Phycocyanin is a precious, natural, blue coloured pigment-protein complex that has commercial value and wide application in cosmetics, food, pharmaceutical industries. In the present study, we performed various cell disruption methods (ultrasonication, homogenization, freeze/thaw CaCl2 extraction) for phycocyanin extraction from different forms of biomass thermophilic Pseudanabaena sp. high pot...

The impregnation of continuous carbon fibre roving with thermoplastic melt is a challenging task due to the high viscosity and surface tension melt. A new technique under development utilizing ultrasonic oscillations within which encloses roving, achieve impregnation. Despite processing being very efficient, specific conditions created in have never been studied before. This study investigated ...

The accurate determination of trace elements in vegetable edible oils is still an analytical challenge, owing to their low concentration levels and the complex matrix oils. aim this study was develop a fast simple method quantify 45 small mass samples (0.5 g) extra virgin olive by inductively coupled plasma spectrometry. To evaluate best fastest sample preparation procedure, ultrasonic extracti...

Erythrosine B is widely used for dyeing in various applications, especially in the food industry, despite its already proved toxicity and carcinogenicity. Therefore, the purpose of this study is to evaluate the efficiency of the synthesis process of US/S2O8-2 in removing erythrosine B dye from aqueous solution. In this experimental study, the removal of erythros...

Realizing the efficacy of liquid-phase exfoliation technique to obtain a greater quantity graphene, this study demonstrates cost-effective bio-surfactant-assisted few-layer graphene (FLG) with low defect ratio. An ultrasonic bath without any toxic chemicals or chemical modification was employed exfoliate at room temperature. Several state-of-the-art characterization techniques such as TEM, AFM,...

the clinical and economic importance of heart failure is widely recognized.   the incidence of heart failure is on the increase, particularly with the aging of the population around the world.   it is time for a paradigm shift in heart failure management. alternative non-pharmacological strategies to remodel the failing ventricle will shape a major portion of heart failure therapy in the decade...
