Speciation of dissolved inorganic iodine in a coastal fjord: a time-series study from Bedford Basin, Nova Scotia, Canada

Frontiers in Marine Science, 2023
We report a long-term (4.5 year) time-series with weekly resolution of iodide and iodate measurements made at 4 depths within the Bedford Basin: a 70 m deep, seasonally stratified, coastal fjord located near Halifax, Nova Scotia, Canada.

Upcycling Water Pollutants Into Long‐Chain Polymers via Synergistic Interfacial Dechlorination and Organic Radical Stabilization

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
HEO‐regulated electronic structure drives nonradical PI activation, promoting ETP‐mediated polymerization of 4CP into high‐molecular‐weight products with enhanced surface enrichment. Concurrent dechlorination occurs via radical coupling and •OHads attack, enabling efficient carbon retention and selective product evolution at the liquid–solid interface.

Rewiring Pyroptosis to Potentiate Cancer Immunotherapy via a Gasdermin D Agonist Bypassing Caspase‐3

Advanced Science, EarlyView.
This work introduces a small‐molecule agonist, DIBDO, that bypasses Casp‐3 to directly trigger GSDMD‐mediated pyroptosis in tumors. Activated by glutathione, DIBDO generates singlet oxygen and molecular iodine, blocking Casp‐3 pathways and inducing immunogenic cell death.

Substrate‐Controlled Enantiodivergence in Ni‐Catalyzed Access to Phosphorylated Oxindoles With Quaternary Stereocenters

Angewandte Chemie, Volume 138, Issue 32, 3 August 2026.
An efficient, enantiodivergent synthesis of phosphorylated oxindoles with quaternary stereocenters is achieved via a nickel‐catalyzed intermolecular Heck‐phosphorylation cascade. Employing a single chiral catalyst, either product enantiomer is selectively accessed simply by changing the alkene leaving group. DFT calculations trace this stereodivergence

Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

Advanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

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.

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,

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 ...

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.
