The sonodynamically induced antitumour effect of chloroaluminum phthalocyanine tetrasulfonate (AlPcTS) was evaluated on subcutaneously implanted colon 26 carcinoma. A time of 24 h after the administration of AlPcTS was chosen for the ultrasonic exposure, based on the analysis of the AlPcTS concentrations in the tumour, plasma, skin and muscle. The pharmacokinetic analysis showed much faster cle...

The influence of ultrasonic pretreatment prior to vacuum drying of Chinese fir specimens was examined in this work. In the pretreatments, wood samples were immerged in a distilled water bath and were treated using two wave frequencies for four different elapsed times to investigate effects of ultrasonic frequency and treatment duration. Then the wood samples were vacuum-dried at 80°C and absolu...

nano dithiocarbamate (dtc) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. reaction conditions such as the ligand dtc and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. the dithiocarbamate complex nanoparticles have been pre...

In this study, applications of ultrasound in food drying processes have been reviewed. High frequency ultrasonic treatment can be used in food drying processes as a pretreatment or for the improvement of the main process and the traditional driers. Ultrasonic waves at low frequency can also be used as a diagnostic method for measuring properties of the final dried products and controlling the d...

The paper is devoted to study the ultrasonic impact on the biomass of natural raw materials, which were used for the creation a nanoporous carbon material (NCM), which was used as electrode material for electrochemical capacitors (EC). The dry shells of apricot seeds were a feedstock, which were modified by the chemical treatment in the phosphoric acid and part of them were impacted by ultrason...

This paper summarizes fatigue test on high strength steel specimens in the as-welded condition and specimens treated by ultrasonic impact treatment, TIG dressing and a combination of TIG dressing and ultrasonic impact treatment. Single lap joint specimens in 6 mm aluminium plate material were tested in the as-welded, hammer peened, needle peened and ground condition. Aluminium joints with longi...

Abstract The machinability of Ti-6Al-4V alloy has been a constant challenge in the industry, although material is widely used aerospace and medical industries due to its mechanical properties, particularly strength-to-weight ratio. current research presents hybrid laser- ultrasonic-assisted machining (LUAM) technique improve turning process. This compared with (UAM), laser-assisted (LAM), conve...
