The complex chemistry of making paper
Apr 4, 2023 · Performance-enhancing chemicals address the process chemistry side of manufacturing, ensuring that each stage runs smoothly. Defoamers and dispersants tackle practical issues such as foaming and clumping in the pulping vats, while cleaning and descaling treatments ensure water quality meets the required standards.
One-electron covalent bond between two carbons pushes limits of …
Oct 4, 2024 · ‘The strategy … involves stretching the bond in the parent molecule and tuning the energies of the molecular orbitals,’ says Cate Anstöter, a research fellow at the University of Edinburgh who was not involved in the study.‘It’s a real …
ChemSpider | Review | Chemistry World
Oct 2, 2009 · ChemSpider is a chemistry search engine, aggregating and indexing chemical structures and their associated information into a single searchable repository, and free at that.
Physical chemistry textbook now free to download as a ‘gift’ to the ...
May 23, 2024 · The retired Oxford professor said he had opted to give the e-book away – as part of a special collaboration with the Royal Society of Chemistry (RSC) – as a ‘gift and a thanks to the community’ who have given his other books a ‘loyal following’ over the years.
Explainer: The science of alkyl nitrites aka poppers
Sep 16, 2021 · From the 1960s onwards, poppers became established as a recreational drug, with various alkyl nitrites produced, including isopropyl nitrite, isobutyl nitrite and butyl nitrite, to get around legal restrictions.The drug was widely used by clubbers for a brief time in the 1990s, but plays a continued role in gay subculture.
Model explains why water can freeze at different temperatures
Mar 28, 2024 · A new theoretical model has been created that shows how certain features on a surface affect the freezing point of water. This discovery could enable materials to be designed with surfaces that would make ice form more efficiently requiring less energy – something that could help make snowmaking and cloud seeding, for example, more efficient and cheaper.
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 ...
The scale of the problem of replacing ‘forever chemicals’ PFAS
Oct 10, 2024 · Some packaging contains PFAS to repel grease, for example fast food wrappers and pizza boxes. One study published last year found PFAS chemicals in single-use paper, cardboard and plant-based moulded fibre food containers from 17 countries across Africa, Asia, Europe, North America, Latin America and the Caribbean. The research team identified fluorotelomer alcohols, precursors of PFAS ...
