Bromine speciation and partitioning in slab-derived aqueous fluids and silicate melts and implications for halogen transfer in subduction zones [PDF]

Solid Earth, 2020
Understanding the behavior of halogens (Cl, Br, and I) in subduction zones is critical to constrain the geochemical cycle of these volatiles and associated trace metals, as well as to quantify the halogen fluxes to the atmosphere via volcanic degassing ...

Speciation and cycling of iodine in the subtropical North Pacific Ocean

Frontiers in Marine Science
Iodine intersects with the marine biogeochemical cycles of several major elements and can influence air quality through reactions with tropospheric ozone.

1,4‐Brook Rearrangement of β‐Silyl Allylic Alcohols: Trisubstituted Alkenes by Copper‐Mediated Stereoretentive ipso‐Substitution Reactions

Angewandte Chemie, Volume 138, Issue 44, 26 October 2026.
To fully leverage the power of the ruthenium‐catalyzed trans‐hydrosilylation of propargyl alcohols, it was necessary to develop a practical and robust method for the activation of those products that carry the silyl group distal to the hydroxy substituent.

Heterogeneous Iodine Chemistry Impacts Reactive Halogen and Oxidant Abundances

Geophysical Research Letters
Tropospheric reactive halogens influence the oxidizing capacity of the atmosphere. Although previous studies have shown that iodine exerts the strongest impact on tropospheric ozone concentrations compared to chlorine and bromine, the impact of aerosol ...

The Complete Plastid Genomes of Seven Sargassaceae Species and Their Phylogenetic Analysis

Frontiers in Plant Science, 2021
Sargassum is one of the most important genera of the family Sargassaceae in brown algae and is used to produce carrageenan, mannitol, iodine, and other economic substances. Here, seven complete plastid genomes of Sargassum ilicifolium var. conduplicatum,

Observations of iodine speciation and cycling in the hydrosphere [PDF]

, 2008
Iodine is an important element in oceanic, atmospheric, and terrestrial systems. Firstly, radical reactions in the troposphere can lead to significant ozone depletion, and secondly, nucleation of gaseous iodine molecules can produce new aerosol formation events, presenting possible direct and indirect natural cooling effects on climate.

High (but Not Low) Urinary Iodine Excretion Is Predicted by Iodine Excretion Levels from Five Years Ago [PDF]

, 2011
Background: It has not been investigated whether there are associations between urinary iodine (UI) excretion measurements some years apart, nor whether such an association remains after adjustment for nutritional habits. The aim of the present study was

Quantification and Speciation of Iodine-129 in Hanford Tank Waste [PDF]

, 2020
The Hanford site, located in Richland, WA, was utilized for plutonium production during World War II. During operation, 2 million m3 of waste were generated, much of which is still stored in tanks across 177 waste sites.
