Ethylene oxide - Wikipedia

Ethylene oxide is a colorless gas at 25 °C (77 °F) and is a mobile liquid at 0 °C (32 °F) – viscosity of liquid ethylene oxide at 0 °C is about 5.5 times lower than that of water. The gas has a characteristic sweet odor of ether, noticeable when its concentration in air exceeds 500 ppm.

21/6/2018· Calcium-based metal-organic frameworks (MOFs) are low cost and have bio-compatible metal centers, but the Ca local environment is often poorly understood. Although very challenging due to 0.135 % natural abundance, 43 Ca solid-state NMR at a high magnetic field of 21.1 T can probe the local structure of the Ca center in MOFs, investigate the presence of guests, and monitor phase changes.
