Sulphur dioxide dissolved in water exists mostly in the molecular state, the HSO 3 and HS 2 O 5 ions being formed in small amounts as a result of the equilibria[Formula: see text]There is very little interaction between SO 2 and H 2 O molecules in condensed phases....
The recent inference of sulfur dioxide (SO2) in the atmosphere of the hot (approximately 1,100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations1,2,3suggests that photochemistry is a key process in high-temperature exoplanet atmospheres4. This is because of the low (...
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...
Investigating the influence of sulphur dioxide (SO2) on the stable isotope ratios (δ13C and δ18O) of tree rings Direct, quantitative correction for the SO 2 effect represents a significant challenge owing to the nature of the records and likely local plant response ... KT Rinne,NJ Loader...
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. 1957 .

Photoinduced hidden monoclinic metallic phase of VO2 driven by local nucleation Vanadium dioxide exhibits an insulator-to-metal transition when exciting by a laser. Here, the authors show the transition arises from the dissociation of local V-V dimers and show the existence of the monoclinic metal...

Atomic Physics and Related Subjects.: Communications to Nature.: Raman Effect for Solutions of Sulphur DioxideSTUDIES of the Raman effect for hydrogen chloride and for ammonia as gases, as liquids, and in aqueous solution have been made by various investigators. With ammonia, the same modified ...
Stable isotopes are alternative forms of elements with different molecular weights that are found naturally and do not decay radioactively. Stable isotope analysis of elements such as carbon, nitrogen and sulphur is used in ecology to trace the flow of nutrients through food webs and assess trophic...
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...
