  2. Activated carbon - Wikipedia

    en.wikipedia.org/wiki/Activated_carbon

    Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed ( activated ) to have small, low-volume pores that greatly increase the surface area [ 1 ] [ 2 ] available for adsorption or chemical reactions . [ 3 ] (

  3. Electromagnetic absorption by water - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_absorption...

    The spectrum of ice is similar to that of liquid water, with peak maxima at 3400 cm −1 (2.941 μm), 3220 cm −1 (3.105 μm) and 1620 cm −1 (6.17 μm) [14] In both liquid water and ice clusters, low-frequency vibrations occur, which involve the stretching (TS) or bending (TB) of intermolecular hydrogen bonds (O–H•••O).

    The charcoal filter is usually found near the top of the microwave behind a vent grill but use your owner’s manual to confirm the location. The grease filter is located underneath the microwave ...

  5. Charcoal - Wikipedia

    en.wikipedia.org/wiki/Charcoal

    Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln , the heat is supplied by burning part of the ...

    The charcoal has 'pores' that absorb odors and if you wash filters, it breaks down the pores and releases all of the particles that were trapped back into the air," Bauer explained.

    Putting a non-microwave-safe material in a microwave oven can lead to chemicals leaching into your food (not good) or the melting of the container, which can lead to burns — or, at the very ...

  8. Microwave chemistry - Wikipedia

    en.wikipedia.org/wiki/Microwave_chemistry

    Specific microwave effects are those effects that cannot be (easily) emulated through conventional heating methods. Examples include: (i) selective heating of specific reaction components, (ii) rapid heating rates and temperature gradients, (iii) the elimination of wall effects, and (iv) the superheating of solvents.

  9. Non-thermal microwave effect - Wikipedia

    en.wikipedia.org/wiki/Non-thermal_microwave_effect

    Non-thermal effects in liquids are almost certainly non-existent, [1] [2] as the time for energy redistribution between molecules in a liquid is much less than the period of a microwave oscillation. A 2005 review has illustrated this in application to organic chemistry, though clearly supports the existence of non-thermal effects. [ 3 ]
