A long standing area of research is that of stannanes, or organotin compounds, that were first discovered almost 200 years ago and continue to be relevant in industry and academia today. Although the mono- and tetra- substituted derivatives of tin are relatively non-toxic, di- and especially tri- organotin compounds can have serious adverse effects on the human body as well as the environment.
Merry Christmas! As we relax and unwind this holiday season, look out the window and observe the falling of snowflakes (if you’re fortunate enough to be able to!). Each icy crystal begins its existence high up in the atmosphere and slowly alters its appearance as it falls but always retaining its hexagonal structure, nature ever the master craftsman… Continue reading “Christmas Special: Snowflake Chemistry”
Beneath the surface of the oceans, there is silence. Rarely disturbed, it is often forgotten that sound travels through water four times faster than in air. Whales however never forget, and have taken advantage of this, using low amplitude vocalizations that can be heard many kilometers away. But do these ‘songs’ carry a purpose? Or do whales simply like singing in the shower, so to speak?
A cow farts, and the earth warms. Atmospheric and environmental chemistry is becoming ever more relevant in this day and age; since the Montreal Protocol in 1989 began to phase out the use of CFCs, people have realized that climate change is something that we humans are able to influence.
But seriously, how much of an impact can cows have on climate change…?
