chelate, [Gd(EPTPAC16)(H2O)]2-, forms supramolecular aggregates in aqueous solution by self-assembly of the monomers with a relaxometrically determined critical micellar concentration (CMC) of 0.34 mM. The effect of sonication on the aggregate size was characterized by dynamic light scattering and relaxometry, indicating the presence of premicellar aggregates a...

Sonication has been used in many studies that require observation of the cells of Microcystis aeruginosa. This study investigates the extent to which sonication (42 kHz, 150 W) destroys live and Lugol-fixed cells of M. aeruginosa, using two strains (NIES-1090 and NIES-1157). Live cells were easily destroyed by sonication regardless of growth stage. Sonication for 50 s caused up to 32.8% (NIES-1...

Common dispersion methods such as ultrasonic sonication, planetary centrifugal mixing and magnetic dispersion have been used extensively to achieve moderate exfoliation of nanoparticles in polymer matrix. In this study, the effect of adding three roll milling to these three dispersion methods for nanoclay dispersion into epoxy matrix was investigated. A combination of each of these mixing metho...

background and objectives: preparation and evaluation of nanocomposite films have become prevalent in recent years. one of the most important methods for dispersing nanoparticles in polymers is the use of ultrasound radiation. polyvinyl alcohol-montmorillonite (pva-mmt) nanocomposite films were prepared via solvent casting method. materials and methods: the effects of different ultrasound times...
