Data describing the insertion of sulphur dioxide into the carbontin bond of a range of substituted phenyltrimethyltin compounds in methanol and benzene solvents have been reconsidered. The reaction in methanol is cleanly second order, but the reaction in benzene has both a second-order and third-...
The sulphur dioxide (SO2) emission index in kerosene varies widely around a mean value ≈1 g (kg-fuel)−1 depending on the origin of the crude oil4; most jet fuel has lower emissions. The fraction of SO2 converted to condensable sulphuric acid at emission (few %) and the mass and...
It was also shown that the present isotopic composition of oceanic sulphates could be interpreted by volcanic sulphur dioxide.doi:10.1016/0016-7037(57)90025-XSakaiHitoshiElsevier LtdGeochimica Et Cosmochimica ActaSakai, H.

What are added to food to maintain or improve the safety, freshness, taste, or appearance of food are known as food additives. Some food additives have been in use for centuries for preservation--such as salt (in meats such as bacon or dried fish),sugar, or sulphur dioxide (in wine)...

Russian-owned Nornickel is the world’s top producer of palladium and nickel and a major producer of copper, platinum, cobalt, silver and gold, supplying 37 countries. A major polluter, in 2018 the company emitted more sulphur dioxide than the entire United States37 and is responsible for the...

Electrochemically-mediated carbon capture has good energy efficiency and potential in carbon dioxide separation, but optimisation of these systems is challenging. Here, the authors report the use of isoindigo derivatives to give fine-tuned interactions with CO2 for carbon capture methods. Xing Li , Xun...
The observations of gas clouds collated for this study are from a number of different sensors on different platforms, but are dominated by observations by the OMI and the AIRS5, which quantify vertical column densities of sulfur dioxide using its characteristic absorption signature in the UV and ...
