Characterization of Double Leached Waelz Oxide for Identification of Fluoride Mineral

open access: yesMetals, 2019
Double leached Waelz oxide (DLWO), with 76% zinc, is a secondary zinc containing raw materials obtained by the treatment of electric arc furnace dust. The content of fluoride in DLWO is still too high for direct leaching, as fluoride has a detrimental ...

Halogen chemistry reduces tropospheric O3 radiative forcing [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Tropospheric ozone (O3) is a global warming gas, but the lack of a firm observational record since the preindustrial period means that estimates of its radiative forcing (RFTO3) rely on model calculations.

Application of Molecular Emissions in Laser-Induced Breakdown Spectroscopy: A Review

open access: yesFrontiers in Physics, 2022
Laser-induced breakdown spectroscopy (LIBS) with advantages of rapid, in situ, and little sample pretreatment has been used in various fields. However, LIBS technology remains challenging in the detection of halogens, isotopes, and samples with similar ...

Quantification of the depletion of ozone in the plume of Mount Etna [PDF]

open access: yes, 2014
Volcanoes are an important source of inorganic halogen species into the atmosphere. Chemical processing of these species generates oxidised, highly reactive, halogen species which catalyse considerable O3 destruction within volcanic plumes. A campaign of

Inter(pseudo)halogens with relevance to peroxidase-mediated reactions

open access: yesRedox Biochemistry and Chemistry, 2023
In mammals, heme peroxidases are well known to generate oxidized (pseudo)halide products such as hypochlorous acid, hypobromous acid, oxidized iodine species, and hypothiocyanite.

Halogen Bonding in Nucleic Acid Complexes

open access: yes, 2017
Halogen bonding (X-bonding) has attracted notable attention among noncovalent interactions. This highly directional attraction between a halogen atom and an electron donor has been exploited in knowledge-based drug design. A great deal of information has

Global impacts of tropospheric halogens (Cl, Br, I) on oxidants and composition in GEOS-Chem

open access: yes, 2016
. We present a simulation of the global present-day composition of the troposphere which includes the chemistry of halogens (Cl, Br, I). Building on previous work within the GEOS-Chem model we include emissions of inorganic iodine from the oceans ...
