The aim of this study is to investigate the application ultrasound in extraction betanin from beets (Beta vulgaris) using Deep eutectic solvents (DES). process was optimized response surface methodology. time variable found be correlated with performance. Three DES (choline chloride: urea (CC:U), choline glycerol (CC:G), and citric acid (CC:Ac)) were studied. concentration extracted CC:U, CC:G,...

Ultrasound-assisted extraction and direct analysis were compared with total digestion for magnesium determination in beer samples by flame atomic absorption spectrometry. The method used concentrated nitric acid under plate heating. In optimized instrumental conditions, validation of the analytical was promoted, good linear range (0.06 to 0.5 mg L�1), low limits detection quantification (0.04 0...

Electromagnetic induction of ultrasonic waves is restricted to conducting materials – like eddy current testing – because it involves inducing eddy currents in the surface of the part by a nearby coil of wire. A magnetic field supplied by a nearby magnet interacts with this eddy current to produce a mechanical force on the surface to excite ultrasonic vibrations. The same configuration of coil ...

Under oxidative stress conditions, which are defined as the deterioration of antioxidant and prooxidant balance in organism favor prooxidants, ROS species that trigger formation various diseases occur. The fact these harmful cause damage to biological macromolecules is expressed activity. In this study, Cu(II)‒catalyzed activities pomegranate, apricot, peach, pear juices extracts mint, white te...

Designing a Remote Smart Home Monitor Based on the Internet of Things (IoT) using NodeMCU ESP32 microcontroller as wifi network provider and also utilizing Firebase Technology data storage medium. This remote smart home monitor with concept is safe because only people who have certain access can control appliances such turning lights, fans, opening doors, filling water in bath, preventing theft...

In this study, we have developed a new ultrasonic synthesis method of dibenzoepines using olanzapine and quetiapine, which are well-known drugs for the treatment schizophrenia bipolar disorder. The is based on N-alkylation reaction piperazine fragment in tricyclic compounds with methyl iodide or 2-(2-chloroethoxy)ethanol as alkylating agent, respectively. reactions were carried out an bath solv...

Abstract This study aims to examine the effect of ultrasonic-assisted extraction method on yield oil and profile fatty acid from microalga yeast. The cultivated was identified genetically as Thraustochytrium multirudimentale MAST-1 yeast Rhodotorula mucilaginosa KAST-1. oils were extracted dried biomass by solvents using modified Bligh Dyer (BD) method. Before extraction, material underwent ult...

This paper deals with the possible field of application ultrasonic Surface Reflection Method (SRM) to achieve mechanical characteristics isotropic materials. method is based on measurement amplitude reflected wave at interface between reference material and be characterised. Objective: The purpose Part 1 this establish theoretical conditions for applicability SRM. First, formulas necessary obta...
