Microwave Applications in Chemistry and Industry

Dear Colleagues,

Microwave heating exploits the interaction between electromagnetic waves and materials to convert microwave energy into heat. This has resulted in the widespread use of microwave energy in industrial, scientific and medical sectors. The advantages of microwave heating compared to conventional heating are numerous; its efficiency thanks to selective heating leads to a shortened heating time, it has easily controllable temperature rise dynamics, etc. In many applications, the use of microwaves appears environmentally friendly; for example, it leads to a possible reduction in solvents and in the quantity of wastewater in microwave-assisted chemistry. Microwaves are expected to become increasingly popular, with the development of new microwave technologies solving many problems in the future, particularly in energy-intensive industrial sectors, to replace conventional heating.

The industrialization of microwave heating depends heavily on the control of two main weak points of this technology, namely the presence of hot spots, and the risk of thermal runaway. Solving these problems creates the need for (i) a better understanding of the mechanisms of interaction between electromagnetic waves and the media under treatment; (ii) the development and manufacture of dedicated equipment; (iii) the study of the electromagnetic properties of new materials. The popularization of multi-physics simulation tools, progress in the development of microwave and radio frequency equipments, and the appearance of new materials all contribute to innovative solutions for microwave power applications at both the laboratory scale and industry scale.

This Special Issue, titled “Microwave Applications in Chemistry and Industry”, aims to shows the most recent advances in the following areas:

• Microwave and RF applications in chemistry;
