Explainer: The chemistry of farts | News | Chemistry World
WEBDec 21, 2016 · Most of the gases we release from our bowels are odourless, with up to a quarter being simply oxygen and nitrogen from swallowed air. Although – as you’ll have smelled – farts differ greatly from person to person, around three quarters is carbon dioxide, hydrogen and methane produced by our gut flora. Only a third of us have methane ...
Hydrothermal vents and the origins of life - Chemistry World
WEBApr 16, 2017 · In 1977, the first deep sea hydrothermal vent was discovered in the East Pacific Rise mid-oceanic ridge. Named ‘black smokers’, the vents emit geothermally heated water up to 400°C, with high levels of sulfides that precipitate on contact with the cold ocean to form the black smoke. This was followed in 2000 by the discovery of a new type ...
What is a molecule? - Chemistry World
WEBJan 28, 2016 · Calling a ‘molecule’ an indivisible unit of a compound reflects chemistry’s historical focus on pure substances – on purifying and characterising bulk compounds. But chemistry really comes into its own in mixtures – including the incredible, organised complexity of the cell. The molecule is a necessary construct for analysis, but ...
What it takes to make a new element | Feature - Chemistry World
WEBNov 30, 2016 · Finally, you have to separate the single atom you’ve produced from the huge amounts of unreacted material and unwanted byproducts and get it to the detector. Then, by recording the chain of alpha decays emitted as the atom disappears into a cascade of lighter elements, you can prove what you’ve created. In short, creating a new element is the equivalent of shooting a machine gun at a ...

WEBSep 21, 2020 · Human chemical communication. Nina Notman sniffs out the evidence for human pheromones and chemical cues. In the 1870s, French entomologist Jean Henri Fabre detected the first evidence for chemical communication. A female emperor moth was placed in a box, and then removed a few hours later. …
The father of the periodic table - Chemistry World
WEBJan 2, 2019 · A century and a half ago, Dmitri Mendeleev took a crucial step in this search for order among the elements, by publishing the first draft of his periodic table. In 2019 the world-wide community of chemists is celebrating this anniversary, and rightly so. Like Stonehenge, the table reflects regularities in nature which were due to causes that ...
What is an element? - Chemistry World
WEBJan 10, 2019 · As chemical concepts go, you don’t get much more fundamental than the element. It’s one of the first ideas that the chemistry student encounters, often in the iconic tabulation of these basic ingredients of nature that Dmitri Mendeleev first described 150 years ago and which is being celebrated this year. And yet no one can say quite what an element is. The question was debated with much ...
