This paper reports preliminary results of simple experiments carried out to study the effects of microwave irradiation at 2.45 GHz on fungi, yeast and bacteria of the type encountered in food processing plants or in enclosures containing individuals infected with tuberculosis mycobacterium (TB). The results are sufficiently encouraging to justify further multivariable experiments particularly with air circulation schemes in which the air can be sterilized in a circular cylindrical microwave cavity operating at a higher order mode.

A multi-band high-sensitivity microwave sensor is reported. The two resonance units are based on complementary square spiral resonators (CSSRs) and produce four measurement bands through parasitic resonances. The four frequency bands are 2.

Alternatives to nonbiodegradable synthetic plastics for food packaging include films made from biopolymers that are nontoxic and environment-friendly. In this study, carnauba wax (CW) and nitrogen-doped graphene quantum dots (NG) as functional additives were utilized in the production of pectin/gelatin (PG) film. NG was synthesized through the microwave method, using acetic acid as the carbon source, giving size, and zeta potential of 1.

Research Background: Green extraction technologies, such as microwave-assisted extraction, have been used to replace conventional methods of isolating essential oils from plants. In this study, the essential oil was extracted from the variety koseret using the advanced method of microwave-assisted hydrodistillation. The main objective was to investigate the effect of irradiation time, microwave power and particle size on the yield and chemical composition of the essential oil extracted from leaves dried in an oven at 50 °C and room temperature.

Background: Antibiotic resistance of many bacteria, including Methicillin-resistant (MRSA), has become a major threat to global health. Zinc Oxide Quantum dots (ZnO-QDs) show good antibacterial activity, but most of them are insoluble in water, limiting their application range, and there is a lack of research on drug resistance inducement.
Methods: The water-soluble zinc oxide quantum dots modified by APTES (ZnO@APTES QDs) were prepared by a microwave assisted synthesis.
Morphology control of electrically conductive metal-organic frameworks (EC-MOFs) can be a powerful means to tune their surface area and carrier transport pathways, particularly beneficial for energy conversion and storage. However, controlling EC-MOFs' morphology is underexplored due to the uncontrollable crystal nucleation and rapid growth kinetics. This work introduces a microwave-assisted strategy to readily synthesize Cu-HHTP (HHTP = 2,3,6,7,10,11-hexahydroxytriphenylene) with controlled morphologies.
