Experiments with deliberate microwave irradiation at reasonable levels have failed to show negative effects even over multiple generations.

High-intensity microwave irradiation of the brain can preserve brain tissue and induce death in less than 1 second, but this is currently only used on rodents.

The use of microwave irradiation reduced the reaction times.

As a result, the strength of microwave irradiation is less demanded than that in the solid effect.

This has also been accomplished in a one-pot synthesis using microwave irradiation.

It arises for example in the condensation of α,β-unsaturated ketones, malononitrile, and 4-methylbenzenethiol under microwave irradiation.

Extraction is accomplished with the aid of either microwave irradiation or ultrasound.

By these means it is possible to visualise thermal inhomogeneities within solid phases under microwave irradiation.

This technique is usually accomplished by exposing a sample to a strong acid in a closed vessel and raising the pressure & temperature through microwave irradiation.

Although microwave irradiation has been around since the late 1940s, it was not until 1986 that microwave energy was used in organic chemistry.
