Abstract:

Agarwood oil extraction is a crucial process in the agarwood industry. However, this extraction is seldom performed by communities due to its lack of profitability and the extensive duration of the process. This study aims to investigate innovative techniques such as ultrasonic and microwave-assisted maceration to enhance the yield of agarwood oil extraction. Additionally, it seeks to calculate the efficiency of time and cost by determining the life cycle cost of agarwood oil extraction. The methodology employed in this study involved conducting extractions using ultrasonic-assisted maceration

Abstract:

Background: Benzoxazole, containing a 1,3-oxazole system fused with a benzene ring, has a profound effect on medicinal chemistry research owing to its important pharmacological activities. On the other hand, the benzoxazole derivative has exhibited important properties in material science. Especially in recent years, microwave-assisted synthesis is a technique that can be used to increase diversity and quick research in modern chemistry. The utilization of microwave irradiation is beneficial for the synthesis of benzoxazole in recent years. In this focused review, we provide a metaanalysis of

Abstract:

Three different extraction techniques were used for aqueous extraction of anions from soil of the type Ranker that was sampled from a serpentine site. The first technique involved the use of a rotary mixer (Rotary Mixer Assisted Extraction), the second, a microwave digestion system (Microwave Assisted Extraction), with different extraction temperatures for every cycle during the procedure as follows: 50, 100 and 150 ?C. An ultrasonic bath (Ultrasonic Assisted Extraction) was used for the last technique in which the durations of the extraction process were: 10, 20, 30, 40 and 50 min. The concen

Three different techniques were applied for the aqueous extraction of anions from coal and fly ash: rotary mixer- and ultrasonic-assisted extraction with different duration time, and microwave-assisted extraction at different temperatures. Validation showed that the ion-chromatographic method was suitable for the analysis of anions in coal and fly ash extracts. The variations in the amounts of anions using different extraction times during rotary-assisted extraction were minimal for all investigated anions. The efficiency of ultrasound-assisted extraction of anions from coal depended on the so

Pyrazoline compounds are extensively used in organic synthesis because of their stable nature and ability to synthesize new compounds with various biological activities. Different methods can be employed to synthesize pyrazole derivatives, including ultrasonic irradiation, microwave irradiation, ionic liquids, and grinding techniques. In traditional heating methods, an oil bath or hot plate is used as a source of heat for a chemical reaction. In microwave-assisted synthesis, dipolar polarization and conduction are the basic mechanisms observed. Microwave-assisted synthesis provides numerous be

These reviews focus on synthesizing Schiff bases and transition metal complexes using a microwave-assisted method. This method is rapid, efficient, clean and ecologically caring. The special method provides several advantages: environmental friendliness, simple work-up procedure, short reaction times, non-hazardous and excellent yields. The microwave-assisted method has become a new and rapidly growing area in man-made organic chemistry. In many cases, reactions that normally require many hours at reflux temperature under classical conditions can be completed in a microwave oven within several

Abstract:

Microwave irradiation of tissue during fixation and subsequent histochemical staining procedures significantly reduces the time required for incubation in fixation and staining solutions. Minimizing the incubation time in fixative reduces disruption of tissue morphology, and reducing the incubation time in staining solution or antibody solution decreases nonspecific labeling. Reduction of incubation time in staining solution also decreases the level of background noise. Microwave-assisted tissue preparation is applicable for tissue fixation, decalcification of bone tissues, treatment of adipos
