    4, to yield a small percentage of neutral N 4 molecules. [7] N + 4 + CH 4 → N 4 + CH + 4. A deflecting electrode was used to remove any unreacted N + 4 ions as well as the target gas, CH 4, and any additional unintended reaction products, leaving a stream of N 4 molecules. In order to affirm the synthesis and isolation of N 4, this stream ...

    The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a vacuum pump. [2] Liquid nitrogen's efficiency as a coolant is limited by the fact that it boils immediately on contact with a warmer object, enveloping the object in an insulating layer of ...

    The largest category of nitrides are the interstitial nitrides of formulae MN, M 2 N, and M 4 N (although variable composition is perfectly possible), where the small nitrogen atoms are positioned in the gaps in a metallic cubic or hexagonal close-packed lattice. They are opaque, very hard, and chemically inert, melting only at very high ...
