Synthesis and characterization of Cd-TiO2/PEG/FA nanocomposite as a biomaterial is the main aim of this research. Cd-doped TiO2 nanoparticles (NPs) were synthesized by solvothermal assisted sol-gel method. Then, polyethylene glycol (PEG) was added to the as-synthesized NPs in order to modify their surface and to prevent agglomeration. In the next step, folic acid (FA) was conjugated to Cd-TiO2/...

The voltammetric behaviour of the purine base guanine and the corresponding n,.,c!eoside guanosine at a glaxgy carbon ek~rode was investigated with the help of ultrasound. The adsorption of guanine and guanosiae as well as the adsorption of tJieir ox~Kion pf~:gh~ affects the overall voltammetric characteristics dramatically. In particular, the effect of ultrasound on the simultaneous adsoq~aa o...

Background & Aim: Sesame is one of the oldest cultivated plants in the world and is one of the oldest oily products used by humans. Sesame oil is an important industrial, oral and medicinal oil. Today, the use of ultrasound has grown significantly due to its effects on food storage and processing. Experimental: In this research, the response level model w...

In this study, constraint groove pressing (CGP) process and ultrasonic assisted CGP (UCGP) process were investigated on the process forces, mechanical properties of the sheet, including hardness and tensile tests and grain size. Pure copper sheets were used as samples in this research. Samples were tested both with and without ultrasonic vibrations for mechanical properties and grain size up to...

BACKGROUND The present work was designed to appraise how different extraction solvents and techniques affect the extractability of antioxidant and antimicrobial components from Lantana camara (L. camard) flowers. MATERIAL AND METHODS Four extraction solvents including 100% methanol, 80% methanol, 100% ethanol and 80% ethanol coupled with three extraction techniques namely stirring, microwave-...

Microencapsulation techniques are widely applied in the field of pharmaceutical production to control drugs release in time and in physiological environments. Ultrasonic-assisted atomization is a new technique to produce microencapsulated systems by a mechanical approach. Interest in this technique is due to the advantages evidenceable (low level of mechanical stress in materials, reduced energ...

The paper details the effects of depth of cut and vibration amplitude when ultrasonic assisted (US) creep feed grinding Inconel 718 with an open structured alumina based wheel. The workpiece was actuated at a constant frequency (~20.5kHz) via a block sonotrode attached to a 1kW piezoelectric transducer-generator system. A full factorial experimental array comprising 12 tests was conducted invol...
