Mn 3 O 4 formed when any manganese oxide is heated in air above 1000 °C. [3] Considerable research has centred on producing nanocrystalline Mn 3 O 4 and various syntheses that involve oxidation of Mn II or reduction of Mn VI. [4] [5] [6]
MnO has the distinction of being one of the first compounds [4] to have its magnetic structure determined by neutron diffraction, the report appearing in 1951. [5] This study showed that the Mn 2+ ions form a face centered cubic magnetic sub-lattice where there are ferromagnetically coupled sheets that are anti-parallel with adjacent sheets.
Negative air ions (NAI) are important air component, generally referring to the collections of negatively charged single gas molecules or ion clusters in the air. They play an essential role in maintaining the charge balance of the atmosphere.

Drifting smoke particles indicate the movement of the surrounding gas.. Gas is one of the four fundamental states of matter.The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
In the gas phase, a single water molecule has an oxygen atom surrounded by two hydrogens and two lone pairs, and the H 2 O geometry is simply described as bent without considering the nonbonding lone pairs. [citation needed] However, in liquid water or in ice, the lone pairs form hydrogen bonds with neighboring water molecules. The most common ...
