This study was conducted to evaluate the combined effects of blanching and sonication on carrot juice quality. Carrots were blanched at 100 °C for 4 min in normal and acidified water. Juice was extracted and sonicated at 15 °C for 2 min keeping pulse duration 5 s on and 5 s off (70% amplitude level and 20 kHz frequency). No significant effect of blanching and sonication was observed on Brix, pH...

Microsized aerogels were prepared from epoxidized natural rubber (ENR)/polyvinyl chloride (PVC) matrix blend using the solvent exchange method and dropping technique with sonication. Some parameters were manipulated in order to observe its effects on resultant aerogels. Parameter studied were ENR/PVC solution viscosity, ratio of ENR/PVC solution to EtOH/H 2 O solution and sonication time.It was...

An efficient Agrobacterium-mediate transformation method was developed by employing different duration of sonication, Agrobacterium strains, type of inoculation medium and concentrations of acetosyringone in Arya cultivar of wheat. Immature embryos were used as an explant for inoculation with Agrobacterium tumefaciens harboring the recombinant pBI121 plasmid. Among the durations of sonication t...

The effect of sonication temperature on the debundling of carbon nanotube (CNT) macro-bundles is reported and demonstrated by analysis with different particle sizing methods. The change of bundle size over time and after several comparatively gentle sonication cycles of suspensions at various temperatures is reported. A novel technique is presented that produces a more homogeneous nanotube disp...

The sonication-driven dispersion of single-walled carbon nanotubes (SWCNTs) in aqueous surfactant solution has been monitored by UV-vis-NIR spectroscopy and scanning electron microscopy. Dispersion of SWCNTs experiments reveal that the maximum concentration of dispersed SWCNTs corresponds to the maximum UV-vis-NIR absorbance of the solution. With higher surfactant concentration the dispersion r...

The aim of this work is the investigation of the effect of ultrasound treatment on the structural characteristics of carbon nanotubes (CNTs) and the consequent influence that the shortening induced by sonication exerts on the morphology, rheological behaviour and thermo-oxidative resistance of ultra-high molecular weight polyethylene (UHMWPE)-based nanocomposites. First, CNTs have been subjecte...

A new bioassay technique, sonication-assisted metalenhanced fluorescence, which is based on the combined use of ultrasound waves and metal-enhanced fluorescence (MEF), is reported. In this technique, low-intensity ultrasound waves significantly reduce the bioassay time by creating a temperature gradient between the bulk and the surface, which is thought to result in a mass transport of biomolec...

To assess the cell wall's role as a barrier to intracellular delivery, wild-type Chlamydomonas reinhardtii algal cells and mutant cells lacking a cell wall were exposed to electroporation or sonication. Flow cytometry determined intracellular uptake of calcein and bovine serum albumin (BSA) and loss of cell viability as functions of electroporation transmembrane potential and acoustic energy. E...

BACKGROUND Different research groups have identified microorganisms on breast implants by sonication with significant correlation to the rate of capsular contracture. This substantiated the hypothesis of an infectious etiology of capsular contracture. However, no clinical consequence has been drawn from these results yet. Aim of this study was to review sonication results from breast implants a...
