In this study, ultrasonication-assisted calcium carbonate scale inhibition was investigated compared with a commercial antiscalant ATMP (amino tris(methyl phosphonic acid)). The effects of varying ultrasound amplitude, pH, and duration were evaluated. formation measured based on the concentration in solution after subjecting to different conditions. Scale deposits also characterized using scann...

During the last 20 years we have witnessed an amazing increase in the application of ultrasonic energy in different fields of science. This is especially true for analytical chemistry. The number ofmanuscripts devoted to almost all kinds of analysis dealing with the uses of ultrasonic energy continues to grow year by year. As the uses of ultrasonication have become increasingly important in ana...

This study reports on the optimization of the extraction conditions of cordycepin from Cordyceps militaris by using ultrasonication. For this purpose, the orthogonal experimental design was used to investigate the effects of factors on the ultrasonic-assisted extraction (UAE). Four factors: extraction time (min), ethanol concentration (%), extraction temperature (°C) and extraction frequency (k...

Ultrasonication has been used to accelerate chemical reactions. It would be ideal if ultrasonication-assisted chemical reactions could be monitored by suitable detection tools such as mass spectrometry in real time. It would be helpful to clarify reaction intermediates/products and to have a better understanding of reaction mechanism. In this work, we developed a system for ultrasonication-assi...

Tenderness is one of the most appreciated quality characteristics in beef by consumers. Meat aging recognized natural methodology to improve tenderness beef. The current study was designed evaluate if ultrasonication able simulate (ultrasonication alone) or grant an additional effect (aging plus ultrasonication) two different methods (dry and wet) on sensory profile Longissimus lumborum muscle....

For extracting free amino acids from human leukocytes, we find that disruption of the cells by ultrasonication is more reliable than freezing and thawing. The amount of free amino acids extracted by the latter method depends on the temperature and duration of thawing. We extracted free amino acids from leukocytes of healthy men by ultrasonication and compared their concentrations in lymphocytes...

Excess wastewater sludge collected from the recycling stream of an activated sludge process is biomass that contains large quantities of polysaccharides and proteins. However, relevant literature indicates that the bio-conversion of wastewater sludge to hydrogen is limited and therefore not economically feasible. This work examined the anaerobic digestion of wastewater sludge using a clostridiu...

Dried stem bark extracts of Saraca asoca Roxb. Prepared by different extraction methods (Soxhlet, Ultrasonication assisted & Microwave assisted extraction) with ethanol 90%, ethanol 60% and acetone. The acetone extract prepared by Ultrasonication assisted extraction, showed significant antidiarrhoeal property in castor-oil induced diarrhoea in albino rats at a dose of 200 mg/kg, b.w. as compare...

1. Basal rates of glucuronidation of oestrone (guinea pig) or of 4-nitrophenol (rat or guinea pig) were not significantly altered in sealed liver microsomal vesicles, treated with the membrane-impermeant protein-modifying agent diazobenzenesulphonate at 0.5-1.0 mM. 2. Contrarily, diazobenzenesulphonate abolished the normal stimulation of glucuronidation by UDP-N-acetylglucosamine. 3. Ultrasonic...
