Ultrasonic-assisted extraction was employed for highly efficient separation of aroma oil from raspberry seeds. A central composite design with two variables and five levels was employed and effects of process variables of sonication time and extraction temperature on oil recovery and quality were investigated. Optimal conditions predicted by response surface methodology were sonication time of ...

This paper explores the superposition of ultrasonic vibration on vertical rotating augers in a variety granular media. Ultrasonic is known to facilitate direct penetration media, and it anticipated that any related reduction torque requirements system might improve augering performance. Experimental results suggest that, compared non-ultrasonic scenario, ultrasonically assisted significantly pr...

tea is one of the most important medicinal plants which have a considerable effect on the treatment of cardiovascular disease and cancer. the drying process of tea leaves is carried out by hot air flow which consumes high level energy. the aim of the recent research was to investigate the procedure of high power ultrasound-assisted drying process of tea leaves. hybrid variety of chinese tea was...

A new method for the synthesis of nano zero-valent iron (nZVI) was developed in the present study. Ultrasonic waves, as a novel method, were used to synthesize the nanoparticles. The morphology and surface compositions of the particles were characterized by using FESEM, XRD, BET, and particle size analyzer. The synthesized nanoparticles were then utilized as a Fenton-like catalyst to degrade of...

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/...

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...

A green and efficient ionic liquid-based ultrasound-assisted in-situ solvent formationmicroextraction (IL-UA-ISFME) in combination with high-performance liquid chromatographyultravioletdetection (HPLC-UV) has been successfully developed for the trace determination offive selected polycyclic aromatic hydrocarbons (PAHs) in environmental water samples. In thismethod, a hydrophobic ionic liquid (1...
