Protein design and structure prediction wins chemistry Nobel prize. By Jamie Durrani. David Baker, Demis Hassabis and John Jumper were rewarded for creating computational tools to design proteins and predict their structures that have ‘revolutionised biological chemistry’.
The complex chemistry of making paper
Apr 4, 2023 · From the moment wood begins its journey to becoming paper, complex chemistry carefully controls every parameter. ‘The paper industry is a $300 billion [£240 billion] industry worldwide and it uses about $40 billion of chemicals in it,’ explains Thomas. ‘These chemicals can be categorised into two areas: performance enhancement and ...

Explainer: The chemistry of farts | News | Chemistry World
Dec 21, 2016 · Consequently, De Lacy Costello and his colleagues have moved beyond the most common gases to studying volatile compounds released from faeces in very low concentrations. 6 Initially, they mimicked conditions in the large intestine by mixing faeces and nutrient medium in a container. They absorbed volatile chemicals onto plastic fibres above the mixture or pumped out through a tube, to be ...
Explainer: The science of alkyl nitrites aka poppers
Sep 16, 2021 · Inhaling alkyl nitrites feels like becoming instantly drunk according to some users, although the effect lasts for only a few minutes. Also known as poppers, these chemicals have been taken recreationally since the 1960s. Although they are sold openly, usually in small brown bottles with enticing brand names such as ‘liquid gold’, their ...
What it takes to make a new element | Feature | Chemistry World
Nov 30, 2016 · Results of fusion reactions were decreasing sharply as the atomic number grew higher. The cause was the high excitation energy (40–50MeV), which increased the chance of the element breaking up. To create new elements, the excitation energy needed to be minimal, or …
Explainer: How a new element gets its name - Chemistry World
Nov 30, 2016 · New elements must be named after a mythological concept or character (including an astronomical body), a mineral, a place or geographical region, an elemental property or a scientist. In 2002, Iupac recommended that any new metallic element must end with the suffix ‘ium’ – think chromium or titanium.
Why are there 20 amino acids? | Feature | Chemistry World
Sep 17, 2018 · But the selection of the 20 amino acids used in biology is clearly linked to the development of proteins. By polymerising amino acids in long polypeptide chains, proteins could fold into soluble structures with close-packed cores and ordered binding pockets. The arrival of proteins and the eventual adoption of the standard 20 amino acids was ...
What is an element? | Feature | Chemistry World
Jan 10, 2019 · Iupac currently gives a double definition of ‘element’ in its ‘Gold Book’ of chemical terminology, which says that the word can refer either to a ‘species of atom’ (which Ghibaudi sees as akin to Paneth’s ‘basic substance’) or, rather tautologically, to a ‘pure elementary substance’. This double meaning is uncomfortable.
