Co-emission of volcanic sulfur and halogens amplifies volcanic effective radiative forcing [PDF]

Atmospheric Chemistry and Physics, 2021
The evolution of volcanic sulfur and the resulting radiative forcing following explosive volcanic eruptions is well understood. Petrological evidence suggests that significant amounts of halogens may be co-emitted alongside sulfur in some explosive ...

Bilirubin Oxidase from Myrothecium verrucaria Physically Absorbed on Graphite Electrodes. Insights into the Alternative Resting Form and the Sources of Activity Loss. [PDF]

PLoS ONE, 2015
The oxygen reduction reaction is one of the most important chemical processes in energy converting systems and living organisms. Mediator-less, direct electro-catalytic reduction of oxygen to water was achieved on spectrographite electrodes modified by ...

Anomalous Fluctuation of Halogens in Relation to the Pollution Status along Lake Mariout, Egypt

Journal of Chemistry, 2020
This paper aimed to study the anomalous fluctuation of halogens with respect to the pollution status in surface water (w), pore water (p), and sediments (s) of Lake Mariout.

An Investigation of 5-Halogenated N-Indolylsulfonyl-2-fluorophenol Derivatives as Aldose Reductase Inhibitors [PDF]

Medicines
Background/Objectives: Diabetes mellitus is a group of chronic metabolic disorders characterized by persistent hyperglycemia. Aldose reductase, the first enzyme in the polyol pathway, plays a key role in the onset of long-term diabetic complications ...

Synthesis and Comparison of the Flame-Retardant Properties of Phosphorylated-Coumarins and Phosphorylated-Isophosphinolines [PDF]

Molecules
This study focuses on the synthesis, properties, and comparative analysis of new flame-retardant compounds: coumarins and isophosphinolines. These compounds feature a diarylphosphine oxide (DAPO) substituent at the β-position relative to both the ...

Natural short-lived halogens exert an indirect cooling effect on climate

Nature, 2023
Observational evidence shows the ubiquitous presence of ocean-emitted short-lived halogens in the global atmosphere^ 1 – 3 . Natural emissions of these chemical compounds have been anthropogenically amplified since pre-industrial times^ 4 – 6 , while, in

Reactive halogens increase the global methane lifetime and radiative forcing in the 21st century

Nature Communications, 2022
CH4 is the most abundant reactive greenhouse gas and a complete understanding of its atmospheric fate is needed to formulate mitigation policies. Current chemistry-climate models tend to underestimate the lifetime of CH4, suggesting uncertainties in its ...

Halogen–Halogen Nonbonded Interactions [PDF]

ACS Omega, 2021
Halogen-halogen nonbonded interactions were studied for methyl halides and phenyl halides using both B3LYP and MP2 along with 6-311+G* and aug-cc-pVTZ. With the methyl halides, the linear approach was found to lead to little stabilization, whereas the "90°" approach gave 1-2 kcal/mol. This modest stabilization was due to long-range electron correlation

Halogens in Seaweeds: Biological and Environmental Significance

Phycology, 2022
Many marine algae are strong accumulators of halogens. Commercial iodine production started by burning seaweeds in the 19th century. The high iodine content of certain seaweeds has potential pharmaceutical and nutritional applications.

Halogens Enhance Haze Pollution in China

Environmental Science and Technology, 2021
Severe and persistent haze events in northern China, characterized by high loading of fine aerosol especially of secondary origin, negatively impact human health and the welfare of ecosystems. However, current knowledge cannot fully explain the formation
