Proton‐Switching Regulates Interfacial Iodine Chemistry for Long‐Life Zinc–Iodine Batteries

Angewandte Chemie, EarlyView.
A proton‐switchable imine‐linked framework is developed to dynamically regulate interfacial iodine chemistry in aqueous Zn–I2 batteries, where reversible protonation/deprotonation switches the host affinity between iodide and polyiodide species. This state‐dependent regulation suppresses shuttle‐induced side reactions while preserving fast iodine redox

Iodine speciation and cycling in fresh waters: a case study from a humic rich headwater lake (Mummelsee)

Journal of Limnology, 2009
Iodine is a vital micronutrient for all mammals, including humans. Despite iodine's listing by the WHO as the world's most easily preventable cause of brain damage, there is very little known about iodine cycling in terrestrial freshwaters, particularly ...

Speciation of ¹²⁷I and ¹²⁹I in atmospheric aerosols at Risø, Denmark: insight into sources of iodine isotopes and their species transformations [PDF]

Atmospheric Chemistry and Physics, 2016
Speciation analysis of iodine in aerosols is a very useful approach for understanding geochemical cycling of iodine in the atmosphere. In this study, overall iodine species, including water-soluble iodine species (iodide, iodate and water-soluble ...

Halogen species record Antarctic sea ice extent over glacial–interglacial periods [PDF]

Atmospheric Chemistry and Physics, 2013
Sea ice is an integral part of the earth's climate system because it affects planetary albedo, sea-surface salinity, and the atmosphere–ocean exchange of reactive gases and aerosols.

A review on speciation of iodine-129 in the environmental and biological samples [PDF]

Analytica Chimica Acta, 2009
As a long-lived beta-emitting radioisotope of iodine, (129)I is produced both naturally and as a result of human nuclear activities. At present time, the main part of (129)I in the environment originates from the human nuclear activity, especially the releases from the spent nuclear fuel reprocessing plants, the (129)I/(127)I ratios have being reached ...

Microbial Contribution to Iodine Speciation in Hanford's Central Plateau Groundwater: Iodide Oxidation

Frontiers in Environmental Science, 2020
A waste product from plutonium production at Hanford, the radioisotope iodine-129 (129I), is an environmental concern due to its long half-life, mobility, and hazardous potential to humans through bioaccumulation in the thyroid gland.

Aerosol iodine recycling is a major control on tropospheric reactive iodine abundance [PDF]

Atmospheric Chemistry and Physics
Tropospheric reactive iodine influences the oxidizing capacity of the atmosphere and serves as an important source of ultra-fine particles. However, the paucity of observations of gas-phase and aerosol iodine, combined with incomplete understanding and ...

Genome Size Variation across a Cypriot Fabeae Tribe Germplasm Collection

Plants, 2023
DNA content is an important trait linked to the evolutionary routes of taxa and often connected to speciation. In the present study, we studied C-values variation across the Cypriot Fabeae gene pool.

Modelling iodide – iodate speciation in atmospheric aerosol: Contributions of inorganic and organic iodine chemistry [PDF]

Atmospheric Chemistry and Physics, 2007
The speciation of iodine in atmospheric aerosol is currently poorly understood. Models predict negligible iodide concentrations but accumulation of iodate in aerosol, both of which is not confirmed by recent measurements.

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 ...
